Webhooks vs API

Webhooks vs API:

 One of the biggest and most productive ways of purchasing goods today is eCommerce. Shopping online and ordering is quick and convenient for the customer. For online stores, things are somewhat more difficult since many eCommerce applications have to be used. All these applications often need to run all the essential functions of their online shops in real-time.

For that, both webhooks and APIs come in handy for transferring data. However, they provide a slightly different value to apps. In this article, we will discuss what differs webhooks from API, and why it is important to use them for efficient integration.

What Are Webhooks?

A webhook (also called an HTTP callback) is generally initiated by some kind of event. If the event occurs, an HTTP request to the webhook URL is made from the reference site. Users can subscribe to a particular event (e.g. order status updates) and get notified every time the event occurs (e.g. the order status updates).

A webhook is the best choice for circumstances where information changes less frequently. It is a waste of bandwidth to make API calls and continuously receive the same reply, so allowing the external system to inform your eCommerce software when necessary would be much more effective. With webhooks, consumers receive real-time updates and will not have to wait to receive API polling.

Webhooks can be considered as a perfect and often even necessary complement to any API integration.

What Is An API?


The ultimate objective of any API integration is to efficiently exchange data between your eCommerce applications to provide your customers with even greater benefits.​ An API defines how your eCommerce software components can communicate and enable different, independent systems to connect and exchange information with each other. When an API is available for an eCommerce software application, it can exchange data with any application which also has an API.

If you know that information will frequently change, but you don’t need updates in real-time, an API could be the better choice.

APIs + Webhooks = Benefit

When eCommerce suppliers develop advanced SaaS software applications, they need easy ways to share information between them. The two major ways to merge systems and prevent content/information silos are webhooks and APIs, but each has its unique function, as we have seen before.

The best choice is to use both APIs and Webhooks together to create a scheme that can communicate the correct data types as necessary for your eCommerce application. With full implementation of APIs and Webhooks, data flows instantly between any eCommerce applications, increasing efficiencies and reducing manual operation errors.

Webhooks and eCommerce

As an eCommerce software supplier, you must plan to develop as often as possible and attract more potential customers. To do that, you must provide eCommerce online retailers with superior customer support and help them optimize their business processes and enhance the support they provide to their clients. You can use webhooks to extend your functional capabilities as an eCommerce application provider since webhooks are particularly useful for any eCommerce framework.

Webhooks, for example, provide major advantages over rivals in inventory management systems because of their ability to ensure stock levels are accurate and thus make real-time changes to online retailers. Webhooks thus make it possible to cope better with unforeseen demands.

In particular, the key benefits of using webhooks are:

  • To ease your way of receiving updates;
  • To ensure the synchronization of data between various eCommerce applications;
  • To connect two or more eCommerce applications where an event at one will cause an event at the second;
  • To adapt the eCommerce application features to your specifications.

API2Cart provides a unified API for B2B eCommerce software providers through which they will be able to integrate with 40+ shopping platforms and marketplaces. It provides 100+ API methods and a range of webhooks to get notifications each time the product, order, customer, or category are added or updated. With a zero-minute delay and 98% of API calls saved fresh and accurate data delivery is guaranteed.

21 Popular JavaScript Libraries Every Web Developer Should Know

21 Popular JavaScript Libraries Every Web Developer Should Know:

 Below are 21 libraries/frameworks all JavaScript developers consider for their project.

  • ANGULAR JS

Angular is one of the oldest JavaScript libraries till date. Wait, Angular is actually a Framework, not a Library. It allows you create single-paged, client-side web applications. Angular is written in TypeScript and backed by Google.
Some of the popular companies who use Angular are Google (obviously), PayPal and iTunes.

  • VUE JS

Very similar to React, Vue is a front-end framework used to create single-paged applications with the popular component-based architecture. The upside with using Vue is that you write smaller amount to code compared to other UI libraries. Vue JS is growing stronger by the day, and is getting adopted at a quick rate.

  • UNDERSCORE JS

Underscore is a lower level JavaScript library. Lower level in that it’s very close to vanilla JavaScript. All it does is provide you with some helpers and tools to create web applications faster.

  • BABYLON JS

I have a confession to make; I really love the name of this particular library.
For the game developers, this name might not be a new one. Babylon is a full fledged 3D video game engine for creating complex and web-based 3D Video games.

  • REACT

This is probably the one you were all waiting for. React is one of the most popular JavaScript library in existence. You see those similar and cool looking buttons, or perhaps those nice looking navigation bars, or some cool modals you just can’t stop marvelling at?
Chances are they were all made with React. React is a component-based UI library which allows you create reusable UI elements (components) for your website. It is used by many companies, including Facebook, of course.

For those of you looking to learn React, HTML to React is a brilliant course to go from knowing just HTML to knowing React.

  • EMBER

Ember is a powerful JavaScript framework which helps developer to create websites without having to worry about the nitty-gritty of the process.
It includes everything you need to create rich UIs and combine them to form a powerful and highly scalable website.

  • BACKBONE JS

Another cool name!
Backbone.js is a very simple and straightforward JavaScript library and framework. Its biggest distinguishing feature is the fact that it can fit within a single JavaScript file. Backbone is a great option for those looking to build simple websites.

  • CLIPBOARD JS

As its name already implies, Clipboard allows you copy data from your site right off the bat! No need to install any additional dependency.

  • BABEL

Some of us may be already be aware of the story of the tower of Babel in the bible. Creating a language division amongst the builders to cut of communication and create discordance.
Well this tool is the solution to that problem, in the context of JavaScript. When creating code, browser compatibility is open an issue to consider. Older web browsers tend to be dropped in favour of newer ones, but not all users update. There are still machines and devices out there that are running old versions of web browsers.
Babel is a JavaScript compiler which compiles your JS code to ES5 compliant nature. This means your code can run on new browsers such as Edge as well as older ones, such as IE 9.

  • SVELTE

Svelte is a complete new approach to building user interfaces. While traditional frameworks like React and Vue are browser based, Svelte shifts that work into a compile step that happens when you build your app.

  • LETTERING JS

Lettering is an interesting JavaScript library for texts. You can style and layout individual texts on your page, including implementing some cool transitions and animations. Lettering JS is a jQuery plug-in. Hence, it requires jQuery to work.

  • CHARTIST JS

Ah, here is something for the data analysts!
Chartist is a nice JavaScript library for creating simple, responsive and customizable charts for your website. Chartist uses SVG to render them; hence, your charts can also obey custom CSS rules.

  • DROPZONE JS

Dropzone allows you implement “drag and drop” features on your website. It is also highly customizable with custom code. It’s lightweight, doesn’t depend on any other library (like jQuery).

  • THREE JS

Aha! Something to make some cool, eye-catching stuff.
Three js is an immensely popular JavaScript 3D library for creating visual effects on your website. It is a great option for those looking to create 3D visualizations without the need for heavy-duty game engines.

  • jQUERY

jQuery is one of the oldest yet most popular JavaScript libraries still in existence. You’ve probably already heard of the DOM, which stands for Document Object Model. jQuery is perfect and quite reputed for manipulating the DOM. You can also dothings like HTML events, animations and effects, CSS manipulation, and AJAX calls.

  • LODASH

When you think of this library, you think of utilities. Lodash is an immensely useful library which contains and provides utility functions which you call into your code to perform a specific task. Saving your time you would have wasted in writing it yourself.

  • PIXI JS

Named after the popular movie animation studio Pixar, Pixi is an open source 2D engine used to create beautify, eye-catching animations on your website. Pixi uses WebGL, and uses HTML canvas if the former is not supported.
PixiJS is made of multiple consumable components that can be installed in your project with NPM/Yarn

  • D3 JS

D3.js is a JavaScript library for manipulating documents based on the nature of data received.
It stands for “Data Driven Documents”, which kind of explains its task. The library uses pre-built functions to select DOM elements, create SVG objects, style them and add transitions and other effects. These objects can also be styled using pure CSS.

  • SOCKET.IO

You should know that by default, the connection between the browser and web server is closed once the server responds with data. So how do you keep the connection open so data can seamlessly flow bi-directionally without having to make new requests in the process?
Socket.io, based on web sockets, is a JavaScript libabry which enables event-based two-way communication between the browser and the web server. It utilizes a node.js server.
https://socket.io/

  • MATH JAX

Ah, good old maths.
As its name suggests, MathJAX simply allows you to include mathematics in your pages. This includes special math notations and symbols. MathJax automatically formats the mathematical symbols and equations that you enter in HTML and problem components using LaTeX notation into beautiful math. A MathJax equation can appear with other text in the paragraph (inline) or on its own dedicated line (block).

  • MODERNIZR

Modernizr is a libary of tests. Features like CSS transform, web sockets, CSS transitions and animations can be tested on the browser using special properties from Modernizr.
There are over 260 features which can be tested using this utility.

Python-Powered Web Server

Python-Powered Web Server:

Setting Up Your Dev Environment

Because this tutorial is for JavaScript coders, we’ll be working in VS Code instead of PyCharm. I’m working in Ubuntu 18.04, so ideally this is for other Linux users, but I will include alternative commands for Mac and Windows where possible.

The first thing you’ll need to do is fire up VS Code. I created a directory named “python” to work in. Install the Python extension for VS Code.

Next you’ll need a Python package manager and interpreter. Ubuntu users can install Pip with the commands sudo apt update followed by sudo apt install python3-pip in the terminal. Enter pip3 --version to confirm you did it right. You’ll get back something like this: pip 9.0.1 from /usr/lib/python3/dist-packages (python 3.6)Windows and Mac users can follow the respective links for instructions on installing package managers.

Linux users should have Python3 as a default Python interpreter. If you’re not sure if you have it, or if you’d like to change it, you can press ctrl+shft+P and type “Python: Select Interpreter” into the search box. Click the one you want. I’m using Python 3.6.9. If you have an interpreter set up, you should have a “.vscode” folder in your project folder with a “settings.json” file that includes a “python.pythonPath” key whose value is the file path to your interpreter.

Testing Python

In your root directory, create a folder called “test.py” (touch test.py for Linux users), and enter the following two lines:

msg = "Its Alive"
print(msg)

Save the file, and run it by pressing the play button at the top-right of your VS Code window. You’ve probably never used this thing if you’re used to writing JavaScript, so here’s a picture with the button highlighted.


Pressing it should have the same effect as running node [somefile].js. If you see the text “Its Alive” in your terminal, you are officially coding in Python.

Virtual Environment

Before we install Django, we’re going to create a virtual envrironment. I’m running Linux, so I’ll run the following two commands in my terminal:

sudo apt-get install python3-venv
python3 -m venv env

Here are the MacOS and Windows alternatives:

python3 -m venv env (for Mac)
python -m venv env (for Windows)

Say yes to all the prompts. Your project folder should now contain an “env” directory with some folders in it (“bin”, “include”, “lib”, ect). It should sort of look like your standard JavaScript / Node project. You’re going to redirect your Python interpreter to this folder. So once again press ctrl+shft+P and search for “Python: Select Interpreter”. You should see a new option with (‘env’) at the end. Click it, and it should update your “settings.json” file to direct to the new file path (“env/bin/python” on my end).

Press ctr+shift+P again, and this time type “Terminal: Create New Integrated Terminal” into the search bar. Click the result, and your terminal window should display a command line starting with “(env)”. This is your integrated terminal window, where we’ll install Django. If at any point you close your project and come back, your terminal will not default to the integrated terminal window. The following commands will bring you back into your integrated terminal window:

source env/bin/activate (Linux or Mac)
env\Scripts\Activate.ps1 (Windows)

Django

In your integrated terminal window, enter the following two commands:

python -m pip install --upgrade pip
python -m pip install django

If you’re using Windows, and these commands don’t work, try troubleshooting with this link.

When the installation is complete, you’re ready to make a Django app. You’ll start your project by running the following command in your integrated terminal:

django-admin startproject web_project .

This will create a new folder called web_project in your parent directory as well as a few utility files. Next, create your database and start your server:

python manage.py migrate
python manage.py runserver

Your terminal will give you a link to http://127.0.0.1:8000/ and you’ll see the following default message on your page:

Next step is to replace the default success screen with some personalized content, which we’ll do with the startapp command:

python manage.py startapp myfirstpython

This will create a “myfirstpython” folder with a “views.py” file. Replace the contents of “views.py” with the following code and save:

from django.http import HttpResponse

def home(request):
    return HttpResponse("Boilerplate Django App")

Now, in your “myfirstpython” folder, create a file called ursl.py with the following code:

from django.urls import path
from hello import views

urlpatterns = [
    path("", views.home, name="home"),
]

Your web_project folder also contains a urls.py file. Replace its code with this:

from django.contrib import admin
from django.urls import include, path

urlpatterns = [
    path("", include("myfirstpython.urls")),
    path('admin/', admin.site.urls)
]

Save and re-run the command to start your server in your integrated terminal:

python manage.py runserver

Following the link to http://127.0.0.1:8000/ should bring up a plain white page with the text “Boilerplate Django App.” And there you have it. Your first webpage without any JavaScript. It’s not much, but if you study Python, and follow some of the links below, you can make a fully interactive page with Django. Feel free to fork this boilerplate and run with it.

Best Selenium Python Frameworks for Test automation in 2021

Best Selenium Python Frameworks for Test automation in 2021:

Introduction

As per a recent Developer Survey by Stack Overflow, Python is the third most sought-after programming language among developers. It is the most accessible and simplified programming language and provides an extensive support system for test automation frameworks. With more and more implementation of Artificial Intelligence, Python has become a popular choice. Many liked Selenium Python frameworks for test automation are employed for cross-browser and automation browser testingPython testing frameworks have seen a surge in their demand recently, making it imperative to choose the best Selenium test automation framework that suits your requirements.

Why Python for Test Automation? It is because of its simplicity, intuitiveness, and readability. It is less messy, beginner-friendly, and a highly competitive programming language. It provides a fast learning curve to write scripts in lesser time. Python is easy to understand, so the manual testers feel confident while shifting towards automation.

Let us discuss how to use Selenium Python Frameworks for fulfilling your Selenium Test Automation needs

Apart from PyUnit that is a default Python Testing framework in 2021, there are a myriad of Selenium Python Frameworks available in the market to choose from, below are a few of the top frameworks:

1. PyTest Framework

It is one of the most venerable Python Selenium frameworks for scalable test automation. Being open-source, it is easily accessible by the Development teams, QA teams, and open learning groups for open source projects. It supports Unit, Functional, and API Testing. It is compatible with Python 3.5 and PyPy3 Python versions and is easily installable via Python Package Manager (pip) command. Python Testing Frameworks start with traditional test_ (or end with _test) nomenclature but, PyTest doesn’t carry such restrictions because of its built-in auto-discovery features that look for inherent test modules and functions. Also, with the help of the assert writing feature, there is no need to remember self.assert* names to fetch failing assert statement data. We can not ignore the fact that there are compatibility issues with PyTest, which means you can write test cases with convenience but can’t use them with other testing frameworks. Creating customized HTML reports with Robot Framework is quite tricky. Also, PyTest does not support parallel testing entirely.

Requirements:

Learning and using Pytest is effortless, making it easy to get started with just a little knowledge of any Python Selenium Framework.

-You would also need a Python integrated development environment along with Python Packaging Manager for PyTest installation.

2. Robot Framework

Robot Framework is a popular open-source Python Selenium Frameworks trusted by Python Developers for implementing acceptance testing. Acceptance is also used for Test-Driven Development (TDD) and Robotic Process Automation (RPA) within the automated testing strategy. Robot Framework is Python-based but can also run on .net-basedIronPython and Java-basedJython.Robot Framework uses Keyword style to write test cases. It provides easily understandable HTML reports and screenshots. The Robot framework has a rich API ecosystem that allows smooth integration with third-party tools. It is very well-documented. It follows a keyword-based, data-driven, and Behaviour driven approach for the maintenance of test readability.Itis compatible with Windows, macOS, and Linux operating systems and with all applications, be it mobile, web, or desktop.

Requirement:

-The capacities ofRobot Framework can be optimally utilized using Python version 2.7.14 or higher.
-Python Package Manager Command (pip) is used for its installation.
-A development framework like PyCharm Community Edition should be must to download to use the Robot framework.

3. Behave Framework

Behave is a widely used Python Selenium Framework allowing software teams to perform BDD Testing with the latest version as 1.2.7.dev1. Behavior Driven Development, agile software Development Methodology enables developers, testers, and businesses to have a symbiotic collaboration. It functions similarly to SpecFlow andCucumber Framework for automation testing. It uses Gherkin language to make business understandable test case scenarios encouraging Business-Driven Development (BDD). Behave is based on a fundamentally different BDD Framework, making it different from all other Python Selenium Framework. Behave carries a few disadvantages like, it is not supported well in PyCharm environment and can only be used in Black-box testing. The primary requirement for automated browser testing is the need for parallel testing. But it is not supported by Behave because it does not carry any built-in support for parallel test execution.

Requirement:

-It requires Python version 2.7.14 or above.

-Basic knowledge of any of the Behavior Driven Development tools

-Python Package Manager Command (pip) is needed for its installation

-The most preferred development environment like PyCharm or any other IDE is also required to work with Behave.

4.PyUnit (or UnitTest) Framework

UnitTest is another name for PyUnit, which is considered a standard Python Selenium Framework for test automation. PyUnit is a Unit testing framework for Python inspired by JUnit and works similar to other unit testing frameworks. It is the first Python automated Unit Testing Framework- a part of the Python Testing Library. With easy installation and Configuration, UnitTest Python Unit Testing Framework is used by all developers who are getting started with Selenium Test Automation. The test cases follow a usual start with test_ (or end with _test) nomenclature. UnitTest reporting utilizes UnitTest-XML-reporting and generates XML reports like in the case of Selenium Testing with JUnit. The traditional CamelCase naming method derived from JUnit persists even now, making the test code unclear sometimes. Also, there is an increasing need for boilerplate code.

Requirements:

Since UnitTest comes by default with Python, Python Selenium Framework does not require any additional package or module installation.

-Basic knowledge of Python Framework is sufficient to get started with PyUnit.

-In case you are dealing with additional modules, Python Package Manager Command (pip) and IDE would be required.

5.Nose2 Framework

Nose2 is another Selenium Python Framework for dock tests and unit tests and also a successor of Nose. Since it is based on Unittest, so also sometimes known as an extension of UnitTest and supports PyUnit by providing plugins for test execution, test case auto-discovery feature, and allows assembling and collection of documents. Nose2 is a Domain-Specific Language (DSL) for writing functional tests. Its inbuilt plugin ecosystem makes testing simple and faster. It also provides support to decorators, fixtures, classes, parameterized testing modules, complex initialization, and automatic discovery of test cases. Its documentation is limited.

Requirements:

-Nose2 functions with the Unittest module that comes along with the Python Library

-It needs to be installed with the help of Python Package Manager Command (pip).

6. Testify Framework

Python’s Unittest and Nose Python Selenium framework were replaced with Testify, which is more Pythonic in nature. It is an advanced version of Unittest. Testify was created after Unittest so, the tests framed for Unittest demand bare minimum test modifications to work well with Testify. It is mainly used for performing automated Unit, System, and Integration testing. Testify is a successful example of Java Implementation of semantic testing. Testify’s expansive plugin ecosystem contains important properties around reporting and publishing. Other features similar to Nose2 Framework are automatic test discovery, class level set-up, and simple syntax to fixture methods that need to be run once for the whole set of test methods. However, it does not provide extensive documentation, and the scope for performing parallel testing makes it quite a challenge.

Requirements:

-Testify is based on the existing Unittest framework, which provides a gradual learning curve

-It only requires the Python Package Manager for installation.

7. Lettuce Framework

Lettuce is a Behavior Driven Development Testing Framework based on Cucumber and Python. This Python Selenium framework was designed to make testing simple and interesting to its users. It is an open-source framework and is usually hosted on GitHub. Its latest version 0.2.23 is called Kryptonite. It uses Gherkin languageto create tests, test scenarios, and feature files using user-friendly keywords. It is the same as Behave Black box testing but can be used for more types of testing. Its execution requires on-time communication between all project stakeholders like developers, testers, marketing managers, and project managers.

Requirements:

-Lettuce needs Python version 2.7.14 or above,

-A prior experience with any BDD Framework

-Python Package Manager (pip) for installation

Conclusion

Selenium is at its best when developers perform automation testing and save time by pushing the changes quickly. The biggest challenge that Selenium has to deal with, even after being known for having a robust testing suite, is the ever-changing nature of the front-end technologies. We focused on various popular Selenium Python Frameworks for testing available today. Each one of them has its respective strengths and weaknesses, however, the choice of the framework you use must be made depending upon the team’s language proficiency and its relevance in the type of project requirements. There are some BDD tools like Behave and Lettuce that are used in case the team comprises non-technical members. PyTest is a great choice over the default Python Selenium framework to leverage the development of complex functional tests. If you are just at the beginning stage and want to know how to use selenium python for testing, Robot Framework should be a great starter.

Decorator Functions in Python.

Decorator Functions in Python.:

 

A decorator function allows you to add or modify an existing function without actually modifying it’s structure.

This is a very basic explanation of a decorator function.

But the question here is why should we use a decorator function when we can just change a function as required?

Well, it’s not always you have one single function that you might want to modify. Suppose you have a bunch of functions in your project where you want to make a specific change to all the function as a part of your requirement.

Now it would be very tedious to find and modify each and every function and also test each one of them to make sure it does not break your application.

For that you have decorator function using which you can modify it without actually altering any of the code inside the function. Decorator function can have many use cases but is typically used when you want to make minor changes to your existing set of functions.

Let’s have a look at the simple example:

def deco_func(val):
    def wrapper():
        print("Trigger")
        print(val)
        print("Kill")
        print("------------------------------")
    return wrapper

holder = deco_func("Hello Python")
print(holder)
holder()

Output:

<function deco_func..wrapper at 0x7efcdc4e8550>
Trigger
Hello Python
Kill
------------------------------

The above example is possible in python because the functions here are treated as first class objects, which means that functions can be passed as or used as parameters/arguments.

Here’s some quick pointers to keeps in mind:

  • A function is an instance of the Object type.
  • A function can be stored in a variable.
  • A function can be passed as a parameter.
  • A function can return a function.

Now, let’s make some minor changes in the above code:

def deco_func(func):
    def wrapper():
        print("Trigger")
        func()
        print("Kill")
        print("------------------------------")
    return wrapper

def func1():
    print("This is Function 1")

def func2():
    print("This is Function 2")

def func3():
    print("This is Function 3")

func1 = deco_func(func1)
func2 = deco_func(func2)
func3 = deco_func(func3)
print(func1)
func1()
func2()
func3()

Output:

<function deco_func..wrapper at 0x7f6960526820>
Trigger
This is Function 1
Kill
------------------------------
Trigger
This is Function 2
Kill
-----------------------------------
Trigger
This is Function 3
Kill
-----------------------------------

In the above code we have updated the deco_func and now it accepts a function as an argument.
We have also created three functions that just print a statement.
Now, the line
func1 = deco_func(func1)
allows us to store the deco_func which accepts a parameter func1, all that in a variable func1. Hence, we can now call func1() to get the desired results.
By seeing the above piece of code, you can now figure out a bit, how decorator function works behind the scenes.

So, whenever you are creating a decorator function you have to create this wrapper function/functionality.
The outer function takes the function itself as an argument and the inner wrapper function calls the actual function upon which you are making the modifications.

Below is an example of the above code as a decorator function syntax in Python:

def deco_func(func):
    def wrapper():
        print("Trigger")
        func()
        print("Kill")
        print("------------------------------")
    return wrapper
@deco_func
def func1():
    print("This is Function 1")
@deco_func    
def func2():
    print("This is Function 2")
@deco_func    
def func3():
    print("This is Function 3")

func1()
func2()
func3()

Now, these are sort of dumb functions that just print a statement.
What happens when one of the functions requires one or more parameters to be passed and some doesn’t. Or, some functions return a value and some doesn’t??

Below is an example when one or more functions requires and arguments/parameters to be passed or one or more functions happen to return some value back when they are called. The whole point of decorator functions is to be able to use in any functions use-case, hence for that we use the unpack or splat operator i.e. * args and ** kwargs:

def deco_func(func):
    def wrapper(*args, **kwargs):
        print("Trigger")
        res = func(*args, **kwargs)
        print("Kill")
        print("------------------------------")
        return res
    return wrapper
@deco_func
def func1(val):
    print("This is Function 1")
    print("Function 1 value: ", val)
@deco_func    
def func2(val1, val2):
    print("This is Function 2")
    return val1 + val2
@deco_func    
def func3():
    print("This is Function 3")

func1(20)
result2 = func2(45, 40)
func3()
print("Function 2 sum value: ", result2)

Output:

Trigger
This is Function 1
Function 1 value:  20
Kill
-----------------------------------
Trigger
This is Function 2
Kill
-----------------------------------
Trigger
This is Function 3
Kill
-----------------------------------
Function 2 sum value:  85

As you can see that the splat operator helps the decorator function to accept none or any number of parameters and the res variable stores the returned value of the decorated function to serve it’s purpose.

So, That’s all about decorator function. I know it’s a bit too much to take at a single reading, but I suggest open your python console or jupyter notebook and follow each line of the code snippets to understand the functionality and it will be a piece of cake for you!

Understanding TypeScript Decorators

Understanding TypeScript Decorators:

 

Decorators are used to modify classes and its members (methods, properties).

The question may be, why do we need decorators to change those things? Why not directly change in the declarations?

Directly changing is not scalable. If you need the same changes in 100 classes, you have to write it 100 times. Using decorators, you write it once and apply it as many times as you want.

Decorators give you a central point of change which easier to work with. Frameworks like NestJSAngular use decorators extensively.

In TypeScript, you can decorate the following things:

  • class
  • method
  • property
  • accessor
  • parameter

Decorators are a TypeScript feature and are not officially included in JavaScript yet. However, they are likely to be added in the future (Currently in stage 2).

Class decorator

// The following decorator makes any class more Funky
function makeFunky(target: Function) {
    return class extends target {
        constructor() {
            super()
        }
        funkIt() {
            console.log("Get The Funk Outta My Face")
            }
        }
    }
}

@makeFunky
class Car {
    wheels = 4
    state = 'pause'
    drive() {
        this.state = 'running'
    }
}

const car = new Car()
car.funkIt()
// logs: Get The Funk Outta My Face

Decorators are just functions, makeFunky is the decorator above. makeFunky gets the class Car it’s applied to as a parameter. It returns a new class which is just a modified version of the original class.

Decorators are called when the class is declared—not when an object is instantiated.

Method decorator

Decorators applied to a method gets the following parameters

  • target : for static methods, target is the constructor function of the class. For an instance method, target is the prototype of the class.
  • propertyKey : The name of the method.
  • descriptor : The Property Descriptor for the method
function log(target: Object, propertyKey: string, descriptor: PropertyDescriptor) {
    const originalMethod = descriptor.value
    descriptor.value = function () {
        console.log('arguments are ', arguments)
        const result = originalMethod.apply(this, arguments)
        console.log(`result is ${result}`)
        return result
    }
    return descript
}

class Calculator {
    @log
    add(x: number, y: number): number {
        return x + y
    }
}

const calc = new Calculator()
calc.add(10, 20)

/*
[LOG]: "arguments are ", {
"0": 10,
"1": 20
} [LOG]: "result is 30" */

Property decorator

Similar to method decorator. Gets the same parameters targetpropertyKey, and descriptor as the method decorators. Its return value is ignored.

function logMutation(target: any, key: string ) {
    var _val = target[key]
    Object.defineProperty(target, key, {
        set: function(newVal) {
            console.log('new value is ' + newVal)
            _val = newVal
        },
        get: function() {
                return _val
            }
        })
}

class Person {
    @logMutation
    public age: number

    constructor(age: number) {
        this.age = age
    }
}

const jack = new Person(20)
jack.age = 40

/*
[LOG]: "new value is 20" [LOG]: "new value is 40" */

Accessor and parameter decorators

Accessor decorators are same as method decorators, but they are applied to either the getter or setter method of a single member.

Parameter decorators are applied on, you got it, parameters.

Decorator Factory

A common pattern in decorator usage is calling a function that returns a decorator. Here’s the previously mentioned method decorator log , returned by invoking the function logger

function logger(functionName: string) {
    function log(target: Object, propertyKey: string, descriptor: PropertyDescriptor) {
        const originalMethod = descriptor.value
        descriptor.value = function () {
            console.log('method name: ' + functionName)
            console.log('arguments are ', arguments)
            const result = originalMethod.apply(this, arguments)
            console.log(`result is ${result}`)
            return result
        }
    }
    return log
}

class Calculator {
    @logger('add')
    add(x: number, y: number): number {
        return x + y
    }
}

const calc = new Calculator()
calc.add(10, 20)

/*
[LOG]: "method name: add" [LOG]: "arguments are ", {
"0": 10,
"1": 20
} [LOG]: "result is 30" */

Decorator in the wild

Some use cases of decorators as being utilized by popular libraries/frameworks.

  • NestJS uses the class decorator @Controller('pathName') to define a class as a controller. Decorators associate classes with required metadata and enable Nest to create a routing map (tie requests to the corresponding controllers). It also uses decorators to define modules, injectable instances for its dependency injection system.
  • TypeORM uses decorators to define a class as an entity @Entity(), tagging properties as columns @Column(), auto-incremented ID etc.
  • The NPM package class-validator is used for validating properties in an object (used in validations such as income data, arguments of a function). It has decorators like @IsInt() @Min(5) @Max(25) to set restrictions on a particular field.

Top 20 cloud computing skills to boost your career in 2021

Top 20 cloud computing skills to boost your career in 2021:

 

As cloud adoption increases, so too does the need for IT experts with cloud computing skills. Here are 20 key skills to help you on your journey.

Cloud computing skills are in higher demand now than ever.

Larger businesses have been making a move to the cloud for several years, gradually reducing their levels of investment in on-premises data centers and servers. But the trend toward cloud adoption has seen a significant uptick over the last year, as the COVID-19 pandemic forces organizations to enable and support more remote, distributed workforces.

This called for the deployment of cloud-enabled video conferencing tools, including Zoom and Microsoft Teams. There was spike in demand for employee productivity and collaboration products, such as Google Docs. And streaming services, such as Netflix and Amazon Prime Video, gained in popularity as extended lockdowns and stay-at-home orders were in effect.

What is cloud computing?

Cloud computing enables people to access software applications, data storage and other services over the internet instead of through traditional physical servers in a back office.

The cloud computing model enables users of internet-based computing services to be charged for what they consume on a pay-per-use basis. This is often referred to as a consumption-based pricing model and is a departure from more traditional subscription-based pricing models.

There are three main types of cloud services:

  1. Software as a service (SaaS). These are on-demand hosted services that provide access to business applications.
  2. Platform as a service (PaaS). These are web-based services and deployment of applications in the cloud.
  3. Infrastructure as a service (IaaS). These are virtualized computing resources over the internet and often offer storage.

For many businesses, the attraction of cloud services lies in the fact that they don’t need to buy and maintain their own physical technology products, software, storage and infrastructure.

The cloud computing world is currently dominated by a handful of large, public cloud service providers (CSPs) and their products. These include AWS, Google Cloud Platform (GCP) and Microsoft Azure. These vendors can deliver the same service to hundreds of thousands – or even millions – of customers of various sizes and across different industries at an attractive price point.

Top cloud providers graphic

Cloud computing jobs beckon

Cloud computing is firmly entrenched in all aspects of business and home lives, and it’s here to stay. That means increasing numbers of businesses are actively seeking out qualified and experienced cloud experts across several domains, including engineering, database management, programming, development, security and analytics. LinkedIn rates cloud computing as the most sought-after tech skill, alongside artificial intelligence and big data. This presents an opportunity to those who are willing to rise to the challenge of mastering the basic and more advanced cloud computing skills.

Here are the top cloud computing skills you’ll want to obtain in 2021.

Key general cloud computing skills

1. Cloud service platform expertise

Gaining a thorough understanding of the CSP marketplace is a good starting point. Familiarize yourself with AWS, Azure and GCP. Other companies with cloud platforms include IBM, Dell, Cisco Systems, Oracle and OpenStack.

It is essential to differentiate between providers in terms of which may be most appropriate to house different applications or on which to run different types of workloads. You will need to be able to point out the pros and cons of each and select the best option to meet a specific need.

Each of the leading cloud platforms has its own strengths. AWS takes the lead in infrastructure. Microsoft excels in software. Google offers easy integration with other vendor products. IBM has honed artificial intelligence capability. Cisco Systems is a frontrunner in networks. And OpenStack is dominant in the software development market.

2. Programming languages

Knowledge of mainstream programming languages and the ability to write code to build, deploy and manage applications quickly are core capabilities for cloud architects, engineers and administrators. Certain programming languages, such as Java, JavaScript and Python, are best suited for cloud-based software. Database programming requires familiarity with SQL, NoSQL and Linux.

Read more here about the top six programming languages.

3. Application programming interfaces (APIs)

APIs are cloud-based software applications that interface with a number of networking and system components. To link and integrate different workloads to the cloud requires knowledge in the use of APIs. As a cloud professional, you will need to be adept at coding these APIs and the links used to integrate workloads into the cloud.

4. Database management

Today, businesses’ databases are quickly moving to and running in cloud-based environments. This is an evolution from the days when databases were housed in physical data centers and managed in local geographies. Cloud databases can reside anywhere within a cloud infrastructure. If you have your sights set on becoming a cloud engineer, you will need to have skills that extend beyond what is required to manage databases that run in traditional on-premises data centers.

5. Network management

Knowledge of the basics of networking and the ability to integrate cloud services with the underpinned networks are essential skills. That’s because, in the world of cloud computing, centralized computing resources are shared among a number of users. As a result, more and more core network management tasks and functions are being pushed into the cloud, which reduces the number of customer devices required to manage the environment.

If you’re looking to become a cloud engineer, your duties will include ensuring that the network is stable and responsive to user demands by implementing automatic adjustment procedures. This calls for an understanding of the mechanisms of virtual networks.

6. Development and operations (DevOps)

In today’s cloud environments, the days when developers and operations support personnel worked in their own silos are long gone. DevOps is the practice of harmonizing and integrating development and operations activities throughout the entire service lifecycle, including design, the development process and production support. This approach significantly reduces time to market for applications and eliminates unnecessary bottlenecks.

7. Machine learning and AI

Any aspiring cloud computing professional should gain a firm grasp of the fundamentals of artificial intelligence and machine learning. In cloud environments, much activity takes place without a high degree of human interaction. Machine learning and artificial intelligence skills are among the scarcest and most sought-after technology skills out there today.

Take this quiz to see what you know about machine learning and AI.

8. Cloud security

In cloud computing environments, both the storage and retrieval of data are performed beyond the traditional corporate boundaries and firewall. The cloud is particularly vulnerable to attacks and compromises, simply because the threat surface is so immense. This calls for a focus on security.

The negative effect of the loss or breach of personal customer data or proprietary company intellectual property can be devastating for businesses from both a reputational and financial perspective. Today, the demand for cybersecurity talent well outpaces its supply, and the ongoing rise in cloud computing technologies means that this trend is only set to continue.

9. Hybrid cloud

While the cloud has many benefits, it is not suitable for every part of a business’s IT infrastructure, applications and workloads. For this reason, the notion of adopting a hybrid cloud approach has gained popularity in recent years.

In a hybrid cloud model, certain elements are retained on premises or in a dedicated private cloud, while less sensitive or more modern applications are migrated to a public cloud. To make the correct decisions about what belongs where, cloud professionals will need an understanding of how each cloud model works and how to unify them into a hybrid arrangement.

10. Storage

Data lies at the heart of cloud computing, so it is essential to understand how and where to store it. Depending on a business’s needs and the type and volume of its data, it may select one or more of the following types of storage:

  • personal cloud storage
  • public cloud storage
  • private cloud storage
  • hybrid cloud storage

The benefits of cloud storage include the following:

  • accessibility
  • reliability
  • fast deployment
  • data backup and recovery
  • lower cost

In-depth understanding of how each type of cloud storage works is a valuable skill for cloud computing professionals.

11. Containers

Containers provide a packaging mechanism in which applications may be abstracted from the environments in which they are running. This decoupling process enables businesses to deploy container-based applications swiftly and consistently. Knowledge of today’s most popular container technologies, such as Docker and Kubernetes, will increase your likelihood of securing employment in a cloud computing role.

12. Data and application migration and deployment

Moving software applications from a data center into a cloud environment is more complex than copying files from one server to another. That’s because applications include elements such as code and files that execute commands and perform tasks, so a thorough assessment needs to be undertaken before any cloud migration is carried out. The best cloud professionals will treat each application on its own merits and be prepared to work with business stakeholders to chart the best course forward.

13. Automation

Automation is one of the most significant benefits of cloud services. If applications can be programmed to make their own, correct decisions without human intervention, it can increase efficiency. Of course, cloud professionals have a role to play in facilitating this kind of automation. Specifically, they need to be well versed in the mechanics of a business’s cloud architecture and the different components that interact with or depend on one other.

Common cloud automation tasks graphic

14. Cloud orchestration

Cloud orchestration is much like cloud automation; however, it involves the automation and coordination of multiple tasks instead of just one.

15. Linux

Linux is an open source OS that offers features such as easy customization and security. The demand for cloud professionals who can design, build, deploy, maintain and administer Linux-based servers is on the rise.

16. Performance testing

Testing the performance of cloud environments enables you to gauge how effectively they are operating. It will also uncover areas for potential iterative improvement.

17. Metrics and analytics

Expertise in metrics and analytics – and understanding which metrics should be applied to specific cloud services – will stand you in good stead. That’s because these skills enable you to demonstrate the ROI of a business’s cloud technology.

18. Cost and workload management

The ability to determine and monitor cost and workload estimation are valued skills. For instance, they will enable you to pinpoint if and where certain set data limits are being exceeded, which can lead to a business incurring unforeseen costs. It also enables the identification and elimination of any features that are not being used.

19. Change management

Cloud environments are extremely fluid. This means that the best cloud computing experts are comfortable functioning in an atmosphere that is continually in flux and can stay on top of constant changes to the underlying infrastructure, including databases, servers and network connections.

20. Cloud partnering

In cloud computing environments, several IT functions may be outsourced. It is not uncommon for businesses to engage with external consultants and contractors to benefit from their specialized skills. These cloud partners can bring invaluable experience and new insights into a project team. Prospective employers will look for candidates who are at ease with these kinds of arrangements.

How do you gain these key cloud computing skills?

There is no shortage of available learning resources to help you build and continually augment your cloud computing capabilities. These include both formal training at colleges, as well as free and paid online resources. Many businesses also offer on-the-job training opportunities.

Certifications that are recognized globally include the following:

  • AWS Certification
  • IBM Certified Solution Architect
  • Microsoft Azure certifications
  • Google Cloud Associate and Professional certifications
  • (ISC)2 Certified Cloud Security Professional
