Discussion About Babel.js?

What is Babel?

Babel is a JavaScript transpiler.Essentially Babel takes the ES2015 JavaScript code and compiles it into ES5 code. This opens up all the ECMAScript 6 features to us when we code our projects.

The compiler can be broken down into 3 parts:

  1. The parser: babylon (moved to a separate repo and versioned independently)
  2. The transformer[s]: All the plugins/presets.These all use babel-traverse to traverse through the AST
  3. The generator: babel-generator
Babel has support for the latest version of JavaScript through syntax transformers. These plugins allow you to use new syntax, right now without waiting for browser support.
 

Node NPM InstalInstallation:

npm install --save-dev babel-preset-env​

What is Sinon.Js?

“Standalone test spies, stubs and mocks for JavaScript. No dependencies, works with any unit testing framework.” Sinon.js is a really helpful library when you want to unit test your code. It supports spies, stubs, and mocks.

Sinon provides spies, stubs, and mocks. They’re all useful as fakes in tests. They come with essential differences for what they’re helpful in doing and how they work.

Test stubs are functions (spies) with pre-programmed behavior.

They support the full test spy API in addition to methods which can be used to alter the stub’s behavior.

As spies, stubs can be either anonymous or wrap existing functions. When wrapping an existing function with a stub, the original function is not called.

Example :

var stub = sinon.stub();

NPM Installation

npm install sinon

What is WebPack.Js?

Webpack is a module bundler for modern JavaScript applications. It is incredibly configurable, but to get started you only need to understand Four Core Concepts: entry, output, loaders, and plugins.

Webpack constructs two separate dependency graphs and emits two bundle files, one called app.js containing only the application code and another called vendor.js with all the vendor dependencies.

Webpack is fed via a configuration object. It is passed in one of two ways depending on how you are using webpack: through the terminal or via Node.js. 

Webpack enables use of loaders to preprocess files. This allows you to bundle any static resource way beyond JavaScript. You can easily write your own loaders using Node.js.

It allows you to split your codebase into multiple chunks. Chunks are loaded asynchronously at runtime. This reduces the initial loading time

NPM Module for install

npm install webpack -g

What is Video.Js?

Video.js is an open source library for working with video on the web, also known as an HTML video player
VideoJS is an HTML5 Video Player with 3 core parts: 

  1. An embed code (Video for Everybody), 
  2. A Javascript library (video.js), 
  3. A pure HTML/CSS skin (video-js.css). 

Using Video for Everybody as the embed code means you know it's compatible with many devices (including ones without javascript).

The core codebase uses a few modern features of Javascript (ES5), so if you'd like to support IE8 you'll need to include an ES5 shim. To make things easier, we created a single file you can include for IE8 support. 

Npm Install Code

npm install --save-dev video.js

Bower Install Code

bower install video.js

What is System.Js?

The JavaScript Package Manager (aka jspm) is a package manager that works on top of the SystemJS universal module loader. ... SystemJS is a module loader that can import modules at run time in any of the popular formats used today (CommonJS, UMD, AMD, ES6)

Features:

  • Loads any module format when running the ~15KB development build.
  • Loads ES modules compiled into the System.register module format for production with exact circular reference and binding support
  • Supports RequireJS-style map, paths, and bundles configuration.

Built with the ES Module Loader project, which is based on principles and APIs from the WhatWG Loader specification, modules in HTML and NodeJS.

Supports IE9+ provided a promises polyfill is available in the environment.

System.js however is a pretty good replacement for require.js. The config is robust, the bundling API is reasonable, and if you have dynamic loading scenarios, especially where you don't know the resources at bundling time, it's really a good client loader.

Node Command :

npm install systemjs

What is Phantom.Js?

PhantomJS is a scripted, headless browser used for automating web page interaction. PhantomJS provides a JavaScript API enabling automated navigation, screenshots, user behavior and assertions making it a common tool used to run browser-based unit tests in a headless system like a continuous integration environment.

PhantomJS is a headless WebKit scriptable with a JavaScript API. It has fast and native support for various web standards: DOM handling, CSS selector, JSON, Canvas, and SVG.

The above definition may be ambiguous, in simple terms, PhantomJS is a web browser without a graphical user interface.

Since PhantomJS is not usable when it comes to surfing the web, it has a whole set of features that developers love and use for many purposes.

Features

  • Screen capture
  • Page automation
  • Network monitoring
  • Testing
  • Multiplatform, available on major operating systems: Windows, Mac OS X, Linux, and other Unices.
  • Fast and native implementation of web standards: DOM, CSS, JavaScript, Canvas, and SVG. No emulation!
  • Pure headless (no X11) on Linux, ideal for continuous integration systems. Also runs on Amazon EC2, Heroku, and Iron.io.

What is Create.Js?

Create.js is a comprehensive web editing interface for Content Management Systems. It is designed to provide a modern, fully browser-based HTML5 environment for managing content. Create can be adapted to work on almost any content management backend.

The user interface philosophy behind Create is simple: all content that you are allowed to change becomes editable, right there on the page you’re reading. Any modifications you make are retained in your browser and can be sent back to the CMS with a push of a button.

CreateJS is a suite of modular libraries and tools which work together to create interactive content on open web technologies via HTML5.

The libraries are designed to work completely independently, or mixed and matched.

CreateJS is suite of JavaScript libraries and tools for building rich, interactive experiences with HTML5. The CreateJS suite is divided into four libraries.

  1. EaselJS - Makes working with HTML5 canvas easy.
  2. TweenJS - For tweening HTML5 and JavaScript properties
  3. SoundJS - Lets you easily work with HTML5 audio
  4. PreloadJS - Lets you manage and coordinate loading of assets

What is Mithril.Js ?

Mithril is a new javascript MVC framework that aims to make application development more manageable than the “jQuery spaghetti” that is common in legacy systems, and is without the need for steep learning curves that one would encounter with big frameworks like Ember or Angular.

Mithril is a modern client-side Javascript framework for building Single Page Applications.It's small (< 8kb gzip), fast and provides routing and XHR utilities out of the box.

Mithril is used by companies like Vimeo and Nike, and open source platforms like Lichess.

Mithril supports browsers all the way back to IE9, no polyfills required.

The Mithril.js authors are onto something with their tiny (7KB gzipped), easy-to-learn JavaScript MVC library that was originally released in March of 2014 and now has 92 contributors on GitHub. The entire API is just 14 functions and the library is under a thousand lines of code. 

Mithril gives you hierarchical MVC components (just like React), URL routing, customizable data binding, and safe-by-default templates with intelligent DOM difference checking for high-performance rendering.
