Discussion About Svelte.Js?

What is Svelte?

Svelte is a different take on the idea of building UIs. Rather than being a library that runs in the browser to create your UI, it's a compiler that turns your component into simple JavaScript, with no need for virtual DOM diffing or any of the other techniques that UI libraries use

The web's JavaScript bloat crisis, solved. 

  • Svelte turns your templates into tiny, framework-less vanilla JavaScript.
  • Simple and familiar. Build apps out of composable, easy-to-write blocks using languages you already know.
  • Super fast, rock solid. Compile-time static analysis ensures the browser does no more work than it needs to.

In Svelte, an application is composed from one or more components. A component is a reusable self-contained block of code that encapsulates markup, styles and behaviours that belong together.

Like Ractive and Vue, Svelte promotes the concept of single-file components: a component is just an .html file. Here's a simple example:

<!-- App.html -->
<h1>Hello {{name}}!</h1>
Svelte turns this into a JavaScript module that you can import into your app:

// main.js
import App from './App.html';

const app = new App({
  target: document.querySelector( 'main' ),
  data: { name: 'world' }
});

// change the data associated with the template
app.set({ name: 'everybody' });

// detach the component and clean everything up
app.destroy();

What is Axios?

Axios is a promise-based HTTP client that works both in the browser and in a node.js environment. It basically provides a single API for dealing with XMLHttpRequest s and node's http interface. Besides that, it wraps the requests using a polyfill for ES6 new's promise syntax

Node Command

npm install axios

Bower Command

bower install axios

Features

  • Make XMLHttpRequests from the browser
  • Make http requests from node.js
  • Supports the Promise API
  • Intercept request and response
  • Transform request and response data
  • Cancel requests
  • Automatic transforms for JSON data
  • Client-side support for protecting against XSRF

The user interface is split up into three sections:

  • GET Request
  • GET Request with Parameters
  • POST Request

With each of these three sections the user is able to try out a specific use case for Axios.

What is KeyStone.Js?
KeystoneJS is a powerful Node.js content management system and web app framework built on express and mongoose. Keystone makes it easy to create sophisticated web sites and apps, and comes with a beautiful auto-generated Admin UI.

KeystoneJS is the easiest way to build database-driven websites, applications and APIs in Node.js.

Features:

  • Express.js and MongoDB
  • Dynamic Routes
  • Database Fields
  • Auto-generated Admin UI
  • Simpler Code
  • Form Processing
  • Session Management
  • Email Sending

Keystone uses Mongoose, the leading ODM for node.js and MongoDB, and gives you a single place for your schema, validation rules and logic.

Keystone can configure Express for you, or you can take over and treat Keystone like any other Express middleware.

You can also easily integrate it into an existing Express app.

NPM Command
npm install -g generator-keystone

YO Generator
$ yo keystone

What is Synaptic ?

Synaptic is a javascript neural network library for node.js and the browser, its generalized algorithm is architecture-free, so you can build and train basically any type of first order or even second order neural network architectures.

This library includes a few built-in architectures like multilayer perceptrons, multilayer long-short term memory networks (LSTM), liquid state machines or Hopfield networks, and a trainer capable of training any given network, which includes built-in training tasks/tests like solving an XOR, completing a Distracted Sequence Recall task or an Embedded Reber Grammar test, so you can easily test and compare the performance of different architectures.

Npm Command

npm install synaptic --save

Bower Command

bower install synaptic

Sample Layer created using Synaptic:

What is Casper.Js?
CasperJS is a navigation scripting & testing utility for the PhantomJS (WebKit) and SlimerJS (Gecko) headless browsers, written in Javascript.

CasperJS allows you to build full navigation scenarios using high-level functions and a straight forward interface to accomplish all sizes of tasks.

CasperJS comes with a basic testing suite that allows you to run full featured tests without the overhead of a full browser. Output the tests to xunit for long term code health as well.

Capture data from web pages simply that don't contain APIs. Validate your production environment on a regular basis. Alternatively, use this to load your application with data.

Example Code:

var casper = require('casper').create();

casper.start('http://casperjs.org/', function() {
    this.echo(this.getTitle());
});

casper.thenOpen('http://phantomjs.org', function() {
    this.echo(this.getTitle());
});

What is Mercury.Js?

Mercury is the creation of Raynos and available as open source under MIT license. It is fast growing in popularity and is getting lot of attention from the community of JavaScript Developers.

Mercury appears to be inspired by react and runs on the concept of virtual DOM rendering. It is modern JavaScript framework, fully modular and can be used to the extent you need.

Looking at the underlying concepts, compact size, modular approach, performance and popularity, Mercury makes its place in list of best 10 JavaScript frameworks of modern times

Benefits

  • Mercury leverages virtual-dom which uses an immutable vdom structure
  • Mercury comes with observ-struct which uses immutable data for your state atom
  • Mercury is truly modular, you can trivially swap out subsets of it for other modules
  • Mercury source code itself is maintainable, the modules it uses are all small, well tested and well documented. you should not be afraid to use mercury in production as it's easy to maintain & fix.
  • Mercury encourages zero dom manipulation in your application code. As far as your application is concerned elements do not exist. This means you don't need to reference DOM elements when rendering or when handling events

Mercury is a small glue layer that composes a set of modules that solves a subset of the frontend problem.

NPM Command

npm install mercury
