Small Discussion About ESLINT?

What is EsLint?

ESLint is an open source JavaScript linting utility originally created by Nicholas C. Zakas in June 2013. Code linting is a type of static analysis that is frequently used to find problematic patterns or code that doesn't adhere to certain style guidelines.

The primary reason ESLint was created was to allow developers to create their own linting rules. ESLint is designed to have all rules completely pluggable. The default rules are written just like any plugin rules would be. They can all follow the same pattern, both for the rules themselves as well as tests. While ESLint will ship with some built-in rules to make it useful from the start, you’ll be able to dynamically load rules at any point in time.

ESLint is written using Node.js to provide a fast runtime environment and easy installation via npm.

ESLint is a tool for identifying and reporting on patterns found in ECMAScript/JavaScript code, with the goal of making code more consistent and avoiding bugs. 

Features

  • ESLint uses Espree for JavaScript parsing.
  • ESLint uses an AST to evaluate patterns in code.
  • ESLint is completely pluggable, every single rule is a plugin and you can add more at runtime.​

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

What is Supersonic ?

Supersonic is a robust user interface framework (UI) for developing hybrid mobile applications. The framework integrates with any REST API (Application Programming Interface) and allows data interaction/modification in the backend. With Supersonic, one can design API-connected mobile applications for iOS and Android.

Supersonic is a framework with an elegant balance of simplicity and power. By using the best of what AngularJS, web components and HTML5 have to offer, Supersonic has crafted a level of sophistication that is years ahead of the competition.

Supersonic UI is a game-changer. It's an Ionic fork that changes the way you think about hybrid app performance. Supersonic's declarative UI style makes building complex mobile apps a breeze. In the background, the seamless interplay of native UI and HTML5 bakes an end-result that is 100% indistinguishable from any native app. 

Supersonic bridges the gap by using native UI elements when HTML and CSS just don't cut it. No more position: fixed; header bars, slow tabs or choppy animations. Page transitions, modals, navigation bars, tab bars, drawers – and a whole lot more – are fully native. That means unparalleled performance and no App Store rejections.

What is Guard?
Guards make sure that the application user with the access permission can access that particular area in the application.
It is mainly used to protect routes.

Guard Types:

  • CanActivate - this guard helps decide whether a route can be activated or not.
  • CanActivateChild - this guard helps to decide whether children routes of a route can be activated or not.
  • CanDeactivate - this guard helps decide whether a route can be deactivated or not.
  • CanLoad - this guard helps decide whether a module can be loaded lazily or not

Guards can be implemented in different ways, but after all it really boils down to a function that returns either Observable<boolean>, Promise<boolean> or boolean. In addition, guards are registered using providers, so they can be injected by Angular when needed.

To register a guard we need to define a token and the guard function. Here’s what a super simple guard implementation could look like:


@NgModule({
  ...
  providers: [
    provide: 'CanAlwaysActivateGuard',
    useValue: () => {
      return true;
    }
  ],
  ...
})
export class AppModule {}

What is Mojito?

Mojito is an environment agnostic, MVC web application framework architected by Ric Allinson which supports agile development of web applications. ... Mojito is capable of running on both client(browser) and the server(Node.js) because both client and server side components are written in single language

Mojito provides seamless MVC framework to manage code base on server as well as on client side. The advantages of using Mojito are:

Single Language: Mojito is entirely built on JavaScript and hence the application code can run on server as well as can be deployed to client. This will remove the need for client to fetch data from the server.
Run-time Environment: Mojito has inbuilt capability to determine whether client can run JavaScript before deploying the code. If the client cannot execute JavaScript (JavaScript might be disabled at client side), then Mojito will execute the application code on the server.
Internationalization: Mojito has inbuilt library to handle Internationalization and localization.

Mojito has two unique features to empower you on this area.

Runtime context : which is a predefined set of dimensions/variables with a finite number of possibilities/values that will define the state of the execution at any given time.
Environment agnostic : the unique ability to run the same code in different runtimes. E.g.: browser, server, iOS UIWebView or any other phoneGap similar runtime.
