ES6 browser framework

"Powerful like React, simple like jQuery"

BunnyJS is a modern Vanilla JS and ES6 library and next-generation front-end framework, package of small stand-alone components without dependencies.

  • No dependencies - can be used in any project anywhere anytime
  • 0 learning curve - you can start right now, just plain JavaScript with simple architecture easy to maintain and extend
  • Designed in mind to build modern, complicated, real world business apps
  • Faster, simpler, enjoyable than any frontend framework
  • Large set of ready components, custom UI elements and utils
  • LTS

Browser support

IE9+, last 2 versions of Chrome, Firefox, Safari, Android 4.4+, iOS 9+

Installation

  1. Install via npm install bunnyjs --save
  2. Rollup.js with babel and npm plugins is recommended for transpiling and bundling.
  3. Or you can just use Assets Builder which will automatically build your future JS and CSS with 1 command.
  4. Or just include into HTML already transpiled and minified JS from dists folder or any CDN.
  5. Probably some polyfills for IE might be required depending on Component.

Extending BunnyJS and Vanilla JS objects

Recommended way to use any of BunnyJS component is - "do not change the code you do not own". That means do not modify native prototypes or any 3rd party code.

  1. Create some base or core folder in your app,
  2. Extend BunnyJS objects with Object.assign() or Object.create
  3. Now everywhere in your project import custom file and not directly BunnyJS's file.
import { Component as BunnyComponent } from 'bunnyjs/src/...';

export const Component = Object.assign({}, BunnyComponent, {

    init(arg) {
        // do whatever you want
        console.log(arg);

        // call default (parent)
        return BunnyComponent.init(arg);
    }

});

Components

  1. Form processing with native API, AJAX submit, file upload, image preview, data binding and more
  2. Native HTML5 form validation (View example)
  3. Facebook-like Messenger
  4. Custom selects, spinners,
  5. DOM utils, ready(), events
  6. Libraries for Date, URL, File, Image
  7. Ajax, APIs
  8. Routing
  9. Template engine
  10. DataTable and Pagination (View example)
  11. Calendar and DatePicker
  12. Autocomplete, Dropdown
  13. Element, positions, coordinates, smooth scrolling
  14. Dependency Injection, Inversion of control

Architecture

  1. Separation of concerns, loose coupling, modularity
  2. Functional programming
  3. ES6 import/exports, Promises
  4. Native Browser API, polyfills were needed
  5. Object literal notation, no prototypes, "classes" , "new"
  6. Object composition over inheritance
  7. Dependency injection

Local development, examples and dists generation

  • Make sure to install npm install assets-builder first.

Experimental components based on DOMObserver (Mutation Observer)

Learn how to build Vanilla JavaScript components on Medium.

src/DOMObserver may be used to listen for DOM events like when new tag (component) was inserted into DOM or removed. It is based on latest Mutation Observer API (IE11+) and allows to automatically init components inserted into DOM later.

BunnyJS provides an experimental base abstract src/Component which may be used to create custom components:

<script src="https://unpkg.com/bunnyjs/dist/component.min.js"></script>

Below is Clock example from Inferno. As you can see you can do everything in Vanilla JS with less code, size and it works natively.

const MyClock = Object.assign({}, Component, {

  tagName: 'clock',

  attributes: {
    date: new Date,
  },

  addEvents(clock) {
    clock._timer = setInterval(() => {
      clock.date = new Date;
    }, 1000);
  },

  uninit(clock) {
    clearInterval(clock._timer);
  },

  __date(clock, newVal) {
    clock.textContent = newVal.toLocaleTimeString();
  }

});

MyClock.register();

Now just document.body.appendChild(document.createElement('clock')) and it works.

To update the whole "state" of the component you may just use Vanilla JS Object.assign(component, {stateObject}).

For example, you have a simple clicker. By clicking on it btn.counter is increased. You can update counter with btn.counter = 1 or Object.assign(document.getElementsByTagName('btn')[0], {counter: 1});

You may also set default counter value with <btn counter="6">

For more examples look in examples/component folder.
