PEARL JS

[@pearl-js/pearl](https://www.npmjs.com/package/@pearl-js/pearl)

A Javascript library for building Browser User Interfaces. Pearl JS is a component base javascript rendering library for creating User Interfaces in the browser.

Installation

Pearl Js can be added to a website by adding the following script in the html of your website.

<script src="https://cdn.jsdelivr.net/npm/@pearl-js/[email protected]/umd/pearljs.production.js" ></script>

Using npm or yarn

If your are using npm or yarn all you have to do is add the package to your project.

# npm
npm install @pearl-js/pearl

# yarn
yarn add @pearl-js/pearl

Usage

Pearl can be used directly using javascript syntax but this is usually hard since you will write alot of functions so we developed a babel plugin that transforms jsx into pearl functions.

Using plain Javascript

const button = Pearl.createElement("button", {
  attributes: {
    id: "mybutton",
    className: "btn btn-primary"
  },
  events: {
    click: (e)=> {
      console.log('clicked')
    }
  },
  children: [
    "Click Me"
  ]
})

Pearl.append(button, document.getElementById('button-cover'), ()=>{
  console.log('mounted')
})

Using jsx

import Pearl, {append} from "@pearl-js/pearl";


const button = <button id="mybutton" onClick={(e)=>{
  console.log('clicked')
}} className="btn btn-primary" >Click Me</button>

append(button, document.getElementById('button-cover'), ()=>{
  console.log('mounted')
})

Both of the above create the same button.

If you want to use jsx you should install babel-plugin-jsx-to-pearl and also @babel/plugin-syntax-jsx and add them to your babel configuration. These will transform all jsx code into Pearl functions. And always add @babel/plugin-syntax-jsx before babel-plugin-jsx-to-pearl.

# using npm
npm install babel-plugin-jsx-to-pearl --save-dev

# using yarn
yarn add babel-plugin-jsx-to-pearl --dev

Inside the babel configuration file

// .babelrc
{
  ...
  "plugins": [
    ...
    "@babel/plugin-syntax-jsx",
    "babel-plugin-jsx-to-pearl"
    ...
  ]
}
