LemonadeJS v4: Reactive micro library

Create amazing web-based interfaces with LemonadeJS

Micro Library

LemonadeJS is a super lightweight reactive vanilla javascript micro-library (7 KBytes). It helps to integrate the JavaScript (controllers) and the HTML (view). It supports two-way data binding and integrates natively with jSuites to help to create amazing interfaces quicker.

It would help you deliver reusable components and does not require transpiler, babel, or hundreds of other dependencies. It works just fine in any javascript dev environment. LemonadeJS has a quick learning curve, keeps coding fun, and is very close to native JS.

Make rich and user-friendly web interfaces and applications
Handle complicated data inputs with ease and convenience
Improve the software user experience
Create rich CRUDS and beautiful UI
Highly flexible and customizable
Lightweight and simple to use

export default function App() {
  let self = this;
  self.count = 1;
  return `<div>
        <div><Hello /></div>
        <p>You clicked {{self.count}} times</p>
        <button onclick="self.count++;">Click me</button>
  </div>`;
}

Browser

Simplicity to run in the browser without dependencies, servers, transpiler.

<html>
<body>
<div id="root"></div>
<script src="https://cdn.jsdelivr.net/npm/lemonadejs/dist/lemonade.min.js"></script>
<script>
function Hello() {
    let self = this;
    return `<h1>{{self.title}}</h1>`;
}

function App() {
    let self = this;
    self.count = 1;
    return `<>
      <Hello title="your title" />
      <p>You clicked {{self.count}} times</p>
      <button onclick="self.count++;">Click me</button>
    </>`;
}
lemonade.render(App, document.getElementById('root'));
</script>
</body>
</html>

Creating a table from an array of objects

import lemonade from "lemonadejs";

export default function Component() {
    let self = this;

    self.rows = [
        { title:'Google', description: 'The alpha search engine...' },
        { title:'Bing', description: 'The microsoft search engine...' },
        { title:'Duckduckgo', description: 'Privacy in the first place...' },
    ];

    // Custom components such as List should always be unique inside a real tag.
    return `<table cellpadding="6">
        <thead><tr><th>Title</th><th>Description</th></th></thead>
        <tbody @loop="self.rows">
            <tr><td>{{self.title}}</td><td>{{self.description}}</td></tr>
        </tbody>
    </table>`;
}

The event object

<html>
<body>
<div id='root'></div>
<script src="https://cdn.jsdelivr.net/npm/lemonadejs/dist/lemonade.min.js"></script>
<script>
function Component() {
    // Create the self object
    let self = this;
    self.test = function(e) {
        console.log(e);
        e.preventDefault();
    }
    // The property call is added to the observable list when added to the DOM
    return `<input type="button" value="Click test" onclick="self.test(e);"/>`;
}

// Render the LemonadeJS element into the DOM
lemonade.render(Component, document.getElementById('root'));
</script>
</body>
</html>

Enable/disable HTML elements

<html>
<body>
<div id='root'></div>
<script src="https://cdn.jsdelivr.net/npm/lemonadejs/dist/lemonade.min.js"></script>
<script>
function App() {
    let self = this;
    self.disabled = false;
    return `<>
      <button onclick="self.disabled = !self.disabled">Toggle</button>
      <input type="text" disabled="{{self.disabled}}" />
    </>`;
}
lemonade.render(App, document.getElementById('root'));
</script>
</body>
</html>

Reactive Web Components

<hello-element title="Hello world" />

class HelloElement extends HTMLElement {
    constructor() {
        super();
    }
 
    render() {
        let self = this;
        return `<>
            <h1>{{self.title}}</h1>
            <input type="button" value="setTitle()"
                onclick="self.title = 'Test'" />
        </>`;
    }
 
    connectedCallback() {
        if (! this.el) {
            lemonade.render(this.render, this, this);
        }
    }
}
 
window.customElements.define('hello-element', HelloElement);
