Create amazing JavaScript reactive applications.

LemonadeJS is a free reactive javascript micro-library (about 6 KBytes). It enhances the integration between the JavaScript (controllers) and the HTML (view). It supports two-way data binding and helps you to deliver great reusable components.

Build modern application using webpack or choose to run direct in the browser without dependencies or transpile.

Modern interfaces

Build modern application using webpack or simple coding direct in the browser without dependencies or transpiling.

See this example on codesandbox

import lemonade from "lemonadejs";
import Hello from "./Hello";

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

  return lemonade.element(template, self, { Hello });
}

Simplicity

Run LemonadeJS in your browser without dependencies or transpiling.

Flexibility

Integrate LemonadeJS on top of any existing application without changing architecture.
Adopt LemonadeJS to specific sections of an existing applications.
Create two-way data binding sections to specific block of the DOM application.

See this example on jsfiddle

<html>
<script src="https://lemonadejs.net/v2/lemonade.js"></script>
<div id="root"></div>
<script>
var Hello = (function() {
    // Receive the properties from the parent
    var self = this;
    let template = `<div>You clicked {{self.number}} times</div>`;
    return lemonade.element(template, self);
});

var App = (function() {
    var self = {
        count: 0,
    };
    // Number is a reference to count in this scope
    let template = `<div>
        <Hello number="{{self.count}}" />
        <button onclick="self.count++">Plus 1</button>
        <button onclick="self.count--">Minus 1</button>
    </div>`;
    return lemonade.element(template, self, { Hello });
});
lemonade.render(App, document.getElementById('root'));
</script>
</html>

New concepts

The Pico Library

The Pico Library brings javascript common components. Each component in the library does not require any dependency and has a limit of 2 kBytes each.

Sugar (Super Global Artifacts)

The LemonadeJS Sugar is a common global container that makes easier communication between different components.

About LemonadeJS

The LemonadeJS is an original micro reactive JavaScript software created to facilitate the integration between the HTML, data, and JavaScript methods in web-based development. It is an efficient and flexible way for building user interfaces. It brings the development as close to the JavaScript vanilla as possible. It has some smart concepts and a powerful optimization that offers a straightforward learning curve. The developer would have the flexibility to extend the development to the browser environment but continue building modern, complex UIs and reusable components.

On the most release, it brings new concepts such as SUGAR (Super Global Artifacts) which is a common container to simplify the communication between components. And PICO is the official component library without dependencies up to 2 KBytes.
