LemonadeJS v3: Reactive micro library
Create amazing web-based interfaces with LemonadeJS
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 transpilers, 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

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() {
let self = this;
self.test = function(e) {
console.log(e);
e.preventDefault();
}
return `<input type="button" value="Click test" onclick="self.test(e);"/>`;
}
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>
