To add LF Widgets to your project, you can install it via yarn:
yarn add lf-widgets
Or npm:
npm install lf-widgets
After installing, you can import and use LF Widgets components in your project. Here's a quick example of how to use the <lf-button> component:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8" />
<title>LF Widgets Example</title>
<script type="module" src="./path/to/lf-widgets/dist/index.js"></script>
</head>
<body>
<lf-button lf-label="Click me!" />
</body>
</html>
Make sure to replace ./path/to/lf-widgets/dist/index.js with the correct path to the index.js file in your node_modules/lf-widgets directory.
The event handling is wrapped in a single event, emitted by the root element. In this small example we add a listener to the button component, performing different actions for different situations:
const myButton = document.createElement("lf-button");
myButton.addEventListener("lf-button-event", (e) => {
const { eventType } = e.detail;
switch (eventType) {
case "click":
console.log("Click!");
break;
case "blur":
console.log("Blur!");
break;
case "ready":
console.log("The button is ready!");
break;
case "unmount":
console.log("The button has been removed from the DOM!");
break;
}
document.body.appendChild(myButton);
});
For detailed information about each component, including available properties, events, and methods, please refer to the showcase.
