data-component
Use the data-component in HTML to bind a JavaScript class to an element.
Simple usage
When using the config.components property, the framework will find components by using a selector combining the data-component attribute and the key declared in the configuration.
In the following example, both of the imported components will be mounted. One with the name Component, mounted on [data-component="Component"] elements found in the DOM. The other with the name CustomName, mounted on [data-component="CustomName"] elements.
import { Base, createApp } from '@studiometa/js-toolkit';
import Component from './Component.js';
import OtherComponent from './OtherComponent.js';
class App extends Base {
static config = {
name: 'App',
components: {
Component,
CustomName: OtherComponent,
},
};
}
export default createApp(App);<html>
<head>
<meta charset="utf-8" />
<meta name="viewport" content="width=device-width, initial-scale=1" />
<title>App</title>
</head>
<body>
<div data-component="Component"></div>
<div data-component="CustomName"></div>
</body>
</html>Multiple components on a single HTML element
Mutliptle components can be declared on a single HTMLElement by declaring multiple names in the data-component attribute separated by a whitespace.
In the following example, both components from our previous app will be mounted on the same element.
<html>
<head>
<meta charset="utf-8" />
<meta name="viewport" content="width=device-width, initial-scale=1" />
<title>App</title>
</head>
<body>
<div data-component="Component CustomName"></div>
</body>
</html>
