Simple vanilla JavaScript router to be used inside a single page app to add routing capabilities.
The router comes with zero dependencies and can be used with any other libraries. It's based on the hashchange-Event.
$ npm install --save vanilla-ui-router
As UMD module this runs everywhere (ES6 modules, CommonJS, AMD and with good ol’ globals).
Let's assume your initial markup has the following structure:
<!DOCTYPE html>
<html>
<head>
<link rel="stylesheet" type="text/css" href="styles.min.css" />
</head>
<body>
<!-- Entry point, dynamic content is rendered into this DOM element -->
<main id="app"></main>
<!-- Bundle where your JavaScript logic lives, even the router configuration -->
<script src="bundle.js"></script>
</body>
</html>Then you could configure the router with the following JavaScript:
import {createRouter} from 'vanilla-ui-router';
// Initialize the router with the dynamic DOM entry point
const router = createRouter(document.getElementById('app'));
router
// Start route: The server side URL without a hash
.addRoute('', () => {
/*
Use navigateTo(…) to make dynamic route changes, i.e. to redirect to another route
*/
router.navigateTo('home');
})
.addRoute('home', (domEntryPoint) => {
domEntryPoint.textContent = 'I am the home route.';
})
.addRoute('about/:aboutId/:editable', (domEntryPoint, routeParams) => {
console.log('I am the about route.');
/*
routeParams are extracted from the URL and are casted to the correct type
(Number/Boolean/String)
*/
console.log(routeParams); // => { aboutId: 42, editable:false }
})
/*
If routes get more complex, e.g. you need to render a template URL,
pass a configuration object as second parameter (instead of the function)
*/
.addRoute('route-with-template-url', {
templateUrl: 'path/to/template.html' // is loaded and gets rendered
})
.addRoute('route-with-template-string/:id', {
templateString: '<p>Lorem ipsum dolor.</p>',
routeHandler: (domEntryPoint, routeParams) => {
/*
It's called just after rendering the template, so you can add route-specific logic.
But only if needed!
*/
}
})
/*
You can also define a templateId, i.e. if you have a template-script inside
your markup like:
<script type="text/template" id="template42">
<p>
Lorem ipsum dolor sit amet, consectetur adipisicing elit. Dolor, tenetur?
</p>
</script>
*/
.addRoute('route-with-template-id/:id', {
templateId: 'template42'
})
.addRoute('route-with-dispose', {
routeHandler: () => {},
dispose: () => {
// Is called before navigating to another route to do some cleanup if needed.
}
})
.addRoute('inject-custom-data', {
routeHandler: (domEntryPoint, routeParams, {customData}) => {
// It's passed as the last parameter of the route, for instance to pass a redux store.
},
}, { customData: 'moep'}) // if you need to pass custom data to your routes
.otherwise(() => {
// If no route configuration matches, the otherwise route is invoked.
console.log('I am the otherwise route');
router.navigateTo('404');
