import Router from '@nichoth/routes'

// cjs

example

Get a router instance

import Router from '@nichoth/routes'
var router = new Router()

Add some routes

router.addRoute('/articles', getArticles);
router.addRoute('/articles/:slug', getArticleBySlug);
router.addRoute('/articles/search/*', searchForArticles);

// can also chain the method calls
router
    .addRoute('/foo', () => {/* ... */})
    .addRoute('/bar', () => {/* ... */})

Find a match

const match = router.match('/articles');
// => RouteMatch

The match object

interface RouteMatch {
    params:Record<string, string>;  // <-- e.g. { slug: 'article-title' }
    splats:string[];
    route:string;
    next?:((...any)=>any)|null;
    action?:(...any)=>any;
    index?:number;
}

You'll get null back if no route matches the provided URL. Otherwise, the route match will provide all the useful information you need inside an object.
