Lightweight and fast router for JavaScript based on Radix Tree.

Install package:

# npm npm i radix3 # yarn yarn add radix3 # pnpm pnpm i radix3

Import:

// ESM import { createRouter } from 'radix3' // CJS const { createRouter } = require('radix3')

Create a router instance and insert routes:

const router = createRouter(/* options */) router.insert('/path', { payload: 'this path' }) router.insert('/path/:name', { payload: 'named route' }) router.insert('/path/foo/**', { payload: 'wildcard route' }) router.insert('/path/foo/**:name', { payload: 'named wildcard route' })

*Match route to access matched data:

// { payload: 'this path' } router.lookup('/path') // { payload: 'named route', params: { name: 'fooval' } } router.lookup('/path/fooval') // { payload: 'wildcard route' } router.lookup('/path/foo/bar/baz') // null (no route matched for/) router.lookup('/')

path can be static or using :placeholders and ** for wildcard paths.

The data object will be returned on matching params. It should be an object like { handler } and not containing reserved keyword params.

Returns matched data for path with optional params key if mached route using placeholders.

Remove route matching path.

You can initialize router instance with options:

const router = createRouter({ strictTrailingSlash: true, routes: { '/foo': {} } })

• routes: An object specifying initial routes to add
• strictTrailingSlash: By default router ignored trailing slash for matching and adding routes. When set to true, matching with trailing slash is different.

Experimental feature: Behavior might change in a semver-minor release.

Creates a multi matcher from router tree that can match all routes matching path:

import { createRouter, toRouteMatcher } from 'radix3' const router = createRouter({ routes: { '/foo': { m: 'foo' }, // Matches /foo only '/foo/**': { m: 'foo/**' }, // Matches /foo/<any> '/foo/bar': { m: 'foo/bar' }, // Matches /foo/bar only '/foo/bar/baz': { m: 'foo/bar/baz' }, // Matches /foo/bar/baz only '/foo/*/baz': { m: 'foo/*/baz' } // Matches /foo/<any>/baz } }) const matcher = toRouteMatcher(router) const matches = matcher.matchAll('/foo/bar/baz') // [ // { // "m": "foo/**", // }, // { // "m": "foo/*/baz", // }, // { // "m": "foo/bar/baz", // }, // ]

See benchmark.
