Usage

Install package:

# npm
npm i @immobiliarelabs/radix3

# yarn
yarn add @immobiliarelabs/radix3

# pnpm
pnpm i @immobiliarelabs/radix3

Import:

// ESM
import { createRouter } from '@immobiliarelabs/radix3'

// CJS
const { createRouter } = require('@immobiliarelabs/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('/')

Methods

router.insert(path, data)

path can be static or using :placeholders and ** for wildcard paths or else using ::functionName for functional match.

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

router.lookup(path)

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

router.remove(path)

Remove route matching path.

Options

You can initialize router instance with options:

const router = createRouter({
  strictTrailingSlash: true,
  routes: {
    '/foo': {},
    '/::len': {} // Matches all routes /<two length string>/
  },
  funcs: {
    len: (str) => str.length === 2,
  }
})

• 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.
• funcs: An object containing the functions used in the routes
• parseParameters: By default this variable is set to true. When set to false, the params attribute will not be present in the lookup function output object. Putting this parameter to false increases the lookup performance by 3x for dynamic routes.

Route Matcher

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
  },
  funcs: {
    len: (str) => str.length === 2,
  }
})

const matcher = toRouteMatcher(router)

const matches = matcher.matchAll('/foo/bar/baz')

// [
//   {
//     "m": "foo/**",
//   },
//   {
//     "m": "foo/*/baz",
//   },
//   {
//     "m": "foo/bar/baz",
//   },
// ]
