🌳 radix3
Lightweight and fast router for JavaScript based on Radix Tree.
Usage
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:
router.lookup("/path");
// { payload: 'this path' }
router.lookup("/path/fooval");
// { payload: 'named route', params: { name: 'fooval' } }
router.lookup("/path/foo/bar/baz");
// { payload: 'wildcard route' }
router.lookup("/");
// null (no route matched for/)
Methods
router.insert(path, data)
path
can be static or using :placeholder
or **
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
.
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": {},
},
});
routes
: An object specifying initial routes to addstrictTrailingSlash
: By default router ignored trailing slash for matching and adding routes. When set totrue
, matching with trailing slash is different.
Route Matcher
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",
// },
// ]
Route Matcher Export
It is also possible to export and then rehydrate a matcher from pre-compiled rules.
import { exportMatcher, createMatcherFromExport } from "radix3";
// Assuming you already have a matcher
// you can export this to a JSON-type object
const json = exportMatcher(matcher);
// and then rehydrate this later
const newMatcher = createMatcherFromExport(json);
const matches = newMatcher.matchAll("/foo/bar/baz");
Performance
