h3js🌳 rou3
Lightweight and fast router for JavaScript.
Usage
Install:
# ✨ Auto-detect
npx nypm install rou3Import:
ESM (Node.js, Bun, Deno)
import {
createRouter,
addRoute,
findRoute,
removeRoute,
findAllRoutes,
routeToRegExp,
NullProtoObj,
} from "rou3";CDN (Deno and Browsers)
import {
createRouter,
addRoute,
findRoute,
removeRoute,
findAllRoutes,
routeToRegExp,
NullProtoObj,
} from "https://esm.sh/rou3";Create a router instance and insert routes:
import { createRouter, addRoute } from "rou3";
const router = createRouter(/* options */);
addRoute(router, "GET", "/path", { payload: "this path" });
addRoute(router, "POST", "/path/:name", { payload: "named route" });
addRoute(router, "GET", "/path/foo/**", { payload: "wildcard route" });
addRoute(router, "GET", "/path/foo/**:name", {
payload: "named wildcard route",
});Match route to access matched data:
// Returns { payload: 'this path' }
findRoute(router, "GET", "/path");
// Returns { payload: 'named route', params: { name: 'fooval' } }
findRoute(router, "POST", "/path/fooval");
// Returns { payload: 'wildcard route' }
findRoute(router, "GET", "/path/foo/bar/baz");
// Returns undefined (no route matched for/)
findRoute(router, "GET", "/");[!IMPORTANT] Paths should always begin with
/.[!IMPORTANT] Method should always be UPPERCASE.
Compiler
compileRouter(router, opts?)
Compiles the router instance into a faster route-matching function.
IMPORTANT: compileRouter requires eval support with new Function() in the runtime for JIT compilation.
Example:
import { createRouter, addRoute } from "rou3";
import { compileRouter } from "rou3/compiler";
const router = createRouter();
// [add some routes]
const findRoute = compileRouter(router);
const matchAll = compileRouter(router, { matchAll: true });
findRoute("GET", "/path/foo/bar");compileRouterToString(router, functionName?, opts?)
Compile the router instance into a compact runnable code.
IMPORTANT: Route data must be serializable to JSON (i.e., no functions or classes) or implement the toJSON() method to render custom code or you can pass custom serialize function in options.
Example:
import { createRouter, addRoute } from "rou3";
import { compileRouterToString } from "rou3/compiler";
const router = createRouter();
// [add some routes with serializable data]
const compilerCode = compileRouterToString(router, "findRoute");
// "const findRoute=(m, p) => {}"License
