Router

A high-performance basic router works anywhere.

Features

Based on radix tree: Compared with routers based on regular expressions, we have better performance in most of the cases, which can significantly increase the speed of your project, and as the project scale increases, the performance will also increase exponentially.
Stupid rules: We will always match according to the rules of "Static > Param > Any". For "static routes", we always match strictly equal strings. For "param routes", we will match 1 or more characters, ending with "/". For "any routes", we will match 0 or more characters.

Nodejs

Installation:

npm i zhmushan/router#v2

Create index.js:

// import * as http from "http";
// import { Node } from "router";

const http = require("http");
const Node = require("router").Node;

const root = new Node();

root.add("/:user", (p) => {
  return p.get("user");
});

http.createServer((req, res) => {
  const [h, p] = root.find(req.url);

  if (h) {
    const result = h(p);
    res.end(result);
  } else {
    res.end("Not Found");
  }
}).listen(8080);

console.log("server listening on http://localhost:8080");

Run:

node index.js

Browse to http://localhost:8080/your_name and you should see "your_name" on the page.
