TAT Router
TAT Router is a lightweight Node.js library for handling HTTP requests based on the URL path and HTTP method.
Installation
npm install tat-router
Usage
Creating a router instance
const Router = require("router");
const router = new Router((res) => {
res.writeHead(404, { "Content-Type": "text/plain" });
res.write("404 - Not found!")
res.end();
});
Adding routes
router.add("GET", "/", (res)=>{
res.writeHead(200, {"Content-Type": "text/plain"});
res.write("Hello world!");
res.end();
});
router.add("GET", "/users/:name", (res, params) => {
const name = params.name;
res.writeHead(200, {"Content-Type": "text/plain"});
res.write(`Hello ${name}!`);
res.end();
});
router.add("GET", "/users/:userId/posts/:postId?", (res, params)=>{
const userId = params.userId;
const postId = params.postId || "latest";
res.writeHead(200, { "Content-Type": "application/json" });
res.write(`{userId: "${userId}", postId: "${postId}"}`);
res.end();
});
Handling requests
const req = {
method: "GET",
url: "http://localhost"
};
router.navigate(req, res);
// Hello world!
const req = {
method: "GET",
url: "http://localhost/users/fatih"
};
router.navigate(req, res);
// Hello fatih!
const req = {
method: "GET",
url: "http://localhost/users/12/posts/"
};
router.navigate(req, res);
// {userId: "12", postId: "latest"}
const req = {
method: "GET",
url: "http://localhost/users/12/posts/34"
};
router.navigate(req, res);
// {userId: "12", postId: "34"}
Connecting with HTTP module
http.createServer((req, res) => {
router.navigate(req, res);
}).listen(3000);
