What is trouter?
Trouter is a lightweight and fast router for Node.js that allows you to define routes and handle HTTP requests. It is designed to be minimalistic and efficient, making it suitable for building small to medium-sized web applications and APIs.
What are trouter's main functionalities?
Basic Routing
This feature allows you to define basic routes for handling HTTP GET requests. The code sample demonstrates how to create a simple route that responds with 'Hello, world!' when accessed.
const Trouter = require('trouter');
const router = new Trouter();
router.get('/hello', (req, res) => {
res.end('Hello, world!');
});
// Simulate a request
const req = { method: 'GET', url: '/hello' };
const res = { end: console.log };
router.find(req.method, req.url).handlers[0](req, res);
Route Parameters
This feature allows you to define routes with parameters. The code sample demonstrates how to create a route that captures a user ID from the URL and responds with the user ID.
const Trouter = require('trouter');
const router = new Trouter();
router.get('/user/:id', (req, res) => {
const { id } = req.params;
res.end(`User ID: ${id}`);
});
// Simulate a request
const req = { method: 'GET', url: '/user/123', params: { id: '123' } };
const res = { end: console.log };
router.find(req.method, req.url).handlers[0](req, res);
Middleware Support
This feature allows you to use middleware functions in your routes. The code sample demonstrates how to create a logger middleware that logs the request method and URL before handling the request.
const Trouter = require('trouter');
const router = new Trouter();
const logger = (req, res, next) => {
console.log(`${req.method} ${req.url}`);
next();
};
router.use(logger);
router.get('/hello', (req, res) => {
res.end('Hello, world!');
});
// Simulate a request
const req = { method: 'GET', url: '/hello' };
const res = { end: console.log };
const { handlers } = router.find(req.method, req.url);
handlers[0](req, res, () => handlers[1](req, res));
