Getting Started

Installation

You can install the module via npm:

npm install livesey-routing

Usage

Module supports both ECMAScript and CommonJS:

To use the module in your project(ESM):

import http from 'node:http';
import { Router, RouteBuilder } from 'livesey-routing';

const router = new RouteBuilder()
  .get('/hello/:name', (req, res) => {
    const name = req.params.name;
    res.json({ message: `Hello, ${name}!` });
  })
  .post('/data', async (req, res) => {
    const data = await req.parseBody();
    res.json({ received: data });
  })
  .build();

(async () => {
  const server = http.createServer((req, res) => {
    router.handleRequest(req, res);
  });

  const port = 3000;
  server.listen(port, () => {
    console.log(`Server running at http://localhost:${port}/`);
  });
})();

To use the module in your project(CJS):

const http = require('node:http');
const { Router, RouteBuilder } = require('livesey-routing');

const router = new RouteBuilder()
  .get('/hello/:name', (req, res) => {
    const name = req.params.name;
    res.json({ message: `Hello, ${name}!` });
  })
  .post('/data', async (req, res) => {
    const data = await req.parseBody();
    res.json({ received: data });
  })
  .build();

(async () => {
  const server = http.createServer((req, res) => {
    router.handleRequest(req, res);
  });

  const port = 3000;
  server.listen(port, () => {
    console.log(`Server running at http://localhost:${port}/`);
  });
})();

Features

Request Class

The Request class provides methods to handle and parse incoming HTTP requests, including access to URL parameters, headers, and the request body.

import { Request } from 'livesey-routing';

const request = new Request(req);

// Access request method
const method = request.method;

// Access URL parameters
const params = request.extractParams('/hello/:name');

// Access request body
const body = await request.parseBody();

Response Class

The Response class simplifies sending responses to the client.

import { Response } from 'livesey-routing';

const response = new Response(res);

// Send a JSON response
response.json({ message: 'Success' });

// Send a plain text response
response.send('Hello, world!');

// Set status code
response.status(404).send('Not Found');

Routing

Routing allows you to define custom routes and their associated handlers using the RouteBuilder class.

import { RouteBuilder } from 'livesey-routing';

const router = new RouteBuilder()
  .get('/user/:id', (req, res) => {
    const userId = req.params.id;
    res.json({ userId });
  })
  .post('/submit', async (req, res) => {
    const data = await req.parseBody();
    res.json({ received: data });
  })
  .put('/update/:id', async (req, res) => {
    const userId = req.params.id;
    res.json({ message: `Updated user ${userId}` });
  })
  .delete('/delete/:id', (req, res) => {
    const userId = req.params.id;
    res.json({ message: `Deleted user ${userId}` });
  })
  .build();

Middleware and Nested Routers

You can use middleware and nested routers to structure your application routes more effectively.

import { Router, RouteBuilder } from 'livesey-routing';

const apiRouter = new RouteBuilder()
  .get('/search/:query', (req, res) => {
    const query = req.params.query;
    res.json({ query });
  })
  .build();

const appRouter = Router.use('/api', apiRouter);

const server = http.createServer((req, res) => {
  appRouter.handleRequest(req, res);
});

const port = 3000;
server.listen(port, () => {
  console.log(`Server running at http://localhost:${port}/`);
});
