Router

A simple, lightweight router for Node.js with support for middleware and route-specific handlers.

Installation

To use this router, you need to have Node.js installed on your machine. You can then include the Router class in your project.

npm install http-simple-router

Usage

Here's a step-by-step guide on how to use the Router class. Creating a Router

First, require the Router class and create a new instance:

const http = require('http');
const Router = require('http-simple-router');

const router = new Router();

Adding Routes

You can add routes to your router using the addRoute method. The method takes three arguments: the URL, the HTTP method, and a handler function.

router.addRoute('/test', 'POST', (req, res) => {
    console.log(req);
    res.end("Response from /test");
});

Adding Middleware

You can add middleware to your router using the use method. Middleware can be applied globally or to specific routes. Global Middleware

To add a middleware that will run for every route:

router.use((req, res, next) => {
    console.log("Global middleware");
    next();
});

Route-Specific Middleware

To add a middleware that will run only for a specific route:

router.addRoute('/test', 'POST', (req, res) => {
    console.log(req);
    res.end("Response from /test");
})
.use((req, res, next) => {
    console.log("Route-specific middleware");
    next();
});

Handling Requests

Create an HTTP server and use the router to handle incoming requests:

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

server.listen(3000, () => {
    console.log("Server running on port 3000");
});

Error Handling

The router provides built-in methods for handling route not found and method not allowed errors:

routeNotFound(res): Sends a 404 Not Found response.
methodNotAllowed(res): Sends a 405 Method Not Allowed response.

These methods are automatically called when a route or method is not found. Example

Here's a complete example:

const http = require('http');
const Router = require('http-simple-router');

const router = new Router();

router.addRoute('/test', 'POST', (req, res) => {
    console.log(req);
    res.end("Response from /test");
})
