micro-http-router

Build Status Coverage Status

micro-http-router is a simple, Express-like router for micro that uses a radix tree via radix-router. It supports most, if not all, of the HTTP verbs, and tries to be as lightweight and quick as possible.

Installation

micro-http-router is an npm package and you should have the latest Node.js and npm installed.

> npm i --save micro-http-router

https://www.npmjs.com/package/micro-http-router

Usage

const micro = require('micro');
const Router = require('micro-http-router');
 
// Initialize the router
const router = new Router();
 
// Define a basic GET request
router.route({
    path: '/',
    method: 'GET',
    handler: (req, res) => {
        return 'Hello, world';
    }
});
 
// Define a basic GET request with a middleware function
router.route({
    path: '/',
    method: 'GET',
    before: (req, res) => {
        req.user = {};
        req.user.name = 'John Doe';
    },
    handler: (req, res) => {
        return `Hello, ${ req.user.name }`;
    }
});
 
// Express-like routing helpers
router.get('/', (req, res) => {
    return 'Hello, world';
});
 
// Async body parsing
router.post('/', async (req, res) => {
    const body = await micro.json(req);
    return body;
});
 
// Any number of route parameters are supported
// Access via the req.params array
router.get('/:first/:second', (req, res) => {
    const first = req.params.first;
    const second = req.params.second;
    return `Your first parameter is ${ first } and your second is ${ second }.`;
});
 
// Start micro and listen
const server = micro((req, res) => router.handle(req, res));
const port = 3000;
server.listen(port);
console.log(`micro is listening on port: ${ port }`);

Changelog (1.2.1 => 1.3.0)

New in 1.3.0

Updated dependencies, including radix-router. The only major change is that in place of a request parameter array, the parameters are added to the req.params object in a named fashion. If you define a route as '/:id', instead of using req.params[0] to get the passed in ID, you can simply use req.params.id. Additionally, merged in PR #3 which adds a full stack trace to the error output when debug is set to true.

New in 1.2.0

Add debug: true to the router options object to enable debug logging. Any thrown errors will have their error messages returned as the response body. Useful when developing with micro-http-router and you are unexpectedly receiving 500 Internal Server Errors.

New in 1.1.0

Added before option to route options. This serves as a single layer of middleware allowing you to do the following:

const micro = require('micro');
const Router = require('micro-http-router');
 
const beforeHandler = function (req, res) {
    req.user = {};
    req.user.name = 'John Doe';
};
 
// Initialize the router
const router = new Router();
 
// Define a basic GET request with a middleware function
router.route({
    path: '/',
    method: 'GET',
    before: beforeHandler,
    handler: (req, res) => {
        return `Hello, ${ req.user.name }`;
    }
});
 
// or define it with your get shorthand
router.get('/', beforeHandler, (req, res) => {
    return `Hello, ${ req.user.name }`;
});
 
// Start micro and listen
const server = micro((req, res) => router.handle(req, res));
const port = 3000;
server.listen(port);
console.log(`micro is listening on port: ${ port }`);

Tests

micro-http-router comes with a few AVA tests to help ensure correct routing behavior.
