MapRouter

MapRouter is a simple and fast exact-match router middleware for Express that can be used instead of the built-in router.

Requires Node v0.12 or iojs. The module does not run on Node v0.10 as it uses Map constructor which is not enabled by default (you might get it working with the --harmony flag though).

The goals of this router are:

• Should be very fast
• Routes can be added dynamically
• Routes can be removed dynamically

The sacrifices for achieving the goals are:

• Only exact matches, no regular expressions or variable support

This router is suitable for scenarios where you need to add and remove routes very often in runtime.

Usage

Install with npm

npm install map-router

Require in your script

var MapRouter = require('map-router');

Create MapRouter instance

var router = new MapRouter();

Attach the router to Express

app.use(router.middleware());

Add a new Route

router.register(method, path, handler)

Where

• method is the method to use or 'ALL' for matching all methods
• path is the path to the route (eg. '/path/to/handler')
• handler is the route handler

Example

var express = require('express');
var app = express();
var MapRouter = require('map-router');
var router = new MapRouter();

app.use(router.middleware());

router.register('GET', '/', function(req, res){
    res.send('hello world');
});

Alternatively you can register handlers with shorthand wrappers where method is the function name:

router.get('/', function(req, res){
    res.send('hello world');
});

Remove a Route

router.unregister(method, path)

Where

• method is the method to use or 'ALL' for matching all methods
• path is the path to the route (eg. '/path/to/handler')

Find a Route for a Path

If you are not using the Express compatible middleware but want to do your own routing, you can do this with

var handler = router.route(method, path)

Where

• method is the method to use or 'ALL' for matching all methods
• path is the path to the route (eg. '/path/to/handler')
• handler is the resolved handler function or false if the route was not found
