route-prefix

add a prefix in front of a router

example

Suppose you have a router.js file:

var routes = require('routes');
 
module.exports = function () {
    var r = routes();
    r.addRoute('/', function (req, res) {
        res.end('oh hello\n');
    });
    r.addRoute('/robot', function (req, res) {
        res.end('beep boop\n');
    });
    return r;
};

Now you can mount that router at a prefix. In this case, the prefix is /xyz:

var http = require('http');
var prefix = require('../');
var router = prefix('/xyz', require('./router')());
 
var server = http.createServer(function (req, res) {
    var m = router.match(req.url);
    if (m) return m.fn(req, res, m);
    res.statusCode = 404;
    res.end('not found\n');
});
server.listen(5000);

methods

var prefix = require('route-prefix')

var prouter = prefix(pre, router)

Return a new router prouter that mounts the routes router at the prefix string pre.

The given router just needs to have a router.match(url) function that returns a falsy value when the route doesn't match. The routes package happens to supply that interface but you can use whatever module you want and the enumerable properties are copied from router to create the prouter copy.

install

With npm do:

npm install route-prefix
