Restify Router

Build Status

This module allows you to define your routes using a Router interface that is identical to how routes are registered on a restify server. You can then apply the routes to a server instance.

Borrowing from the idea of Express router where you can organize routes by creating multiple routers and applying them to an express server, this component allows you to achieve a similar separation/grouping of route definitions.


$ npm install --save restify-router

Creating a router

A router object is an isolated instance of routes. The router interface matches the interface for adding routes to a restify server:

var Router = require('restify-router').Router;
var routerInstance = new  Router();
var restify = require('restify');
function respond(req, res, next) {
  res.send('hello ' +;
// add a route like you would on a restify server instance
routerInstance.get('/hello/:name', respond);
var server = restify.createServer();
// add all routes registered in the router to this server instance
server.listen(8080, function() {
  console.log('%s listening at %s',, server.url);

Why use it?

When your application starts to contain a lot of routes, you may want to group the definition of routes in separate files rather than registering every route in a single server bootstrap/creation file.

For example, if we have two sets of routes in our application:


  • GET /users
  • GET /users/:id


  • GET /posts
  • GET /posts/:id
var userRouter = require('./user.router'); // return a Router with only user route definitions
var postsRouter = require('./posts.router'); // return a Router with only posts route definitions
var restify = require('restify');
var server = restify.createServer();
// add user routes
// add posts routes
server.listen(8080, function() {
  console.log('%s listening at %s',, server.url);

Prefixing Routes

To prefix all routes, specify the prefix as the second argument to router.applyRoutes(server, prefix)

  • prefix must be a string or a regex



  • GET /admin/settings
  • GET /admin/controls
var Router = require('restify-router').Router;
var restify = require('restify');
function settings(req, res, next) {
function controls(req, res, next) {
var routerInstance = new Router();
// add a route like you would on a restify server instance
routerInstance.get('/settings', settings);
routerInstance.get('/controls', controls);
var server = restify.createServer();
// add all routes registered in the router to this server instance with uri prefix 'admin'
routerInstance.applyRoutes(server, '/admin');
server.listen(8080, function() {
  console.log('%s listening at %s',, server.url);

Nesting Routers

If you are familiar with Express style routers, you have the ability to nest routers under other routers to create a hierarchy of route definitions.

To nest routers use the .add method on a Router:

router.add(path, router);
  • path - a string or regexp path beginning with a forward slash (/)
    • All routes defined in the provided router will be prefixed with this path during registration
  • router - the router instance to nest

Example Usage

// routes/v1/auth.js
const router = new Router();"/register", function (req, res, next) {
 // do something with req.body
 res.send({status: 'success'});
 return next();
module.exports = router;
// routes/v1/routes.js
const router = new Router();
router.add("/auth", require("./auth"));
module.exports = router;
// routes/routes.js
const router = new Router();
router.add("/v1", require("./v1/routes"));
module.exports = router;

With the above router definition from routes/routes.js we can do the following call:

POST /v1/auth/register

This call is possible because we have nested routers two levels deep from the /v1 path.

Common Middleware

There may be times when you want to apply some common middleware to all routes registered with a router. For example, you may want some common authorization middleware for all routes under a specific router.

All middleware registered via .use will be applied before route level middleware.

To stay consistent with the restify server interface, the method on the Router is:

  • .use(middlewareFn, middlewareFn2, ...)
  • .use([middlewareFn, middlewareFn2, ...])

Note: Multiple calls to .use will result in aggregation of middleware, each successive call will append to the list of common middleware

Example Usage

var router = new Router();
// this will run before every route on this router
router.use(function (req, res, next) {
   if (req.query.role === 'admin') {
    return next();
   } else {
    return next(new errors.UnauthorizedError());
router.get('/hello', function (req, res, next) {
router.get('/test', function (req, res, next) {
// calling GET /hello  runs use middle ware first and then the routes middleware
