How to set default path (route prefix) in express?

Question

Instead of doing path + '..' foreach route - how can I prefix every route?

My route shall be

/api/v1/user 

What I don't want to do

var path = '/api/v1'; app.use(path + '/user', user); 

What I want to do

 var app = express();  app.setPath('/api/v1');  app.use(..); 

Answer 1

Using Express 4 you can use Router

var router = express.Router(); router.use('/user', user);  app.use('/api/v1', router); 

Answer 2

If you are using Express 4 Router you can use route() method to set the path and create a chainable route handler

app.route('/book')   .get(function (req, res) {     res.send('Get a random book')   })   .post(function (req, res) {     res.send('Add a book')   })   .put(function (req, res) {     res.send('Update the book')   });
