node.js (express framework): require and post

app.js:

var app = express();

require('./other_file.js')(app);

other_file.js:

app.post('/test', function(req, res) {
    console.log(true);
});

result: app is not defined.

How to use express methods in require file?

Thanks in advance.

You have to specifically export the member you want to expose with a require.

other_file.js should look like this

module.exports = function(app) {
  app.post('/test', function(req, res) {
    console.log(true);
  });
}

where module.exports is the member that is returned when the file is used with a require() statement.

Node itself borrows from the CommonJS module spec.

other_file.js should be something like that:

 module.exports = function(app) {
   app.post('/test', function(req, res) {
      console.log(true);
   });
 }

Longer story: when you require() a file you get back an object (the exports object). If you want to get back a function you need to make your function replace the exports object. To achieve that you need to assign your function to module.exports
