How to split Node.js files in several files

Question

I have this code:

var express = require(\"express\");
var app     = express();
var path    = require(\"path\");

app.use(express.static(__dirname + \'/public         


        

Answer 1

your test.js should look something like:

var express = require('express');
var router = express.Router();

router.get('/test', function (req, res) {
  res.json(200, {'test': 'it works!'});
});

module.exports = router;

and the app.js (assuming other is some other route defined similarly to test.js):

var test = require("./routes/test.js");
var other = require("./routes/other.js");
...
//all your code for creating app 
...
app.use('/test', test);
app.use('/other', other);

Answer 2

You can define your routes in different files say test-routes.js like this:

module.exports = function (app) {
    app.get('/test', function(req, res) {
        res.json(200, {'test': 'it works!'})
    })
}

Now in your main file say server.js you can import your route file like this:

var express = require("express");
var app     = express();
var path    = require("path");

app.use(express.static(__dirname + '/public'));

app.get('/',function(req,res){
  res.sendFile(path.join(__dirname+'/views/index.html'));
  res.set('Access-Control-Allow-Origin', '*');
}).listen(3000);

console.log("Running at Port 3000");

// import your routes
require('./test-routes.js')(app);
