nodejs require is not a function to js file

Question

I want to make a little chat app for learning and I created many js files which for separate like modular but I got some error.

this is my boot.js file

var app = require('express')();
var http = require('http').Server(app);
var io = require('socket.io')(http);
var admin = io.of('/app'),
 client = io.of('');
module.exports.app = app;
module.exports.http = http;
module.exports.io = io;

this is my routes.js file

module.exports = {
 start: function(app) {
 app.get('/', function(req, res) {
 res.sendFile(__dirname + '/index.html');
 });
 }
};

this is my chat.js

var boot = require('./boot');
require('./routes')(boot.app).start();
http.listen(3000, function(){
 console.log('listening on *:3000');
});

when i run the node i got this error

require('./routes')(boot.app).start();
 ^
TypeError: require(...) is not a function

how could I use the variables which in the boot.js to other js files?

help me please.

• Ayush Gupta: shouldn't it be require('./routes').start(boot.app);
• Nidhin David: Seems like you are doing too many things in a single line. require is not async. Make sure express is initialzed before you require it
• Hanik: works thank you so much :)

Answer 1

You are making a small mistake here. Below is the correct one.

require('./routes').start(boot.app);

routes module exports an object where you can call start and use that function.
