Nodejs ./bin/www script not running on startup

node ./bin/www not working
express-generator es6
npm start not working
nodejs bin folder
express project structure
node js scaffolding
bin/www does not exist

I'm learning node.js. I setup node and express on my machine. Then I used express auto project generator to setup a basic project. I could see my localhost:3000 page. But then something happened and it suddenly stopped working (obviously im not sure what happend).

I tried debugging and adding some console statements. It turns out ./bin/www file which is supposed to run on start up (specified in package.json) is not getting executed at all.

If I just add these 2 lines of code from ./bin/www to my app.js file everything seems to work fine.

var port = (process.env.PORT || '3000');

So I think culprit is bin/www file but I'm not sure why it is not getting executed at all?

In my package.json file I have this

  "scripts": {
    "start": "node ./bin/www"

Let me know if I should be posting any other information that can be helpful.

Modify the scripts to:

"scripts": {
    "start": "node ./bin/www/app.js"

and then use the command npm start Hope that helps!

It seems that you have not started node server. Try adding following in app.js :

app.set('port', process.env.PORT || 3000);

var server = app.listen(app.get('port'), function () {
    console.log('server listening on port ' + server.address().port);

Now start your server using node app

Synology has a node.js package but that just installs the tools - it has no 'container' or any other support to drop files and have it run automagically.

After using npm start if the terminal shows >node ./bin/www than it means your server is already running. It will work just fine. Just manually paste: http://localhost:3000/ on your browser. You will get the braintree drop-in UI as expected.

Next time you need to fire up your app, just do this: npm start That's it. Now your startup is the same across all apps and you never have to think about any ridiculous mishmash of commands and flags.

  • how are you running app? using npm start or node app.js
  • by running command node app.js
  • what is the difference between those 2? I have never heard anything about npm start
  • If there is .bin/www in your applicaion that means you are using Express 4.0 . In case of Express 3.0 we need to run command 'node app.js' but in case of Express 4.0 we need to run command 'npm start' to run nodeJS application. So , here seems you are using Express 4.0, so run your application through 'npm start'
  • yes running npm start instead of node app.js worked, can you please explain why and what is the difference between the two?
  • npm start calls node to execute a file. You created app.js in ./bin/www folder. When you say node <directory>, the javascript file that you want to run MUST be named index.js, if you want to run the javascript file that is not named index.js, you have to run the file as node <file name>.
