Heroku Node.js Error R10 (Boot timeout) -> Web process failed to bind to $PORT within 60 seconds of launch

Question

I found a dozen solutions for Express powered apps with setting port to listen on. But I have an app that doesn't use Express and doesn't in fact listens anything. And after 60 seconds of it successfully running I get a Error R10 (Boot timeout) -> Web process failed to bind to $PORT within 60 seconds of launch message. How I can get around it? Thanks.

Answer 1

After lots of googling I decided to npm install express and add

var express = require('express');
var app     = express();

app.set('port', (process.env.PORT || 5000));

//For avoidong Heroku $PORT error
app.get('/', function(request, response) {
    var result = 'App is running'
    response.send(result);
}).listen(app.get('port'), function() {
    console.log('App is running, server is listening on port ', app.get('port'));
});

This fixed the error, even though I don't like adding express just to avoid one error. If someone finds a better solution, please let me know.

Answer 2

If your app doesn't listen any port then you should use another type of app in you Procfile, I mean in Procfile you have:

web: node app.js

replace it with:

worker: node app.js

"web" type of application means that your app MUST listen some port

Answer 3

Another way would be changing the dynos from web (standard setting regardless of the settings in Procfile) to worker with these commands:

heroku ps:scale web=0
heroku ps:scale worker=1

Sometimes Heroku ignores settings in the Procfile.

I have the same issue:

Error R10 (Boot timeout) -> Web process failed to bind to $PORT within 60 seconds of launch

I tried many things.

The following works without using express:

http.createServer(onRequest).listen(process.env.PORT || 6000)

I also got the same the same problem: Error R10 (Boot timeout) -> Web process failed to bind to $PORT within 60 seconds of launch

flowing work in my pc windows 10 visual studio code

app.listen(process.env.PORT || 8080);

also added these three line in package.json

"worker": "node index.js", "start": "node index.js" "test": "node test.js"
