Binding to port

[jakeboyles]

I used the deploy to heroku button and am getting a problem with it not being able to bind to port. Am I missing something?

[jakeboyles]

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

Hi jakeboyles - I don't think it should bind to a port - it doesn't provide a web interface.

[jakeboyles]

I didnt think so either but for some reason its crashing my app on heroku

[kmoe]

Ah I had this - are you using a free dyno?

[kmoe]

I think there's a problem with Heroku where free dynos for nodejs apps can't be of the worker type.

[kmoe]

Thanks for bringing this up - I will investigate now.

[jakeboyles]

Yeah im using the free dyno. I was just going to wrap an express server around it and keep hitting the route with pingdom...

[kmoe]

@jakeboyles yeah I actually considered doing that before I upgraded to a hobby dyno (which I was going to do anyway) - seems wasteful but it genuinely seems to be a Heroku limitation/bug.

[kmoe]

If you initialise an express server you won't need to pingdom though

[kmoe]

Just having it listening is enough

[jakeboyles]

I figured out what to do.

[jakeboyles]

That solved it. So you can use the free dyno you just need to switch your worker.

[kmoe]

Interesting, I didn't have the option to do that when I tried - but I'd accidentally initialised the Procfile with only a web worker defined so maybe it 'stuck' that way.

[kmoe]

Thank you very much for your solution - I'll add it to the README.

[chris-j-major]

If it's non-intuitive, perhaps we could put an small express server there - we could even serve up stats from it...

[kmoe]

@chris-j-major that's a good extension, especially if paired with a nice frontend
you could even put Niantic server status there!

[kmoe]

@jakeboyles let me know if it works now this is resolved!

[jakeboyles]

Yeah, its working fine now. I think ill still hit the sleeping issue though.

[jakeboyles]

Unless the constant polling of the api solves that, so it might not sleep...

[kmoe]

Yeah, I expect you'll just end up using up your free dyno hours while the app is running.
