app: address some console errors

[fabiosantoscode]

The errors about the client pinging but the page not existing can only occur on the dev server. It shouldn't be running since npm start is setting the NODE_ENV to production, but still I added the NODE_ENV environment variable to app.json just to make sure heroku isn't running server.js raw.

Updated yarn.lock

So, it looks like we don't need this right? Could you check if Heroku sets env properly?

[fabiosantoscode]

@shcheklein I did some digging yesterday before opening this PR, and I couldn't find any literature on Heroku which said it would run server.js raw, my setting the NODE_ENV variable is more like a last ditch effort.

@fabiosantoscode https://devcenter.heroku.com/changelog-items/688 ?

[fabiosantoscode]

Didn't see that one! I'll revert that part then.

[shcheklein]

@fabiosantoscode then we don't have anything else left on this PR, right? If ticket is not reproducible can we close it @jorgeorpinel ?

[fabiosantoscode]

Just the yarn.lock update @shcheklein

[shcheklein]

Do you know why does it remove so much stuff in yarn? Also let's remove the "Fixes ..." from the description and comment in the issue that you was not able to reproduce it?

[fabiosantoscode]

That's right, it shouldn't close the issue at all. My bad.

[fabiosantoscode]

No idea why it removes so many packages. Someone might have done some spring cleaning on their dependencies.

[jorgeorpinel]

We probably didn't run an update in a while.
