Heroku | Error R10 (Boot timeout) -> Web process failed to bind to $PORT (Solved)

[keshavmesta]

I encountered this issue today while I was trying get this boilerplate app running on Heorku.

Problem statement:
Travis-ci is successfully building & deploying the app on Heroku. However when I visit the site on Heroku, it just throws 'Application Error'.

Root cause:
So I figured out from heroku logs that this is something to do with custom port being set in package.json. This ticket also confirmed that.

Solution:
Delete the PORT parameter from production betterScripts in package.json so that it can be picked from process.env.PORT at runtime.
Should look like this after edit:
"start-prod": { "command": "node ./bin/server.js", "env": { "NODE_PATH": "./src", "NODE_ENV": "production", "APIPORT": 3030 }
