Heroku Setup

• Delete package-json.lock as Heroku will install all dependencies.

• Add the default Node.js build-package in Heroku.

• Add all the Environment Variables typically added in .env.

• Add PORT as an additional Environment Variable.

• Add:

  app = express();
  app.listen(process.env.PORT);

to enable dynamic ports, otherwise it will timeout after 60 seconds due to a missing binding.

• Add:

  "start": "node index.js"

to the start-script.

• Add: express to dependencies in package.json
