Ensure .env file exists before loading it

If you use the dotenv package and if there is no existing .env file in your deployment machine (could happen), things will fail.

It assumes that the file is there, so we have to write our code a little more carefully:

const dotenvPath = 'the/path/to/dotenv';

try {
  if (require('fs').statSync(dotenvPath).isFile()) {
      path: dotenvPath
} catch (ex) {
  console.log('.env does not exist');

Start http-server in background

http-server is a super convenient package if you just want to start a server locally, but if you want to use it in a PaaS, i.e. DigitalOcean you'd want it to run in the background or it'll get terminated with the SSG session.

  1. npm install -g http-server
  2. nohup http-server & or even better, with forever forever start -c "http-server" ./

Install a private NPM module securely

A private module has a package.json with "private": true property.

The easiest way will expose your password:

npm install --save git+

GitHub supports OAuth access to your own repositories, so:

  1. Sign in to
  2. Give the token a name, say 'Heroku deployment'
  3. Tick only the repo (Full control of private repositories) scope
  4. Use the generated token:
npm install --save git+https://<generated token>

The correct way to bump package version

  1. Commit all changes
  2. Run npm version minor (can be major or patch too)
  3. Run git push --tags
