Simplify npm scripts with if-env-defined ... && npm run this || npm run that

Suppose you want to simplify development and be able to run npm start in all environments & run the correct scripts.

Your package.json might look like this:

"scripts": {
  "start": "if [[ -z ${NODE_ENV} ]]; then npm run start:prod; else npm run start:dev; fi",
  "start:dev": "webpack",
  "start:prod": "start-cluster"
}

The problem is, this doesn't work in all environments.

Instead, you can write:

"scripts": {
  "start": "if-env-defined NODE_ENV && npm run start:prod || npm run start:dev",
  "start:dev": "webpack",
  "start:prod": "start-cluster"
}

Usage

1. Install

$ npm install if-env-defined --save

2. Add to package.json

"scripts": {
  "start": "if-env-defined SOME_ENV_VAR=some_val ANOTHER_ENV_VAR=another_val && npm run this || npm run that"
}
