if-env

Simplify npm scripts with if-env ... && 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 [[ ${NODE_ENV} == \"production\" ]]; 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 NODE_ENV=production && npm run start:prod || npm start:dev",
  "start:dev": "webpack",
  "start:prod": "start-cluster"
}

Usage

1. Install

$ npm install if-env --save

2. Add to package.json

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