per-env

Clean up your package.json with per-NODE_ENV npm scripts.

Features

• Call npm stages based on NODE_ENV (defaults to development)

Changes from 1.x

• BREAKING Dropped support for per-env environment variables in package.json.
  This change was made to simplify the implementation and to avoid potential conflicts with other packages that set environment variables (dot-env, etc.).
• Added support for different script runners (bun, yarn, etc).
  Previously all scripts were run with npm, regardless of the runner used to run per-env.
• Added tests.

Example

{
  "scripts": {
    // If NODE_ENV is missing, defaults to "development".
    "build": "per-env",

    "build:development": "webpack -d --watch",
    "build:staging": "webpack -p",
    "build:production": "webpack -p",

    // Deployment won't work unless NODE_ENV=production is explicitly set.
    "deploy": "per-env",

    "predeploy:production": "docker build -t ${DOCKER_USER}/${DOCKER_PROJECT} .",
    "deploy:production": "docker push ${DOCKER_USER}/${DOCKER_PROJECT}",

    // "npm start" is _the_ command to start the server across all environments.
    "start": "per-env",

    "start:development": "npm run build:development",

    "prestart:production": "npm run build",
    "start:production": "start-cluster build/server/server.js",

    "prestart:staging": "npm run build",
    "start:staging": "start-cluster build/server/server.js",
  }
}
