penv

A package.json environment customizer

Sometimes we need a different package.json properties for our different environments like production, staging and development. (Ex: jitsu deploys)

With penv you can customize your package.json file with properties defined inside an environments.json file.

Installation

$ npm install -g penv

Example

package.json

Create your package.json file

{
  "name": "app",
  "subdomain": "myapp",
  "scripts": {
    "start": "node app.js"
  },
  "version": "0.0.1",
  "engines": {
    "node": "0.8.x"
  }
}

environments.json

Create your environments.json file with the customized properties

{
  "staging": {
    "name": "app-staging",
    "subdomain": "myapp-staging"
  }
}

Then run

$ penv staging

And you will have a customized package.json like the following:

customized package.json

{
  "name": "app-staging",
  "subdomain": "myapp-staging",
  "scripts": {
    "start": "node app.js"
  },
  "version": "0.0.1",
  "engines": {
    "node": "0.8.x"
  },
  "env": {
    "NODE_ENV": "staging"
  }
}

Restore Original

The original package.json file will be renamed to .package.json. You can restore your original package.json by running

$ penv base
