firebase-config: a command-line utility for working with firebase config files.

firebase-config is a utility that lets you manage different firebase config files for different environments. It uses the value of process.env.NODE_ENV to determine the appropriate firebase config file for that enviromnent and creates a firebase.json file that is a symlink to the firebase config file for that environment.

Installing globally:

Installation via npm. If you don't have npm yet:

 curl https://npmjs.org/install.sh | sh

Once you have npm:

 npm install firebase-config -g

This will install firebase-config globally so that it may be run from the command line.

Configuring with package.json:

firebase-config uses a special firebase-config field in the package.json to resolve locations of firebase config files. For example,

"firebase-config": {
  "output": "public/",
  "configs": {
    "development": "config/firebase-dev.json",
    "production": "config/firebase-prod.json"
  }
}

You can use the "output" field to tell firebase-config where to place the generated firebase.json file. This defaults to the directory containing package.json The "configs" field is a map of values of NODE_ENV to the firebase config files to use for each environment.

Usage:

Set NODE_ENV

• linux & mac: export NODE_ENV=production
• windows: set NODE_ENV=production

Run firebase-config from your project directory.
