Ember CLI Dotenv

This is a fork of fivetanley/ember-cli-dotenv with PR#6 by github.com/gniquil that I created just to ease my deployment via NPM. All credit goes to the original authors. This repo is not intended for production use, just learning from it.

Installation

npm install --save-dev ember-cli-dotenv

What is Ember CLI Dotenv?

This addon allows you to write environment variables in a .env file and expose them to your Ember app through the built-in config/environment.js that you can import in your app. For example, you might be building an app with Dropbox and don’t want to check your key into the repo. Put a .env file in the root of your repository:

DROPBOX_KEY=YOURKEYGOESHERE

Next, put some configuration in your Brocfile. Starting in 0.2.0, client side keys must be explicitly allowed:

// Brocfile.js

var app = new EmberApp({
  dotEnv: {
    clientAllowedKeys: ['DROPBOX_KEY']
  }
});

// pre-generated config from ember-cli
module.exports = app.toTree();

All keys in .env are currently injected into node’s process.env. These will be available in your config/environment.js file:

// config/environment.js
module.exports = function(environment){
  return {
    MY_OTHER_KEY: process.env.MY_OTHER_KEY
  }
};

You can then use the node process environment variables in other ember-cli-addons, such as express middleware or other servers/tasks.

Security: environment variables in config/environment.js are never filtered unlike using .env and clientAllowedKeys. Remember to use the environment variable passed into your config function to filter out secrets for production usage.

then, you can access the environment variables anywhere in your app like you usually would.

import ENV from "my-app/config/environment";

console.log(ENV.DROPBOX_KEY); // logs YOURKEYGOESHERE

You can read more about dotenv files on their dotenv repository.

All the work is done by ember-cli and dotenv. Thanks ember-cli team and dotenv authors and maintainers! Thanks Brandon Keepers for the original dotenv ruby implementation.

Multiple Environments

Sometime people may want to use different .env file than the one in project root. This can be configured as below:

// Brocfile.js

var app = new EmberApp({
  dotEnv: {
    clientAllowedKeys: ['DROPBOX_KEY'],
    path: './path/to/.env'
  }
});

// pre-generated config from ember-cli
module.exports = app.toTree();

In addition, you may also customize for different environments:

// Brocfile.js

var app = new EmberApp({
  dotEnv: {
    clientAllowedKeys: ['DROPBOX_KEY'],
    path: {
      development: './path/to/.env',
      test: './path/to/.env.test',
      production: './path/to/.env.production'
    }
  }
});

// pre-generated config from ember-cli
module.exports = app.toTree();

With the above, if you run ember build --environment production, the file .env.production will be used instead.
