How to add a custom environment for ember.js?

@ryleigh 

To add a custom environment for Ember.js, you can follow these steps:

1. Create a new environment file: First, create a new JavaScript file in the config folder of your Ember.js project. You can name this file as per your custom environment (e.g., config/environment-custom.js).
2. Define the custom environment settings: In the new environment file, define the settings specific to your custom environment. You can set configurations like API endpoints, feature flags, or any other environment-specific variables here.

Here is an example of how you can define a custom environment configuration:

// config/environment-custom.js

/* jshint node: true */

module.exports = function(environment) {
  var ENV = {
    modulePrefix: 'my-ember-app',
    environment: environment,
    rootURL: '/',
    locationType: 'auto',
    API_URL: 'https://api.custom.com'
  };

  return ENV;
};

1. Update Ember CLI build configuration: Next, update the ember-cli-build.js file in the root of your Ember.js project to include the custom environment settings. You can do this by modifying the app import statement to include the custom environment:

// ember-cli-build.js

const EmberApp = require('ember-cli/lib/broccoli/ember-app');

module.exports = function(defaults) {
  let app = new EmberApp(defaults, {
    environment: EmberApp.env(),
    // Import custom environment settings
    configPath: 'config/environment-custom.js'
  });

  return app.toTree();
};

1. Start Ember server with custom environment: Finally, you can start the Ember.js server with the custom environment settings by specifying the environment when running the ember serve command. For example, to run the server with the custom environment named custom:

1

ember serve --environment=custom

By following these steps, you can add a custom environment for your Ember.js project and configure it with specific settings for your development, staging, or production environments.
