Ember CLI Fastboot Addon

Provides facilities for writing code that works in both Fastboot and the browser.

Installation

ember install ember-cli-fastboot-addon

Usage

Addon Authors

Addons require a little more setup. If you're just using this in your app, you can move to the next step.

You need to use the Broccoli filter in your addon. In index.js:

module.exports = {
  name: 'my-addon',

  treeForAddon: function(tree) {
    var fastbootTree = require('ember-cli-fastboot-addon').fastbootTree;
    return this._super.treeForAddon.call(this, fastbootTree(tree));
  },

  treeForApp: function(tree) {
    var fastbootTree = require('ember-cli-fastboot-addon').fastbootTree;
    return fastbootTree(tree);
  }

}

General Usage

After running ember install, you should have a fastboot directory in either your app or your addon. Files in this fastboot directory will be included when running ember fastboot:build or ember fastboot:server, but no other time. Do not rely on code in fastboot to run in the browser build. Files in fastboot will NOT be included in the normal browser build.

For example, you may have an addon that runs in both node and the browser. Here's the browser code:

// addon/get-json.js

import Ember from 'ember';

export default function getJSON(url) {
  return Ember.$.getJSON(url);
}

Here's how someone would require that module:

// app/routes/application.js
import Ember from 'ember';
import getJSON from 'my-cool-ajax-addon/get-json';

export default Ember.Route.extend({
  model() {
    return getJSON('https://fivetanley.cloudant.com/docs');
  }
});

This code however, won't run in node due to jQuery's getJSON method requiring XMLHttpRequest, which is not available in node. We can write a addon/fastboot/get-json.js file that requires a node library to do the same thing:

// addon/fastboot/get-json.js

import {require} from 'ember-cli-fastboot-addon';

export default function(url) {
  // https://github.com/mzabriskie/axios
  const axios = require('axios');
  return axios({
    url: url,
    responseType: 'json'
  });
}

With this method, you don't have to change your app code! Your import statements remain the same.

Requiring node modules from NPM

You need to import require from ember-cli-fastboot-addon like this:

import {require} from 'ember-cli-fastboot-addon';

Then you can use require like you would in Node/Browserify/Webpack.

But I want to use NPM Modules in the browser app too!

You should definitely take a look at ember-browserify.

How does this work?

At build time, this addon checks for the presence of the EMBER_CLI_FASTBOOT environment variable. This will be set by ember-cli-fastboot.

Next, it looks at the addon (if this is an addon) and app directories. If there is a fastboot folder, it overwrites the files that would normally run in the browser with files from the fastboot folder.

If you had addon/index.js and addon/fastboot/index.js, the contents of addon/fastboot/index.js would appear as the index file instead in fastboot builds only. Otherwise, the normal addon/index.js file would be used instead.
