Ember-cli-ifa

Inject fingerprinted assetMap.json file into your app and provide initializer, service, and helper to dynamically reference fingerprinted assets.

Installation

ember install ember-cli-ifa

Configuration

Enable addon in environment.js for specific environment.

module.exports = function(environment) {
  var ENV = {
    ...
    ifa: {
      enabled: true
    }
    ...
  };

Configure fingerprinting in ember-cli-build.js. Refer to the documentation of ember-cli for asset-compilation

fingerprint: {
  enabled: true, // set to true only in required environments
  generateAssetMap: true,
  fingerprintAssetMap: true
}

Usage

asset-map helper

If name is tomster-under-construction:

<img src={{asset-map (concat "assets/" name ".png")}} />

then it will generate something like assets/tomster-under-construction-da524c8bc9283f759ae640b68db81f24.png base on assetMap.json.

asset-map service

import Component from 'ember-component';
import service from 'ember-service/inject';

export default Component.extend({
  assetMap: service('asset-map'),

  key: null, // key passed as 'tomster-under-construction'

  // result will be assets/tomster-under-construction-da524c8bc9283f759ae640b68db81f24.png
  image: computed('key', function() {
    return this.get('assetMap').resolve(`assets/${this.get('key')}.png`);
  })
});

Storing assets in a sub-directory

If prepend option is added in fingerprint configuration block, it will be prepended into generated asset path in the index.html.

// ember-cli-build.js
// ...
var app = new EmberApp(defaults, {
  fingerprint: {
    prepend: '/blog/'
  }
});

/blog will be prepended to the assetMap file path in the index.html.
