ember-quine

A quine is a computer program which takes no input and produces a copy of its own source code as its only output. ~ Quine (computing) - Wikipedia

Ember Quine is an Ember addon that enables an Ember app to be self downloaded as a single HTML file that runs offline (via the file:// URI).

This is best understood through demonstration. Vist the live example and play with it.

Compatibility

• Ember.js v3.4 or above
• Ember CLI v2.13 or above
• Node.js v8 or above

Installation

ember install ember-quine

By default all JS and CSS assets are compiled into the final index.html file. To disabled this (for development purposes) add the following to your config/environment.js:

ENV['ember-quine'] = { enabled: false };

Usage

This addon provides a quine service which exposes methods to download the app and load/save/remove data from the document storage mechanism.

Downloading the Quine App

Use the download() method to have the browser download a copy of the current running quine.

import Component from '@ember/component';
import { inject as service } from '@ember/service';

export default Component.extend({
  quine: service(),

  actions: {
    download(filename) {
      this.quine.download(filename);
    }
  }
});

This works by reading the HTML nodes (head and body) and capturing their innerHTML. It then constructs a new HTML document with string concatenation. It then builds a new tag with its href set to the constructed HTML. It adds the tag to the document, triggers a click action, and then removes the element.

quine.download(filename)

Initiates a download of the quine. It will reset quine.isDirty to false.
