Ares 2 Overview

Updated: 2012-08-17

Ares 2 is a browser-based code editor and UI designer for developing Enyo 2 applications. Although Ares is still a work in progress, we have reached the point where we are opening the repo and will do further development in the open, so we encourage you to follow our progress and give us feedback as we push Ares forward.

Basic architecture

The Ares project architecture is divided into several main pieces:

  • Ares - The front-end designer/editor web application, with the following main components:
    • Harmonia - File system layer
    • Phobos - Document management
    • Deimos - Visual designer
  • Hermes Components - Pluggable server-side components that provide interfaces to Ares clients for cloud-based services such as file storage and build services. We're leveraging node.js, but Hermes components can use any server-side tech.

Current status

Here are the main features you can start looking at today:

  • De-centralized file storage
    • Ares currently connects toto a "filesystem" component, to edit local files
    • We plan to add Hermes components for things Dropbox (implemented but not tested), FTP and in the future
    • Key goals with this approach are to avoid forcing users to store files and/or credentials on Ares servers and allow freedom to choose the preferred storage location, whether cloud or local.
  • Code editor
    • Ares integrates the Ace (Cloud9) code editor for code editing
  • Code intelligence
    • Upon opening/editing a JavaScript file, Ares will parse the file and display a semantic outline of the code in the right-hand panel (for purposes of demonstrating parser)
    • In the future, this will be used for advanced features such as code-completion, context-sensitive documentation, etc.
  • UI designer for drag and drop UI editing
    • The UI designer is hooked up to the editor in read-only mode currently.

Note: The current Dropbox interface was implemented with an authentication mechanism that has since been deprecated by Dropbox and for which API keys are no longer available, so most users will not be able to run their own Hermes Dropbox component at the moment. However, those wishing to test drive the functionality above can open ares/index.html which points to a temporary hosted version of the Dropbox Hermes component using a valid API key. We will be migrating the Dropbox authentication mechanism to the currently recommended scheme. Note there is not yet a publicly hosted version of Ares.

Future plans

The following features are in the works, and you should see them added as we move forward:

  • Round-trip editing in the code editor and the designer
  • Code completion and context-sensitive documentation
  • Additional Hermes components to extend the local and cloud file storage options
  • ... and more!


Install Node.js 0.8 or later, preferably from the Official Download Page.

Get the source at the proper location: For Ares to run, it expects the enyo and lib folders (including onyx, layout, and extra) from the 2.0b5 SDK (or later) from Github to be present next to ares-project, as follows:

    * ares-project
    * enyo    
    * lib
        * onyx
        * layout
        * extra


You have two options:

  1. Use the IDE server (recommended)
  2. Configure & start sub-servers manually & open ares/index.html as a local file from the browser.

Served IDE

Configure the root of your local file-system access ide.json.

% vi ide.json
        "name":"Local Files (home)",
        "command":"@NODE@", "params":[
            "hermes/filesystem/index.js", "0", "@HOME@"
        "debug": false

Start the IDE server:

% node ide.js
ARES IDE is now running at <> Press CTRL + C to shutdown

Connect to the IDE using Google Chrome or Chromium. The default URL is

% open -a "Chromium"

Debugging: You cann add --debug or --debug-brk to the node command-line in ide.json if you want to troubleshoot the service providers, or directly on the main node command line to to troubleshoot the main IDE server. Then start node-inspector as usual.

Manual IDE

Start the file server:

$ node ares-project/hermes/filesystem/index.js 9010 hermes/filesystem/root

Debugging: The following sequence (to be run in separated terminals) opens the ARES local file server in debug-mode using node-inspector.

$ node --debug ares-project/hermes/filesystem/index.js 9010 hermes/filesystem/root

...then start node-inspector & the browser windows from a separated terminal:

$ open -a Chromium http://localhost:9010/ide/ares/index.html
$ node-inspector &
$ open -a Chromium http://localhost:8080/debug?port=5858
