This is an example of how to use concha to remotely control Deezer from the shell using the included deezer plugin:

You can create your own plugins too!

Install

npm install -g concha

Usage

1- First, start your concha server by running: concha

2- Open the bookmarklet install page by navigating to: http://localhost:7331/install

3- Drag and drop the bookmarklet link into your bookmarks bar for easy access.

4- Open any website and click on the bookmarklet you just addded. This will inject a concha client into the current page and it will connect to the concha server.

Now you're ready to start typing commands into the server's command line interface to remotely access your browser's console.

How it works

concha consists of the following components:

server: a webserver and a websocket; sends command and recives responses
server's cli: the server forwards commands typed in the console to the browser
bookmarklet installer: a static web page with a link to easily save the bookmarklet
bookmarklet: runs the injector on the currently open web page
injector: small js tool to load the concha client in the browser
client: the browser code which connects to the server; receives commands and sends responses

When you start concha a web server is loaded on port 7331 by default. This web server let's you access to the bookmarklet installer on http://localhost:7331/install. The server also opens a websocket for communication with clients. Once you use the injector on any web page it loads the concha client. The injector also uses the web server to load. The client connects to the server using the open websocket. Once client and server are connected thru the websocket you can start sending commands from the server's cli. Commands will run on the browser and responses will be shown on the shell.

Plugins

concha supports plugins! Right now there's only one plugin thought to be used on http://deezer.com. Plugins are the ideal way to add custom functionality for your complete enjoyment of concha. You can remotely control any website, sending and retrieving data from the console. You can even automate tasks if you like.

Plugins are in the src/plugins folder. They are enabled in the config file. For example, this enables the Deezer plugin:

  "plugins": [
    "deezer"
  ]

Autocomplete

concha also supports command auto complete ;) Each plugin can add its own commands for auto complete by creating a file with this format: [pluginName].autocomplete.js

As an example, this is the auto complete file for the Deezer plugin:

module.exports = [
  'play()',
  'pause()',
  'next()',
  'prev()',
  'mute()',
  'unmute()',
  'repeatOff()',
  'repeatAll()',
  'repeatOne()',
  'shuffleOn()',
  'shuffleOff()',
  'getAlbumTitle()',
  'getArtistName()',
  'getSongTitle()',
  'info()',
  'playFavorite()',
  'flow()'
