Queen-Remote Build Status

Write Queen applications which run Queen Scripts on a remote Queen Server.

This library provides the tooling required to write Queen applications which can utilize a remote Queen Server as if it were local. This is particularly useful in creating thin-client applications which harness the full power of Queen. This package also comes with the queen-remote executable, allowing you to execute Queen Scripts remotely through a remote Queen Server.

Running Queen Scripts Remotely

  1. Install queen-remote: npm install -g queen-remote
  2. Run your script queen-remote -h queen.turn.com:9200 http://queenjs.com/server-example.js

This will establish a connection to the Queen Server running at queen.turn.com:9200, and execute the server-example.js Queen Script on it with all of it's captured browsers.

Command line Options

-h [host] (also --host) port 9200 on the current IP address by default

The host of the Queen Server to connect to.

// Example
// Starts queen-remote and connect to a Queen Server running at queen.turn.com:9283
queen-remote -h queen.turn.com:9283

-p [host] (also --proxy)

Sets up this queen-remote instance to pretend to be a Queen Server which other queen-remote applications can connect to. It will act as a proxy to the real Queen Server and relay communications accordingly.

// Example
// Starts queen-remote and connect to a Queen Server running at queen.turn.com:9283
// then starts listening on localhost:9122 for other queen-remote instances to connect to this server
// when they do, it will relay their requests to queen.turn.com:9283
queen-remote -h queen.turn.com:9283 -p localhost:9122

[path] queenConfig.js by default

This can either be a local file path, or a URL. The file can either be a Queen config file, or a Queen script.

// Example
// These examples all try to connect to a Queen Server running on localhost:9200

// Starts Queen Remote with configuration defined in queenConfig.js 
// if it exists in the current directory, or defaults otherwise
queen-remote -h localhost:9200

// Starts Queen Remote with a configuration file that is not named queenConfig.js
queen-remote -h localhost:9200 my-config-file.js

// Starts Queen Remote with default options and executes the my-queen-script.js when Queen is ready
queen-remote -h localhost:9200 my-queen-script.js

If the file is a Queen config file, it will be used to configure this queen instance.

If the file is a Queen server-side script, queen will disable it's remote server and execute the server-side script.

-v or --verbose

Enable debug logging.

-q or --quiet

Supress logging.

Programmatic API

Importing this module via require('queen-remote') will give you an object with the following properties.

  • client - This is an object which implements the Queen module API and takes an additional "host" variable in it's options object -- the host of the remote server. So long as you give it the host, you can do all the things you can do with the a real Queen Server API with it.
  • server - A RPC server that the Queen Server uses to accept connections from queen-remote clients.
  • runner - The runner function that both Queen Server and Queen Remote uses to start up via their command line interfaces.
