Compile Yahoo! Pipes to Javascript (Node.js)

Design

This tool lets you import Yahoo! Pipes and run them on any machine with Node.js.

The pipe is converted to a javascript file, called decider.js, which controls the execution logic of the workflow.

Each Yahoo module is coded as a separate Javascript module.

• The pipe can be executed localy through a simple run engine (called by the generated run.js)
• or executed on Amazon SimpleWorkflow (SWF)
• The rsulting modules can be used for other Amazon SWF projects through the aws-swf library

Installation

$ [sudo] npm install -g pipes2js

Usage

Import the pipe :

$ pipes2js xOE_1Z8C3RGmkQrul7okhQ

This will create a pipes/xOE_1Z8C3RGmkQrul7okhQ/ directory, which contains an npm package. The resulting package depends on the pipes2js package. Let's install it :

$ cd pipes/xOE_1Z8C3RGmkQrul7okhQ/
$ npm install .

You can then run it :

$ node run.js
