Nodeschnaps is a node.js compatibility layer for Java Javscript engines like Rhino. The main inspiration is to run ETL transformation with the same code we use in node.js to save development time.

Features

We work hard to implement the full API of node.js. So you could load Nodeschnaps into your Rhino environment and use your node.js code without restrictions. Take a look at the current development status to get a overview of what we done so far.

Supported Platforms

• Rhino JS
  • Pentaho Data-Integration (Kettle)

We plan to support the following platforms in the next time:

• Nashorn

Installation

npm install nodeschnaps

Testing

Install dev dependencies:

npm install

Run tests with rhinojs:

make test

Run tests with nodejs:

make testNode

Configuration

Environment Variables

NODESCHNAPS_PATH

Path to search for modules/files (Last must be the nodeschnaps lib folder).

NODESCHNAPS_MODIFIER

A path to a module, what will be loaded at the start to modify the environment.

Rhino JS

load('../loader.js');

NodeJS();

Pentaho Data-Integration (Kettle)

Load on Job (JavaScript):

new Function(
    org.apache.commons.io.FileUtils.readFileToString(
      new java.io.File(parent_job.getVariable('NODESCHNAPS_LOADER_FILE'))
    )
)();

NodeJS();

Load on Transformation (Modified Java Script Value):

LoadScriptFile(getEnvironmentVar('NODESCHNAPS_LOADER_FILE'));

NodeJS();

For a example look at: kitchen-stove

Coding

Start main loop

As callback:

NodeJS(function(){
    // Your code here ...
});

Or before:

// Your code here ...

NodeJS();
