The centralindex Node.js module is an NPM module that allows Node.js developers to start using the Central Index API with minimal code. The Central Index is a global data exchange, with a simple REST/JSON api.

What do I need before I start?

Hello World

You'll need to install the centralindex module using

  npm install centralindex

Then your first script could look something like:

  // load the centralindex npm module
  var ci = require('centralindex');
  // configure your api key
  ci.setAPIKey('<insert api key here>');
  // pull a known entity by its unique entity_id
  ci.getEntity('379236608286720', function(error,body) {
    if(!err) {
    } else {
      console.log("Something went wrong");

You'll find further examples in the "examples" subdirectory.
