Installation

npm install --save documentcloud

Usage

The client interface makes it possible to pass in your DocumentCloud username and password so you can do authenticated requests. While this is not required for some endpoints, your experience will likely be much better if you are authenticated.

// import the library
var DocumentCloudClient = require('documentcloud');

// create a client
var client = new DocumentClient('username', 'password');

// get to work!
client.documents.get('1659580-economic-analysis-of-the-south-pole-traverse', function (err, response) {
  if (err) throw err;

  console.log(response);
});

// {
//   "status_code": 200,
//   "response": {
//     "document": {
//       "id": "1659580-economic-analysis-of-the-south-pole-traverse",
//       "title": "Economic Analysis of the South Pole Traverse",
//       "access": "public",
//       "pages": 38,
//       ...
