Package Exports

upc-database

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (upc-database) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

upc-database.js

Node module for accessing the UPC Database (upcdatabase.org)

Install

npm install upc-database

Getting started

Obtain an API key from ucpdatabase.org

Require the module into your code:

var UPC = require('upc-database');

Add your API key

var UPC = require('upc-database');
var upc = new UPC('api key here');

Make a request

var UPC = require('upc-database');
var upc = new UPC('api key here');

upc.json('0111222333446', function(response){
  if(!response.serverError && response.valid){
    // successful request
    console.dir(response.upc);
  } else if(!response.serverError && !response.valid){
    // successful request but invalid API request (ex: Invalid UPC code given)
    console.log(response.reason);
  } else {
    // server error (404, 403, etc.)
    console.log('server error'); 
  }
});

Output

{ statusCode: 200,
  serverError: false,
  valid: true,
  upc:
   { number: '0111222333446',
     itemname: 'UPC Database Testing Code',
     alias: 'Testing Code',
     description: 'http://upcdatabase.org/code/0111222333446',
     avg_price: '123.45',
     rate_up: '12',
     rate_down: '2' 
   } 
}

Or for XML

upc.xml('0111222333446', function(resp){
    if(!resp.serverError && resp.valid){
        console.dir(resp.upc);
    } else if(!resp.serverError && !resp.valid){
        console.log(resp.reason); 
    } else {
        console.log('server error');
    }
});
