Build Status npm npm

Module that updates source content for the desktop application translationCore.


Use the separate helper files (as best you can) for each story.

Some functionality will most likely have to change in the main index as well, but try to keep as much logic as possible in individual helpers.

Parsers can expect the catalog to be fetched before their method is called. It will be under the catalog property of the Updater object

Please try and cleary define your input and output parameter structures so to make collaboration easier

Check __tests__/fixtures/catalog.json for example metadata return from DCS


To use this module you must first create a new instance of the object. i.e.

import updater from 'tc-source-content-updater';
const Updater = new updater();

const updater = require('tc-source-content-updater').default;
const Updater = new updater();

Note: In order to limit the amount of API calls the door43 repo, the Updater object uses the same catalog resource throughout its lifetime, without having to continuosly do requests to door43 API on each function call.


  1. Create instance
  2. Fetch latest resources
  3. Download the resources that are not updated
