Library that encapsulates the (undocumented) IBM Cognos Analytics REST API.

You can use this to write tests, external clients or build tools for your Cognos environment. As the Cognos API is not official, things might break (badly) after Cognos upgrades.

npm install jcognos

Once the jcognos has been installed, you can include it in your projects as a CommonJS module

require("jcognos");

or as an ES2016 module

import getCognos from "jcognos";

Then get going like:

jcognos
  .getCognos("https://cognos.example.com/ibmcognos/", true)
  .then(function(lcognos) {
    lcognos.login("username", "password"); // Which also returns a promise
  });

If you want to run this module in your browser, this version does not support XSRF headers. It is (temporarily) broken. To use the module against Cognos Analytics 11.0.7 or later, follow these steps:

1. Open the Windows Services window and stop the IBM Cognos service.

2. Open the file installation_location\wlp\usr\servers\cognosserver\bootstrap.properties.

3. Add the following line:

   disableXSRFCheck=true

4. Save the file.

5. Restart the IBM Cognos service

You do not need to do this if you use jcognos in nodejs or in cordova.
