JavaScript Libraries - The Digital Platform Documentation Site

Skip to main content

The following JavaScript libraries are shipped with iCM and are available server-side to use in Forms and End Points.

The JavaScript libraries that come packaged with iCM are held in the API Server. They form a module system, similar to that of Node.js, with modules loaded using require('module_name'); which returns a JavaScript object.

We recommend loading all required modules at the top of the script that uses them, and to give the returned objects the same name as their respective modules, for example:

const axios = require('axios'); //loads the axios library

Once loaded these variables are then treated as namespaces for the modules. See the relevant documentation below for examples.

Only the libraries supplied by GOSS Interactive can be used in this way. It is not possible to add additional libraries to the API Server. The upgrade and patch process involves reinstalling the API Server so only the default libraries supplied with iCM will be present after such work. If there's a library you would like to see included, let us know!
