Error When Conditionally Loading Custom Modules in SuiteScript

edited Jun 2, 2025 2:40PM in Ask A Guru 2 comments

Hello everyone!

I am working to optimize the performance of User Event Scripts applied to transactions, written in SuiteScript 2.1. During my debugging, I discovered that significant delays occur when my script loads certain Custom Modules, which are also written in SuiteScript 2.1 and function as libraries. To enhance performance, I want to load these Custom Modules only when they are essential.

Here's how I tried to conditionally load the modules based on examples from other forums:

if (formScriptId === 'custform_test') {
   require(['../../path_to_lib/lib'], (lib) => {
     lib.beforeSubmit(context, formScriptId);
   });
}

Alternatively:

if (formScriptId === 'custform_test') {
  const lib = require('../../path_to_lib/lib');
  lib.beforeSubmit(context, formScriptId);
}

Howdy, Stranger!
