NetSuite SuiteScript Modules: Complete Guide to Every N/ Module

NetSuite SuiteScript 2.x is built around a powerful modular API system. Each module (prefixed with N/) handles a specific area of functionality — from working with records and running searches, to sending emails, making HTTP requests, and leveraging generative AI. This hub page is your complete reference for every NetSuite SuiteScript module, with a dedicated guide for each one.

Whether you are a beginner just starting with SuiteScript or an experienced developer looking for a quick reference, use the module index below to jump straight to the guide you need.

How NetSuite Modules Work

In SuiteScript 2.x, all functionality is encapsulated in modules that you load explicitly using AMD-style define() or require(). You only load the modules your script needs, which keeps governance usage low and your code organized. Each module has a unique N/ path (e.g., N/record, N/search, N/email) that you reference in your define array.

/**
 * @NApiVersion 2.1
 * @NScriptType UserEventScript
 */
define(['N/record', 'N/search', 'N/email', 'N/log'], (record, search, email, log) => {
    const afterSubmit = (context) => {
        log.debug({ title: 'Script triggered', details: context.type });
    };
    return { afterSubmit };
});
