SuiteCommerce Developer: SuiteScript and Backend Customization

SuiteScript and Backend Customization

This domain tests the backend behind a SuiteCommerce storefront: SuiteScript 2.x scripts that feed the front end or react to shopper actions, and how to keep them inside governance limits.

Rules that carry marks

• Custom storefront logic is exposed through SuiteScript endpoints (RESTlets, or endpoints served by an SSP application) and called from the front end's service layer. The script deployment's audience and role decide whether an anonymous shopper can reach it.
• Anonymous shoppers run as the shopping role, so an endpoint that works for you in the NetSuite UI can still fail in the browser. Use "Available without Login" only deliberately, and test logged out.
• Prefer a single search with filters over per-item record.load; index results into a map instead of loading records in a loop.
• Use N/cache for reference data that rarely changes, N/log (not nlapiLogExecution) for diagnostics, and getRemainingUsage() when a loop can grow.

Worked example

A product-detail RESTlet returns specs and slows down as the catalog grows. The code loads the item record, then each related item record, inside the loop. Reasoning: per-iteration loads burn governance and round trips. Fix: one N/search over the related items with the needed columns, index results into an object keyed by internal id, assemble the response in memory, and cache the payload with a short TTL keyed by item id. The call becomes one search plus one cache read.

Traps

• Copying SuiteScript 1.0 nlapi* calls into an SCA module; 2.x modules use define and N/ modules.
• Scripts that fight SuiteCommerce's own pricing during checkout recalculation.
• Running bulk Map/Reduce or scheduled work during peak storefront hours instead of off-hours.
