Server Script Debug Panel

Run the active widget's server.js on demand and see logs, UI messages, errors, timing and a query profile — re-runs use your unsaved edits.

SN Widget: Debug Server Script (or the 🐞 button in the Control Panel, or the editor right-click menu) opens a dedicated panel that runs the active widget's server.js and shows, for each run:

Logs, UI messages, errors, metrics and the query profile

Logs — gs.info / warn / error / log, color-coded by level
UI messages — gs.addInfoMessage / addErrorMessage
Errors — message and a formatted stack trace
Metrics — execution time, query count and number of data keys produced, plus a live/offline badge
Queries (Performance Profiler) — an expandable list of every GlideRecord/GlideAggregate operation: table, operation (query/get/aggregate/dot-walk), time in ms and rows returned, sorted slowest-first — so you can spot the table that's costing you

It keeps a history of the last 20 executions (newest first; runs with errors expand automatically). The "Re-run server script" button re-executes immediately using the current editor content — no save required, so you can iterate on server logic and watch the output without touching the live preview.

Slow-render alert

When a render takes longer than snWidgetKit.perfAlertThresholdMs (default 1000 ms; 0 disables), the run gets a SLOW badge and a warning toast appears (e.g. "rendered in 1240ms (37 queries) — above your 1000ms threshold"). It fires only on the manual Debug Server Script and Snapshot Widget Data runs — the live preview is never instrumented or interrupted.

Same data path as the preview

It uses live data when logged in, or offline data (fixtures.json) with your real options, user and messages. See Offline development.
