Description from store
SN Code Analyzer is a lightweight Chrome extension that lives in your browser and keeps your ServiceNow scripts clean, fast, and production-ready. Open any ServiceNow record with script content and get an instant quality score (0–100) plus clear, prioritized fixes based on industry best practices.
What it does
- Auto-detects script type from the page URL (Client Script, Business Rule, UI Action, Script Include, UI Page/Jelly, Portal Widget, Scheduled/Fix Script, ACL, Transform Script…).
- Scores your code against 50+ best-practice checks (performance, safety, readability, maintainability) and shows a concise, actionable report.
One-click AI improvement (optional)
Hit Improve with AI to get a clean, corrected version of your script that respects the right runtime:
- No gs.*/GlideRecord on the client, ever.
- Server code uses GlideRecord/GlideAggregate correctly, avoids recursion in Business Rules, adds setLimit(1), etc.
- Client code uses g_form.isLoading() guards, newValue !== oldValue checks, and async GlideAjax (never getXMLWait).
- Copy the improved code with one click.
How it works (in 3 steps)
1. Open a ServiceNow script record in your instance.
2. Click the extension and press Analyze → see your score and top fixes.
3. (Optional) Click Improve with AI → paste the cleaned-up script back into ServiceNow.
What gets scored
- Client scripting: proper guards, async server calls via GlideAjax, no client-side GlideRecord, correct setValue(field, sys_id, display) usage.
- Business Rules: correct timing (before/after/async intent), safe patterns (no current.update() recursion), conditions, reuse via Script Include.
- Database & performance: addEncodedQuery, GlideAggregate for counts, setLimit(1) for existence checks, avoiding heavy queries.
- Readability & structure: small functions, clear names, useful comments, predictable flow.
- Pitfalls & security: no hard-coded sys_id, avoid .sys_id dot-walk on references, safe display/value handling, no eval/dynamic JEXL.
- Logging: appropriate gs.info/warn/debug on server, noise kept behind properties; no gs.print in prod.
Why developers love it
- Instant feedback: catch risky patterns before they hit production.
- Consistent codebase: everyone follows the same standards automatically.
- Faster reviews: reviewers focus on logic instead of linting.
- Great for onboarding: juniors learn good patterns by example.
Privacy & security
- Local-first analysis: your code is analyzed in the popup.
- No code leaves your browser unless you explicitly click Improve with AI.
- Your API key (if used) is stored locally via Chrome storage and never shared elsewhere by the extension.
Compatibility
- Works with ServiceNow Classic UI, Workspace, and Studio.
- Supports instances on service-now.com and servicenowservices.com.
- Bring confidence to your next deploy.
Install SN Code Analyzer and ship clean, fast ServiceNow scripts every time.
