Rules & checks
Requires top-level log object with entries array.
Each entry must include a request.url (absolute) and response.status (number).
Counts entries and pages; runs fully client-side.
When to use it
- QA network captures before sharing with engineering/support
- Validate HAR uploads in debugging tools
- Preflight performance traces before analysis
Tips
- Ensure captures include full URLs (not relative) for accurate replay/analysis
- Remove sensitive headers before sharing HARs externally
Examples
Missing URL
- Entry without request.url -> flagged
Relative URL
- request.url = /path -> flagged
FAQs
- Is my HAR uploaded?
- No. Validation is local; refreshing clears it.
- Do you check timing details?
- This focuses on structure. Use perf tools for deep timing analysis.
