# Best practices
Modern web development standards based on Lighthouse best practices audits. Covers security, browser compatibility, and code quality patterns.
## Evidence-led audit workflow
When a rendered page is available:
1. Run a live Lighthouse Best Practices audit when that capability is available; with Chrome DevTools MCP, use `lighthouse_audit`. Use navigation mode for a normal page load or snapshot mode when the current state must be preserved.
2. Inspect the listed console and network failures and fetch individual details only when they support a finding.
3. Supplement runtime evidence with dependency, header, configuration, and source inspection; Lighthouse is not a complete security assessment.
4. Fix the implicated code, re-run the same audit, and keep security findings separate from style preferences.
If live tools are unavailable, use the Lighthouse CLI plus focused dependency and header checks. Never report a high Lighthouse score as proof that the application is secure.
