Custom Audits and Assertions
Develop your own Lighthouse audits to enforce specific performance or best practice rules relevant to your project.
Extend Lighthouse's Power
Welcome to creating custom Lighthouse audits! While Lighthouse offers many built-in checks, sometimes you need to enforce project-specific rules or validate unique performance requirements.
This lesson shows you how to build your own.
Why Create Custom Audits?
Custom audits allow you to tailor Lighthouse to your exact needs. They help you:
- Enforce Standards: Check for specific coding patterns or component usage.
- Validate Unique Metrics: Measure performance aspects not covered by default.
- Ensure Compliance: Verify project-specific accessibility or SEO rules.
- Automate Checks: Integrate tailored performance feedback directly into your development workflow.
