Integrating Lighthouse into CI/CD

Automate Lighthouse checks within your continuous integration and deployment pipelines to catch performance regressions early.

What is CI/CD?

CI/CD stands for Continuous Integration and Continuous Delivery/Deployment. It's a modern approach to software development that focuses on automating various stages of the software lifecycle.

  • Continuous Integration (CI): Developers frequently merge code into a central repository. Automated builds and tests run to detect issues early.
  • Continuous Delivery (CD): After CI, code is automatically prepared for release, ensuring it's always in a deployable state.
  • Continuous Deployment (CD): Takes CD a step further by automatically deploying every change to production, provided all tests pass.

CI/CD helps teams deliver updates faster and more reliably.

Why CI/CD for Performance?

Integrating performance checks into your CI/CD pipeline is crucial for maintaining a fast website. Here's why:

  • Catch Regressions Early: Automatically detect performance drops with every code change, before they reach users.
  • Consistent Feedback: Get objective performance scores on every build, ensuring teams stay aware of their impact.
  • Enforce Standards: Use performance budgets to fail builds if metrics fall below acceptable thresholds.
  • Save Time: Automate manual auditing, freeing up developer time.
