Description

We need an automated way to monitor the initial bundle size of a page, rather than manually checking it through the build process or PageSpeed Insights. This will help prevent accidental increases in bundle size from being pushed to production. Implementing this as part of our PR checks would ensure better control over page performance.

Tasks

• Measure bundle size on PR
• Create a rule about it

Acceptance Criteria

1. PR check that measure bundle size so it can avoid PRs with increased bundle size to pushed to production
2. New rule is created

PR - #3678

I changed docker build to use @next/bundle-analyzer to generate bundle report files. And from actions there is script that calculates size and adds comment to PR.

Figure: Bundle size comment is added to PR after build
