@Relative_CI has made us substantially more conscious on bundle size monitoring/analysis every day we love their service!✨

@Relative_CI is pretty cool. It just helped me discover and fix duplicate packages on my site.

It was caused by differently resolved transitive dependencies by radix-ui/* packages

@Relative_CI and @rspack_dev is really a great combo, Fast bundle analysis and monitoring in CI is a must need for long-term projects.

A tool that I really like is @Relative_CI, already in 3 codebases here and it helps a lot analyzing the impact of a dependency in your bundle size

In this screenshot (educational PR), adding moment().format() increases the bundle size in 7%. Good for code review suggestions
