This PR adds an integration test with Vue where we use a 1000 components and where each component references a CSS file via `@reference`. Each component has a unique class that uses `@apply`. There are some discussions in https://github.com/tailwindlabs/tailwindcss/discussions/16429 that mention that this causes OOM issues. Right now I can't reproduce that, and even with a 1000 components, it produces CSS in a reasonable time: ``` vite v7.3.3 building client environment for production... ✓ 2011 modules transformed. dist/index.html 0.23 kB │ gzip: 0.18 kB dist/assets/index-DNVNFkYQ.css 106.65 kB │ gzip: 10.79 kB dist/assets/index-B8v7EbAN.js 223.84 kB │ gzip: 49.81 kB ✓ built in 3.17s ``` I also started a Vite server and triggered file changes to see if the memory would grow forever, which it didn't. After a 1000 changes, everything still behaves smoothly: <img width="1694" height="1856" alt="image" src="https://github.com/user-attachments/assets/b16800ae-4dce-4f0d-9d97-25f4cab21c1c" /> Making changes manually to a single component, result in proper HMR request that update the browser: https://github.com/user-attachments/assets/5c79ffc6-2329-4341-9d25-82b000093e31 This test is here to make sure that it keeps working in the future. --- If I remove all `@reference` references, and usages of `@apply`, then the build time is indeed faster: ``` vite v7.3.3 building client environment for production... ✓ 2011 modules transformed. dist/index.html 0.23 kB │ gzip: 0.18 kB dist/assets/index-CcxXccJ1.css 106.61 kB │ gzip: 10.76 kB dist/assets/index-M92YFF0G.js 223.84 kB │ gzip: 49.81 kB ✓ built in 1.97s ``` So we go from `1.97s` → `3.17s`, which is a `1.2s` increase when you use `@reference` with `@apply` in 1000 files for a fresh build. I also saw some comments about the CSS growing whenever `@reference` was used, but as you can see in the snippets above they are at a stable size. ## Test plan 1. All tests still pass [ci-all] For testing on Windows / macOS --------- Co-authored-by: greptile-apps[bot] <165735046+greptile-apps[bot]@users.noreply.github.com> |
