Local server extremely slow since 0.27

[derkoe]

Describe the bug Since version 0.27 slidev hangs (or is very slow) when running from a project with multiple slides.

To Reproduce Steps to reproduce the behavior:

1. Clone https://github.com/fguisso/talks.git
2. Update the dependency of @slidev/cli to the current version (0.28.5)
3. run npm i
4. run npm run dev -- slides/top-10.md
5. See the process hanging/running at 100% cpu. It will finish after 1-2 minutes building

Desktop (please complete the following information):

• OS: Linux fedora 5.16.8-200.fc35.x86_64
• Browser: any
• Slidev version: 0.28.5

On windows the server will not even start if the markdown files are in a subdirectory with error: [vite] Internal server error: EMFILE: too many open files

Last known working version was 0.27.13. It may be the same error: Does it start normally if you put top-10.md in the project root directory?

Hi,

Same behaviour here, tested with :

• Node 18 LTS and 20
• Slidev v0.40.16 and v0.42.4
• Ubuntu 20.04 WSL2 and Oracle Linux 8.7

Browser : Firefox 113

Could we reopen this issue ? @antfu maybe ?

Thanks !
