Add vp dev support for SoldStart/Vinxi server

[gihrig]

Description

vp v0.1.15 vp dev executes the vite dev server (as expected)

SoldStart projects rely on the Vinxi dev server.

The vite dev server does not serve the SolidStart app, only an empty page with a 404 is returned.

Suggested solution

Detect the Vinxi dev server and start that when running vp dev.

Alternative

Support a config property in vite-config.ts. Perhaps adding to the existing server: property.

Additional context

I know I can just run vp run dev or vpr dev but I'm lazy and OCD. 😜

Similar considerations apply to vp build and vp preview.

Validations

Thanks for the report.

You're right that this issue occurs with SolidStart v1. Since those projects rely on Vinxi and your setup starts the Vite dev server directly, it makes sense why it's behaving this way.

However, it looks like SolidStart v2 has moved away from Vinxi and now recommends using native Vite commands for dev, build, and preview, as shown here:

https://docs.solidjs.com/solid-start/migrating-from-v1

Because of that, I'm not sure if adding Vinxi-specific detection is the right move if it only benefits v1 users. For existing v1 projects, the best approach is to continue using vp run dev or vpr dev, as those commands will run the specific scripts defined in your project.

@naokihaba Thank you for the update on v2. I agree completely.
It's not a big issue for v1 users and now it's documented here for anyone who searches.
