📝 Walkthrough

Summary by CodeRabbit

• Bug Fixes
  • Updated SolidStart project detection to support both v1 and v2 configurations.
  • Correctly identifies Vite-based SolidStart v2 projects, including Netlify’s Vite plugin.
  • Applies the appropriate development port, build commands, and output directory for each SolidStart version.

Walkthrough

SolidStart defaults now use Vite development on port 5173 and build output in dist/client. Detected SolidStart versions before v2 retain Vinxi commands, port 3000, and the dist directory. Tests identify the v1 fixture explicitly and add coverage for SolidStart v2 projects using @solidjs/start 2.x, Vite configuration, and Netlify’s Vite plugin.
