Logs

Start with the vite.config.ts reproduction and run bun --bun vite dev using the Bun preset and websocket feature. Trace why the dev server selects the crossws Node.js adapter in this environment. Done means websocket support works in Vite dev mode under Bun without the incompatible-environment error.
