This is needed to host OpenCode app under under some URL prefix. This minimal change makes it possible to build OpenCode Web App with VITE_BASE_URL="/subdir/" and have it run under `http://<host>:<port>/subdir/` instead of root (`http://<host>:<port>/`). Set `VITE_BASE_URL` env var during build. This automatically sets the `base` in Vite config. Vite generates correct URLs in `index.html`. `import.meta.env.BASE_URL` is also used in routers. See https://vite.dev/config/shared-options#base You can also set `VITE_OPENCODE_SERVER_BASE_URL` to specify the base URL prefix for the server. Usage: ``` % VITE_BASE_URL="/XXX" VITE_OPENCODE_SERVER_BASE_URL="/" bun dev $ vite (!) "base" option should start with a slash. VITE v7.1.4 ready in 320 ms ➜ Local: http://localhost:3000/XXX ```
