AppServer.vite runs npm run dev with --host 127.0.0.1, a fixed port, --strictPort, and --open=false, waits until the ready URL responds, then kills the process on Scope exit. Customize with ServeConfig / AppServer.serve when the recipe differs.

#Static files

For a directory of HTML/JS without a bundler:

StaticFileServer.layer(Path.of("path/to/static"))

Same readiness + Scope story; pick the helper that matches the fixture.

#Ascent / Scala.js link output

When Vite must see linked Scala.js output, point the fixture at the sbt link directory (this repo’s ascent example uses SCALAJS_OUT_DIR so Vite and fastLinkJS do not deadlock). That wiring lives in the consuming build, not inside Chekhov core. Chekhov only starts the server and drives the browser once baseUrl is up.

ServeConfig(
          command = List("npm", "run", "dev"),
          cwd = Path.of("examples/vite-fixture"),
          readyUrl = "http://127.0.0.1:5173"
