+# Workflows with ElysiaJS Node (Nitro v3)
+
+- Learn more about ElysiaJS: https://elysiajs.com/
+- Learn more about Nitro: https://v3.nitro.build/
+
+## Commands
+
+**Local development:**
+
+```sh
+npm run dev
+```
+
+**Production build (Vercel):**
+
+```sh
+NITRO_PRESET=vercel npm run build
+npx vercel --prebuilt
+```
+
+**Production build (Bun):**
+
+```sh
+npm run build
+bun run .output/server/index.mjs
+```
+
+## Limitations
+
+Currently, Nitro does not support passing `idleTimeout` to the underlying Bun server that ElysiaJS uses. By default, Bun sets `idleTimeout = 10` seconds, which means workflow suspensions over 10 seconds will fail.
