Workflow SDK now runs natively in Nitro v3
By Steven Van ·
Workflow SDK's beta Nitro v3 integration shares one bundled runtime, adds a /_workflow debug UI, and tree-shakes unused code from builds.
Workflow SDK's native integration with Nitro v3 is now in beta, letting workflow steps run inside the same bundled runtime as the rest of a Vercel app instead of a separate bundle. Nitro's useStorage() and other server-side APIs now work directly inside "use step" functions.
- The Nitro dev server serves the workflow web UI at /_workflow, so runs can be inspected, monitored, and debugged in the browser.
- Workflow routes are bundled by Nitro as part of the app build, with dependency tracing and tree-shaking of unused code, resulting in faster builds and smaller bundles.
Details on setting it up are in the Nitro integration guide.
