title: workflow
description: Configure Vite and Nitro to transform workflow directives.
type: reference
summary: Add the workflow plugin to your Vite config to enable workflow directive transformation in Vite + Nitro apps.
prerequisites:
  - /docs/getting-started/vite
---

Returns the Vite plugins that transform workflow code (`"use step"`/`"use workflow"` directives) and configure the [`workflow/nitro`](/docs/api-reference/workflow-nitro) module on the Nitro server. It is designed to be used alongside `nitro()` from `nitro/vite`, which provides the server framework for API routes and deployment.

## Usage

To enable `"use step"` and `"use workflow"` directives while developing locally or deploying to production, add `workflow()` to the `plugins` array of your Vite config, together with `nitro()`.

```typescript title="vite.config.ts" lineNumbers
import { nitro } from "nitro/vite";
import { defineConfig } from "vite";
import { workflow } from "workflow/vite"; // [!code highlight]

export default defineConfig({
  plugins: [nitro(), workflow()], // [!code highlight]
  nitro: {
    serverDir: "./",
  },
});
```

## API Signature

### Parameters

| Parameter | Type | Description |
| --- | --- | --- |
| `options` | `ModuleOptions` | Optional. Forwarded to the `workflow/nitro` module as its module options. |

#### ModuleOptions

| Option | Type | Default | Description |
| --- | --- | --- | --- |
| `dirs` | `string[]` | — | Directories to scan for workflows and steps. By default, the `workflows/` directory is scanned from the project root and all layer source directories. |
| `typescriptPlugin` | `boolean` | `false` | Adds the `workflow` TypeScript plugin to the generated `tsconfig.json` for IDE IntelliSense. |
| `runtime` | `string` | — | Node.js runtime version for Vercel Functions (e.g. `'nodejs22.x'`, `'nodejs24.x'`). Only applies when deploying to Vercel. |
| `sourcemap` | `boolean \| 'inline' \| 'linked' \| 'external' \| 'both'` | `'inline'` | Controls source maps on generated workflow bundles. Accepts the same values as esbuild's `sourcemap` option. Set to `false` for smaller function bundles (useful for staying under the Vercel 250MB function size limit) at the cost of stack traces pointing at generated code. Can also be set via the `WORKFLOW_SOURCEMAP` environment variable. |

### Returns

Returns an array of Vite `Plugin` objects. Spread or pass the array directly to the `plugins` option of your Vite config — Vite flattens nested plugin arrays automatically.
