title: workflowPlugin
description: Configure Vite to transform workflow directives in SvelteKit.
type: reference
summary: Add workflowPlugin to your Vite config to enable workflow directive transformation in SvelteKit apps.
prerequisites:
  - /docs/getting-started/sveltekit
---

Returns the Vite plugins that transform workflow code (`"use step"`/`"use workflow"` directives) and build the workflow bundles in a SvelteKit app.

## Usage

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

```typescript title="vite.config.ts" lineNumbers
import { sveltekit } from "@sveltejs/kit/vite";
import { defineConfig } from "vite";
import { workflowPlugin } from "workflow/sveltekit"; // [!code highlight]

export default defineConfig({
  plugins: [sveltekit(), workflowPlugin()], // [!code highlight]
});
```

## API signature

### Parameters

| Parameter | Type | Description |
| --- | --- | --- |
| `options` | `WorkflowPluginOptions` | Optional. Configures the workflow build. |

#### WorkflowPluginOptions

| Option | Type | Default | Description |
| --- | --- | --- | --- |
| `sourcemap` | `boolean \| 'inline' \| 'linked' \| 'external' \| 'both'` | `'inline'` (dev) / `false` (prod) | Controls source maps on generated workflow bundles. Accepts the same values as esbuild's `sourcemap` option. Defaults to `'inline'` in development and `false` in production (smaller function bundles, which helps stay under the Vercel 250 MB function size limit). Set it explicitly, or use the `WORKFLOW_SOURCEMAP` environment variable, to override in either environment. |

### 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.
