### `awsAmplify`

The options for the AWS Amplify preset. Main fields are `catchAllStaticFallback`, `imageOptimization` (`path`, `cacheControl`), `imageSettings`, and `runtime` (`nodejs20.x` | `nodejs22.x` | `nodejs24.x`, default `nodejs22.x`). See [Preset Docs](/deploy/providers/aws-amplify).

```ts
export default defineConfig({
  awsAmplify: {
    runtime: "nodejs22.x",
    imageOptimization: { path: "/_image", cacheControl: "public, max-age=3600" },
  },
});
```

### `awsLambda`

The options for the AWS Lambda preset. Set `streaming` to `true` to enable response streaming. See [Preset Docs](/deploy/providers/aws).

```ts
export default defineConfig({
  awsLambda: {
    streaming: true,
  },
});
```

### `azure`

The options for the Azure Static Web Apps preset. Use `config` to customize the generated `staticwebapp.config.json` (e.g. `platform.apiRuntime`, `navigationFallback`). See [Preset Docs](/deploy/providers/azure).

```ts
export default defineConfig({
  azure: {
    config: { platform: { apiRuntime: "node:20" } },
  },
});
```

      memoryMiB: 512,
      maxInstances: 10,
    },
  },
});
```

### `iis`

The options for the IIS presets. Use `mergeConfig` to merge the generated `web.config` with an existing one, or `overrideConfig` to replace it entirely. See [Preset Docs](/deploy/providers/iis).

```ts
export default defineConfig({
  iis: {
    mergeConfig: true,

```ts
export default defineConfig({
  netlify: {
    config: {
      redirects: [{ from: "/old", to: "/new", status: 301 }],
    },
  },
});
```
