# Genkit Shelf Plugin (`genkit_shelf`)
|
|
|
|
Shelf integration for Genkit Dart, used to serve Genkit Flows.
|
|
|
|
## Standalone Server
|
|
Serve Genkit Flows easily on an isolated HTTP server using `startFlowServer`.
|
|
|
|
```dart
|
|
import 'package:genkit/genkit.dart';
|
|
import 'package:genkit_shelf/genkit_shelf.dart';
|
|
|
|
void main() async {
|
|
final ai = Genkit();
|
|
|
|
final flow = ai.defineFlow(
|
|
name: 'myFlow',
|
|
inputSchema: .string(),
|
|
outputSchema: .string(),
|
|
fn: (String input, _) async => 'Hello $input',
|
|
);
|
|
|
|
await startFlowServer(
|
|
flows: [flow],
|
|
port: 8080,
|
|
);
|
|
}
|
|
```
|
|
|
|
## Existing Shelf Application
|
|
Mount Genkit Flow endpoints directly to an existing Shelf `Router` using `shelfHandler`.
|
|
|
|
```dart
|
|
import 'package:genkit/genkit.dart';
|
|
import 'package:genkit_shelf/genkit_shelf.dart';
|
|
import 'package:shelf/shelf.dart';
|
|
import 'package:shelf/shelf_io.dart' as io;
|
|
import 'package:shelf_router/shelf_router.dart';
|
|
|
|
void main() async {
|
|
final ai = Genkit();
|
|
|
|
final flow = ai.defineFlow(
|
|
name: 'myFlow',
|
|
inputSchema: .string(),
|
|
outputSchema: .string(),
|
|
fn: (String input, _) async => 'Hello $input',
|
|
);
|
|
|
|
final router = Router();
|
|
|
|
// Mount the flow handler at a specific path
|
|
router.post('/myFlow', shelfHandler(flow));
|
|
|
|
// Start the server
|
|
await io.serve(router.call, 'localhost', 8080);
|
|
}
|
|
```
|
|
|
|
Access deployed flows using genkit client libraries (from Dart or JS).
