Migration guide

Spry includes some behavior and API changes that you need to consider applying when migrating.

Spry 5 to Spry 6

App instance

• app.stack -> app.middleware
• app.group/app.grouped -> Removed it, Use the app.use replace.

Request

• useRequest() -> event.request
• useHeaders() -> event.headers/event.request.headers
• getClientAddress() -> event.address
• useRequestURI() -> event.url
• useParams() -> event.params

Adapters

Please remove your adapter code, including to{Platform}Handler, and use app.serve instead:

Before:

dart:io

final handler = toIOHandler(app);
final server = await HttpServer.bind('127.0.0.1', 3000);

server.listen(handler);

Other e.g Bun

final serve = toBunServe(app)
  ..port = 3000;

Bun.serve(serve);

Now:

final server = app.serve(port: 3000);
await server.ready();
