serverpod-upgrading

Serverpod minor/patch upgrade

Requirements for this Serverpod version: Dart 3.12.2+, Flutter 3.44.4+. Check the release notes for the version being installed.

Use the same pinned Serverpod version across all packages. Use the CLI to do the upgrade. Ask the user to start the server with serverpod start after the upgrade. NEVER update the CLI tooling, instead STOP and ask the user to do it.

1. Check the latest version of Serverpod: https://pub.dev/packages/serverpod (unless the user has requested a specific version).
2. Run serverpod version to verify that the tooling has the correct version. If not, STOP and ask the user to install the correct version (dart install serverpod_cli for latest or dart install serverpod_cli 3.x.x for specific version).
3. Update all Serverpod packages in all relevant package pubspec.yaml (server, client, flutter, shared).
4. Run dart pub upgrade in all packages.
5. Run serverpod generate.
6. Run serverpod create-migration.
7. Run dart analyze in the root of the project and address any issues.
8. Ensure that the Dockerfile uses at least FROM dart:3.12.2 AS build.
9. Inform the user that the upgrade is complete and they should start the server with serverpod start.

Major upgrade: Serverpod 3.x to 4.0

After following the regular upgrade process, address the following breaking changes.

Streaming: The legacy streaming session and the deprecated streaming APIs are removed. Endpoints must use streaming methods (Stream<T> parameters and return types). See Serverpod Streams.

Future calls: pod.registerFutureCall(...), FutureCall.invoke, pod.futureCallWithDelay(...) and pod.futureCallAtTime(...) are removed. Define methods on the FutureCall class and schedule them through the generated pod.futureCalls API. See Serverpod Scheduling.

Server events: postMessage now defaults to global delivery (falling back to local when Redis is disabled). Pass scope: MessageScope.local where messages must not leave the server instance.

ORM: The deprecated orderDescending parameter is removed. Use orderBy: (t) => t.column.desc() or orderByList.

Endpoints: The ignoreEndpoint annotation is removed. Use @doNotGenerate.

Web server: The deprecated widget classes and legacy static directory classes are removed. Use WebWidget, TemplateWidget, ListWidget, JsonWidget, RedirectWidget and StaticRoute.directory(...). WidgetRoute.build now returns Future<WebWidget?>, where null responds with 404.

Auth: The authenticationKeyManager client parameter is removed; use authSessionManager (Flutter) or authKeyProvider. The native Google Sign-In web implementation is replaced by OAuth2, and dead email exceptions are removed. flutter_secure_storage must be 10.0.0 or newer. On Android, upgrading from 9.x directly to 11.x signs users out; go through 10.x first. 11.x also needs compileSdk 37.

Server: SerializationManagerServer is replaced by DatabaseSerializationManager. Generated projects now import src/generated/serverpod.dart and create the server with Serverpod(args); the Serverpod(args, Protocol(), Endpoints()) form still works, but prefer the new simpler form.

Major upgrade: Serverpod 2.x to 3.0

After following the regular upgrade process, ensure that the following breaking changes are addressed.

Breaking changes

Web server (Relic):

• handleCall: HttpRequest → Request, Future<bool> → FutureOr<Result>, return Response.ok(...) instead of writing to response
• request.remoteIpAddress → request.remoteInfo; request.headers.value('name') → request.headers['name']
• Widget renames: AbstractWidget→WebWidget, Widget→TemplateWidget, WidgetList→ListWidget, WidgetJson→JsonWidget, WidgetRedirect→RedirectWidget
• RouteStaticDirectory(...) → StaticRoute.directory(Directory(...)) with cacheControlFactory

Session.request: Optional request property on Session (null for non-HTTP sessions).

Enum serialization: Default now byName. Add serialized: byIndex in YAML to keep old behavior.

Models: SerializableEntity → SerializableModel. YAML: parent=table → relation(parent=table); database → scope=serverOnly; api → !persist.

Auth: session.authenticated is now synchronous. AuthenticationInfo.authId non-nullable, userIdentifier is String. Client: authenticationKeyManager → authKeyProvider. Custom handlers receive unwrapped Bearer token.

Deprecated: Legacy streaming endpoints; use streaming methods.
