pkg/dwds/CHANGELOG.md

## 27.1.1-wip

- Replace raw map for client ping checks with a proper `PingRequest` class and update client deserialization handling.

## 27.1.0

- Add `appName` to `DartDevelopmentServiceConfiguration`.

## 27.0.3

- Fix `dartExecutable` not being correctly passed to the DebugService.

  - Update dwds to support ignoring disconnects for the SseHandler. This is
    useful to prevent incorrect behavior when a disconnect event arrives after
    a new connection request.

- Fix `FormatException` in `ExtensionDebugger` by making `ExtensionEvent.fromJson` robust to missing headers and Map-typed params.
- Fix `StateError` in `DwdsInjector` during AOT execution by bundling `client.js` as a statically compiled asset.

## 27.0.0

- Remove `package:built_value`, `package:built_value_generator`, and `package:built_collection` dependencies.
- Remove `serializers.dart` and `data_serializers.dart`.
- Remove `package:built_value` dependency from `ConnectFailure`, `DebugStateChange`, `DevToolsOpener`, `DevToolsUrl`, `IsolateStart`, `IsolateExit`, `DevToolsRequest`, `DevToolsResponse`, `ExtensionRequest`, `ExtensionResponse`, `ExtensionEvent`, and `BatchedEvents`; switch to standard Dart JSON serialization.
- Update `ConnectFailure`, `DebugStateChange`, `DevToolsOpener`, `DevToolsUrl`, `DevToolsRequest`, `DevToolsResponse`, `ExtensionRequest`, `ExtensionResponse`, `ExtensionEvent`, `BatchedEvents` and `DebugInfo` serialization to mimic `built_value`'s list-based format to resolve compatibility issues with the debug extension.
- Remove `build`, `build_daemon`, `build_runner`, `build_version`, `build_web_compilers`, and `pubspec_parse` dependencies, along with `build.yaml` which originally generated `client.js` using `build_runner`. `client.js` is now compiled via `dart compile js` in a new `tool/build.dart` script.
- Throw `RPCError` when providing invalid `pause_isolates_on_start` values to the Chrome Proxy Service.
- Fix deserialization of `HotRestartRequest`, `HotReloadResponse`, `HotRestartResponse`, and `ServiceExtensionResponse` in the `DevHandler`.

## 26.2.0

  `WebSocketProxyService` as we didn't actually pause.

## 26.0.0

## 25.0.4

  would be spammed on the console.

## 25.0.3

### Bug Fixes:

  sources path, resulting in a null assertion.

## 25.0.2

### Bug Fixes:

- Fix issue where DDS would fail to initialize if DWDS already had existing
  clients.

## 25.0.1

### Bug Fixes:

- Fix issue in hot restart where a hot restart with no changes followed by one
  with changes, a `Future` was completed again, resulting in a crash.

## 25.0.0

- Implemented hot restart over websockets with multi window support.
- Fix refresh race condition bug by adding an isolate destruction grace period.
- Update a call to the `package:shelf_web_socket` `webSocketHandler()` function.

**Breaking changes**

- Remove deprecated parameter `injectDebuggingSupportCode` from `Dwds.start()`.
- Remove all deprecated fields, getters, and parameters
  related to the null safety compilation mode. Dart 3 only
  supports [sound null safety](https://dart.dev/null-safety).
- Rename `FrontendServerDdcLibraryBundleStrategy.hotReloadSourcesUri` to
  `reloadedSourcesUri`. The file that the `Uri` points to should now be updated
  for both a hot restart and a hot reload.

## 24.4.1

- Implemented a WebSocket-based communication protocol that provides essential developer tooling (hot reload, service extensions) when Chrome debugger access is unavailable. - [#2605](https://github.com/dart-lang/webdev/issues/2605)
- Added WebSocket-based hot reload and service extension support via new `WebSocketProxyService` class that implements VM service protocol over WebSockets.
- Enhanced `DevHandler` with `useWebSocketConnection` flag to toggle between Chrome-based and WebSocket-based communication protocols.
- Fixed an issue where we didn't wait until all scripts were parsed before
  recomputing metadata on a hot reload.

## 24.4.0

- Added support for breakpoint registering on a hot reload with the DDC library bundle format using PausePostRequests.
- `FrontendServerDdcLibraryBundleStrategy.hotReloadSourceUri` is now expected to also provide the reloaded modules.

## 24.3.11

- Changed DWDS to always inject the client and added `useDwdsWebSocketConnection` flag to control communication protocol: when true uses socket-based implementation, when false uses Chrome-based communication protocol.
- Added WebSocket-based hot reload support: `reloadSources` in `ChromeProxyService` and `DevHandler` now handle hot reload requests and responses over WebSockets.
- Refactored the injected client to use a reusable function for handling hot reload requests and responses over WebSockets.
- Added support for breakpoint registering on a hot restart with the DDC library bundle format using PausePostRequests.

## 24.3.10

- Disabled breakpoints on changed files in a hot reload. They currently do not
  map to the correct locations or are broken, so disable them for now. - [#60186](https://github.com/dart-lang/sdk/issues/60186)

## 24.3.9

- Renamed DWDS Injector parameter `enableDebuggingSupport` to `injectDebuggingSupportCode` for clearer intent.

- Updated DWDS to include a boolean flag that enables debugging support only when set to true. [#60289](https://github.com/dart-lang/sdk/issues/60289)

## 24.3.7

- The registered extension `reassemble` is now no longer called when calling
  `reloadSources`. Users should call `reassemble` using `callServiceExtension`.

- `callServiceExtension` now checks the runtime for the list of registered
  service extensions. It also now throws a `RPCError` with
  `RPCErrorKind.kMethodNotFound` when a service extension is not found instead
  of throwing a JS evaluation error.

## 24.3.6

- Bump minimum sdk version to 3.7.0
- use 'compile js-dev' instead of directly invoking the ddc snapshot.
- `FrontendServerDdcLibraryBundleStrategy` now takes a `hotReloadSourcesUri`
  parameter in order to fetch the file that contains the changed sources and
  libraries instead of assuming it exists in the global `window`.

## 24.3.5

- Allow clients to specify the `packageConfigPath` in `LoadStrategy` class and associated providers.

## 24.3.4

- Added support for some debugging APIs with the DDC library bundle format. - [#2566](https://github.com/dart-lang/webdev/issues/2566), [#2573](https://github.com/dart-lang/webdev/issues/2573)

- Add load strategy and an unimplemented hot restart strategy for DDC library
  bundle format.
- Added `useModuleName` option to `MetadataProvider` to determine whether or not
  to use the provided `name` in a `ModuleMetadata`. Metadata provided by DDC

  generic resource handler. Specific methods for the required resources are now
  clearly defined. The new abstraction is now consumed through `dwds.dart`.

  now consumed through `dwds.dart`.

## 0.9.0
