Dependency Cacher for Dart Frog

An opinionated caching and dependency injection suite for Dart Frog.

This packaged supports:

• Only creating dependencies the first time they are requested.
• Caching dependencies so they are only built once.
• Allows for dependencies to be built asynchronously.
• Allows caching and requesting via a unique key if you need to cache dependencies of the same type.

Providing a dependency

Handler middleware(Handler handler) {
  return handler
      .use(
        futureProvider<MyDependency>(
          (context, {key}) => makeMyDependencyAsync();
        )
      );
}

Using a dependency

Response onRequest(RequestContext context) async {
  final myDependency = await context.readAsync<MyDependency>();
  /// use myDependency...
}
