functions_framework 0.4.3+1

FaaS (Function as a service) framework for writing portable Dart functions

0.4.3+1

• Migrate from package:gcp to package:google_cloud.

0.4.3

• Support application/protobuf event encoding.

0.4.2

• Requires Dart 3.0.0.
• Support package:http v1

0.4.1

• Improve package documentation.

0.4.0

• Now null-safe.

• Requires Dart 2.12.0.

• BREAKING RequestContext: removed deprecated headers and headersAll properties.

• BREAKING serve.dart:

  • Changed the signature for serve function accept FunctionTarget Function(String) nameToFunctionTarget instead of Set<FunctionTarget> targets. This will allow more flexibility in future FunctionTarget implementations.
  • FunctionTarget no longer has a const constructor. The name parameter has also been removed.

• Allow the latest versions of args, http, http_parser, and shelf packages.

0.3.1

• functions_framework.dart

  • RequestContext
    • Added request property to access original request.
    • Deprecated headers and headersAll - use request instead.
  • Fix exception on Windows due to SIGTERM handler (PR #153).

0.3.0

• Added support for functions that handle and return JSON data.

• Added support for defining and hosting Cloud Events.

• functions_framework.dart

  • Added CloudEventHandler, CloudEventWithContextHandler, and CloudEvent class to support Cloud Events.
  • Added JsonHandler and JsonWithContextHandler to support functions that handle and return JSON data.
  • Added RequestLogger, LogSeverity, and HandlerWithLogger to support logging from handlers.
  • RequestContext to get access to request headers, logging, and ability to set response headers for CloudEvent and custom handlers.
  • Added BadRequestException class. Functions can throw this exception to cause a 4xx status code to be returned to a request source.

• serve.dart

  • Added JsonFunctionTarget, JsonWithContextFunctionTarget, and BadRequestException classes to support generated code for functions that handle and return JSON data.
  • Added FunctionTarget class. This is the abstract base class that wraps user written functions and links them to a name.
  • BREAKING The signature for serve is now:
Future<void> serve(List<String> args, Set<FunctionTarget> targets)

0.2.0

• BREAKING CloudFunction constructor parameters target is now named and optional. If not specified, it defaults to the name of the annotated function. (Previously, it defaulted to the string 'function'.)
• Detect if running on Google Cloud and generate logs appropriately.
• Improved the error messages and exit codes for failures.
• Correctly respond with 404 with requests for robots.txt and favicon.ico.

0.1.0

This is a preview release of the Functions Framework for Dart to demonstrate http functions support only (cloudevent support is not yet implemented). This is a work in progress and currently does not pass conformance testing.
