Jakar.Json.AwsLambda

An AWS Lambda serializer on Jakar.Json.

  • Requests and responses of [JsonModel] types, and of arrays, lists and collection interfaces of them, are read and written without reflection.
  • Every other type goes to a fallback serializer. That covers the AWS event types (API Gateway, SQS, ...).
// Native AOT friendly: the fallback is System.Text.Json's source-generated Lambda serializer.
[assembly: LambdaSerializer(typeof(JakarJsonLambdaSerializer<SourceGeneratorLambdaJsonSerializer<MyJsonContext>>))]

// Or, with reflection-based System.Text.Json for other types:
[assembly: LambdaSerializer(typeof(JakarJsonLambdaSerializer))]

You can also pass it to the runtime client: LambdaBootstrapBuilder.Create(handler, new JakarJsonLambdaSerializer<...>()).

  • Native AOT: Lambda's fast cold starts are a natural fit for a reflection-free serializer. With a source-generated fallback, the whole function stays AOT and trimming compatible. The parameterless JakarJsonLambdaSerializer uses DefaultLambdaJsonSerializer (reflection) for other types, and is annotated as such.
  • Requests are read into a pooled buffer and parsed in one pass. Responses are written from a pooled buffer.
  • Errors: malformed requests throw JsonReadException.
