LambdaSharp.ApiGateway

This package contains interfaces and classes used for building Lambda functions on AWS which integrate with API Gateway and API Gateway V2. This package extends the functionality provided the LambdaSharp package.

ALambdaApiGatewayFunction

The ALambdaApiGatewayFunction base class provides capabilities for mapping REST API and WebSocket endpoints defined in the LambdaSharp module file directly to methods of the class.

public sealed class Function : ALambdaApiGatewayFunction {

    //--- Constructors ---
    public Function() : base(new LambdaSharp.Serialization.LambdaSystemTextJsonSerializer()) { }

    //--- Methods ---
    public override async Task InitializeAsync(LambdaConfig config) {

        // TO-DO: add function initialization and reading configuration settings
    }

    public async Task<AddItemResponse> AddItem(AddItemRequest request) {

        // TO-DO: add business logic for API Gateway resource endpoint
        return new AddItemResponse { };
    }
}

In the corresponding Module.yml file might look something like this:

- Function: MyFunction
  Memory: 128
  Timeout: 30
  Sources:
    - Api: POST:/items
      Invoke: AddItem

ALambdaApiGatewayFunction (Proxy)

The ALambdaApiGatewayFunction base class can also be used to process generic API Gateway invocations.

public sealed class Function : ALambdaApiGatewayFunction {

    //--- Constructors ---
    public Function() : base(new LambdaSharp.Serialization.LambdaSystemTextJsonSerializer()) { }

    //--- Methods ---
    public override async Task InitializeAsync(LambdaConfig config) {

        // TO-DO: add function initialization and reading configuration settings
    }

    public override async Task<APIGatewayProxyResponse> ProcessProxyRequestAsync(APIGatewayProxyRequest request) {

        // TO-DO: add business logic for API Gateway proxy request handling

        return new APIGatewayProxyResponse {
            Body = "Ok",
            Headers = new Dictionary<string, string> {
                ["Content-Type"] = "text/plain"
            },
            StatusCode = 200
        };
    }
}
