API Gateway HTTP Integration

Modules around API Gateway have fallen behind in terms of bug fixes and new features in comparison to Lambda Function URL since I've mostly migrated completely away from API Gateway.

The only redeeming feature of API Gateway at the moment is the authorisers and their ability to cache based on a header or query parameter identity source. Since I've moved to cookie-based authenication and authorisation, however, the point is moot.

package main

import (
	"context"

	"github.com/aws/aws-lambda-go/events"
	"github.com/nguyengg/golambda"
	"github.com/nguyengg/golambda/apigatewayhttpapi"
	"github.com/nguyengg/golambda/apigatewayhttpapi/auth"
	"github.com/nguyengg/golambda/apigatewayhttpapi/framework"
)

func main() {
	// without a context wrapper.
	apigatewayhttpapi.Start(func(ctx context.Context, request events.APIGatewayV2HTTPRequest) (events.APIGatewayV2HTTPResponse, error) {
		// will set LambdaContext.AwsRequestID to log prefix and reset upon completion.
		defer logsupport.SetUpGlobalLogger(ctx)()

		return events.APIGatewayV2HTTPResponse{
			StatusCode: 200,
			Body:       "hello, world!",
		}, nil
	})

	// with a context wrapper.
	framework.Start(func(c *framework.Context) error {
		return c.RespondOKWithText("hello, world!")
	})

	// authorizer example.
	auth.StartV2(func(ctx context.Context, request events.APIGatewayV2CustomAuthorizerV2Request) (events.APIGatewayV2CustomAuthorizerSimpleResponse, error) {
		return events.APIGatewayV2CustomAuthorizerSimpleResponse{
			IsAuthorized: true,
		}, nil
	})
}
