Tip

This page is best viewed through the site search or through the AI.

Uses aws-lambda-go-api-proxy to allow you to run a Go API with API Gateway V2.

Tip

We use the aws-lambda-go-api-proxy package to handle the API Gateway V2 event.

So you write your Go function as you normally would and then use the package to handle the API Gateway V2 event.

main.go

import (
 "github.com/aws/aws-lambda-go/lambda"
 "github.com/awslabs/aws-lambda-go-api-proxy/httpadapter"
)

func router() *http.ServeMux {
  mux := http.NewServeMux()

  mux.HandleFunc("/", func(w http.ResponseWriter, r *http.Request) {
    w.Header().Set("Content-Type", "application/json")
    w.WriteHeader(http.StatusOK)
    w.Write([]byte(`{"message": "hello world"}`))
  })

  return mux
}

func main() {
  lambda.Start(httpadapter.NewV2(router()).ProxyWithContext)
}

sst.config.ts

const api = new sst.aws.ApiGatewayV2("GoApi");

api.route("$default", {
  handler: "src/",
  runtime: "go",
});
