gateway VS aws-lambda-go-api-proxy

We had great success with https://github.com/apex/gateway

I write Lambda functions in golang. In dev I run the function as local http server. In prod I map a custom domain to the lambda, routing is done internally to the function. API Gateway is only used for the top level route. This workflow is enabled by https://github.com/apex/gateway

In principle I try to avoid Amazon Web Services that lock me into the platform. So, for my dev stack I run a few other containers to give me the equivalent of the prod environment, RDS (MySQL or PostgreSQL), ES (OpenDistro), S3 (Minio), and SES

I really like the extensibility of LangChain. While I understand that langchaingo may not be as popular as the original python version (I hope it will reach there in due time 🤞), but it's nice to be able to use it as a foundation and build extensions as required. Previously, I had written about how to use the AWS Lambda Go Proxy API to run existing Go applications on AWS Lambda. The AWS Lambda Web Adapter offers similar functionality but it has lots of other benefits, including response streaming and the fact that it is language agnostic.

A frustration shoutout to the aws maintainers that are ignoring PRs that enhance the usability of their services... even for over a year. https://github.com/awslabs/aws-lambda-go-api-proxy/pull/136

Check out https://github.com/awslabs/aws-lambda-go-api-proxy. It will allow you to run gin (or other http servers) in lambda.

For REST APIs, I create standard Go HTTP handlers, and use a library like https://github.com/a-h/awsapigatewayv2handler (mine, for API Gateway V2 only), or AWS's https://github.com/awslabs/aws-lambda-go-api-proxy or github.com/akrylysov/algnhsa to convert from Lambda handlers to standard Go HTTP handlers.

Hey I liked this post, seems really nice. I used Golang for an API in my current work, I used the gorillamux with this library https://github.com/awslabs/aws-lambda-go-api-proxy. It wraps the API into the APIGateway Proxy. You can use it too if you want to create a small API, there are examples with cloudformation there.

using {proxy+} on api gateway, route handler needs to be included. People should consider using github.com/awslabs/aws-lambda-go-api-proxy (with gin or mux)

This does something similar: https://github.com/awslabs/aws-lambda-go-api-proxy

As you can see, we defined that any path and method can trigger our lambda over API Gateway that we had previously created. With this approach and with using this solution with the Go Echo framework, we reduced the number of lambdas (also with this approach we solved the problem with a hard limit of total size that all lambdas can have). Using the aws-lambda-go-api-proxy with echo framework we defined a REST controller that is managing real paths and methods that our lambda consumes.

For our example which use the Go Gin framework, to minimize the changes we could also use the great AWS Lambda Go API Proxy. You can find an example of lambda function in the article repository

AWS actually provides wrappers for most HTTP handler functions in their adapter package: https://github.com/awslabs/aws-lambda-go-api-proxy
