Implement WebFinger with AWS CloudFront and AWS Lambda

 July 24, 2023

This website is hosted on AWS S3 and uses AWS CloudFront as CDN. I use a couple of AWS Lambda@Edge functions to make AWS CloudFront a little brighter. When I decided to self-host a Fediverse instance, it became immediately evident that I would have to set up WebFinger on my domain to be able to use my root domain as the account domain. There is documentation on the web on how to set up WebFinger, but it is aimed at different setups, so I had to configure it myself.

GoLang vanity urls on AWS Lambda

The first thing we will need is to import the github.com/aws/aws-lambda-go package. This package will provide us with the needed functions to easily integrate our Go code with AWS Lambda.
