cloudfront-emulator

Test your lambda@edge functions locally.

Have you ever found it frustrating to develop lambda@edge functions? Are you tired of editing your code, publishing a new version, updating the Cloudfront distribution, clear the cache, waiting for propagation to finish, and waiting to see your logs in Cloudwatch?

Demo

To demo this, clone the repo down and run

go run ./... example/cookie-redirect
