Seamlessly use Axum on AWS Lambda

axum-aws-lambda

This crate provides a tower::Layer that translates hyper/axum requests to the format used by the aws-lambda-rust-runtime crate. This allows users to switch between just running a Hyper server, and running under the Lambda runtime - this dramatically speeds up development! It also means that you can use off-the-shelf components from the Tower ecosystem!

Check out examples/main.rs: running in debug mode runs a hyper server, and building for release mode compiles using the Lambda runtime.

Testing out the Lambda runtime locally

There is an example Dockerfile for locally spinning up a lambda runtime:

cargo build --release --example main
docker build . -t lambda-test
docker run -p 9000:8080 lambda-test

In test-lambda-runtime/ there is a python script for testing and a Dockerfile for running it.

In another shell, from the root of this repository:

cd test-lambda-runtime
docker build . -t test_lambda_runtime
docker run --network="host" test_lambda_runtime

axum-aws-lambda's Issues

Lambda Context?

What do you think about carrying the lambda_http::Context forward into the request? That data is necessary for auth claims when using Cognito, among other things.

I imagine we'd use Extensions for that; I can take a shot at it if you're interested.

Routing?

I have an axum app with multiple routes. Is there a way to access these routes via the generated lambda function?
