Rust/WASM on AWS Lambda@Edge (CloudFront)

Rust/Wasm on AWS Lambda@Edge (CloudFront)

Read the accompanying blog post to this project.

Since we still cannot have native Rust (or WebAssembly for that matter) on AWS Lambda@Edge, we have to come up with our own solution. Here I present mine: using the AWS Lambda Node.js enviroment to execute our Wasm blob generated from Rust code.

tl;dr

make build
make call
make zip
# upload to your AWS Lambda and attach it to a CloudFront distribution (as viewer request trigger)
# check the Cloudwatch logs in the regions you made requests
# be happy - Have a nice day!

This demo doesn't do anything fancy. In fact, it does not alter the request at all and only passes it through as-is.

The function will make a few log statements, check the Cloudwatch logs in the regions you received requests for your CloudFront distribution.

This setup is good to test for the baseline performance.

After the cold-start some requests later the function duration should be around 1 to 2 ms.

Depending on the region and where you are, this translates to 40 to 50 ms in request latency for a small static asset, while without any trigger attached the same request would take around 25 ms.

Bug Report

I mostly worked on Rust and recently need to deploy some of our services written in Rust to AWS Lambda@Edge and this is a great example to start with, thanks

the test code running well both in local and AWS cloudfront. I use this as the framework and link our code as crates, and then I have the following error when run "make call" I don't really known how to solve it (I've searched the rollup document but still don't get how to solve this, since I don't use rollup before).

do you know what it might issue with this, thanks a lot!

Error: Could not dynamically require "./snippets/app_edge-d7b4f29aba445e31/inline0.js". Please configure the dynamicRequireTargets or/and ignoreDynamicRequires option of @rollup/plugin-commonjs appropriately for this require call to work.
