aws-lambda-power-tuning
AWS Lambda Power Tuning is an open-source tool that can help you visualize and fine-tune the memory/power configuration of Lambda functions. It runs in your own AWS account - powered by AWS Step Functions - and it supports three optimization strategies: cost, speed, and balanced.

Since I was already using middy in the project, I discovered their http-router: a simple utility that forwards events to handlers based on method and path. It also handles extracting path parameters if you're using a /{proxy+} route in your API Gateway.

And then I looked at how many Node.js projects still depend on dynalite for local DynamoDB. I owe a lot to dynalite. Using it through arc.codes and Architect is what turned DynamoDB from a database I'd reach for occasionally into the one I'd reach for first. Having a fast local emulator that just worked changed how I thought about building with DynamoDB. It made the feedback loop tight enough that I actually wanted to experiment. But dynalite hasn't seen updates in a while and newer DynamoDB features like transactions and streams aren't covered. Dynoxide supports both, along with the rest of the API surface. With an npm package shipping platform-specific binaries (the same approach esbuild and Biome use), it works as a drop-in replacement. Same workflow, one line change in your package.json.
