matthewkeil/convert-lambda-to-express

Production-ready package to run your lambda workloads as an express server. Built with both developers and enterprise in mind.

convert-lambda-to-express provides fully features event and context objects to your handlers and there should be no need to modify your existing code. If you rely on the ENVIRONMENT variables that lambda provides, those are accounted for as well.

Running apiGateway/lambda locally during development can be a challenge (to say the least). The other options out there are either too slow or too complicated. This package aims to solve this problem by providing a simple way to run your api locally. It allows you to wrap your handlers and serve them from an express server.

Makes development of lambda api's a breeze. This package was developed because the other options available for running lambdas, like sam local, serverless-offline or docker-lambda, require docker containers. They are all VERY slow hot-reloading or do not provide that feature at all (how does one dev without hot reload these days?!?!).

Hate your, now baked-in, vendor lock and the non-portable lambda function signature? Have you found that concurrency limits for very choppy traffic and extremely high workloads hard to reserve concurrency for? Just want to use an auto-scaling group or kubernetes cluster now that you've grown? Do you have long running, but very low resource tasks that end up costing an arm and leg on Lambda. Depending on your specifics it can end up being much more effective/cost-efficient to run you system on EC2 or a kubernetes cluster. Rest assured this is a production-ready package that is built for a bulletproof base with express.
