Using Node, and no framework currently? Try lambda-local.

Step 2: Push a container from your local machine to ECR. Currently, I use sample python lambda docker from https://github.com/lambci/docker-lambda.git

You can see the following projects for some examples of using this plugin to build a layer. They all leverage Docker and the docker-lambda images to compile for AWS’s Lambda environment on any operating system:

I end up using Lambda a lot so lambci is very useful for local testing: https://github.com/lambci/docker-lambda

There are kind souls in this world who created this: https://github.com/lambci/docker-lambda

If all you need is the ability to run a lambda function's code locally you might interested in docker-lambda[1]. I haven't really used localstack or SAM but a couple of years ago when we needed to run some lambda functions locally for development docker-lambda worked well enough.

Docker Lambda — Docker Lambda is a tool which tries to replicate the AWS Lambda environment as closely as possible, but within a Docker container. Docker Lambda has support for most of the AWS Lambda run times.

Want to emulate AWS environments? Try docker-lambda.
