MerLoc is a live AWS Lambda function development and debugging tool. MerLoc allows you to run AWS Lambda functions on your local while they are still part of a flow in the AWS cloud remote.
MerLoc makes it possible to - test your function locally without deploy to the AWS Lambda environment (so no wait for build, package and deploy) - debug your function by putting breakpoints from your IDE - hot-reload updated function on your local automatically to apply changes automatically (so again no wait for build, package and deploy) - run the individual function locally while it is still part of flow shown above and use real requests from the AWS Lambda environment
