Hello everyone,

_this is my first project with Node-RED - so please be patience with me_ 🙂

My goal is to provide a very small runtime which reduces cold start times and allows to use flows to build AWS Lambda functions without editor support.

**Current Results:**

- Package-Size for simple Event IN-\>OUT flow: 1.5MB
- Lambda Coldstart Duration: 50ms / Init Duration: 350.54 ms
- Lambda recurrent calls Duration: 1.8-2.0ms (Memory Size: 1024 MB Max Memory Used: 89 MB)

The created single Javascript file can be executed in any Node \>=14 environment. All needed Node-RED modules and Nodes (needed by the flow) are included.

I am happy to hear your Feedback and yes, the cold start times need some more work.

> Bundle Node-RED and all required node into one minified javascript file for AWS Lambda and command line apps.

Thanks to everyone for the existing software I was able to built on.
