For a while, I struggled when it came to making layers for my functions. I used to download them locally, zip them, upload them into S3 when their sizes were big, and then create a version. This process takes a long time, and chances are high that you will make a defective layer when you’re using Windows or Mac because of some layers that compile binaries when you download them.
I wrote an article back in 2019 on how to do that with the help of Docker, and it still gets read, which triggers the need to create a new, simple, and extremely fast way to use this amazing feature: Lambda Layers.
