as a heavy user of CDK, sst looks pretty cool.

i'm curious why you didn't go the direction of adding this functionality to CDK directly? i'd like to use some of the functionality in here like live lambda development, but i also don't want to take on converting my org's already built CDK extensions and deal with migrations.

Thanks!

We had to change the build process of Lambdas to support deploying a mock version of the function. And we need to add a new command that deployed the debug stack.

Here's how it works internally — https://docs.serverless-stack.com/live-lambda-development

Your existing CDK app should work with SST. The main difference is that SST deploys per stage (or environment). This allows you to do `sst start` that goes to one environment and `sst deploy --stage prod` that goes to another.
