    Project mention: when should I use api-gateway aws vs self written nodejs api | | 2023-02-24

    Does anyone have any success with API Gateway/Lamba for local environment with hot-reloading? I was playing around with “sam local start-api” a few weeks ago with along with CDK but it doesn’t seem like hot-reloading is supported, and need to manually restart for code changes to reflect, which is currently stopping me from trying out the API Gateway/Lamba combo further due to inefficient DX. Here’s a GitHub issue about it:
