Feature request: OpenAPI support in Event Handler #4515
Description
Use case
As a customer, I want to enable OpenAPI schema generation when using Event Handler, similar to what described in the utility RFC and to what Powertools for AWS Lambda (Python) does.
Solution/User Experience
At this point is too early for us to suggest an API or a design beyond what already described in #3500.
As part of the issue pre-work we'll have to do a proof of concept and come up with a spec, before starting implementation.
When working on the design, we should also account for SwaggerUI generation although the implementation for this sub-feature will likely require its own issue/discussion.
Alternative solutions
Acknowledgment
- This feature request meets Powertools for AWS Lambda (TypeScript) Tenets
- Should this be considered in other Powertools for AWS Lambda languages? i.e. Python, Java, and .NET

Hi everyone, thanks for the interest in this feature - we're going to get together in the coming weeks to start creating a spec to see how it could be implemented and make a decision.
