v3.18.0

Summary

This release adds support for files media types in our OpenAPI utility. We also improved our Parser utility by adding new models for AppSync Events.

⭐️ Congrats to @​oyiz-michael and @​sdangol for contributing to this project for the first time!

Working with form data

Docs

You can use the Form type to tell the Event Handler that a parameter expects form data. This automatically sets the correct OpenAPI schema for application/x-www-form-urlencoded requests.
