Project mention: How to Automatically Consume RESTful APIs in Your Frontend | dev.to | 2024-01-25

Since the OpenAPI specification is language-agnostic, we can use the output to validate data in both our frontend and backend. This approach makes total sense since we can provide uniform validation rules on both sides of our stack. There are a few libraries out there that can help us with this task, such as typed-openapi or openapi-zod-client, which can take an OpenAPI definition as an input and transform it to zod schema definitons.
