We went into another direction, leveraging the existing ecosystem instead of re-inventing the wheel. Although I appreciate the effort of improving the DX for REST APIs, I think the OpenAPI ecosystem is very strong and established. Contrary to this approach, we (https://WunderGraph.com https://WunderGraph.com) ingest one or more OpenAPI and GraphQL apis and combine them into a backend for frontend. We have code generators for all major frontend frameworks, like react, svelte, Vue, solid, astro, etc... These don't just make calling APIs type-safe but also handle authentication, etc... The BFF approach allows us to securely inject API keys or add a middleware using Typescript. I'm curious what people think of this approach. Our users don't usually integrate one or two APIs but rather 20 or more. I guess it would be quite expensive if you had to write a custom specification for each service.
