Project mention: Next-generation web framework Teo, supports Node.js, Python and Rust | news.ycombinator.com | 2024-06-08

You would use OpenAPI (formerly Swagger) [1] for that, which includes JSONSchema for data types but also adds specs for defining REST apis. There are plenty of generators and other tools that work with OpenAPI [2]

Project mention: Creation and Usage of BOM in Gradle | dev.to | 2024-01-07

The issue is that the springdoc-openapi BOM brings an old version of the Spring Framework 6.0, which is incompatible with Spring Boot 3.2. There are several ways to solve this problem: update springdoc, change the order of BOM imports, but the best, in my opinion, is to avoid using the io.spring.dependency-management plugin.

Project mention: Why, after 6 years, I'm over GraphQL | news.ycombinator.com | 2024-05-30

It may not be an exact analog, but "swagger UI" for openapi is the best I've seen like GraphiQL. Example https://petstore.swagger.io/ . Not sure of other alternatives.

No analog for "subgraph federation systems", unless a load balancer will suffice.
