Type safety from the database to the frontend
summary
A library at databases generates TypeScript from SQL schemas and PG typed links query strings to precise result types so schema changes update types automatically. Codegen for GraphQL via graphql code gen and small custom generators for Rust and translations produce matching client and server types. Runtime parsing and serialization come from fun types and fun types schemas, and TS reset forces JSON to be validated. Demos show generators and runtime checks working end to end.
