Top 18 TypeScript type-safety Projects

  • ts-toolbelt

  • pgtyped

    pgTyped - Typesafe SQL in TypeScript

    • Project mention: Type-Safe Printf() in TypeScript | news.ycombinator.com | 2024-03-24

    There is an implementation of SQL that operates on a table shaped type, entirely at type level. For your amusement: https://github.com/codemix/ts-sql

    There are a bunch of more practical takes that codegen types from your database and generate types for your queries, eg: https://github.com/adelsz/pgtyped

    To me the second approach seems much more pragmatic because you don’t need to run a SQL parser in a fairly potato interpreter on every build
