An alternative to this and Apollo codegen is GraphQL Code Generator[1]. Like codegen it takes the opposite approach by generating typescript from graphql. It's similar to codegen, with the main two differences being 1) it's not centered around queries, it will generate types for all schema parts as well as queries defined client-side. This is useful for getting typescript types for all the individual schema parts without being "wrapped" in the type of a query, and 2) it's template based and relatively easy to extend modify how the code is generated.

We use graphql-code-generator to make Typescript. We also upload versions of our typescript-query files (written separately from other client TS code) for each published version/branch (e.g. 1.1, 1.2, dev) and then can use an eslint plugin on the graphql server to validate it doesn't break backwards compatibility with existing client-side code (unless intentional). This has definitely saved us more than once.

Sounds great. Thanks for sharing!
