Typescript refactor

[justinvdm]

Highlights

• api and web are now fully typescript
• this means ts type definitions are now exposed - so ts-based redwood projects should get type safety and autocompletion when they use redwoodjs-stripe
• ts type definitions are generated from graphql queries and schema definitions, and used internally by redwoodjs-stripe/{api,web} for typechecking

Lower level context

• the build scripts were changed such that they'll include the necessary codegen steps and type definitions building steps
  • we still generate runtime code the same way, and only use tsc for generating the type definitions
• there are a bunch of changes and additions needed to the sdls to get the data to be compatible with what the stripe sdk is expecting
• we do a bunch of null/undefined parsing when receiving data from the graphql api client side and providing it to the stripe sdk to fix types
  • for objects, if the value is null or undefined, we omit the corresponding property
  • for arrays, we filter out nulls
• ideally what we need, is to generate the sdl types from stripe's own api types that they provide - this will probably mean we'll be able to avoid both further handwritten sdl maintenance, and this ^ parsing layer.
  • before investing time into that, probably first worth waiting out what happens with redwood's move to react server components (e.g. in case graphql is phased out of redwood)
