I'm working with a Flask and Peewee backend in Python and a Svelte frontend using TypeScript. I'm curious about the best strategies for ensuring type safety between the two. What methods or tools do you recommend to maintain a reliable connection and type consistency?

I've been using GraphQL for a couple of years, and it has improved the developer experience significantly. It helps manage changes in the backend while keeping the frontend in check. I also utilize GraphQL Codegen as part of the CI/CD process, which gives me precise types during development and type checks during deployment.
One effective approach is to generate an OpenAPI specification from your Flask backend. You can then use this spec to create corresponding TypeScript types for your Svelte frontend. This way, both sides will be in sync regarding the expected data structures.
