I'm working with a Flask backend using Peewee and a Svelte frontend with TypeScript, and I'm trying to figure out the best ways to ensure type safety between the two. Any tips on strategies or tools to consider?

One great approach is to generate an OpenAPI specification from your Flask backend. You can then use that spec to create matching TypeScript types for your Svelte frontend. This way, you ensure both sides are in sync with the types they expect.
We've had success using Swagger and OpenAPI. Our backend generates the spec, and we have a code generator that creates TypeScript models for the frontend. It keeps everything aligned even though I might not fully understand how it works! 😂
Exactly! It’s a game-changer for consistency.
