Summary

The frontend manually maintains API call code that can drift from the backend. Auto-generating the TypeScript client from the FastAPI OpenAPI spec would keep types in sync automatically.

Work to do

  • Add a script (e.g., using openapi-typescript or @hey-api/openapi-ts) that fetches the FastAPI /openapi.json and generates a typed TypeScript client.
  • Add the generated client to the frontend source (or generate it at build time).
  • Replace manual fetch/axios calls in the frontend with the generated client where practical.
  • Add the generation step to CI so drift is detected.

Acceptance criteria

  • Running the generation script produces a typed TypeScript client with no manual edits needed.
  • Frontend compiles without type errors using the generated client.
  • CI fails if the generated client is out of date with the current spec.

Already resolved. openapi-typescript is in devDependencies. npm run generate and npm run generate:local scripts exist. CI checks that src/api/schema.d.ts is up-to-date (build.yaml lines 42-48). PR #63 and PR #443. Closing.
