Core Conventions

Client-Server Communication

• Prefer tRPC with React Query for fullstack projects (when the server and client are in the same package). See bun-trpc-setup.
• Otherwise prefer GraphQL. See bun-graphql-setup.

TypeScript

• Never use @ts-ignore
• Never use as any casting or as unknown as <some-other-type>

Test Conventions

• Test files: foo.ts → foo.test.ts (same directory)
• Use describe/it API (not test)
