TypeScript Best Practices

Priority: P1 (OPERATIONAL)

Implementation Guidelines

• Naming: Classes/Types=PascalCase, vars/funcs=camelCase, consts=UPPER_SNAKE. Prefix I only if needed.
• Functions: Arrows for callbacks; regular for exports. Always type public API returns.
• Modules: Named exports only. Import order: external → internal → relative.
• Async: Use async/await, not raw Promises. Promise.all() for parallel.
• Classes: Explicit access modifiers. Favor composition. Use readonly.
• Types: Use never for exhaustiveness, asserts for runtime checks.
• Optional: Use ?:, not | undefined.
• Imports: Use import type for tree-shaking.
