Philosophy

All LSSM libraries follow these principles:

  • Type Safety First: Full TypeScript support with strict types.
  • Modular: Use only what you need, tree-shake the rest.
  • Platform Aware: Optimized for both Web and Native where applicable.
  • Single Source of Truth: Avoid duplication between layers (REST, GraphQL, Zod).
  • Developer Experience: Clear APIs, comprehensive docs, and helpful error messages.
