Build End-to-End TypeScript Apps

In this advanced one-day workshop on TypeScript, you will learn to harness the power of typing at all levels of an application—from the frontend to the backend on Node.js—with a single source of truth in types.

We will explore real scenarios:

• step-by-step database migrations,
• API versioning without the risk of breaking existing clients,
• safe integration of third-party services using typed wrappers.

You will master advanced TypeScript patterns - from decorators to discriminated unions, and learn to build reliable pipelines with automated testing and deployment to catch hidden typing errors before reaching production.

During the workshop, you will learn to:

• Combine client and server types to eliminate runtime errors
• Apply complex patterns: generics, decorators, mapped types
• Build end-to-end validation using Zod or tRPC
• Implement strategies for API versioning and migration, maintaining backward compatibility
