Learn the full potential of TypeScript by using advanced features like Type Inference, Type Guards, Generics, Transformers, and Utility Types with asynchronous programming in both Node.js (using Express.js) and Bun.js (using Hono.js), all while understanding best practices for building strongly typed APIs with different databases.
OverviewIn this workshop, we’ll kick off with a discussion on the recent updates in Node.js and Bun.js, focusing on their built-in TypeScript support. You'll learn how to set up TypeScript in both runtimes and create strictly typed APIs using Express.js and Hono.js. Through hands-on demos, we'll explore integration with various databases like MongoDB and Postgres, leveraging advanced TypeScript features to build robust applications. By the end of the workshop, you'll be equipped with the knowledge to optimize TypeScript code for performance and design patterns, ensuring your APIs are both efficient and maintainable.

Learning Goals- Introduction to Node.js’s and Bun.js’s TypeScript support- Advanced TypeScript Features: Generics, Type Guards, Mapped Types, etc.- Middleware and Dependency Injection with Express.js and Hono.js- Design Pattern and Performance Enhancements in TypeScript- Unit and Integration Testing with TypeScript- Database Integration: MongoDB, Postgres, Prisma, and others- Best Practices for Robust API Development in both Node.js and Bun.js

Learn widely used React patterns, including HOCs, Compound Components, Provider Patterns, Functions as Child, and Portals, to write cleaner, more efficient code and create scalable, maintainable applications.Overview In this workshop, viewers will learn about key React patterns that can make their code more efficient, readable, and maintainable. We'll introduce each pattern, explain how it works, and demonstrate practical examples. By the end of the session, participants will have a solid understanding of how to use these patterns in their projects.Learning GoalsHOCs Compound Components Provider Patterns Functions as Child Portals Modularity Maintainability Real-world Application.

Learn how to handle forms in React using the latest features, such as startTransition, useTransition, useOptimistic, and useActionState, with and without React 19 server actions, alongside proper validation, error handling, and best practices.
Overview The workshop will begin by demonstrating traditional form handling using useState and useEffect for client-side rendering. Gradually, we'll transition to using the latest React 19 features, including server-side forms and the newest hooks for managing form states and errors. By the end of the workshop, participants will understand how to create robust forms with proper validation and error handling.
