Training program

Module 1Advanced TypeScript Types: Unions, Intersections, and Mapped Types (tsconfig, VS Code)

Dive into TypeScript 2026 new features by setting up an intermediate project via tsconfig.json, explore conditional unions and intersections to model complex enterprise data, practical exercises on refactoring existing JS code, create your first custom mapped types, typed unit tests with Jest to validate skills immediately and produce a functional deliverable.

Module 2Generics and TypeScript Utilities: Parameterized Functions and Classes (Debugging Tools)

Master advanced generics in TypeScript 2026 for reusable team components, implement utility types like Partial, Pick, and Omit on concrete enterprise API cases, develop generic classes for scalable collection management, debug with TypeScript Language Server in VS Code, complete an exercise for a full utility library with code review to boost professional skills.

Module 3TypeScript Integration: React and Node.js (Webpack, ESLint, ts-node)

Seamlessly integrate TypeScript 2026 into React for high-performance typed interfaces, configure a Node.js project with ts-node and ESM modules, manage typed props and hooks on a real enterprise case like an admin dashboard, optimize bundling with Webpack and ESLint for code compliance, build and test a hybrid full-stack app, obtain a production-ready deployable prototype.

Module 4TypeScript Error Handling and APIs: Typed Fetch, Zod (Middlewares, Validation)

Develop infallible error handling with discriminated types in TypeScript 2026, integrate Zod for runtime validation of enterprise APIs, create typed middlewares for Express.js, simulate fetch calls with complete typed responses, handle failure cases like timeouts or 404s with error unions, produce a robust tested API module that directly enhances professional projects.

Module 5TypeScript Deployment and Migration: CI/CD, Docker (GitHub Actions, Vercel)

Finalize training with a progressive migration from JS to TypeScript 2026, set up CI/CD pipelines with GitHub Actions for typed builds, containerize with Docker for scalable enterprise deployments, optimize tsconfig for multi-environment production, deploy on Vercel with typed monitoring, synthesize via a complete red thread project, receive certification and resources for immediate professional application.
