Spécialisation Modern Web Development with TypeScript

This course introduces you to the power of Object-Oriented Programming (OOP) in TypeScript, enabling you to design scalable, reusable, and type-safe applications that follow modern software engineering best practices. You’ll learn how to apply OOP principles—encapsulation, inheritance, abstraction, and polymorphism—while leveraging TypeScript’s advanced type system to create professional-grade codebases.

Through interactive lessons and hands-on coding projects, you’ll practice building classes, implementing inheritance, designing with abstract classes and interfaces, applying decorators, and using advanced type features like utility types, conditional types, and type guards. By combining OOP principles with TypeScript’s strong typing, you’ll gain the skills to write cleaner, safer, and more maintainable applications. By the end of this course, you will be able to: - Implement classes, access modifiers, static members, and readonly properties in TypeScript - Apply inheritance, method overriding, abstract classes, and interfaces to design extensible systems - Differentiate between abstract classes and interfaces and use them effectively in real-world projects - Enhance your applications with decorators, type inference, unions, intersections, and narrowing - Use advanced type system features such as utility types, conditional types, mapped types, and type guards - Design and deliver a complete TypeScript project that demonstrates mastery of OOP and advanced type features This course is ideal for JavaScript and TypeScript developers who want to deepen their expertise and build structured, maintainable applications using OOP principles and advanced TypeScript features. A solid understanding of TypeScript fundamentals (variables, functions, basic types) is recommended before starting this course. Join us to master Advanced TypeScript with OOP and take your development skills to the next level with robust, enterprise-ready application design.

This course explores how to build modern frontend applications using React with TypeScript, combining strong typing with practical UI development. Designed for developers who want to go beyond the basics, it demonstrates how TypeScript ensures safer, more scalable, and maintainable React applications by catching errors early and enforcing consistency across components, hooks, and APIs.

Through hands-on lessons and guided demonstrations, you’ll learn to configure React projects with TypeScript, implement typed components, and apply type safety to props, state, and lifecycle methods. You will also explore React hooks in depth, including custom and advanced hooks, and extend type safety into forms, event handling, and styling with UI libraries such as Material UI, Chakra UI, and Styled Components. The module culminates in building a fully typed task manager app that demonstrates how these concepts come together in practice. By the end of this course, you will be able to: - Set up and configure React projects with TypeScript for scalable development. - Build strongly typed class and functional components with props, state, and lifecycle methods. - Apply TypeScript to core, custom, and advanced React hooks (useState, useEffect, useRef, useReducer, etc.). - Implement event handling and form validation with strict type checking. - Integrate UI libraries and styling frameworks with TypeScript for production-ready design. - Develop and deploy a type-safe React application that demonstrates real-world best practices. This course is ideal for JavaScript and React developers who want to strengthen their frontend skills with TypeScript. A working knowledge of React will be helpful, but no prior experience with TypeScript is required. Join us to master type-safe frontend development and learn how TypeScript transforms React applications into cleaner, more reliable, and enterprise-ready solutions!

This course provides a guide to building backend systems with Node.js and TypeScript, combining strong typing with modern server-side practices. It demonstrates how TypeScript improves reliability, security, and scalability in backend projects by enforcing type safety and consistency across routes, middleware, databases, and authentication flows.

Through hands-on lessons and real-world demonstrations, you’ll start by setting up Node.js projects with TypeScript, configuring linting, formatting, and logging tools. You will then learn to build secure and maintainable servers using Express, define typed APIs and middleware, and implement error handling patterns. The course progresses to integrating MongoDB with Mongoose, where you’ll create typed schemas, models, and perform CRUD operations with validation, indexing, and transactions. Finally, you’ll explore authentication with JWTs, role-based access control (RBAC), and automated testing with Jest to ensure backend reliability. By the end of this course, you will be able to: Initialize and configure Node.js projects with TypeScript, ESLint, Prettier, and strict compiler settings. Build Express servers with typed routes, middleware, error handling, and APIs. Design and validate MongoDB schemas and models with Mongoose in TypeScript. Perform CRUD operations, query optimization, and transactions with strong typing. Implement secure authentication using JWTs and enforce role-based access control. Write unit and integration tests with Jest to validate controllers, routes, and database operations. Develop a production-ready backend system where TypeScript ensures maintainability, security, and long-term scalability. This course is ideal for JavaScript and Node.js developers who want to strengthen their backend skills with enterprise-level TypeScript practices. A solid understanding of JavaScript, Node.js basics, and OOP in TypeScript is recommended before starting. Join us to master backend development with TypeScript and learn how to design secure, scalable, and production-grade APIs!
