React Advanced Training in Ireland

This immersive 5-day course equips developers with best practices in modern React development through a series of project-based learning experiences. Learners will build real-world applications while mastering advanced React techniques, including hooks, state management, routing, and performance optimisation.

Participants will learn how to structure scalable React applications, apply key design patterns, and implement robust solutions using the latest tools and libraries such as Redux Toolkit, React Query, and Firebase Authentication. The course balances hands-on development with practical demonstrations and expert guidance, ensuring learners leave with applied skills ready for immediate implementation in professional environments.

Key focus areas include best practice component design, application state management, routing strategies, optimising performance, and deploying real-world applications.

Participants should have:

• Working knowledge of JavaScript fundamentals and ES6+ syntax
• Practical experience developing basic React applications
• Familiarity with HTML, CSS, and modern front-end tooling (e.g., npm, Vite)
• Comfortable using Git and VS Code (recommended)

Target audience

This course is designed for:

• Front-end and full-stack developers looking to deepen their React expertise
• Developers seeking to apply React best practices to production applications
• Teams aiming to create scalable, maintainable, and performant React codebases

By the end of this course, learners will be able to:

• Build modular and reusable React components following industry best practices
• Implement effective state management solutions using Context API, Redux Toolkit, and React Query
• Apply React Router v6+ for advanced client-side routing, including protected routes and nested layouts
• Optimise React application performance using memoisation and best practice rendering patterns
• Integrate third-party libraries for form handling, API interactions, and authentication
• Develop, deploy, and test project-based applications simulating real-world scenarios
• Identify and avoid common anti-patterns in React development
• Utilise GitHub Copilot and modern developer tools to streamline coding workflows
