FRONTEND S06 L14 React Context (Sharing State Across Components)

📘 REACT CONTEXT — SHARING STATE ACROSS COMPONENTS In this lesson, we implement React Context to share state across multiple component levels without passing props through each intermediate component. You will create a context provider, move shared state into it, and consume that shared state directly in child components. 🎯 IN THIS VIDEO Review why prop drilling becomes difficult in deeper component trees Create a context using React createContext Wrap app content with a provider component Move shared counter state into the provider Provide shared values through the provider value property Consume shared state in child components using useContext Replace prop-based counter and callback wiring with context consumption Verify that banner and button stay in sync through shared context state 🚀 HOW TO USE THIS COURSE React Context is ideal when many related components need the same shared data. It reduces repetitive prop passing and keeps component interfaces cleaner as your app grows. 👉 Course Website: www.richardbraycourses.co.uk 👉 Course Repositories: www.github.com/RichardBrayCourses 👉 Full course playlist: https://youtube.com/playlist?list=PLNlOxdq7xu14b5ewH4IJC9tMinkgZBuVR&si=Pg8pEDR5UUbQstz6 📂 SECTION REPOSITORY Section 6 repository: https://github.com/RichardBrayCourses/frontend06-react 💡 NOTE Use Context for broadly shared state, while keeping local component-only state inside the component where it is used.
