Introduction to Global State and Context API
Explore the challenges of prop drilling in large React applications and learn how global state management using the Context API can simplify data sharing. Understand creating and using context, and how it helps maintain clean, scalable component architecture by providing shared data access without excessive prop passing.
As applications grow in size, managing data across deeply nested component trees becomes increasingly complex. Passing data through multiple layers of components, even when those components do not directly use it, introduces unnecessary coupling and complexity. This problem is known as prop drilling. This lesson builds a mental model for global state, explains why prop drilling becomes a problem, and explores how the Context API provides a clean solution.
Problem: Prop drilling in large component trees
In small applications, passing props from parent to child is simple and effective. However, as the component tree grows deeper, we often pass props through multiple intermediate ...
