Using React Context API in Next.js 15 for Global State Management
In modern Next.js applications, state management is essential for maintaining global UI states like modals, sidebars, and theme toggles. While Redux and Zustand are powerful options, React Context API is a lightweight and built-in solution for simpler global states. In this guide, we’ll build a global state manager in Next.js 15 using Context API and TypeScript, with a custom hook for seamless usage. Step 1: Create a Context for Global State We start by creating a StateContext to manage a simple open state (e.g., for a modal or sidebar):
