Master Next.js 15 & TypeScript – Setting Up Theme Provider (Dark Mode + Custom Themes)

🔥 In Part 4 of the Next.js 15 & TypeScript Masterclass, we implement a flexible theme provider to enable light/dark mode and custom theming in our app. You’ll learn how to manage themes using shadcn/ui utilities and create a user-friendly, accessible design system.

✅ What you’ll learn in this video:
✔️ Installing and configuring a global Theme Provider in Next.js 15
✔️ Enabling light/dark mode switching with shadcn/ui and Tailwind CSS
✔️ Persisting user theme preferences using cookies or local storage
✔️ Structuring the provider using the new App Router layout system
✔️ Creating custom themes and extending the Tailwind config
✔️ Ensuring accessibility and performance in theme toggling
✔️ Using icons and components that respond to the current theme

💡 Why Theme Providers Matter:
🔹 Enhances UX with personalized visual settings
🔹 Encourages good design patterns through component theming
🔹 Promotes scalability with centralized style control
🔹 Users expect dark mode—it’s no longer optional in modern apps
