Getting Started with Next.js 14 App Router

## Introduction Next.js 14 introduced significant improvements to the App Router, making it the recommended way to build new Next.js applications. ## Key Features - **Server Components by default** — Components are server-rendered unless you opt into client-side rendering with `"use client"`. - **Layouts and Templates** — Share UI between routes with persistent layouts. - **Loading and Error States** — Built-in support for streaming and error boundaries. - **Route Handlers** — API routes using the Web Request/Response API. ## Getting Started Create a new project: ```bash npx create-next-app@latest my-app ``` The App Router lives in the `app/` directory. Each folder represents a route segment, and `page.tsx` files define the UI for that route. ## Conclusion The App Router is a powerful paradigm shift that brings React Server Components to the mainstream.
