# Complex State Management in Next.js 13+ with Server and Client Components
_Sharing and managing state between server and client components is not trivial_, especially with the limited 
information available online. This course will take you through all the basics you need to answer the question:

> How do I share state between server and client components in Next.js?

## Module 1: Intro & Getting Started
_Begin your journey by understanding the essentials of Next.js 13+ and state management._

- **Overview**: Get an introduction to the core principles and concepts of Next.js 13+. Familiarize yourself with the course structure, the instructor's background, and the tools you'll be using.
- **Goals**: Set clear expectations about what the course will cover, including fundamental problems related to state sharing between server and client components.

## Module 2: State
_Understanding the heart of React applications: state._

- **General Concept of State**: Dive into what state really means in the context of web applications. Explore how state affects the design and functionality of your app.
- **Local vs Global State**: Master the differences and applications of both local and global state to make informed decisions in your coding practice.
- **Management Techniques**: Get to grips with various strategies and tools for managing application state, including popular third-party libraries.

## Module 3: Client Components
_Dissect Client Components and unravel their role within Next.js._

- **Component Structure**: Break down the anatomy of client components, learning how to create them and understanding their role within the application.
- **Capabilities and Limitations**: Examine what client components can do, understanding their scope and limits, and what is reserved for server components.
- **Proper Utilization**: Develop a keen sense for the appropriate use of client components, paying special attention to interactivity and dynamism. Wrap up with a quiz to reaffirm your knowledge on client components.

## Module 4: Server Components
_Unveil the capabilities and edge of using Server Components in Next.js._

- **Understanding Server Components**: Define what server components entail and their architecture, emphasizing state-related functions and limitations.
- **Contrasting with SSR**: Compare server components to traditional server-side rendering and understand when and why server components offer an advantage.
- **Best Practices**: Learn to discern when it's most appropriate to use server components, and explore the "server-land" where certain server-side actions take place. A checkpoint with a pop quiz will round up the module, cementing your understanding of server components.

## Module 5: Page Architecture
_Review and refine the structures that make up your Next.js applications._

- **Maximizing Performance and Simplicity**: Explore the design patterns that allow you to make the most of Next.js features, leading to optimized performance and simplicity in your project structure.
- **Practical Application**: This module revisits the concept of page architecture, providing more complex and practical examples of how to partition components for scalability and maintainability.

## Module 6: Sharing State between Client and Server Components
_Integrating the dual realms of Next.js, bringing together server and client component state management._

- **Identifying the Problem**: Delve into the nuances of managing and sharing state in server components, identifying when it differs from client-side state management.
- **Cross-Component Communication**: Learn how to efficiently pass state and props between server and client components.
- **Working with Cookies and HTTP Requests**: Gain hands-on experience with cookies as a mechanism for shared state, and leveraging HTTP requests to sync state across the server-client divide.

_By the end of this course, participants will acquire a comprehensive understanding of managing state within Next.js 13+ applications, effectively using both the server and client components to build robust, scalable, and maintainable web applications._

 is essential for data that multiple components within your application need to access or manipulate. This could be anything from user authentication status to a theme applied across your application. Unlike local state, global state isn't confined within one component but spans across several, often necessitating either a common ancestor or a state management library or architecture. 
This state is crucial when different parts of your app need to react to the same data.

However, most developers tend to overuse global state or use it incorrectly, leading to sub-optimal architectures. For instance, without using the Context API or a third-party library, developers often resort to 

, which involves passing down props from parent components to child components down the hierarchy. This approach can lead to tightly coupled components that should otherwise be independent, resulting in an architecture that's hard to maintain and scale.

# Understanding State Management in React: A Comprehensive Guide to Global State and Context API

## Introduction

In software development, managing state is a critical task, particularly when dealing with complex applications. This lesson aims to provide a comprehensive guide to state management in React, with a focus on handling `global state` and using `Context API`. 

We will unravel the intricacies of maintaining global state, delve into the potential pitfalls associated with bad practices, and demonstrate how the React Context API can be used efficiently to channel global state across your application.

## Understanding Global State

`Global state` is essential for data that multiple components within your application need to access or manipulate. This could be anything from user authentication status to a theme applied across your application. Unlike local state, global state isn't confined within one component but spans across several, often necessitating either a common ancestor or a state management library or architecture. 
This state is crucial when different parts of your app need to react to the same data.

However, most developers tend to overuse global state or use it incorrectly, leading to sub-optimal architectures. For instance, without using the Context API or a third-party library, developers often resort to `prop drilling`, which involves passing down props from parent components to child components down the hierarchy. This approach can lead to tightly coupled components that should otherwise be independent, resulting in an architecture that's hard to maintain and scale.
