🚀 What You’ll Learn

This repo helps you understand how to choose the right state approach based on:

• Component hierarchy
• Hosting model (Server / WebAssembly / Web App)
• Data lifetime
• Performance considerations
• Scalability needs

📘 Examples Overview

1️⃣ URL/Query String Parameters

• Making state bookmarkable and shareable.

📁 Folder: url-query-string-parameters

---

2️⃣ Local Component State

• Simple UI-only state confined to a single component.

📁 Folder: local-component-state

---

3️⃣ Parent-Child Communication

• Passing data and events between related components.

📁 Folder: parent-child-communication

---

4️⃣ Sharing State Down the Tree: Cascading Parameters and Values

• Sharing data across deep component trees without prop drilling.

📁 Folder: sharing-state-down-the-tree

---

5️⃣ Global State with Dependency Injection Services

• Sharing state across unrelated components and pages.

📁 Folder: global-state-with-di-services

---

6️⃣ Prerendered State Persistence

• Maintaining state during SSR → interactive transitions.

📁 Folder: prerendered-state-persistence
