Vue Ecosystem Essentials: Build Modern Web Apps with Vue, Vuex, and Vue Router

Throughout the development of modern front-end frameworks, Vue has always been favored by developers for its ease of use, progressive nature, and high readability. The release of Vue 3 is not just a version upgrade, but a comprehensive evolution of framework design philosophy and engineering capabilities.

Vue 3 is no longer just "faster Vue," but a front-end framework redesigned for long-term maintenance, complex applications, and modern engineering systems. From the refactoring of reactive systems to the introduction of the Composition API, and deep integration with TypeScript and Vite, Vue 3 marks the Vue ecosystem's official entry into a more mature and professional stage.

"Vue3 Mastery：From Basics to Advanced App Development" is a systematic learning guide built around Vue 3's new capabilities and modern development models, helping developers start from basic syntax and gradually master Vue 3's core mechanisms, advanced modes, and best practices in real-world projects.

Why systematically learn Vue 3?

Many developers encounter the following problems when using Vue 3:

• Able to write components, but don't understand the design intent of the Composition API.
• Know how to use ref and reactive, but don't understand how reactive systems work.
• Projects become difficult to maintain as they grow, with scattered logic and bloated components.
• Incomplete understanding of the differences between Vue 3 and Vue 2.

Don't know how to organize state, logic, and architecture in large projects.

The difficulty in learning Vue 3 lies not in the number of APIs, but in the shift in mindset.

The goal of this book is to help you advance from "writing Vue 3" to "designing applications with Vue 3".

Overall Learning Path of This Book

This book follows a learning path from simple to complex, from surface to core, from syntax to architecture, and is divided into six stages:

• Vue3 Design Philosophy and Basic Syntax
• Template System and Component-Based Development
• Composition API and Logic Reuse
• Reactive Systems and Operating Mechanisms
• Engineering, Performance Optimization, and Ecosystem Integration
• Large-Scale Projects and Advanced Application Patterns

Each part is closely integrated with real-world development scenarios, avoiding theoretical piling up that is detached from reality.

Stage One: Vue3 Core Concepts and Quick Start

Before starting to code, this book will first guide you to understand:

• The development history of Vue and the design goals of Vue3
• The core changes in Vue3 compared to Vue2
• Application examples, template syntax, and directive system
• Reactive data and basic component development
• The structure and specifications of Single-File Components (SFCs)

This will help you build a comprehensive cognitive framework for Vue3.

Phase Two: In-depth Understanding of Component Systems and Template Capabilities

Components are the core of Vue applications:

• Component communication (Props / Emits / Slots)
• Dynamic and asynchronous components
• Lifecycle and composition logic
• Template compilation and rendering process
• Common component design patterns

Learn to build a clear and maintainable component system.

Phase Three: Composition API and Logical Abstraction

The Composition API is the soul of Vue 3:

• setup function and execution timing
• The essence of ref, reactive, computed, and watch
• Custom composition functions (Composables)
• Logic reuse and separation of concerns
• Collaboration between the Composition API and the Options API

Help you truly master advanced development paradigms of Vue 3.

Phase Four: Reactive Systems and Operating Mechanisms

Delving into the "Black Box" of Vue3:

• Proxy and Reactive Tracing Mechanisms
• Effects, Dependency Collection, and Update Triggering
• Virtual DOM and Diff Strategies
• Rendering Optimization and Batch Update Processing
• The Underlying Reasons for Vue3's Performance Improvements

Understanding why Vue3 is fast and where its speed comes from.

Phase Five: Engineering Practices and Ecosystem Integration

Vue3 is an engineering-first framework:

• Vue3 + Vite Build System
• Best Practices for TypeScript in Vue3
• Routing, State Management, and Module Decomposition
• Style Schemes and Component Library Design
• Performance Optimization and Bundling Strategies

Helping you build Vue3 projects that conform to modern front-end standards.

Phase Six: Advanced Patterns and Large-Scale Project Practice

From Small Projects to Complex Systems:

• Application Architecture Design and Module Boundaries
• Business Logic Layering and State Management Strategies
• Testability and Maintainability Design
• SSR, Cross-Platform Development, and Future Evolution Directions
• Practical Experience with Vue3 in Enterprise Projects

This book will equip you with the ability to build long-term evolving applications using Vue3.

Who is this book for?

This book is suitable for:

• Front-end developers (Vue beginner/intermediate/advanced)
• Engineers migrating from Vue2 to Vue3
• Those who want to gain a deeper understanding of framework principles
• Team members who need to build medium to large-scale front-end applications

If you are not satisfied with simply "being able to write Vue3" but want to truly understand and effectively use Vue3, this book will be a long-term, systematic guide for you.
