Vue.js is one of the most popular JavaScript frameworks for building dynamic and interactive web applications. To master Vue.js, it is important to approach learning step by step, focusing on different subjects that build from the basics to advanced topics. Each subject requires a balance of skill set (what you can do), knowledge (what you should know), understanding (how it works internally), and usage levels (where to apply it in real projects). The following breakdown gives a subject-wise roadmap for Vue.js learners.
Vue.js Learning – Subject-wise Skill & Knowledge Levels
Basics of Vue.js

Usage Level: Beginner – Foundation level
Components
Skill Set: Reusable components, props, emit events
Knowledge: Communication, slots, dynamic components
Understanding: Lifecycle & hierarchy
Usage Level: Beginner → Intermediate
Reactivity System
Skill Set: ref, reactive, watchers
Knowledge: Options API vs Composition API
Understanding: Vue’s reactivity tracking
Usage Level: Intermediate
Vue Router
Skill Set: Configure routes, navigate programmatically
Knowledge: Nested routes, params, query strings
Understanding: History vs hash mode
Usage Level: Intermediate
State Management (Vuex/Pinia)

Understanding: CI/CD pipelines
Usage Level: Advanced
Learning Vue.js is a journey that moves from basics and components to advanced topics like state management, testing, and performance optimization. Beginners should focus on core reactivity, forms, and routing, while advanced learners should explore Composition API, global state, and deployment strategies. By mastering both theoretical knowledge and practical usage, developers can confidently build everything from small projects to enterprise-level applications with Vue.js.
