• Understanding Frontend Development:
  • What is frontend development?
  • Role of HTML, CSS, and JavaScript.
  • Introduction to modern JavaScript (ES6+).
• Introduction to Vue.js:
  • What is Vue.js? (A progressive JavaScript framework for building user interfaces).
  • Why choose Vue.js? (Approachability, performance, flexibility).
  • Vue.js ecosystem overview (Vue Router, Vuex, Vue CLI, etc.).
• Setting Up Your Development Environment:
  • Installing Node.js and npm/yarn/pnpm.
  • Using a code editor (VS Code is highly recommended with Vue extensions).
  • Introduction to the Vue CLI (Command Line Interface).
  • Creating a new Vue project using Vue CLI.
  • Understanding the project structure (`src`, `public`, `package.json`, etc.).
• Basic Vue Concepts:
  • Instances (`new Vue()`): The root of a Vue application.
  • Data Property: Defining reactive data.
  • Methods Property: Defining functions for the instance.
  • Computed Properties: Deriving values based on reactive data.
  • Watchers: Performing side effects in response to data changes.
  • Lifecycle Hooks: Understanding the stages of a Vue instance's life (created, mounted, updated, destroyed).

Section 2: Building User Interfaces with Vue.js

• Understanding Templates:
  • HTML-based templates with Vue directives.
  • Interpolation (`{{ }}`).
  • Raw HTML (`v-html`).
  • Attributes (`v-bind:` or `:`) for dynamic attributes.
  • Event Handling (`v-on:` or `@`) for listening to DOM events.
• Directives:
  • `v-model`: Two-way data binding for form inputs.
  • `v-if`, `v-else-if`, `v-else`: Conditional rendering.
  • `v-show`: Conditional display (using CSS).
  • `v-for`: List rendering (iterating over arrays or objects).
  • `v-bind`: Binding attributes dynamically.
  • `v-on`: Handling events.
  • `v-text`: Updating element's text content.
  • `v-html`: Updating element's inner HTML.
• Components:
  • What are components? (Reusable Vue instances with a name).
  • Global vs. Local components.
  • Single File Components (`.vue` files):
    • `<template>` section (HTML).
    • `<script> ` section (JavaScript).
    • `<style>` section (CSS - scoped).
  • Props: Passing data down from parent to child components.
  • Events (`$emit`): Communicating up from child to parent components.
  • Slots: Distributing content into child components.
• Styling in Vue:
  • Scoped CSS in Single File Components.
  • CSS Modules.
  • Using CSS preprocessors (Sass, Less, Stylus).
  • Styling with `v-bind` (dynamic styles).
  • Class and Style Bindings (`:class`, `:style`).
• Forms and Input Handling:
  • Using `v-model` with different input types (text, checkbox, radio, select).
  • Form validation (basic and using libraries).

Section 3: Advanced Vue Concepts and Ecosystem

• Component Communication:
  • Props Down, Events Up (PDEVU) pattern.
  • Event Bus (`$on`, `$emit`, `$off` - less recommended for complex apps).
  • Providing/Injecting dependencies.
  • Using Vuex for centralized state management.
• Vue Router:
  • What is Vue Router? (Official routing library for Vue.js).
  • Setting up routes.
  • Dynamic route matching.
  • Nested routes.
  • Programmatic navigation (`router.push`).
  • Navigation Guards (global, per-route, in-component).
• Vuex:
  • What is Vuex? (Official state management library for Vue.js).
  • Understanding the core concepts:
    • State (centralized data).
    • Getters (computed properties for state).
    • Mutations (synchronous state changes).
    • Actions (asynchronous operations that commit mutations).
    • Modules (organizing large stores).
  • Using Vuex in components (`mapState`, `mapGetters`, `mapMutations`, `mapActions`).
• Mixins and Custom Directives:
  • Mixins: Reusing component options.
  • Custom Directives: Adding custom behavior to DOM elements.
• Render Functions and JSX (Optional):
  • Programmatically creating VNodes (Vue's virtual DOM nodes).
  • Using JSX with Vue.
• Transitions and Animations:
  • Using the `` component for element transitions.
  • Using the `` component for list transitions.
  • Integrating with CSS animations and JavaScript hooks.
• Composition API (Vue 3):
  • Understanding the need for Composition API (better code organization, reusability).
  • `setup()` function.
  • `ref`, `reactive`, `toRefs`.
  • `computed`.
  • `watch`, `watchEffect`.
  • Lifecycle hooks with Composition API.
  • Composables (reusable logic functions).

Section 4: Working with APIs and Asynchronous Operations

• Fetching Data:
  • Using the Fetch API or Axios (popular library) to make HTTP requests.
  • Handling asynchronous operations with `async`/`await`.
  • Displaying loading states.
  • Handling errors.
• Integrating with Backend APIs:

  • Working with JSON data.
  • Implementing authentication and authorization (tokens, cookies).
• Real-time Communication (Optional):
  • Using WebSockets or libraries like Socket.IO for real-time updates.

Section 5: Tooling, Build Process, and Deployment

• Vue CLI:
  • Creating projects with different presets.
  • Using plugins.
  • Configuring the build process (`vue.config.js`).
• Webpack (Under the Hood):

  • How Webpack bundles Vue applications.
• Code Splitting and Lazy Loading:
  • Improving performance by splitting code into smaller chunks.
  • Lazy loading components and routes.

  • Unit Testing (using Jest or Mocha).
  • Testing components with Vue Test Utils.
  • End-to-End (E2E) Testing (using Cypress or Nightwatch.js).

• Performance Optimization:
  • Keying `v-for` lists.
  • Component registration strategies.
