2.4 Creating a New Vue App

With Vue CLI in place, generating a new Vue.js project is a breeze. Executing simple commands sets the foundation for your venture into the realm of Vue.js development.

2.5 Development Server Launch

Navigate to your project directory and launch the development server to witness your Vue.js project in action. The local server, stationed at provides a live preview of your creation.

2.6 Exploring HelloWorld.vue

Immerse yourself in the development process by tweaking the HelloWorld.vue file. Witness real-time changes on the website, celebrating the successful setup of your inaugural VueJS project.

3. Decoding the Vue Folder Structure

In a Vue.js project, navigating through the various files and folders is crucial. This section unveils the key components of the Vue folder structure, providing insights for both beginners and those familiar with React-like libraries.

3.1 Public Folder

Dedicated to static files essential for your application, the public folder houses images, fonts, and videos, ensuring seamless integration of necessary assets.

3.2 Src Folder

Functioning as the project’s root, the src folder encompasses critical subfolders, each serving a distinct purpose.

3.2.1 Components

Serving as the building blocks of Vue.js, the components folder encapsulates the logic for diverse elements such as headers, banners, footers, and sidebars.

3.2.2 Assets

Containing images, fonts, and global resources, the assets folder acts as a repository for essential elements utilized throughout the application.


Home to top-level views, the views folder corresponds to each component, responsible for rendering the main content of respective pages.

3.2.4 Configuration Files

Various configuration files, including package.json and webpack.config.js, play pivotal roles in defining dependencies and configuring the build process.

As you acquaint yourself with the intricacies of Vue.js project structure, the pathway to constructing intricate applications becomes clearer.

4. Features Galore: Unraveling VueJS Attributes

VueJS boasts an array of features that contribute to its popularity among developers. These attributes are instrumental in enhancing productivity, making VueJS a formidable tool in the arsenal of web developers.

4.1 Virtual DOM

Vue.js leverages a virtual DOM, a replica of the real DOM represented through JavaScript data structures. This mechanism expedites changes to the DOM, ensuring efficient rendering and subsequently enhancing overall performance.

4.2 Two-Way Data Binding

Facilitating seamless communication between the user interface and underlying data, two-way data binding ensures that changes made in the UI reflect in the data, and vice versa. This feature, rooted in the MVVM architecture, distinguishes Vue.js from libraries like React.js.

4.3 Template System

Vue.js employs a declarative template system for defining the structure and content of the user interface. This system, resembling HTML, supports data binding, conditional rendering, iteration, event handling, and interpolation, providing a versatile approach to UI development.

4.4 Routing

Embedded with a built-in router, Vue.js simplifies the creation of multi-page websites that emulate the seamless experience of a single-page application. The router enables URL mapping, allowing smooth transitions between pages without full reloads.

4.5 Components in Vue.js

Components form the bedrock of Vue.js, serving as reusable UI elements that contribute to a modular and maintainable codebase. These components exhibit characteristics such as reusability, encapsulation, composition, customization, event handling, and lifecycle hooks.

5. VueJS Best Practices: Navigating the Development Landscape

While Vue.js provides flexibility in its usage, adhering to industry best practices ensures the creation and maintenance of an organized codebase. These practices, gleaned from seasoned developers, offer guidance for a structured Vue.js development journey.

5.1 Embrace Components

Given Vue.js’s foundational emphasis on components, adopting a component-based approach streamlines code management. Dividing the code into smaller, reusable components enhances maintainability.

5.2 Leveraging Computed Properties

In lieu of methods, incorporating computed properties enhances functionality. These properties reevaluate only when their dependencies change, contributing to optimized application performance.

5.3 Shun Direct DOM Manipulation

Vue.js champions a declarative approach to binding data to the DOM, discouraging direct DOM manipulation with JavaScript. This practice fosters cleaner and more maintainable code.

5.4 Vuex for State Management

For applications with intricate state management requirements, embracing Vuex, a state management library for Vue.js, proves advantageous. Vuex centralizes the state, easing the management of complex application states.

5.5 Avert Mutating Props

Respecting the unidirectional flow of data in Vue.js, avoiding the mutation of props in child components fosters code clarity. Consistent adherence to this principle aids in comprehending and maintaining code.

5.6 Embrace Async Components

In scenarios where components entail prolonged loading times, the use of async components proves beneficial. These components enable lazy-loading, enhancing overall application performance.
