Installing Vue project and file structure

(1) Setting Up a Vue 3 Project Using npm and Vite

Vue 3, the latest iteration of the popular JavaScript framework, has garnered attention for its enhanced reactivity system and the Composition API. When combined with Vite, a build tool that prioritizes speed and efficiency, Vue 3 becomes an even more compelling choice for modern web development. In this blog post, we will provide a comprehensive guide to setting up a Vue 3 project using npm and Vite, empowering developers to kickstart their Vue 3 journey with confidence.

(2) Prerequisites

Before diving into the project setup, ensure that Node.js and npm are installed on your system. These tools are essential for managing dependencies and running scripts within your Vue 3 project. Once you have Node.js and npm installed, you are ready to embark on the journey of setting up your Vue 3 project.

Step 1: Creating a New Vue 3 Project

To create a new Vue 3 project, open your code editor (I use VS Code) then open the built-in terminal and run the following command:

npm init vite

Choose project name then choose vue as a framework then Javascript as a variant.
This command initializes a new Vue 3 project using Vite as the build tool, setting up the necessary project structure and dependencies.

Step 2: Navigating to the Project Directory

Once the project has been created, navigate to the project directory using the following command:

cd <project name>

This command will take you to the root directory of your newly created Vue 3 project.

Step 3: Installing Dependencies

Next, install the project dependencies using npm. Run the following command in your terminal:

npm install

This command will fetch and install all the required dependencies specified in the project's package.json file.

Step 4: Running the Development Server

To start the development server and begin working on your Vue 3 project, run the following command:

npm run dev

This command initiates the Vite development server, providing a fast and efficient development environment for your Vue 3 application.

Step 5: Building for Production

When you are ready to build your Vue 3 project for production, run the following command:

npm run build

This command triggers the production build process, generating optimized bundles for deployment.

Step 6: Launching the Production Server

To preview the production build locally, run the following command:

npm run serve

This command serves the production build of your Vue 3 project, allowing you to preview the optimized application locally before deployment.

Exploring the project structure and key files

Vue 3, renowned for its reactivity system and the Composition API, offers a well-defined project structure that facilitates organized and scalable development. In this section, we will explore the Vue 3 project structure and delve into the key files that form the foundation of a Vue 3 application, empowering developers to gain a comprehensive understanding of their Vue 3 projects.

Project Structure Overview

Upon creating a new Vue 3 project, developers are presented with a well-organized directory structure that fosters clarity, maintainability, and scalability. Let's take a closer look at the key directories and files within a typical Vue 3 project:

The src Directory

The src directory serves as the heart of a Vue 3 project, housing the source code and essential files that constitute the application.
Within the src directory, developers will encounter the following key files and subdirectories:

• main.js: This file acts as the entry point of the Vue 3 application, where the Vue instance is created and the root component is mounted to the DOM. It serves as a pivotal file in the project structure, orchestrating the initialization of the Vue 3 application.
• App.vue: As the root component of the application, App.vue encapsulates the overarching layout and structure of the user interface. It typically consists of the template, script, and style sections, embodying the essence of the application's visual and interactive components.
• components Directory: The components directory houses reusable and modular Vue components that contribute to the building blocks of the application. Organizing components in this dedicated directory promotes code reusability, maintainability, and a structured approach to component-based development.
• assets Directory: Within the assets directory, developers can store static assets such as images, fonts, and stylesheets that are utilized across the application. This directory ensures a cohesive and organized approach to managing project assets.
• views Directory: The views directory contains Vue components that represent distinct pages or views within the application. By organizing views separately, developers can maintain a clear separation of concerns and facilitate streamlined navigation within the project.
• router Directory (if using Vue Router): When incorporating Vue Router for client-side routing, the router directory hosts the routing configuration and related files, enabling developers to define and manage the application's navigation logic in a centralized manner.
• store Directory (if using Vuex/pinia): If Vuex/pinia is employed for state management, the store directory accommodates the state management logic, including modules, actions, mutations, and getters, that collectively govern the application's global state.

Additional Configuration Files

In addition to the src directory, Vue 3 projects typically encompass various configuration files that influence the behavior and settings of the application.
Notable configuration files include:

• package.json: The package.json file contains metadata about the project, as well as the dependencies, scripts, and configuration settings essential for managing the project's development, dependencies, and build processes.
• vite.config.js: When utilizing Vite as the build tool, the vite.config.js file houses the configuration for the Vite build system, allowing developers to customize the project's build process, asset handling, and development server settings.
• Additional Configuration Files: Depending on the specific requirements of the project, developers may encounter additional configuration files such as .eslintrc, babel.config.js, or .editorconfig that contribute to the overall project configuration and development workflow.

Conclusion

By following these steps, you have successfully set up a Vue 3 project using npm and Vite. With a robust development environment and efficient build process at your disposal, you are well-equipped to embark on your Vue 3 development journey with confidence, leveraging the enhanced reactivity system and the innovative Composition API offered by Vue 3. The Vue 3 project structure and key files provide a robust foundation for building modern and responsive web applications. By gaining a comprehensive understanding of the project structure and the purpose of key files, developers can streamline development, promote code maintainability, and leverage the full potential of Vue 3's capabilities.
