10 Vue 3 Project Structure Best Practices

Vue 3 is the latest version of the popular JavaScript framework, and it comes with a lot of new features and improvements. With the new version, it’s important to understand the best practices for structuring your Vue 3 projects.

In this article, we’ll discuss 10 best practices for structuring your Vue 3 projects. We’ll look at how to organize your components, how to structure your code, and how to use the new features of Vue 3 to your advantage. By following these best practices, you’ll be able to create more efficient and maintainable projects.

1. Use a single-file component

A single-file component allows you to keep all of your code related to a particular feature in one place. This makes it easier to find and maintain the code, as well as making it more organized and efficient. It also helps with readability since everything is contained within one file.

Additionally, using a single-file component can help speed up development time by allowing you to quickly make changes without having to search through multiple files. Finally, it’s a great way to ensure that all of your components are consistent and adhere to best practices.

2. Create components for each page

By creating components for each page, you can easily reuse code and keep your project organized. This makes it easier to maintain the codebase and debug any issues that may arise.

Creating components also allows you to break down complex pages into smaller, more manageable pieces. This helps make development faster and more efficient. Additionally, by breaking down a page into components, you can create reusable elements that can be used across multiple pages. This will save time when developing new features or making changes to existing ones.

3. Organize your assets

When you have a large project, it can be difficult to keep track of all the different components and files. By organizing your assets into folders, you make it easier for yourself and other developers to find what they need quickly and easily.

For example, you could create separate folders for components, views, services, styles, images, etc. This way, when someone needs to find something, they know exactly where to look. Additionally, this helps with code readability and maintainability since everything is organized in an intuitive manner.

4. Keep the state in Vuex

Vuex is a state management library that allows you to store and manage the application’s data in one centralized location. This makes it easier for developers to keep track of changes, debug issues, and ensure that all components are using the same data.

Vuex also provides features such as time-travel debugging, which allows developers to go back in time and see how the application was behaving at any given point. Additionally, Vuex can be used to create global event bus systems, allowing components to communicate with each other without having to pass props down multiple levels.

5. Prefer functional components over class-based ones

Functional components are simpler and easier to read, making them more maintainable. They also have better performance since they don’t need to be instantiated like class-based components do. Finally, functional components can take advantage of the new Composition API in Vue 3, which allows for greater flexibility when it comes to code organization.

6. Avoid using global stylesheets

Global stylesheets can cause conflicts between components, making it difficult to debug and maintain.

Instead of using global stylesheets, use scoped stylesheets for each component. This way, you can ensure that the styling is specific to the component and won’t interfere with other components. Additionally, this makes it easier to make changes to individual components without affecting the entire project.

7. Don’t use inline styling

Inline styling makes it difficult to maintain and update your code. It also makes it hard for other developers to understand what you’ve done, as they won’t be able to see the styles in one place.

Instead of using inline styling, use a CSS preprocessor like Sass or Less. This will allow you to keep all of your styles in one file, making them easier to manage and update. You can also use variables and mixins to make your code more organized and efficient.

8. Separate CSS and JavaScript files

CSS and JavaScript files are two different types of code, and they should be kept separate for a few reasons. Firstly, it makes the code easier to read and maintain. Secondly, it helps keep your project organized and prevents conflicts between CSS and JavaScript code. Finally, it allows you to use pre-processors like Sass or Less to make writing and managing your CSS much easier.

By separating your CSS and JavaScript files, you can ensure that your Vue 3 project structure is well-organized and easy to manage.

9. Put all of your code into separate modules

By separating your code into modules, you can easily manage and maintain the different components of your project. This makes it easier to debug any issues that may arise, as well as make changes or add new features without having to worry about breaking existing functionality.

Additionally, by keeping all of your code in separate modules, you can ensure that each module is responsible for a single purpose. This helps keep your code organized and easy to read, which will save time when making changes or debugging issues. Finally, this also allows you to reuse code across multiple projects, saving you time and effort.

10. Use ESLint to keep your code clean

ESLint is a tool that helps you identify and fix problems with your code. It can detect errors, potential problems, and style issues in your code. This makes it easier to maintain the quality of your codebase over time.

Using ESLint also ensures that all developers on the project are following the same coding standards. This makes it easier for everyone to read and understand each other’s code, which leads to fewer bugs and faster development cycles.

Finally, using ESLint will help you catch any mistakes before they become bigger problems. By catching them early, you can save yourself time and effort in the long run.
