Vue.js: Organizing Your Project Structure and Best Practices
Introduction
In this article, we’ll explore the capabilities of Vue.js, a popular open-source JavaScript front-end development framework. Vue.js allows developers to create single-page applications and provides a lightweight, minimalist framework design, which gives it an advantage over other frameworks such as Angular and React. We’ll also discuss best practices and tips for organizing your Vue.js project structure for productivity and maintainability.
Standardizing the File Structure
The file structure of a Vue.js project plays a crucial role in maintaining code organization and readability. In addition to the default file structure provided by Vue CLI, we recommend standardizing the following directories for increased predictability:
Guides
The Guides directory is the central location for all project-related documentation. By including a README.md file at the root of each directory, you state the goals of that directory and guidelines for its contents. This ensures that project items are documented and easily accessible within the IDE.
Helpers
The helper directory is common in many Vue.js projects and contains basic input and output functions that can be reused throughout the project. These functions are easy to test in unit tests and can be imported and used when needed. By starting with a single index.js file and breaking it down into more specific files such as https.js, cache.js, and time.js, you can keep your code organized and remove unused functionality from your production bundles.
Layouts
Layout catalogs are used to define layout components that can be reused on multiple pages. These components define the overall structure of the page, such as B. Number of columns, presence of sidebars, and inclusion of headers and footers. Although layout components are often few in number, they provide a convenient abstraction for consistent page layout.
Mixins
The mixins directory is where you can organize all your Vue.js mixins. To make searching easier, it’s a good idea to add the word “mixin” to the end of each filename. While mixins were commonly used in Vue 2 projects, Vue 3 introduces the Composition API, which may lead to composable directories being introduced instead of mixins.
Plugins
The Plugins directory is used to install and configure third-party Vue libraries and packages. Although it’s called a “plugin”, it can include more than just third-party libraries registered via Vue’s .use() method. It is recommended to create an index.js file for simpler setups and separate files for more complex setups. Separating the installation and setup of third-party plugins can make your codebase more organized and maintainable.The Plugins directory is used to install and configure third-party Vue libraries and packages.

Globals
The globals.js file is used to register global variables and functions for your Vue application. Although global variables should be used sparingly, it is helpful to have a central location to store them. By adding them to a Vue prototype or widget, you can ensure they are accessible throughout your application.
Best Practices for Vue Components
When working with Vue components, it is important to follow best practices to maintain code quality and readability. Here are some tips to consider:
Component Naming
When creating a component in Vue.js, consider using PascalCase or kebab-case. PascalCase is recommended for single-file components and strings in data types, while kebab-case is suitable for kebab-case. This convention helps differentiate between components and HTML elements and allows for better autocompletion.
Custom Event Emitting
When emitting custom events, it is best to use kebab-case to maintain consistency and readability. This is because listeners in the parent component use the same syntax to listen to the event.
Data Declaration
When using the Options API to declare component data, it is important to always return a function instead of a plain object. Returning a function ensures that each component instance has its own unique data object, promoting reusability.
Shorthand Directives
Vue provides shorthand directives for commonly used directives like v-bind and v-on. While it is great to use these shorthands, it is important to establish a convention across your project. You should either always use them or never use them to maintain cohesiveness and readability.
Avoid Direct DOM Access
To maintain the integrity of the Vue application, it is recommended to avoid direct DOM access whenever possible. Instead, use the $refs property to access the DOM. This approach is more maintainable and eliminates the need to rely on specific class names.
Code Organization
To improve code reusability and maintainability, consider keeping shared or static functions/properties in a separate file. This helps keep the code organized and ensures that reusable code is easily accessible.
Regularly Update NPM Packages
To avoid dependency errors and take advantage of the latest features and bug fixes, it is important to regularly update NPM packages. This includes packages like Vuetify, which regularly releases updates and may introduce breaking changes. By staying up-to-date, you can avoid issues and benefit from the improved functionality provided by individual packages.
Conclusion
Vue.js is a powerful front-end development framework for creating single-page applications. By following best practices and organizing your project structure, you can improve code maintainability and productivity. Additionally, adhering to conventions for component naming, emitting events, and using shorthand directives can enhance code readability and cohesion. Regularly updating NPM packages ensures that you have access to the latest features and bug fixes. By implementing these practices, you can create high-quality Vue.js applications that are scalable and maintainable.
