Tips to Write Cleaner Vue.js Code

When transitioning from one project to another (for example when changing jobs) there is always this period of time when I need to adjust to the new project flow and development process.

There are things that are unique for certain projects but in Vue, there are things that are considered good practices for building clean and maintainable Vue based projects.

In this article, I would like to list these best practices so that you can start using them in your Vue projects :)

? 10 Tips to Write Cleaner Vue.js Code

Clean and maintainable code is the backbone of any successful application. Vue.js, with its intuitive API, makes it easy to write clean code, but there’s always room for improvement. Here are 10 actionable tips to help you write cleaner Vue.js code.

1. Use the Composition API Wisely

Break large logic into smaller, reusable composables to maintain modularity and readability.

Example: Instead of cramming all logic into a setup() function, create custom hooks for distinct functionalities.

2. Follow Vue’s Naming Conventions

Use PascalCase for component file names and kebab-case for template usage.

Example: Name your component UserProfile.vue and use it as in templates.

3. Avoid Overusing Vuex or Pinia

Keep transient UI states (e.g., modal visibility) local to the component rather than in global state management.

Example: Use ref or reactive for temporary states.

4. Utilize Slots Effectively

Use named slots for better flexibility in reusable components and document their usage.

Example: Create a Card component with for customizable headers.

5. Leverage Scoped Styles

Use scoped styles in

Example: Apply component-specific styles without affecting other parts of the application.

6. Write Reusable Components

Break down UI elements into reusable, focused components, avoiding overly generic designs.

Example: Instead of hardcoding a button, create a configurable Button component that supports props for different styles.

7. Handle Asynchronous Code Gracefully

Use async/await for API calls and handle errors using a central utility function.

Example: Create a useApi composable to encapsulate API logic and error handling.

8. Document Props and Emit Events

Clearly define and document props and events using props and emit annotations or TypeScript.

Example: Use defineProps and defineEmits in Vue 3 for clarity and type safety.

9. Lint Your Code

Set up ESLint and Prettier with Vue-specific configurations to enforce code quality and consistency.

Example: Integrate linting into your CI/CD pipeline to automate code reviews.

10. Keep Templates Simple

Avoid placing complex logic in templates; instead, use computed properties or methods.

Example: Replace v-if="list.filter(item => item.active).length > 0" with a computed property activeItems.
