12 minutes read

To use Sass extend in Vue 3 with Vite, you can include the necessary styles in a separate SCSS file and then import that file into your Vue component. To do this, install the necessary dependencies such as sass and sass-loader in your project. Then, create a new SCSS file and define the styles you want to extend.


In your Vue component, import the SCSS file using the standard import syntax. You can then use the @extend directive in your component's style section to apply the styles defined in the imported SCSS file.


By using Sass extend in Vue 3 with Vite, you can efficiently reuse styles across different components without repeating code, leading to a more maintainable and cleaner codebase.

What are the best practices for organizing Sass extend files in Vue 3 Vite?

  1. Create a separate Sass file for each component or page: It is a good practice to organize your Sass extend files by creating a separate file for each component or page in your Vue project. This will help keep your code organized and make it easier to maintain and update.
  2. Use a consistent naming convention: Use a consistent naming convention for your Sass extend files to make it easier to identify and locate them in your project. You can use a naming convention based on the component or page name, such as _component-name.scss or _page-name.scss.
  3. Use folders to group related Sass extend files: If you have a large number of Sass extend files in your project, consider organizing them into folders based on functionality or feature. This will help you keep your codebase tidy and make it easier to navigate.
  4. Import Sass extend files in the main stylesheet: Once you have organized your Sass extend files, import them in the main stylesheet of your Vue project. This will ensure that the styles are applied correctly to the respective components or pages.
  5. Use variables and mixins: Use Sass variables and mixins to centralize common styles and functionalities that are used across multiple components or pages in your project. This will help you maintain consistency and make it easier to update styles across your project.
  6. Keep your Sass extend files modular: Keep your Sass extend files modular by breaking down styles into smaller, reusable components. This will make it easier to maintain and update your styles and improve the overall performance of your project.
  7. Document your Sass extend files: Document your Sass extend files by adding comments and annotations to clarify their purpose and usage. This will help you and other developers understand the codebase better and make it easier to collaborate on the project.
