Vue CLI sourcemaps to style part of vue component file

Sourcemaps are an essential tool for debugging and understanding the source code of a web application, especially when it comes to CSS and stylesheets. They provide a mapping between the compiled code (e.g., minified or transpiled code) and the original source code, making it easier to locate and debug issues.

When working with Vue.js and the Vue CLI, you can enable sourcemaps for your stylesheets to have better visibility into your CSS code. By default, Vue CLI generates sourcemaps for JavaScript files, but it requires some additional configuration to enable sourcemaps for the style part of Vue component files.

To enable sourcemaps for the style part of Vue component files, you can follow these steps:

1. Open your Vue CLI project in a code editor.

2. Locate the vue.config.js file in the root directory of your project. If the file doesn't exist, create it.

3. Add the following code to the vue.config.js file:

module.exports = {
  css: {
    sourceMap: true
  }
}

This configuration tells Vue CLI to generate sourcemaps for CSS files, including the style part of Vue component files.

4. Save the vue.config.js file.

5. Restart your development server to apply the changes.

Once you have enabled sourcemaps for the style part of Vue component files, you can use your browser's developer tools to inspect and debug the styles. When you inspect an element, the styles associated with that element will be shown with references to the original source code, making it easier to identify and modify the styles.

Keep in mind that enabling sourcemaps for styles may have an impact on the build performance and file size of your application. It's recommended to enable sourcemaps only during development and disable them in production builds to optimize performance.

In conclusion, sourcemaps are a powerful tool for debugging and understanding your Vue.js application's styles. By enabling sourcemaps for the style part of Vue component files in Vue CLI, you can gain better visibility into your CSS code and simplify the debugging process.
