How To Use Files With Multiple Extensions With Prettier

If you want to keep your code neat and organized while working with files that have multiple extensions, Prettier can be a handy tool in your software engineering toolkit. Prettier is a popular code formatter that can help you maintain consistent styling across your codebase. In this article, we'll walk you through how to leverage Prettier to handle files with multiple extensions effectively.

Firstly, it's essential to ensure you have Prettier installed in your project. You can easily set it up by running the following command in your terminal:

npm install --save-dev prettier

After installing Prettier, you can use it to format your code automatically. By default, Prettier supports formatting JavaScript, TypeScript, CSS, and HTML files. However, if you are dealing with files that have multiple extensions, such as `.js.erb` or `.css.scss`, you can customize Prettier to recognize and format these files correctly.

To configure Prettier to handle files with multiple extensions, you can create a `.prettierrc` file in the root of your project directory. In this configuration file, you can specify the file types you want Prettier to format.

Here's an example of a `.prettierrc` file that includes additional file extensions:

{
  "overrides": [
    {
      "files": "*.js.erb",
      "options": {
        "parser": "babel"
      }
    },
    {
      "files": "*.css.scss",
      "options": {
        "parser": "css"
      }
    }
  ]
}

In this configuration, we've defined overrides for files with extensions `.js.erb` and `.css.scss`. For `.js.erb` files, we specify the parser as "babel" to ensure proper formatting, and for `.css.scss` files, we set the parser to "css".

Once you've configured Prettier to handle files with multiple extensions, you can run Prettier to format your code, including these files. You can do this by running the following command in your terminal:

npx prettier --write .

This command tells Prettier to format all files in the current directory and its subdirectories. Prettier will apply the specified formatting rules, taking into account the custom configurations you've set up for files with multiple extensions.

By following these steps and customizing Prettier to support files with multiple extensions, you can streamline your code formatting process and ensure consistency across various file types in your project. This can ultimately help you write clean, readable code and collaborate more effectively with other developers.

So, the next time you find yourself working with files that have multiple extensions, don't fret – Prettier has got you covered!
