Prettier single quote for JavaScript and JSON, double quote for HTML, Sass and CSS

Question

In VSCode, whenever I save a file, Prettier changes all single quotes to double quotes. I want to keep this behaviour for SCSS and CSS files, but want to change it for JavaScript and JSON files.

I am aware of the setting "prettier.singleQuote": true, but this will change double quotes to single quotes in all file types.

How can I activate single quote only for JavaScript and JSON files and keep double quote for SCSS and CSS files?

Answer 1

Use a Prettier configuration file in your project folder: .prettierrc

Inside your config file use Prettier overrides: https://prettier.io/docs/en/configuration.html#configuration-overrides

So in your case this example config should work (.prettierrc):

{
    "singleQuote": true,
    "overrides": [
        {
            "files": ["**/*.css", "**/*.scss", "**/*.html"],
            "options": {
                "singleQuote": false
            }
        }
    ]
}
