Is there any way to remove extra white space in JSX classname strings?

There are a few ways to remove extra white space in JSX classname strings.

You can use a linter like ESLint with the no-multi-spaces rule. This rule will flag any classname strings that contain multiple spaces between words. You can also use a formatter like Prettier with the --print-width option. This option will trim any whitespace that exceeds the specified width.

If you are using a build tool like Webpack, you can use a plugin like mini-css-extract-plugin with the clean-css option. This option will minify your CSS and remove any unnecessary whitespace.

You can also use a post-processing tool like PostCSS with the postcss-clean plugin. This plugin will remove any unnecessary whitespace from your CSS.

Here are some examples:

// Before
const className = 'foo bar baz';

// After
const className = 'foo-bar-baz';

Here is an example of how to use ESLint with the no-multi-spaces rule:

// .eslintrlc.js
module.exports = {
  rules: {
    'no-multi-spaces': ['error'],
  },
};

Here is an example of how to use Prettier with the --print-width option:

npx prettier --print-width 80

I hope this helps!
