A guide on incorporating dynamic TailwindCSS classes into React component elements

Just beginning to explore TailWindCSS, I am interested in adding conditional styling to a Button element for enabling/disabling it. Is there a way that I can apply specific styles/classes (such as "opacity-50 cursor-not-allowed") to the button based on certain conditions?

    <button
          className="bg-blue-500 hover:bg-blue-400 text-white font-bold py-2 px-4 border-b-4 border-blue-700 hover:border-blue-500 rounded mr-3"
          disabled={!globalContext.users.length > 0}
          onClick={handleClearResultsClick}
        >
          Clear Results
    </button>

One option is to utilize the latest ES6 template literals.
Here's a basic React component that disables the (-) button when the counter reaches 0.

The CSS class .pointer-even-none from tailwindCSS is responsible for styling the disabled button.

const [count, setCount] = useState(0);

return (
  <Fragment>
       {/* Substract button with tailwind styles */}
      <button className={`p-2 ${count <= 0 ? 'opacity-50 pointer-events-none': 'bg-red-700'}`} 
              onClick={() => setCount(count - 1)}>
              Subtract
      </button>

      {/* Counter display */}
      <span className="p-2">{count}</span>

      {/* Add button with tailwind styles */}
      <button className="p-2 bg-green-700"
              onClick={() => setCount(count + 1)}>
              Add
      </button>
  </Fragment>
)

combineClassNames('foo', 'bar'); // => 'foo bar'
combineClassNames('foo', { bar: true }); // => 'foo bar'
combineClassNames({ 'foo-bar': true }); // => 'foo-bar'
combineClassNames({ 'foo-bar': false }); // => ''
combineClassNames({ foo: true }, { bar: true }); // => 'foo bar'
combineClassNames({ foo: true, bar: true }); // => 'foo bar'

// combining lots of arguments with various types
combineClassNames('foo', { bar: true, duck: false }, 'baz', { quux: true }); // => 'foo bar baz quux'

// other falsy values are simply ignored
combineClassNames(null, false, 'bar', undefined, 0, 1, { baz: null }, ''); // => 'bar 1'

You can utilize this lightweight module called "classname"

https://www.npmjs.com/package/classnames

This will help organize your code nicely
