using a variable value on css modules class name

Question

I'm trying use use a variable in a class name with css modules in nextjs, but I'm having a bad time figuring out the right syntax.

my variable comes from the api:

const type = red

how i'm trying to do it:

<div className={` ${styles.background} ${styles.--type}`}></div>

The result that I expect:

<div className={` ${styles.background} ${styles.--red}`></div>

is there a way to do it?

Not sure what you are trying to achieve.

One solution could be to do:

const type = 'red';

<div className={`${styles.background} ${styles.type}`}></div>

However if you want to use BEM and the -- notation. You' might have to switch to brackets notation.

const type = '--red';

<div className={`${styles.background} ${styles[type]}`}></div>
