Currency "zł" after amount

[mateusz-wyka]

I'm trying to modify code example from demo "Money format: full via hooks". I'm working on Nuxt 3.

Here is my code

const tokens = {
  0: {
    pattern: /[0-9]/,
    multiple: true,
  },
  9: {
    pattern: /[0-9]/,
    optional: true,
  },
};

const amountMask = reactive({
  mask: '0.99',
  tokens,
  preProcess: (value: string) => value.replace(/[$,]/g, ''),
  postProcess: (value: string) => {
    if (!value) return '';

    const sub =
      3 - (value.includes('.') ? value.length - value.indexOf('.') : 0);

    return Intl.NumberFormat('pl', {
      style: 'currency',
      currency: 'PLN',
    })
      .format(Number(value))
      .slice(0, sub ? -sub : undefined);
  },
});

<input v-maska:[options]>

I would like to:

1. The tokens to be in a variable. I'm not sure how to properly modify data-maska-tokens="0:\d:multiple|9:\d:optional" to object.
2. The currency was at the end of the amount for e.g. 5499,99 zł

I tried many combinations, and the amount in the input went crazy.

Can someone help me?
Thanks
