How to use mask in vuetify text-field?

In Vuetify 2 masks have been removed

You can use return-masked-value prop

<v-text-field
    :value="currentValue" 
    return-masked-value
    mask="###.###.###-##"
    @input="handleInput"
></v-text-field>

Note that currently in v0.17 there is a bug with returning unmasked initial value.

With Vuetify 2 they removed the mask attribute. However, there is a third-party solution. You can use the lightweight package v-mask by probil:

Install the v-mask package (unpacked size 71.7 kB)

npm install v-mask

In your main.js import the package and add it as a directive:

import { VueMaskDirective } from 'v-mask'
Vue.directive('mask', VueMaskDirective);

Then in your component add the mask using v-mask:

<v-text-field
  v-mask="'###.###.###-##'"
  :value="currentValue" 
  @input="handleInput"
/>
