Vue Input Facade

A lightweight and dependency free input masking library created specific for Vue

Build Status Coverage Status License code style: prettier


npm i vue-input-facade
yarn add vue-input-facade



Installs the component, directive and filter for your entire application.

import InputFacade from 'vue-input-facade'


Install per component as needed

import { InputFacade, facade, filter } from 'vue-input-facade'

export default {
  components: { InputFacade },
  directives: { facade },
  filters: { facade: filter },
  // ... rest of component config

Default Mask Tokens

  • S = alpha characters
  • # = numerical characters
  • X = alpha numerical characters
  • A = alpha characters, transformed to uppercase
  • a = alpha characters, transformed to lowercase
  • \ = escape any of the above characters
  • ? = mark the preceding character as optional [0 or 1]
  • * = mark the preceding character as optional & repeating [0 or more]
  • | = used for alternative static characters: A|B|C will accept A or B or C

See the token source file for definition signature

Note about special input types

The masking library does not currently work on special input types such as number, email etc. This is due to browsers treating these special inputs differently than text input and not supporting the same API. As such, only use vue-input-facade with <input type="text|tel|search">.


As Component

<label>Phone Number</label>
<input-facade mask="(###) ###-####" name="phoneNumber" type="tel" />

As Directive

<input type="text" v-facade="'##/##/##'" />

Migrating existing projects

If you are migrating an existing project to vue-input-facade from another plugin and dont want to touch the whole codebase. You may pass options during plugin installation to override the default tokens or directive name.

import InputFacade from 'vue-input-facade'

// migrating from v-mask
const options = {
  // rename the directive from: v-facade to: v-mask
  name: 'mask',

  // use these tokens instead of the default
  tokens: {
    '#': { pattern: /\d/ },
    'A': { pattern: /[a-z]/i },
    'N': { pattern: /[0-9a-z]/i },
    'X': { pattern: /./ }

Vue.use(InputFacade, options)
