Vue-the-mask is a lightweight and flexible input mask library for Vue.js applications. It provides an easy way to format and validate user input for various types of data, such as phone numbers, dates, and credit card numbers, enhancing the user experience and data integrity in forms.

Pros

• Simple integration with Vue.js components
• Lightweight and performant
• Customizable mask patterns
• Supports both Vue 2 and Vue 3

Cons

• Limited built-in mask patterns (requires custom patterns for complex scenarios)
• May not handle all international input formats out of the box
• Documentation could be more comprehensive
• Lacks advanced features like dynamic masking

Code Examples

1. Basic usage with a phone number mask:

<template>
  <the-mask
    v-model="phoneNumber"
    mask="(###) ###-####"
    placeholder="Enter phone number"
  />
</template>

<script>
import { TheMask } from 'vue-the-mask'

export default {
  components: { TheMask },
  data() {
    return {
      phoneNumber: ''
    }
  }
}
</script>

2. Custom mask for a date input:

<template>
  <the-mask
    v-model="date"
    mask="##/##/####"
    placeholder="DD/MM/YYYY"
  />
</template>

<script>
import { TheMask } from 'vue-the-mask'

export default {
  components: { TheMask },
  data() {
    return {
      date: ''
    }
  }
}
</script>

3. Using tokens for more complex masks:

<template>
  <the-mask
    v-model="customInput"
    :mask="['(##) ####-####', '(##) #####-####']"
    :tokens="customTokens"
    placeholder="Enter custom input"
  />
</template>

<script>
import { TheMask } from 'vue-the-mask'

export default {
  components: { TheMask },
  data() {
    return {
      customInput: '',
      customTokens: {
        '#': { pattern: /\d/ },
        'X': { pattern: /[0-9a-zA-Z]/ }
      }
    }
  }
}
</script>

Getting Started

1. Install the package:

   npm install vue-the-mask
   

2. Import and use in your Vue component:

   <template>
     <the-mask v-model="value" mask="##.##.##" />
   </template>
   
   <script>
   import { TheMask } from 'vue-the-mask'
   
   export default {
     components: { TheMask },
     data() {
       return {
         value: ''
       }
     }
   }
   </script>
   

3. For global registration (in your main.js or similar):

   import Vue from 'vue'
   import VueTheMask from 'vue-the-mask'
   
   Vue.use(VueTheMask)
