vue-mask-next is a simple input mask library for Vue.js 3, designed to facilitate the creation of input masks for fields in your Vue.js 3 applications. This library is inspired by vue-3-mask but provides additional functionality such as prefilled value support, and it currently works with Vue version 3.4.26+, composition API, and script setup.

Installation

Install the library via npm or yarn:

npm install vue-mask-next

or

yarn add vue-mask-next

Usage

Global Registration

In your Vue 3 application, open the main.js (or main.ts) file and import the MaskInput component from the vue-mask-next library. Register it globally:

import { createApp } from "vue";
import App from "./App.vue";
import { MaskInput } from "vue-mask-next";

const app = createApp(App);

app.component("MaskInput", MaskInput);

app.mount("#app");

Now you can use the MaskInput component throughout your application.

Local Registration

If you prefer to register the component locally, you can do so in the components section of your Vue component:

import { MaskInput } from "vue-mask-next";

export default {
  components: {
    MaskInput,
  },
};

Using MaskInput in Your Components

To use the MaskInput component in your Vue components, simply include it in your template and provide a mask prop with the desired pattern. Various mask patterns are supported:

  • #: Any digit (0-9)
  • X: Any alphanumeric character (0-9, a-z, A-Z)
  • S: Any alphabetic character (a-z, A-Z)
  • A: Any uppercase alphabetic character (A-Z)
  • a: Any lowercase alphabetic character (a-z)
  • !: Escape character (use the next character in the mask as a literal)

Here's an example of using the MaskInput component with a phone number mask:

<template>
  <div>
    <h1>Phone number input example</h1>
    <MaskInput v-model="phoneNumber" mask="(##) ####-####" />
  </div>
</template>

<script>
export default {
  data() {
    return {
      phoneNumber: "",
    };
  },
};
</script>

In this example, the MaskInput component will enforce the provided phone number mask as the user types, and the masked value will be stored in the phoneNumber data property.

Usage of v-bind="$attrs"

The $attrs object allows you to pass additional attributes to the underlying input element. Here are some examples:

  • Binding a placeholder:
<MaskInput
  v-model="phoneNumber"
  mask="(##) ####-####"
  placeholder="Enter phone number"
/>
  • Binding a CSS class:
<MaskInput v-model="phoneNumber" mask="(##) ####-####" class="form-control" />
  • Binding an event handler:
<MaskInput v-model="phoneNumber" mask="(##) ####-####" @focus="handleFocus" />

In each of these examples, the additional attribute is forwarded to the underlying input element using v-bind="$attrs", allowing for flexible usage and customization.

Implementation Details

The MaskInput component implementation utilizes the following:

  • A template with a single <input> element, bound to the value data property using v-model.
  • The $attrs object, which forwards any attributes passed to the component to the underlying input element using v-bind="$attrs". This allows users to apply additional attributes directly to the input element.
  • Script setup with props, including a required prop mask specifying the masking pattern.
  • Mask definitions allowing different characters to be interpreted differently in the mask pattern.
  • The applyMask function, which applies the masking logic to generate the masked value.
  • The handleInput function, triggered on input events, applies the mask to the input value, updating the value data property accordingly.
