Vue 3 support

Vue 3 support is almost here with the Vuelidate 2 rewrite. Check out the next branch to see the latest progress.

Installation

 npm install vuelidate --save

You can import the library and use as a Vue plugin to enable the functionality globally on all components containing validation configuration.

 import Vue from 'vue'
import Vuelidate from 'vuelidate'
Vue.use(Vuelidate)

Alternatively it is possible to import a mixin directly to components in which it will be used.

 import { validationMixin } from 'vuelidate'

var Component = Vue.extend({
  mixins: [validationMixin],
  validations: { ... }
})

The browser-ready bundle is also provided in the package.

 <script src="vuelidate/dist/vuelidate.min.js"></script>
<!-- The builtin validators is added by adding the following line. -->
<script src="vuelidate/dist/validators.min.js"></script>
 Vue.use(window.vuelidate.default)

Basic usage

For each value you want to validate, you have to create a key inside validations options. You can specify when input becomes dirty by using appropriate event on your input box.

 import { required, minLength, between } from 'vuelidate/lib/validators'

export default {
  data () {
    return {
      name: '',
      age: 0
    }
  },
  validations: {
    name: {
      required,
      minLength: minLength(4)
    },
    age: {
      between: between(20, 30)
    }
  }
}

This will result in a validation object:

 $v: {
  name: {
    "required": false,
    "minLength": false,
    "$invalid": true,
    "$dirty": false,
    "$error": false,
    "$pending": false
  },
  age: {
    "between": false
    "$invalid": true,
    "$dirty": false,
    "$error": false,
    "$pending": false
  }
}
