Please checkout the full documentation for more detail.

Package is installable via npm.

You can also install it via bower.

bower install --save simple-vue-validator

NOTE: for bower package, please use /dist/plugin.js.

import Vue from 'vue';
import SimpleVueValidation from 'simple-vue-validator';
Vue.use(SimpleVueValidation);

Define the validators object in your vue / component instance:

validators: {
      email: function (value) {
        return Validator.value(value).required().email();
      }
    }

In the template HTML use the validation object injected by the library to display validation status / results.

<div class="message">{{ validation.firstError('email') }}</div>
