Configuration

Config

You may need to configure some options to tweak some of the plugin internals. This is not required, but could cause conflicts. For example, using a property called errors on your vue instance may cause conflicts. Here is how you would set up the options, along with the default values:

import Vue from 'vue';
import VeeValidate from 'vee-validate';

const config = {
  aria: true,
  classNames: {},
  classes: false,
  delay: 0,
  dictionary: null,
  errorBagName: 'errors', // change if property conflicts
  events: 'input|blur',
  fieldsBagName: 'fields',
  i18n: null, // the vue-i18n plugin instance
  i18nRootKey: 'validations', // the nested key under which the validation messages will be located
  inject: true,
  locale: 'en',
  validity: false,
  useConstraintAttrs: true
};

Vue.use(VeeValidate, config);
Property Type Default Description
aria boolean true Allows setting aria-invalid and aria-required attributes on HTML inputs.
classNames object The classes to be applied depending on the state of the input.
classes boolean false Applies automatic classes on HTML inputs being validated.
delay number 0 The default debounce time for all inputs (only affects validations).
dictionary object|null null A dictionary to be merged with the internal dictionary. (Check the Error Messages and Localization sections.)
errorBagName string 'errors' The name of the ErrorBag object that will be injected in each of Vue's instances' data. Used to avoid conflicts with other plugins.
events string 'input' Pipe separated list of the default event names that will be listened to, to trigger validation. If an empty string is provided, it will disable all listeners.
fieldsBagName string 'fields' The name of the Fields (flags) object that will be injected in each of Vue's instances' data.
fastExit boolean true Whether the validation should stop after the first failure for each field, you can opt in or out from either settings by using the continues and the bails modifiers.
i18n VueI18n | null null The vue-i18n instance, if provided will integrate vee-validate with the i18n plugin and will use it to produce the error messages instead of the built in dictionary. More about that here.
i18nRootKey string 'validations' The key name of the validation messages for each locale.
inject boolean true Specifies if a validator instance should be injected automatically for all components. (See Component Injections for more information.)
locale string 'en' The default language for the validation messages.
validity boolean false Set custom validity Constraint validation on native HTML inputs.
useConstraintAttrs boolean true Enables rule inference on native HTML inputs.

Installation

Vue Plugin API

You can install vee-validate using Vue's plugin API.

import Vue from 'vue';
import VeeValidate from 'vee-validate';

Vue.use(VeeValidate, config);

Manual Installation

You might be interested in using VeeValidate exposed components as you see fit without having to install the plugin, you can do this by creating an instance of the VeeValidate plugin.

import Vue from 'vue';
import VeeValidate from 'vee-validate';

const vee = new VeeValidate(config, Vue);

Using this method will not add any directives, mixins, or components to your app, instead it passes everything vee-validate needs to set itself up and you will be responsible for using the plugin manually which is helpful if you are only planning to use standalone features like the Validator.verify API.

Runtime Configuration

You also could modify the plugin config after installation by importing the default module and using the configure method:

import VeeValidate from 'vee-validate';

VeeValidate.configure({
  // config properties
});
