Vue DNI Validator

This library is a collection of utilities that allows you to check if a DNI is valid or not and to transform a string to the expected format.

Supported DNIs:

• Chilean (RUT)

Installation

npm install vue-dni --save
# or
yarn add vue-dni

import { rutValidator, rutFilter, rutInputDirective } from 'vue-dni';

Usage

This library has three base features: a validator, a filter and a directive.

Validator

The validator checks the passed string and returns a boolean depending on the string's validity as a RUT. We have tested it with vue-validator and the following example uses that library but it should be usable by any library that uses booleans for validation (like vee-validate).

import Vue from 'vue';
import { rutValidator } from 'vue-dni';

Vue.validator('rutValidator', rutValidator);

And then in your template you can use an <input> to bind the validator

<input type="text" name="user[rut]" v-validate:rut="['rutValidator']">

You can bind this validator to show an error message too

<div class="error" v-if="!$validator.rut.pristine && $validator.rut.rutValidator">This RUT is not valid</div>

Filter

With the RUT filter you can format any string to appear as a RUT.

import Vue from 'vue';
import { rutFilter } from 'vue-dni';

Vue.filter('rutFilter', rutFilter);

and then do the render and filtering

{{ user.rut }}
<!--  123124124 -->

{{ user.rut | rutFilter }}
<!--  12.312.412-4 -->

Directive

If you want to format the user input in a text field use the included directive. By default it'll format the string on blur but it can be configured to format while the text is being written.

import Vue from 'vue';
import { rutInputDirective } from 'vue-dni';

Vue.directive('rut', rutInputDirective);

And then in your template you can use it like this

<!-- Format on blur -->
<input type="text" name="user[rut]" v-dni>

<!-- Format live (while text is being written) -->
<input type="text" name="user[rut]" v-dni:live>
