# Vue Formulate
|
|
---------------
|
|
|
|
### What is it?
|
|
|
|
Vue Formulate is a [Vue](https://vuejs.org/) plugin that exposes an elegant
|
|
mechanism for building and validating forms with a centralized data store.
|
|
|
|
### Installation
|
|
|
|
First download the `vue-formulate` package from npm:
|
|
|
|
```sh
|
|
npm install vue-formulate
|
|
```
|
|
|
|
Install `vue-formulate` like any other vue plugin:
|
|
|
|
```js
|
|
import Vue from 'vue'
|
|
import formulate from 'vue-formulate
|
|
|
|
Vue.use(formulate)
|
|
```
|
|
Finally `vue-formulate` needs to access your vuex store. You can choose to.
|
|
|
|
### Usage
|
|
|
|
`vue-formulate` automatically registers two components `formulate` and
|
|
`formulate-element`. These two elements are able to address most of your form
|
|
building needs. Here's a simple example:
|
|
|
|
```html
|
|
<template>
|
|
<formulate name="registration">
|
|
<formulate-element
|
|
name="name"
|
|
type="text"
|
|
label="What is your name?"
|
|
validation="required"
|
|
/>
|
|
<formulate-element
|
|
name="email"
|
|
type="email"
|
|
label="What is your email address?"
|
|
validation="required(Email address)|email"
|
|
/>
|
|
<formulate-element
|
|
type="submit"
|
|
name="Register"
|
|
/>
|
|
</formulate>
|
|
</template>
|
|
```
|
|
|
|
### Validation Rules
|
|
|
|
There are several built in validation methods and you are easily able to add
|
|
your own.
|
|
|
|
Rule | Arguments
|
|
----------|---------------
|
|
required | label
|
|
email | label
|
|
confirmed | label, confirmation field
|
|
|
|
You can add as many validation rules as you want to each `formulate-element`,
|
|
simply chain your rules with pipes `|'.
|
|
|
|
```
|
|
validation="required(My Label)|confirmed(Password Field, confirmation_field)"
|
|
```
|
|
|
|
Adding your own validation rules is simple, simply pass an additional object
|
|
of rules in your installation:
|
|
|
|
```js
|
|
Vue.use(formulate, {
|
|
rules: {
|
|
isPizza: ({field, value, error, values}, label) => value === 'pizza' ? false : `${label || field} is not pizza.`
|
|
}
|
|
})
|
|
```
|
|
|
|
Validation rules expect a return of `false` if there are no errors, or a error
|
|
message string. Validation rules are all passed an object with the `field` name,
|
|
`value` of the field, `error` function to generate an error message, and all the
|
|
`values` of the entire form.
