Playground Examples

Vue Example One

Show First Error For Each Field And

Only Validate Form (AKA find errors) when Form Data is submitted

<template>
    <div>        
        <input type='text' v-model='form.name' />
        <span v-if="form.errors().has('name')" v-text="form.errors().get('email')"></span>

        <input type='email' v-model='form.email' />
        <span v-if="form.errors().has('email')" v-text="form.errors().get('email')"></span>

        <input type='password' v-model='form.password' />
        <span v-if="form.errors().has('password')" v-text="form.errors().get('password')"></span>

        <input type='password' v-model='form.password_confirmation' />
        <span v-if="form.errors().has('password_confirmation')" v-text="form.errors().get('password_confirmation')"></span>

        <hr>

        <button :disabled='form.empty()' @click='submit'>
            Complete
        </button>
    </div>
</template>

import form from 'vuejs-form'

export default {
    data: () => ({
        form: form({
            email: '',
            password: '',
            password_confirmation: ''
        })
        .rules({
            email: 'email|min:5|required',
            password: 'required|min:5|confirmed'
        })
        .messages({
            'email.email': 'Email field must be an email (durr)',
            'password.confirmed': 'Whoops, :attribute value does not match :confirmed value',
        }),
   }),

    methods: {
        submit() {
            if (this.form.validate().errors().any()) return;

            console.log('submit: ', this.form.only('email', 'password'));
            console.log('submit: ', this.form.except('password_confirmation'));
        },
    }
}

Validator Api

form.rules({...})
form.messages({...})
form.validator(...)
form.validate(...)
form.hasValidator()
form.setValidator({...})

Form Register Rules

@SeeAvailableValidationRules

form(data).rules({
    name: 'required|min:4',
    link: 'required|url',
    category: 'required|within:blue,reg,green'
});

Optionally Use Arrays Syntax Instead Of Pipes

form(data).rules({
    name: ['required', 'min:4'],
    link: ['required', 'url'],
    category: ['required', 'within:blue,reg,green']
});

Form Customize Error Messages

All rules have global default error messages shown when rule fails validation.
Optionally, you are able to override the global defaults rule messages
Simply use the form(data).rules(set).messages({ '{field}.{rule}': 'custom message for failing rule on field' });

let data = { email: ['required', 'email'] }
form({ email: 'chad'}).rules({
    email: ['required', 'email']
})
.messages({
    'email.required': 'Email field is called email, needa make it an email (Hence Email Field Name, dont worry ~ we added validation just in case you forgot to make the email field an email)'
})

Form Validator Instance

Get Validator Instance

form(data).rules(options).messages(customMessages);

// form.validator().addMessage(field, error)
// form.validator().addRule(field, rules) 
// etc...

Validate Form Data

Check current form data against associated form rules
IMPORTANT: form MUST call validate() method before retrieving current errors

COMMON GOTCHA!!!!

This wont get the current form errors
The form.validate() method was Never called

let data = { name: '' };
let rules = { name: 'required' };

form(data).rules(rules).errors().list();

// --------------------------------------------
// Form SHOULD fail, but errors list is empty
// --------------------------------------------
// Output: []
// --------------------------------------------

What's the reason?

Retrieving errors before validating form data

would retrieve our error messages Api instance,
but it hasn't been filled with our forms error messages.

form.validate() compares form data against form rules, populating our form errors with failing rule messages.

Validate THEN resolve the errors (Using forms fluent api)

let data = { name: '' };
let rules = { name: 'required' };

form(data).rules(rules).validate().errors().list();
// Output: ['Name field is required']

// Again, we'll need to validate before retrieving our 
// errors to validate that the values passes our given rules
form.name = 'hello world';

form.errors().list();
// Output: ['Name field is required']

form.validate().errors().list();
// Output: [];

Fluently call validate() before calling errors() is simple and to the point.

At first, this may seem like a tedious extra step. Many may wonder why we don't simply auto-validate the data?

Reason for form.validate().errors() Instead of simply form.errors() triggering the validation.

Reactive frameworks may use errors() and the associated Error Messages Api (@See Form Error Messages Api)
Without providing the option for the end developer to determine when the form validates
Async requests, only validate once we've resolved some given data
Immediate display of errors (Not always wanted)
Option Open To Immediately show error messages (@See Vue Watcher Example)
Some other developers may only want to validate data on form submission
Many validation rules can be abstracted using the form Api to simply disable the ability to submit a button
EX: <button :disabled='form.empty()' @click='submit'> Done </button>
Then within submit() method simply run if (this.form.validate().errors().any()) return;
That allows the option to set up vuejs-form more like a traditional Form, and avoid many complexities that come along with maintaining the status of our reactive state
etc...

Form Has Validator

Determine if form has a validator instance attached to it

form.hasValidator(); // true or false

Form Set Validator

Set Validator Instance
Optionally import the validator instance itself, and extend its functionality validator().macro(add_method, method).
Then use form macros to track the current step form.macro(add_method, method).
vuejs-validators.js Also has validator life cycle hooks documented that are available here, but only documented within vuejs-form.js. Very helpful for multi-step forms

const { form, validator } = require('vuejs-form');


form().macro('setSwitchableValidators', (first, second) => {
    this.toggleValidators = 
    this.toggleBetween = first
});

`all()`

The all method returns the underlying input object represented by the form:

form({ name: 'sarah', email: 'sarah@gmail.com' }).all();

// { name: 'sarah', email: 'sarah@gmail.com' }

`boolean(property)`

The boolean method determines if the given field has a truthy or falsy values:

Truthy values: true, "true", "yes", "on", "1", 1

Falsy values: Everything else


const LoginForm = form({
    name: '',
    email: '',
    terms: ''
})

LoginForm.terms = true
LoginForm.boolean('terms') // true

LoginForm.terms = 'true'
LoginForm.boolean('terms') // true

LoginForm.terms = 'yes'
LoginForm.boolean('terms') // true

LoginForm.terms = 'on'
LoginForm.boolean('terms') // true

LoginForm.terms = "1"
LoginForm.boolean('terms') // true

LoginForm.terms = 1
LoginForm.boolean('terms') // true

`empty(one, two, three, ...)`

The empty method determines if the input property exists but the value is empty:

const ExampleForm = form({ id: '', name: 'sarah', email: 'sarah@gmail.com' });

ExampleForm.empty('name') // false
ExampleForm.empty('name', 'email') // false

ExampleForm.empty('id') // true

`except(one, two, three, ...)`

The except method grabs all of the inputs except the properties passed in:

const ExampleForm = form({ id: '', name: 'sarah', email: 'sarah@gmail.com' });

ExampleForm.except('id')
/**
 * { name: 'sarah', email: 'sarah@gmail.com' }
*/

ExampleForm.except('id', 'name')
/**
 * { email: 'sarah@gmail.com' }
 */

`fill({ key: value, keyTwo: valueTwo, etc... })`

The fill method allows you to fill in new or empty values without overriding existing values:

const ExampleForm = form({ id: '', name: 'sarah', email: 'sarah@gmail.com' });

ExampleForm.fill({
    id: 2,
    name: 'tim',
    email: 'tim@gmail.com'
})

ExampleForm.all()
// { id: 2, name: 'sarah', email: 'sarah@gmail.com' }

`filled(propertyOne, propertyTwo, etc...)`

The filled method determine if a value is filled (AKA not empty):

const ExampleForm = form({ id: '', name: 'sarah', email: 'sarah@gmail.com' });

ExampleForm.filled('id', 'name') // false
ExampleForm.filled('name', 'email') // true

`forget(propertyOne, propertyTwo, etc...)`

The forget method will remove or "forget" a key value pair from the form input data

const ExampleForm = form({ id: '', name: 'sarah', email: 'sarah@gmail.com' });

ExampleForm.forget('id', 'name')
ExampleForm.all() // { email: 'sarah@gmail.com' }

`has(propertyOne, propertyTwo, etc...)`

The has method will determine if a key exists within the form input data

const ExampleForm = form({ id: '', name: 'sarah', email: 'sarah@gmail.com' });

ExampleForm.has('id', 'name') // true
ExampleForm.has('something', 'id', 'name') // false

`hasAny(propertyOne, propertyTwo, etc...)`

The hasAny method will determine if a key has any of the given properties within the form input data

const ExampleForm = form({ id: '', name: 'sarah', email: 'sarah@gmail.com' });

ExampleForm.hasAny('id', 'name') // true
ExampleForm.hasAny('something', 'id', 'name') // true

`input(property, default = false)`

The input method will resolve a given input value or default to false. You can define a default as the second parameter

const ExampleForm = form({ id: '', name: 'sarah', email: 'sarah@gmail.com' });

ExampleForm.input('id') // false
ExampleForm.input('id', 1) // 1
ExampleForm.input('name', 'tim') // sarah

`keys()`

The keys method will resolve an array of the input keys

const ExampleForm = form({ id: '', name: 'sarah', email: 'sarah@gmail.com' });

ExampleForm.keys() // ['id', 'name', 'email']

`macro(key, fn)`

The macro method can be used to extend upon the form object:

import form from 'vuejs-form';

form().macro('count', () => {
    return this.keys().length;
});

form().macro('mapInto', into => {
    return this.toArray().reduce((accumulated, { key, value }) => ({
            ...accumulated,
            ...into(key, value)
        }),
    {});
});

const ExampleForm = form({
    email: 'example@gmail',
    password: 'secret',
});

ExampleForm.mapInto((key, value) => ({ [`example_form_${key}`]: value }));
// { example_form_email: 'example@gmail.com', 'example_form_password': 'secret' };

View source on GitHub

`make({ ... })`

The make method will "make" a new form when used on the underlying class (With the proxy used on all forms)

import { VueForm } from 'vuejs-form'

const ExampleForm = VueForm.make({ id: '', name: 'sarah', email: 'sarah@gmail.com' })
ExampleForm.all() // { id: '', name: 'sarah', email: 'sarah@gmail.com' }

`missing(propertyOne, propertyTwo, ...)`

The missing method will determine if the form is missing the following properties

const ExampleForm = form({ id: '', name: 'sarah', email: 'sarah@gmail.com' })

ExampleForm.missing('id') // false
ExampleForm.missing('something') // true
ExampleForm.missing('name', 'email') // false
ExampleForm.missing('name', 'email', 'something') // true

`only(propertyOne, propertyTwo, ...)`

The only method will return an object of "only" the input properties you defined

const ExampleForm = form({ id: '', name: 'sarah', email: 'sarah@gmail.com' })

ExampleForm.only('name', 'email') // { name: 'sarah', email: 'sarah@gmail.com' }
ExampleForm.only('id', 'name') // { id: '', name: 'sarah' }
ExampleForm.only('id') // { id: '' }

`set({ key: value, keyTwo: valueTwo, etc... })`

The set method allows you to set new and override previous values:

const ExampleForm = form({ id: '', name: 'sarah', email: 'sarah@gmail.com' });

ExampleForm.set({
    id: 2,
    name: 'tim',
    email: 'tim@gmail.com',
    password: 'secret',
})

ExampleForm.all()
// { id: 2, name: 'tim', email: 'tim@gmail.com', password: 'secret' }

`toArray()`

The toArray method transforms the input into an array of key value pair objects:

const ExampleForm = form({ id: '', name: 'sarah', email: 'sarah@gmail.com' });

ExampleForm.toArray()
/**
    [
        { key: 'id', value: '' },
        { key: 'name', value: 'sarah' },
        { key: 'email', value: 'sarah@gmail.com' }
    ]
*/

`wrap(key)`

The wrap method allows you to wrap the input within a given object key:

const ExampleForm = form({ id: '', name: 'sarah', email: 'sarah@gmail.com' });

ExampleForm.wrap('data')
/**
  {
    data: {
        id: '',
        name: 'sarah',
        email: 'sarah@gmail.com'
    }
  }

Extend Form Using Macros

const form = require('vuejs-form');

form().macro('shortcut', () => {
    return this.validate().errors().list();
});  

let example = form({ name: '' }).rules({ name: 'required' });

example.shortcut();
// Output: ['Name is a required field'];

Extend Validator Using Macros

const { form, validator } = require('vuejs-form');

validator().macro('translate', ({ dictionary, locale }) => {
    if (!Object.keys(dictionary).includes(locale)) {
        console.warn(`Translation dictionary does not include passed ${locale}`);

        return this;
    } 

    const language = Object.keys(this.messages);
    const dictionary_words = key => Object.keys(dictionary[locale]).includes(key);
    language.filter(dictionary_words).forEach(key => { this.messages[key] = dictionary[`${locale}.${key}`] });

    return this;
});

let example = form({ name: '' }).rules({ name: 'required' });

let locale = 'ru';
let dictionary = { ru: { email: "Эл.почта" } };

example.validator().translate({ locale, dictionary });

Extending: Custom Error Messages

Customize error messages for specific rules on any given field

Globally, each rule provides a default error message
Easily override rule's default error message
Simply pass 'messages' to our validator
Only override messages you want to

let data = { name: '', email: '' };

let rules = {
    name: ['min:3', 'max:12', 'string', 'required'],
    email: ['email', 'required']
};

let customMessages = {
    'name.min': 'Whoops! :attribute is less than :min characters',
    'name.required': 'Wha oh, doesnt look like there any value for your :attribute field',

    'email.email': 'Really? Email is called Email...it has to be an email...',
};

form(data).rules(rules).messages(customMessages).validate().errors().all();

Extending: Custom Rules

Add Your Own Validation Rules

Easily add, or override, validation rules
Add a group of rules at a time
Add a single rule add a time

Extending: Custom Rules - Single Rule

form().validator().extend(rule_name, [message, rule])``js
let example = form({ name: 'timmy' }).rules({ name: 'uppercase' });

example.validator().extend('uppercase', [
':attribute must be uppercase',
({ value, validator, parameters }) => value === value.toUpperCase(),
]);

// true
example.validate().errors().has('name');

// "Name must be uppercase"
example.errors().get('name');
`

Extending: Custom Rules - multiple rules

form.validator().extend({ first: [message, rule], second: [message, rule], etc... })
`js
let example = form({ name: '' }).rules({ name: ['required_with:last_name', 'required' ] });

example.validator().extend({
uppercase: [
':attribute must be uppercase',
({ value }) => value === value.toUpperCase(),
],
not_uppercase: [
':attribute must not be uppercase',
({ value }) => value !== value.toUpperCase()
],
required_without: [
':attribute is only required when form is missing :required_without field',
({ validator, parameters }) => !Object.keys(validator.data).includes(parameters[0])
],
required_with: [
':attribute is required with the :required_with field',
({ validator, parameters }) => Object.keys(validator.data).includes(parameters[0])
],
});

LoginForm.toArray()
/**
[
{ key: 'name', value: 'jamie' },

/**

When dealing with HTML elements like checkboxes, your application may receive "truthy" values that are actually strings. For example, "true" or "on". For convenience, you may use the boolean method to retrieve these values as booleans. The boolean method returns true for 1, "1", true, "true", "on", and "yes". All other values will return false:
Boolean checks for */ LoginForm.boolean('name') // false

LoginForm.terms = true
LoginForm.boolean('terms') // true
LoginForm.terms = 'true'
LoginForm.boolean('terms') // true
LoginForm.terms = 'yes'
LoginForm.boolean('terms') // true
LoginForm.terms = 'on'
LoginForm.boolean('terms') // true
LoginForm.terms = "1"
LoginForm.boolean('terms') // true
LoginForm.terms = 1
LoginForm.boolean('terms') // true

/** Anything else will return false Ex: */
LoginForm.terms = 'asdfsdf'
LoginForm.boolean('terms') // false
`

Extend Form Functionality

`js
import form from 'vuejs-form'

form().macro('count', () => {
return this.keys().length
})

form().macro('mapInto', into => {
// NOTICE: this.data is where the input object is actually stored

this.data = Object.entries(this.data).reduce((input, [key, value]) => ({
        ...input,
        ...into(key, value)
    }),
{});

return this

})

const extendedForm = form({
email: 'example@gmail',
password: 'secret',
})

form().macro((key, value) => ({ [key]: value.split('@') })).all()
/**

{ email: ['example', 'gmail'], password: 'secret' } */ `
