*/
['form.data']: {
deep: true,

}
},

console.log('wrapped data: ', this.form.wrap('data'));

},
}
}
Validator Api
- form.rules({...})
- form.messages({...})
- form.validator(...)
- form.validate(...)
- form.hasValidator()
- form.setValidator({...})
Form Register Rules
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
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 runif (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
});

Extending the Error Bag
Error Bag Macro
Adds custom method on form error bag instance
let example = form(data).rules(rules);
let example.errors().macro('count', function () {
return this.list().length;
});
// example.errors().count() === example.errors().list().length
Error Bag ForceMacro
Allows you to overwrite pre-defined macro and over write core error message bag functions (Use With Caution)
let example = form({ name: '' }).rules({ name: 'required|min:3' }).validate();
example.errors().get('name'); // Outputs: "Name is a required field"
example.errors().forceMacro('get', function (field) {
if (this.has(field)) {
return this.list(field).join(', ') + '.';
}
});
example.errors().get('name'); // Outputs: "Name is a required field, name must have at least 3 characters."

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
forceMacro(key, fn)
forceMacro can be used to extend form object and FORCIBLY OVERWRITE base form behavior (Use VERY cautiously and prefer macro over forceMacro)
NOTE: Use forceLocalMacro if you only want to extend a specific form instance instead of all form instances.
import form from 'vuejs-form';
form().forceMacro('all', function () {
return this.keys().reduce((list, field) => ({
...list,
[field]: {
name: field,
value: this.data[field],
errors: this.errors().list(field),
}
}),
{});
})
form({ name: 'sam' }).rules({ name: 'required' }).validate();
# forceMacro implementation of form.all() Outputs
{
name: {
value: 'sam',
name: 'name',
errors: ['Name field is required']
}
}
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 the forms base behavior with custom methods/functions
NOTE: Use localMacro if you only want to extend a specific form instance instead of all form instances.
import form from 'vuejs-form';
form(data).macro('count', () => {
return this.keys().length;
});
// form.count() === form.keys().length
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
- Extend Validator Using Macros
- Extend Error Messages Bag Using Macros
- Add Custom Error Messages
- Create Custom Validation Rule
- Create Custom Validation Rules

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'];

});
let example = form({ name: '' }).rules({ name: 'required' });
let locale = 'ru';
let dictionary = { ru: { email: "Эл.почта" } };
example.validator().translate({ locale, dictionary });
Extending Error Messages Api
Error Bag Macro
Adds custom method on form error bag instance
let example = form(data).rules(rules);
let example.errors().macro('count', function () {
return this.list().length;
});
// example.errors().count() === example.errors().list().length
Error Bag ForceMacro
Allows you to overwrite pre-defined macro and over write core error message bag functions (Use With Caution)
let example = form({ name: '' }).rules({ name: 'required|min:3' }).validate();
example.errors().get('name'); // Outputs: "Name is a required field"
example.errors().forceMacro('get', function (field) {
if (this.has(field)) {
return this.list(field).join(', ') + '.';
}
});
example.errors().get('name'); // Outputs: "Name is a required field, name must have at least 3 characters."
Extending: Custom Error Messages
-
This has nothing to do with the error messages Api
-
These are the literal string output a rule message will display when it fails
-
Here we'll 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])`
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... })
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])
],
});
Extend Form Into Multi Step Form (Not tested, but good base to provide some ideas)

If you do so, don't plan on using the child component outside of multi-step forms. this.$parent is traditionally bad practice -->

Macros
Macros Overview
- Macros Are The Primary Way This Package And All Major Apis Are Extendable
- One of this packages primary goals is to be unbiased, but provide extreme extendability
- Macros, and specifically four types of macros, are the primary way we are able to obtain this goal
- Macros, in concept are extremely simple.
- They simply add functions, extending behavior
- Macros can accept arguments
- Macros have access to
this
within the callback you are registering - There are four types of macros.
- localMacro(name, fn) - extend instance with custom function (only the specific ) Simplest Example
form().hello(); // undefined
form().macro('hello', function () {
return 'world';
});
form().hello(); // 'world'
Extend Apis Via Macros
macro(name, fn)
- extend api with function
- instance gains functions and constructor prototype gain function
- applied to all new instances
- can not overwrite core functions
- can not overwrite pre-defined macros
- can not be applied on more than a single instance (Technically you can try, it just won't actually do anything the methods already added)
Example: macro() Simplify the validation process using a "completed" method wrapper
form().macro('completed', function () {
this.validate();
return this.errors().any() === false;
});
form({ name: '' }).rules({ name: 'required' }).completed(); // false
form({ name: 'samuel' }).rules({ name: 'required' }).completed(); // true
Extend Instances Via LocalMacros
localMacro(name, fn)
Example: See multi-step form example provided for forceLocalMacro
example. It provides a powerful example of possible ways to combine local and forceLocal macros.
- extend instance with function
- instance gains function
- NOT applied to all new instances
- can not overwrite core instances
- can not overwrite pre-defined macros
- can be applied on more than a single instance, but not automatically inherited globally Example: localMacro
Overwrite A Given Apis Core Via Force Macros
forceMacro(name, fn)
- overwrite core api or existing macros
- instance and constructor prototypes apply function
- applies on all instances
- can overwrite core functions
- can overwrite pre-defined macros NOTE: This is a very powerful function, use caution and when overriding core behavior understand things depend on other things under the hood. Only use this type of macro if no other macro solves your needs
Force Macro Example
Overwrite Error Message Apis Get Method To Get A Comma List Of Messages Instead Of The First Message
let example = form({ name: '' }).rules({ name: 'required|min:3' }).validate();
example.errors().get('name'); // 'Name field is required'
example.errors().forceMacro('get', function (field) {
if (this.has(field)) {
return this.list(field).join(', ');
}
});
example.errors().get('name'); // 'Name field is required, Name field must be more than 3 characters'
Overwrite A Given Instances Core Via Force Local Macros
forceLocalMacro(name, fn)
- overwrite instances core behavior or existing macros
- instance applies function
- not applied by all instances, only on single instance
- can overwrite core functions
- can overwrite pre-defined macros NOTE: Not quite as dangerous as forceMacro (it's only applied on one instance instead of globally across the api), it is still powerful and should be used only if localMacro doesn't solve your needs
Create A Parent Form With Multiple Child Forms Example uses localMacro & forceLocalMacro (Advanced example)
let MultiStepForm = form();
MultiStepForm.localMacro('register', function (children = []) {
this.current = 0;
const $parent = this;
// Set local macros on each one of the child forms
this.children = children.map(child => {
// 1. localMacro: parent() method references parent form will all steps
child.localMacro('parent', () => $parent);
// 2. forceLocalMacro: override validate() method to add in a step where child validate method populates parent() errors bag
// Below we'll override the parent validate() method using a forceLocalMacro as well to two way bind this setup
child.forceLocalMacro('validate', function () {
const childForm = this;
childForm.validator().validate();
childForm.parent().errors().set({
...childForm.parent().errors().all(),
...childForm.errors().all(),
});
return this;
})
});
/** Add helper methods for managing the multi-step form process **/
this.step = () => this.steps(this.current);
this.steps = index => index !== 'undefined' && this.hasStep(index) ? this.children(index) : this.children;
this.hasStep = index => typeof this.children[index] !== 'undefined';
this.prevStep = () => { this.current = this.current - 1; };
this.stepNumber = () => this.current + 1;
this.stepsCount = () => this.steps().length ;
this.hasPrevStep = () => this.hasStep(this.current - 1);
this.hasNextStep = () => this.hasStep(this.current + 1);
this.isLastStep = () => this.step() === this.steps(this.stepCount());
this.isFirstStep = () => this.step() === this.steps(0);
this.completedStepsCount = () => this.stepNumber();
this.remainingStepsCount = () => this.stepsCount() - this.stepNumber();
this.percentageCompleted = () => (this.completedStepsCount() / 100) * this.stepsCount();
this.percentageRemaining = () => (this.remainingStepsCount() / 100) * this.stepsCount();
this.next = () => {
if (this.hasNextStep()) this.current = this.current + 1;
};
this.prev = () => {
if (this.hasPrevStep()) this.current = this.current - 1;
};
this.to = index => {
if (this.hasStep(index)) this.current = index;
}
return this;
});
/** forceLocalMacro to overwrite default all method on MultiStepForm ~ aggregating all child form data **/
MultiStepForm.forceLocalMacro('all', function () {
return this.children.reduce((data, child) => ({
...data,
...child
}),
{});
});
/** forceLocalMacro to overwrite default validate method on MultiStepForm ~ setting all error messages **/
MultiStepForm.forceLocalMacro('validate', function () {
this.errors().set(
this.children.reduce((errors, child) => ({
...errors,
...child.validate().errors().all()
}),
{})
);
return this;
});
MultiStepForm.register([
form({ first_name: '', last_name: '' }).rules({ first_name: 'required', last_name: 'required' }),
form({ email: '', phone_number: '' }).rules({ email: 'required|email', phone: 'required|phone' }),
form({ password: null, password_confirmation: '' }).rules({ password: 'required|min:7|confirmed|string '}),
form({ terms_of_services: null }).rules({ terms_of_services: 'required|accepted' })
]);
MultiStepForm.validate().errors().list();
Output:
[
'First name is a required field',
'Last name is a required field',
'Email is a required field',
'Email must be an email',
'Phone number is a required field',
'Phone number must be a valid phone number',
'Password is a required field',
'Password must be at least 7 characters',
'Password must have the same value as the password confirmation field',
'Password must be a string',
'Terms Of Service is a required field',
'Terms Of Service has not been accepted, please accept to continue',
