v1.0.0-beta2

Changes

• fix array rule return value issue.

v1.0.0-beta1

The full library has been rewritten. It uses code generators in order to be much faster.

Breaking changes

This new version contains several breaking changes.

Rule logic changed

The rule codes have been rewritten to code generator functions. Therefore if you use custom validators, you should rewrite them after upgrading.

Convert values

The number, boolean and date rules have a convert: true property. In the previous version it doesn't modify the value in the checked object, just converted the value to the rules. In the version 1.0 this property converts the values in the checked object, as well.

New

Sanitizations

The sanitization function is implemented. There are several rules which contains sanitizers. Please note, the sanitizers change the original checked object values.

Rule	Property	Description
boolean	convert	Convert the value to a boolean.
number	convert	Convert the value to a number.
date	convert	Convert the value to a date.
string	trim	Trim the value.
string	trimLeft	Left trim the value.
string	trimRight	Right trim the value.
string	lowercase	Lowercase the value.
string	uppercase	Uppercase the value.
string	localeLowercase	Lowercase the value with String.toLocaleLowerCase.
string	localeUppercase	Uppercase the value with String.toLocaleUpperCase.
string	padStart	Left padding the value.
string	padEnd	Right padding the value.
string	convert	Convert the value to a string.
email	normalize	Trim & lowercase the value.
forbidden	remove	Remove the forbidden field.
object	strict: "remove"	Remove additional properties in the object.
*	default	Use this default value if the value is null or undefined.

Root element validation

Basically the validator expects that you want to validate a Javascript object. If you want others, you can define the root level schema, as well. In this case set the $$root: true property.

Example to validate a string variable instead of object

const schema = {
    $$root: true,
    type: "string", 
    min: 3, 
    max: 6
};

v.validate("John", schema); // Valid
v.validate("Al", schema); // Fail, too short.

Enhanced shorthand types

You can use string-based shorthand validation definitions in the schema with properties.

{
    password: "string|min:6",
    age: "number|optional|integer|positive|min:0|max:99",

    retry: ["number|integer|min:0", "boolean"] // multiple types
}

Other changes

New equal rule

It checks the value equal (==) to a static value or another property. The strict property uses === to check values.

Example with static value:

const schema = {
    agreeTerms: { type: "equal", value: true, strict: true } // strict means `===`
}

v.validate({ agreeTerms: true }, schema); // Valid
v.validate({ agreeTerms: false }, schema); // Fail

Example with other field:

const schema = {
    password: { type: "string", min: 6 },
    confirmPassword: { type: "equal", field: "password" }
}

v.validate({ password: "123456", confirmPassword: "123456" }, schema); // Valid
v.validate({ password: "123456", confirmPassword: "pass1234" }, schema); // Fail

properties in object rule

You can use the properties property besides the props property in the object rule.
