Sentinel

Typescript validation library

Overview

Sentinel provides lots of validations

Single validation:

const isValidNumber: boolean = new Sentinel(36, [Sentinel.isNumber]).isValid()

Multiple validations (all must be valid):

const isValidNumberGreaterThan10 = new Sentinel(15, [Sentinel.isNumber, Sentinel.isGreaterThan(10)]).isValid()

// Same results:

const isValidNumberGreaterThan10 = new Sentinel(15, Sentinel.all(Sentinel.isNumber, Sentinel.isGreaterThan(10))).isValid()

// isInvalid()
const isInvalidNumberGreaterThan100 = new Sentinel(15, [Sentinel.isNumber, Sentinel.isGreaterThan(100)]).isInvalid()

Multiple validations (at least one must be valid):

const validContact = new Sentinel('john@doe.com', Sentinel.any(Sentinel.isEmail, Sentinel.isBrazilianCellPhone(true))).isValid()

Available validations:

Method	Assertation
isArray	Check if passed value is an array
isNumber	Check if passed value is a number
isRequired	Check if passed value is present
isPresent	Alias for isRequired
hasValue	Alias for isRequired
hasMinLength(size)	Checks if string value has at least size chars
hasMaxLength(size)	Checks if string value has maximum of size chars
hasMinMaxLength(min, max)	Checks if string value has between min and max chars
hasExactLength(size)	Checks if string value has exact size chars
isLessThan(num)	Checks if number value is smaller than num
isLessOrEqualThan(num)	Checks if number value is smaller than or equal to num
isGreaterThan(num)	Checks if number value is bigger than num
isGreaterOrEqualThan(num)	Checks if number value is bigger than or equal to num
isEmail	Check if passed value is a valid email based on RFC 5322
isDate(format = undefined)	Check if passed value is a valid date
isDateGreaterThan(referenceDate)	Check if date is bigger than referenceDate
isPasswordValid(lowerPresent = true, upperPresent = true, numberPresent = true, specialPresent = true, minimumRules = 3, minChars = 8)	Checks if at least minimumRules are valid, considering boolean options: lowerPresent, upperPresent, numberPresent, specialPresent. Password must be minChars long.
isCpfValid	Validates brazilian CPF
isUSZipCodeValid	Validates US zip codes
isBRZipCodeValid	Validates brazilian zip vodes
isZipCodeValid	Validates US and brazilian zip codes
isBRPhoneValid	Validates brazilian phones
isBRCellPhoneValid	Validates brazilian cellphones

Compositions

Method	Assertion
Sentinel.all	All checks must be valid
Sentinel.any	One check must be valid

Methods

Method	Assertion
isValid	Return if assertions were validated
isInvalid	Return if assertions were not validated

Roadmap

• Modularize validations
• Modularize locale based validations
