Rules

Additional rules.

E-mail

The rule checks an E-mail validness.

import { v9s, simplify } from 'v9s';
import { email } from 'v9sx';

const check = simplify(v9s(false).use(email));

console.log(check('[email protected]')); // true
console.log(check('example.com')); // false

Float string

The rule checks a float string validness.

import { v9s, simplify } from 'v9s';
import { float } from 'v9sx';

const check = simplify(v9s(false).use(float));

console.log(check('123.60')); // true
console.log(check('-123.60')); // true
console.log(check('+123.60')); // false
console.log(check('123')); // true
console.log(check('123,60')); // true
console.log(check('1 123.60')); // false

HEX string

The rule checks the validness of a lowercase HEX string.

import { v9s, simplify } from 'v9s';
import { hex } from 'v9sx';

const check = simplify(v9s(false).use(hex));

console.log(check('123abc')); // true
console.log(check('123ABC')); // false

Integer string

The rule checks an integer string validness.

import { v9s, simplify } from 'v9s';
import { integer } from 'v9sx';

const check = simplify(v9s(false).use(integer));

console.log(check('123456')); // true
console.log(check('123 456')); // false
console.log(check('-123456')); // true
console.log(check('123,456')); // false

Russian postal code

The rule checks a Russian postal code validness.

import { v9s, simplify } from 'v9s';
import { ruPostalCode } from 'v9sx';

const check = simplify(v9s(false).use(ruPostalCode));

console.log(check('123456')); // true
console.log(check('123-456')); // false

Modifiers

Data modifiers.

Compact

Removes space characters inside a value.

import { v9s, simplify } from 'v9s';
import { compact } from 'v9sx';

const check = simplify(v9s(false).use(compact));

console.log(check('1 \t 234 567')); // '1234567'

Replace factory

Returns a modifier function that replaces a substring.

import { v9s, simplify } from 'v9s';
import { replaceFactory } from 'v9sx';

To lower case

Modifies a value to lowercase.

import { v9s, simplify } from 'v9s';
import { toLowerCase } from 'v9sx';

const check = simplify(v9s(false).use(toLowerCase));

console.log(check('ABCDEFГДЕЁЖ')); // 'abcdefгдеёж'

To upper case

Modifies a value to uppercase.

import { v9s, simplify } from 'v9s';
import { toUpperCase } from 'v9sx';

const check = simplify(v9s(false).use(toUpperCase));

console.log(check('abcdefгдеёж')); // 'ABCDEFГДЕЁЖ'

Trim end

Removes spaces at the beginning of a value.

import { v9s, simplify } from 'v9s';
import { trimEnd } from 'v9sx';

const check = simplify(v9s(false).use(trimEnd));

console.log(check('  \t   hello, world!   \t ')); // '  \t   hello, world!'

Trim start

Removes spaces at the end of a value.

import { v9s, simplify } from 'v9s';
import { trimStart } from 'v9sx';

const check = simplify(v9s(false).use(trimStart));

console.log(check('  \t   hello, world!   \t ')); // 'hello, world!   \t '

Trim

Removes the leading and trailing white space and line terminator characters from a string.

import { v9s, simplify } from 'v9s';
import { trim } from 'v9sx';

const check = simplify(v9s(false).use(trim));
