A library of string validators.

Installation and Usage

Function

| Validator | Description | |---------------------------|---------------------------------------| | isAddress(str) | check if a string is a address. | | isBoolean(str) | check if a string is a boolean. | | isInt8(str) | check if a string is a int8. | | isUint8(str) | check if a string is a uint8. | | isBytesN(str) | check if a string is a BytesN, N:1-32 | | isByte(str) | check if a string is a Bytes1 | | isBytes(str) | check if a string is a Byte1 ~ Byte32 | | isValid(type, str) | check if a string is match the type | | getRange(type) | get type MIN and MAX range | | getMessage(type, str) | get valid message |

Example

var validator = require('solidity-validator');

validator.isAddress('0xa77451687Ee77cB3DFf16A24446C54DB76C80222'); // true
validator.isAddress('0xa77451687Ee77cB3DFf16A24446C54DB76C80223'); // false

validator.isBoolean('true'); // true
validator.isBoolean('false'); // true
validator.isBoolean('1'); // false
validator.isBoolean('0'); // false

validator.isInt8('-128'); // true
validator.isInt8('127'); // true
validator.isInt8('128'); // false

validator.isUint8('0'); // true
validator.isUint8('255'); // true
validator.isUint8('0.1'); // false
validator.isUint8('-1'); // false
validator.isUint8('256'); // false

validator.isBytes1('0x00'); // true
validator.isBytes1('0xff'); // true
validator.isBytes1('0xgg'); // false
validator.isBytes1('0x'); // false
validator.isBytes2('0x0000'); // true
validator.isBytes2('0xffff'); // true
validator.isBytes2('0xgggg'); // false
validator.isBytes2('0xff'); // false

validator.isByte('0x00'); // true
validator.isByte('0xff'); // true
validator.isByte('0xgg'); // false
validator.isByte('0x'); // false

validator.isBytes('0x00'); // true
validator.isBytes('0xffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff'); // true
validator.isBytes('0xgg'); // false
validator.isBytes('0xffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff'); // false

validator.isValid('uint', "123"); // true
validator.isValid('uint', "280"); // false
validator.isValid('address', "ooooooxxxxx"); // false

validator.getMessage('uint8', '255');
validator.getMessage('address', '0xa77451687Ee77cB3DFf16A24446C54DB76C80222');
validator.getMessage('int8', '129'); // The value is an illegal range.
validator.getMessage('uint8', '256'); // The value is an illegal range.
validator.getMessage('bool', '0'); // The value is not a boolean.

validator.getMessage('byte', '0x01')
validator.getMessage('bytes2', '0x01')
validator.getMessage('bytes2', '0x0101')

validator.getMessage('address', 'oooooxxxx'); // The value is not a valid address.
validator.getMessage('byte', 'oooooxxxx'); // The value is not a valid bytes.

validator.getRange('int8');

/* === output ===
{
  MIN: -128,
  MAX: 127
}
