Package Exports
- solidity-validator
This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (solidity-validator) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.
Readme

A library of string validators.
Installation and Usage

| 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 |
