Installation

npm install another-fluent-validator

Examples

fluent interface

const FluentValidator = require('another-fluent-validator')

// example object
const myDirtyObject = {
  code: 'ABC'
  name: '',
  value: '123'
}

let code = new FluentValidator(myDirtyObject.code, 'my code')
  .isString()
  .isNotEmpty()
  .value
// -> wil set code to 'ABC'

let name  = new FluentValidator(myDirtyObject.name, 'my name')
  .isString()
  .isNotEmpty()
  .hasMinimumLength(3)
  .value
// -> will throw Error with message: "my name should not be empty"

let value  = new FluentValidator(myDirtyObject.value, 'my value')
  .toInteger()
// -> checks if "isNumeric" and casts to number (value = 123)
}

static interface

Cant be use as pre-check (e.g. only validate when defined)

FluentValidator.isArray('abc') // -> returns false
