``js
import validate, { required, min, max } from 'data-validations';

const data = { name: 'Rogan' };
const dataWithEmptyName = { name: '' };
const model = { name: [required('Name is required.')] };
const modelWithMinAndMax = {
name: [
min(6, 'Name must be at least 6 letters.'),
max(4, 'Name must have a maximum of 4 letters.')
]
};

validate(data, model); // { error: false, errors: {} }
validate(dataWithEmptyName, model); // { error: true, errors: { name: 'Name is Required.' } }
validate(data, modelWithMinAndMax) // { error: true, errors: { name: ['Name must be at least 6 letters.', 'Name must have a maximum of 4 letters.'] } }

If the validator returns undefined it means that the value is valid, and if return string it means that the value is invalid and the string is used as an error message.

- required: (message: String) => (value) => String | undefined
- object: (message: String) => (value) => String | undefined
- string: (message: String) => (value) => String | undefined
- func: (message: String) => (value) => String | undefined
- array: (message: String) => (value) => String | undefined
- date: (message: String) => (value) => String | undefined
- dateString: (message: String) => (value) => String | undefined
- boolean: (message: String) => (value) => String | undefined
- number: (message: String) => (value) => String | undefined
- integer: (message: String) => (value) => String | undefined
- float: (message: String) => (value) => String | undefined
- max: (maxLength: Integer, message: String) => (value) => String | undefined
- min: (minLength: Integer, message: String) => (value) => String | undefined
- oneOf: (options: Array, message: String) => (value) => String | undefined
- email: (message: String) => (value) => String | undefined
