        The `dataclass-type-validator` is a type validation library for the properties of `dataclasses.dataclass` using Python type hint information.
        
        ## Installation
        
        `pip install dataclass-type-validator` or add `dataclass-type-validator` line to `requirements.txt`
        
        ## A Simple Example
        
        
        ```python
        from dataclasses import dataclass
        from typing import List
        from dataclass_type_validator import dataclass_type_validator
        from dataclass_type_validator import TypeValidationError
        
        @dataclass()
        class User:
            id: int
            name: str
            friend_ids: List[int]
        
            def __post_init__(self):
                dataclass_type_validator(self)
        
        
        # Valid User
        User(id=10, name='John Smith', friend_ids=[1, 2])
        # => User(id=10, name='John Smith', friend_ids=[1, 2])
        
        # Invalid User
        try:
            User(id='a', name=['John', 'Smith'], friend_ids=['a'])
        except TypeValidationError as e:
            print(e)
        # => TypeValidationError: Dataclass Type Validation (errors = {
        #   'id': "must be an instance of <class 'int'>, but received <class 'str'>",
        #   'name': "must be an instance of <class 'str'>, but received <class 'list'>",
        #   'friend_ids': 'must be an instance of typing.List[int], but there are some errors:
        #       ["must be an instance of <class \'int\'>, but received <class \'str\'>"]'})
        ```
