• Ability to dump modified configurations back to JSON

    host: str = 'localhost' # default value must be provided
    port: int = 3306
    user: str = 'root'
    password: str = 'password'


config = JSDC_Loader('config.json', DatabaseConfig)
print(config.host)

Example 2

from dataclasses import dataclass, field
