Enviparse

Description

Enviparse let you simply create dataclasses from environment variable.

Supported types are :

• int
• float
• str
• bool
• optional
• list
• enum (with int or string values only)
• @attr annotated class
• @dataclasses.dataclass annotated class

Example

With following environment variables :

DATABASE_CONFIG_USERNAME=postgres
DATABASE_CONFIG_PASSWORD=password
DATABASE_CONFIG_HOST=127.0.0.1
DATABASE_CONFIG_PORT=5432
DATABASE_CONFIG_DATABASE_NAME=appdb

You can parse environment variable with :

import dataclasses
from enviparse import Enviparse


@dataclasses.dataclass
class DatabaseConfig:
    username: str
    password: str
    host: str
    port: int
    database_name: str


db_config = Enviparse().parse("DATABASE_CONFIG", DatabaseConfig)
print(db_config)

You should get the following result :

DatabaseConfig(username='postgres', password='password', host='127.0.0.1', port=5432, database_name='appdb')
