🔮 Overview
⚙️ Installation
👩🏻‍💻 Usage

🔮 Overview
poetry-plugin-dotenv - is the plugin that automatically loads environment variables from a dotenv file into the environment before poetry commands are run.
This plugin doesn't have any dependencies, but therefore it also supports features that python-dotenv supports (e.g. templates, interpolating variables using POSIX variable expansions etc).
⚙️ Installation
poetry self add poetry-plugin-dotenv

👩🏻‍💻 Usage
By default, plugin will load the .env file from the current working directory or "higher directories".
To prevent poetry from loading the dotenv file, set the POETRY_DONT_LOAD_DOTENV environment variable.
If your dotenv file is located in a different path or has a different name you may set the POETRY_DOTENV_LOCATION environment variable.

# .env

DB__DBNAME=prod

DB__HOST=localhost
