Flask-Configurator

Env and file based configuration for Flask

Installation

pip install flask-configurator

Usage

from flask import Flask
from flask_configurator import Configurator

app = Flask(__name__)
Configurator(app)

By default this will load configuration from:

• environment variables with the FLASK_ prefix
• .env (only variables with the FLASK_ prefix)
• .env.ENV (only variables with the FLASK_ prefix)
• config.yml
• config.ENV.yml

Where ENV is the environment defined as defined by:

1. development if app.debug, production otherwise
2. FLASK_ENV environment variable
3. ENV key from any loaded file

Options

Configurator(
    app,
    default_file="config.yml", # default configuration file to load from (set to None to disable)
    env_prefix="FLASK", # environment variable prefix
    default_env="production", # default env name (None for default, False to not set any env)
)

Supported configuration formats: yml, json, toml.

Manual loading

Rather than going through an extension, you can use our custom Config class.

from flask_configurator import Config
config = Config()
config.load()
print(config["KEY"])
app.config.update(config)

Use it as your flask config class:

from flask import Flask
from flask_configurator import Config

class CustomFlask(Flask):
    config_class = Config

app = CustomFlask(__name__)
app.config.load()
