Pre-requisites

To try out Flask-Unleash, you'll need an instance of the Unleash server. You can either use:

• Spin up a stack in Docker Compose using unleash-docker
• Check out the demo at Unleash-Hosted

Quickstart

Install Flask-Unleash using pip.

pip install Flask-Unleash

Next, add Flask-Unleash to your code.

from flask import Flask
from flask_unleash import Unleash

app = Flask(__name__)
app.config["UNLEASH_URL"] = "http://localhost:4242/api"
app.config["UNLEASH_APP_NAME"] = "demoapp"
unleash = Unleash(app)

Now you can use the client to check feature flags

flag_value_1 = unleash.client.is_enabled("simple-feature")

# You can pass in a context object (https://unleash.github.io/docs/unleash_context) for more complex features.
context = {
    'userId': 'hamster@hamster.com'
}
flag_value_2 = unleash.client.is_enabled("complex-feature", context)

Check out the demo app for a more real-life sample implementation.
