A successor to flask-ngrok and flask-ngrok2 for demo Flask apps using ngrok.
Project description
flask-ngrok3
The successor for flask-ngrok and flask-ngrok2 for making demo Flask apps from personal machine.
Compatability
Python 3.6+ is required.
Installation
pip install flask-ngrok3
Inside Jupyter / Colab Notebooks
Notebooks have an issue with newer versions of Flask, so force an older version if working in these environments.
!pip install flask==0.12.2
See the example notebook for a working example.
Quickstart
- Import with
from flask_ngrok3 import run_with_ngrok
- Add
run_with_ngrok(app)
to make your Flask app available upon running - Now you can run with your custom host
app.run(host='192.168.1.5')
- Also, you can get ngrok address on startup
# flask_ngrok3_example.py
from flask import Flask
from flask_ngrok3 import run_with_ngrok, get_host
app = Flask(__name__)
run_with_ngrok(app) # Start ngrok when app is run
@app.route("/")
def hello():
return "Hello World!"
def get_ngrok_host():
print(f"ngrok host is: {get_host()}")
app.before_first_request(get_ngrok_host) # Register function for run before the first request
if __name__ == '__main__':
app.run()
