A simple way to demo Flask apps from your machine.
A simple way to demo Flask apps from your machine. Makes your Flask apps running on localhost available over the internet via the excellent ngrok tool.
Python 3.6+ is required.
pip install flask-ngrok
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
from flask_ngrok import run_with_ngrok
run_with_ngrok(app)
to make your Flask app available upon running# flask_ngrok_example.py
from flask import Flask
from flask_ngrok import run_with_ngrok
app = Flask(__name__)
run_with_ngrok(app) # Start ngrok when app is run
@app.route("/")
def hello():
return "Hello World!"
if __name__ == '__main__':
app.run()
Running the example:
python flask_ngrok_example.py
