Python Flask is a popular web framework for developing web applications, APIs, etc. Running flask apps on the local machine is very simple, but when it comes to sharing the app link to other users, you need to setup the whole app on another laptop. This article provides an interesting way to setup your web app online. Then, you can send the link to your peers before deploying it. Generally while running flask apps from our local machine we need to use LOCAL-HOST, but services such as google colab provides VM(virtual machine) hence we do not access the local-host. We will use it in to a public URL using ngrok. The Python library flask-ngrok.
Installation –
Run from your terminal –
pip install flask-ngrok
Create a Flask App –
Now create a simple Flask application app.py –
Python3
from flask import Flask from flask_ngrok import run_with_ngrok app = Flask(__name__) run_with_ngrok(app) @app.route("/") def hello(): return "Hello Geeks!! from Google Colab" if __name__ == "__main__": app.run() |
Run the app –
Run the app using –
python run.py
After clicking on the secure URL provided by ngrok in terminal, you can access your application –
Here You go!!
Now you can use this URL on Google-colab or anywhere to access your running app.
