How to build a web framework with Flask
Solution
Building a web framework with Flask involves several steps. Here's a basic guide:
-
Installation: First, you need to install Flask. You can do this using pip, a package manager for Python. Open your terminal and type
pip install flask. -
Setting up a basic application: After installing Flask, you can set up a basic application. Create a new Python file, for example,
app.py, and add the following code:
from flask import Flask
app = Flask(__name__)
@app.route('/')
def home():
return "Hello, World!"
if __name__ == '__main__':
app.run(debug=True)
-
Running the application: You can run the application by typing
python app.pyin the terminal. You should see output telling you that the server is running. You can visithttp://127.0.0.1:5000/in your web browser to view your application. -
Building out your application: From here, you can start building out your application. You might add more routes, templates, and data storage, depending on what you want your application to do. Flask has a lot of functionality that you can use to build your application, including support for cookies, sessions, and message flashing.
-
Testing your application: Flask also has support for unit testing, which you can use to test your application and make sure everything is working as expected.
-
Deployment: Once you're happy with your application, you can deploy it to a server so that other people can use it. There are many options for deploying Flask applications, including Heroku, AWS, and Google Cloud Platform.
Remember, this is a very basic guide. Building a web framework with Flask can get much more complex depending on the needs of your application.

Now that you have your development environment set up, let’s get your production application server set up with Gunicorn on web-01, port 5000. You’ll need to install Gunicorn and any libraries required by your application. Your Flask application object will serve as a WSGI entry point into your application. This will be your production environment. As you can see we want the production and development of your application to use the same port, so the conditions for serving your dynamic content are the same in both environments.Requirements:Install Gunicorn and any other libraries required by your application.The Flask application object should be called app. (This will allow us to run and check your code)You will serve the same content from the same route as in the previous task. You can verify that it’s working by binding a Gunicorn instance to localhost listening on port 5000 with your application object as the entry point.In order to check your code, the checker will bind a Gunicorn instance to port 6000, so make sure nothing is listening on that port.Example:Terminal 1:ubuntu@229-web-01:~/AirBnB_clone_v2$ gunicorn --bind 0.0.0.0:5000 web_flask.0-hello_route:app[2019-05-03 20:47:20 +0000] [3595] [INFO] Starting gunicorn 19.9.0[2019-05-03 20:47:20 +0000] [3595] [INFO] Listening at: http://0.0.0.0:5000 (3595)[2019-05-03 20:47:20 +0000] [3595] [INFO] Using worker: sync[2019-05-03 20:47:20 +0000] [3598] [INFO] Booting worker with pid: 3598Terminal 2:ubuntu@229-web-01:~$ curl 127.0.0.1:5000/airbnb-onepage/Hello HBNB!ubuntu@229-web-01:~$
