Run Flask and test it out
- Open a terminal in Visual Studio Code.
- cd into the projects directory:
cd /home/coder/project - install virtualenv:
python3 -m pip install virtualenv - create a virtualenv:
/home/coder/.local/bin/virtualenv VENV - source the virtualenv (activate it):
source VENV/bin/activate - cd into the projects directory:
cd /home/coder/project - source the virtualenv (activate it):
source VENV/bin/activate - cd into flask project:
cd /home/coder/project/flask-project - install software:
make install - run flask:
python main.py
You should see something similar to this:
(VENV) coder@81b962f86a39:~/project/flask-project$ python main.py * Serving Flask app "main" (lazy loading) * Environment: production WARNING: This is a development server. Do not use it in a production deployment. Use a production WSGI server instead. * Debug mode: on * Running on http://127.0.0.1:5000/ (Press CTRL+C to quit) * Restarting with stat * Debugger is active! * Debugger PIN: 325-940-967
Now open up browser preview and test out the routes. By typing in the following:
http://127.0.0.1:5000/ http://127.0.0.1:5000/echo/hello
Notice how the print messages in the flask app display in the running logs. Try changing the print statements and watch the running application update in real-time.
