Python as a Backend: Flask

1. Create a Flask API

   • You can choose what it does!
   • Your API should respond to at least one GET and one POST request
   • Add at least one extension eg. a database connection or an email service
   • Follow documentation to add some tests using pytest

2. Prepare a short (3-5 minute) demonstration of your new API

   • Focus on demonstrating your API's functionality
   • You could demonstrate using curl, Hoppscotch, a custom client or a combination!

• cd flask-demo
• pipenv install -r requirements.txt
• pipenv shell
• Tell terminal which application to work with:
  • export FLASK_APP=server.py (Linux/MacOS/GitBash)
  • set FLASK_APP=server.py (Windows Command Prompt)
  • $env:FLASK_APP = "server.py" (PowerShell)
• Tell terminal which environment to work in:
  • export FLASK_ENV=development (Linux/MacOS/GitBash)
  • set FLASK_ENV=development (Windows Command Prompt)
  • $env:FLASK_ENV="development" (PowerShell)
• flask run
