Server setup

1. Clone the repository

2. Install required Node packages by running npm install in the directory

3. Install required Python packages from requirements.txt using pip install -r requirements.txt

4. Generate a keypair for the Push API

   # Source: https://tech.raturi.in/webpush-notification-using-python-and-flask?x-host=tech.raturi.in
   openssl ecparam -name prime256v1 -genkey -noout -out vapid_private.pem
   
   openssl ec -in ./vapid_private.pem -outform DER|tail -c +8|head -c 32|base64|tr -d '=' |tr '/+' '_-' >> private_key.txt
   openssl ec -in ./vapid_private.pem -pubout -outform DER|tail -c 65|base64|tr -d '=' |tr '/+' '_-' >> public_key.txt
   
   # Combine the keys into `keys.json` and delete the original files
   echo "{\"private\": \"$(cat private_key.txt)\", \"public\": \"$(cat public_key.txt | sed ':a;N;$!ba;s/\n/\\n/g')\"}" > keys.json && rm vapid_private.pem private_key.txt public_key.txt
   

5. Build the website assets using npm run build

6. Run the Flask webserver located in app/__init__.py (it is necessary to run the file itself at least once to create the required database tables)

You can run the development server with live-reload using npm run dev. You must however first run app/__init__.py to create the database tables.

Note that you may have issues getting the service worker to run outside localhost without an SSL certificate.
