# Create simple calibre server as user service (without sudo)

## warm up

- Install calibre via nix or pkg manager of choice
- Create library at prefered location where book going to be stored.
`mkdir -p /home/you/library`

- Add books to that location
`calibredb add /path/of/books.pdf --with-library /home/you/library`

# Main Course
- Create a systemd user service
In ~/.config/systemd/user create new file called calibre-server.service
`touch calibre-server.service`

- Write init script 
nvim calibre-server.service
```
[Unit]
Description=calibre content server

[Service]
Type=simple
ExecStart=/<path>/calibre-server --port=8180 --enable-local-write /home/you/library

[Install]
WantedBy=default.target
```
Note: remember to find the correct <path> of your calibre-server binary with `whereis calibre-server` command.

- Enabling the service
`systemctl --user enable calibre-server`

- Starting the service
`systemctl --user start calibre-server`

- Check the service running at `localhost:8180` in your browser

- Last but not least to run the service even after your user log out run this
`loginctl enable-linger username`

========================================================================================================================
# Optionals:

## Provide domain name for your service using reverse proxy

write nginx conf file
```
server {
    listen 10.0.0.20:80;
    server_name library.yourdomain.com;
    root /var/www/html;
    index index.html;
    location / {
        proxy_pass http://127.0.0.1:8180/;
    }
}
```

Now simply going to `https://library.yourdomain.com` you will reach to the calibre server without having to know backend hostname or port number.

## Have multiple libraries
- Inorder to have multiple libraries running on same server just add the different library path to the main command
i.e. `/<path/calibre-server --port=8180 --enable-local-write /home/you/library/fiction /home/you/library/tech`
