Server setup

In order to use your calendar server with this app, you need to allow cross origin resource sharing for our hosts, allowing the common WebDAV/CalDAV methods and headers. The following is an Nginx config file that does this.

map $http_origin $allow_origin {
    ~^https?://(?:calendar\.(?:cza\.li|czarlie\.me)|czarlie.gilab.io)$ $http_origin;
}
map $http_origin $allow_methods {
    ~^(?:calendar\.(?:cza\.li|czarlie\.me)|czarlie.gilab.io)$ '
        GET, HEAD, POST, PUT, OPTIONS, MOVE, DELETE, COPY,
        LOCK, UNLOCK, PROPFIND, REPORT, MKCALENDAR
    ';
}
map $http_origin $allow_headers {
    ~^(?:calendar\.(?:cza\.li|czarlie\.me)|czarlie.gilab.io)$ '
        Authorization, Origin, X-Requested-With, Content-Type, Accept,
        DNT, X-CustomHeader, Keep-Alive, User-Agent, X-Requested-With,
        If-Modified-Since, If-Match, If-None-Match, Cache-Control,
        Content-Range, Range, Depth
    ';
}

server {
    server_name cal.cza.li;  # Replace with your server name

    location / {
        if ($request_method = OPTIONS) {
            add_header x-test 'test' always;
            add_header x-origin $http_origin always;

            add_header Access-Control-Allow-Origin $allow_origin always;
            add_header Access-Control-Allow-Methods $allow_methods always;
            add_header Access-Control-Allow-Headers $allow_headers always;

            add_header Vary 'Origin' always;

            return 204;
        }

        add_header Access-Control-Allow-Origin $allow_origin always;
        add_header Access-Control-Allow-Methods $allow_methods always;
        add_header Access-Control-Allow-Headers $allow_headers always;

        add_header Vary 'Origin' always;

        proxy_pass http://localhost:5232;  # Replace with your local server

        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Host $host;
        proxy_set_header Upgrade $http_upgrade;
    }
}
