+## Database Pool as state
+
+Rather to have a simple Mutex for the state, database can be used. 
+
+```
+sqlx = { version = "0.6", features = [ "runtime-tokio-rustls", "postgres" ] }
+```
+
+```rs
+let con_string = format!("postgres://postgres:postgres@localhost/postgres");
+let db = PgPoolOptions::new()
+	.max_connections(5)
+	.connect(&con_string)
+	.await
+	.expect("Cannot create PgPool");
+
+let arc_db = Arc::new(db);
+```
+

+```rs
+tauri::Builder::default()
+	.manage(arc_db)
