Logging

There is no stdout in the browser so the simplest way is to use the log crate with wasm-logger and console_error_panic_hook to see nicely formatted errors:

#[wasm_bindgen(start)]
pub fn main() {
    wasm_logger::init(wasm_logger::Config::default());
    console_error_panic_hook::set_once();

    // etc init and mounting of elements
    
    log::info!("it works!");
}
