Enumeration CommandEventName

Events dispatched by the commandbus event middleware.

The command bus dispatches events at key points in the command lifecycle, allowing you to observe command execution, access results, handle errors, or even prevent commands from executing.

Example

// Listen for command results
document.addEventListener(CommandEventName.Handled, (event: CommandEvent) => {
    console.log('Command executed:', event.detail.command);
    console.log('Result:', event.detail.result);
});

// Handle command errors
document.addEventListener(CommandEventName.Failed, (event: CommandEvent) => {
    console.error('Command failed:', event.detail.error);
});

// Prevent a command from executing
document.addEventListener(CommandEventName.Received, (event: CommandEvent) => {
    if (shouldBlockCommand(event.detail.command)) {
        event.preventDefault();
    }
});
