- Sending data to servers when a user leaves a website can be unreliable with traditional methods like XMLHTTPRequest or fetch in beforeunload or unload events.
- The Beacon API provides a more reliable way to send data as it allows the browser to send requests without waiting for a response, making it ideal for analytics or auto-logout features.
- Beacon API is simple to use, supports only POST requests, and has limitations on the amount of data that can be sent, but it's perfect for sending small, important messages when a page closes.
- It can also be used for syncing backend with frontend without waiting for server responses, making it useful for scenarios like analytics where immediate feedback isn't necessary.
