graceful-shutdown

To prevent data loss during application shutdown, you can handle SIGTERM and SIGINT signals by intercepting them to track in-flight asynchronous tasks, drain buffers, and execute resource cleanup callbacks before the process terminates.

The best way to drain buffers and close connections before exit is to register cleanup callbacks with a shutdown handler that intercepts process signals, ensuring pending data is flushed and final resource cleanup executes before termination.

You track in-flight asynchronous tasks by registering them with a shutdown manager that monitors their status upon receiving a signal, ensuring they either complete successfully or time out before the application terminates.

Yes, this graceful shutdown handler supports both TypeScript/JavaScript and Python environments, allowing you to manage orderly application termination, signal handling, and resource cleanup across both tech stacks.

Background workers lose queued items when terminating because pending tasks are abruptly killed. You can ensure processing finishes by using a shutdown handler to intercept signals, track active jobs, and wait for them to complete before exiting.
