lastcall

Appearance

Exception capture ​

Optional automatic shutdown on unhandled errors:

ts
const lastcall = createLastcall({
  captureUncaughtException: true,
  captureUnhandledRejection: true,
});

When enabled, uncaughtException or unhandledRejection triggers the same shutdown flow as SIGTERM.

Default: disabled ​

By default lastcall does not capture these events — Node.js default behavior is preserved.

When to enable ​

Enable in long-running production services where any fatal error should trigger cleanup:

ts
createLastcall({
  captureUncaughtException: true,
  captureUnhandledRejection: true,
  logger: (msg, meta) => pino.error(meta, msg),
});

Interaction with exit code ​

Shutdown triggered by an exception still runs all handlers. Exit code depends on handler results (critical failures → 1).
