unhandled

Adds handlers for the uncaughtException, unhandledRejection, SIGINT, and SIGTERM events. The default behavior is to log the event to console (and the error, if applicable), then exit with code 1`.

The logger, exit code, and optional handler(s) can be configured

• options.rejection.handler: ({ event, error }) => nil | Custom, synchronous action to run on unhandled promise rejection (supercedes options.handler).
• options.rejection.ignore: boolean = false | Do not handle rejections (permit default runtime behavior).
• options.sigint.exit: boolean | Exit on SIGINT event (supercedes options.exit).
• options.sigint.handler: ({ event }) => nil | Custom, synchronous action to run on SIGINT signal (supercedes options.handler).
• options.sigint.ignore: boolean = false | Do not handle SIGINT (permit default runtime behavior).
• options.sigterm.exit: boolean | Exit on SIGTERM event (supercedes options.exit).
