registerExceptionHandler

registerExceptionHandler is an essential function that must be invoked after calling setup in your application. It is used to register exit handlers for exceptions such as 'uncaughtException' and 'unhandledRejection'. You can see below how the function works under the hood.

/**
* Registers exception handlers for "uncaughtException" and "unhandledRejection"
*/
registerExceptionHandler() {
  const logFatalAndExit = err => {
    console.log('Encountered a fatal error. Check fatal log for details.')
    this.fatalLogger.fatal('unhandledRejection: ' + err.stack)
    // this.exitHandler.exitCleanly()
    this.exitHandler.exitUncleanly()
  }
  process.on('uncaughtException', err => {
    logFatalAndExit(err)
  })
  process.on('unhandledRejection', err => {
    logFatalAndExit(err)
  })
}
