Best exit for this case

[fzn0x]

I was doing data scrapping with a lot of async operation, the screenshot above show you that my scrapper is done with the async operation but if I exit normally, I will miss some data to get inserted, what is best practice for this case?

let waitingInsert = data.length;
// a loop which call the waitForGuildInsert function
async function waitForGuildInsert() {
  waitingInsert--;
  if (waitingInsert === 0) {
    console.log(`Total inserted: ${insertedGuilds.length}`);
    await guildModel.bulkInsertOrUpdate(insertedGuilds); // Model
  }
}

Thank you!

Solution: use before exit

process.on('beforeExit', async () => {
    await something()
    process.exit(0) // if you don't close yourself this will run forever
});
