使用Node.js的提醒机器人

Question

I am creating reminder bot. User inputs date eg 01.01.19, I'm using new Date() to get milisecs to event, then I call setTimeout() function and wait until it happens. So the problem is about setTimeout() Is it OK to call it for a long period of time and many times? If user will call it for eg 10000 times, will it break my bot and so on? Is it optimal case or you can advice something else

Answer 1

Well since you have a database, just do the following:

1. When the user clicks the button, add a new reminder in the database
2. Have an interval timer that constantly iterates through all items in the database and checks if they have passed their time yet
3. Show those ones that need to be reminded.

Should be pretty simple to do - just use setInterval , a loop, and a little bit of working with Date in JavaScript.
