How to competently implement the service architecture for Instagram on NodeJS?

Question

Node.js

The task is to implement a cloud service with which users can automate the process of completing tasks on Instagram, that is, likes on hashtags, on geolocations, comment on posts, and so on.
Examples of such services: https://tooligram.com/ https://clientogram.ru/ instaplus.me
How can you competently implement the server part on NodeJS, which will perform the assigned tasks, that is, find new posts, put likes?
If about 3000 such tasks are launched, then why not create three thousand asynchronous ones?
Considering that there is a limit on the number of requests, it is possible to execute such functions in a row in one thread, now I don’t fully understand how to do it)

In one answer, directly describe how to make a bot for insta?
First you need to google how to work with Instagram in general.
Surely there are a couple of ready-made libraries.
Come up with a database structure.
Then learn nodejs and how to run tasks in turn q/defered/async etc.
Then blind the found libs and queues together.
Hang it all to work in the background.
