Creating a global function execution queue on nodejs (expressjs/mongo)?

Question

MongoDB

Good day! Help plz with this problem.
I am developing an application on the express/mongo stack. There is a function for generating images, I want to make a global queue so that more than 100 items for all users cannot be generated at the same time, how is it better to implement this? It is desirable that this works in conjunction with mongo, so that you can administer the queue from under the UI.

In general, I implemented it using db.collection.watch() and the p-queue package. Thanks to all))
