I look for a good tutorial to node.js and mongoDB - what will i do?

I want to develop a stock monitoring with over 10000 stocks under node.js and mongoDB!
Every 2-3 hours a task should search certain websites for information about the individual shares - so I need a fast algorithm - which runs through all shares in the database every few hours and searches for certain keywords in corresponding websites!
Unfortunately I can’t find a description anywhere - how I can best run through the stock table from start to finish - without using too much memory - who can help?
Thanks in advance for your help!
Best regards

Hi @Mar_Bot and welcome to the MongoDB Community forum!!

To get started with using MongoDB with Node js, the blog post would be a good starting point to start the project.

You can also take a look at documentation for building better query performance to optimise the query and eventually the performance of the application.

But it would be helpful for us if you could share some more details on the requirements here.

However, to run an operation for every 2-3 hours, you can use the Atlas Trigger features.

Let us know if you have further questions

Best regards
