How to do selects and inserts in MongoDB from the frontend?
Hello,
There was a need to make queries, inserts in MongoDB. I re-read the info on the net, they mostly talk about node.js (as for me, this is already a backend ..). I myself don’t know much js and I wouldn’t want to complicate everything with nod. PHP - definitely does not fit the requirements.
Perhaps there is an easy and elegant way to interact with Mongo through something that is not very convoluted?
If possible, it would be very cool if someone would describe step by step with references how and what, or at least draw the basic principle of interaction'a.
Thank you!
