qache VS Lowdb

For 1: Don't.* For 2: You're looking for a cache. I've published an OS npm module. Looking at the code might help: https://github.com/tq-bit/qache/blob/master/src/Cache.ts For 3: Maybe the code of lowdb can point you in the right direction: https://github.com/typicode/lowdb/tree/main/src

https://github.com/typicode/lowdb is a cool option.

I just finished the first stable version of go-store, a lightweight embeeded database written in pure Go. It was heavily inspired by lowdb. The motivation was that I needed something simple to store information for another project and that I wanted to try out Go's generics.

By default, requests are stored locally in a JSON file with the help of LowDB.

Another thing you might consider is literally using the filesystem as a database. There are plenty of vanillla ways to simply read/write to JSON or you could even use a JSON based db github.com/typicode/lowdb again you don't need to think about it as a db your just handling JS objects.

I did want something performant so that I would (hopefully) not run into issues when there are around 100-ish clients connected at the same time. I looked at low-db for a while but did not like that it would JSON.stringify my whole database on every change, which could become a problem when it becomes to big.
