zap-db VS Lowdb

An easy to use JSON database written with ease of setup and memory management of slack bots in mind.

You should consider avoiding sync FS operations however, such as in https://github.com/sdslabs/zap-db/blob/master/src/lib/session.ts . This is because of how the event loop in Node.js works: using async operations allows Node.js to work on another request while it waits for the operating system to read the file; if you use sync operations, however, it blocks the entire event loop so only one request at a time can be processed.

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.

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

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.
