Lowdb VS nanoid

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.

https://jsondb.io/ or https://github.com/typicode/lowdb

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.

Last thing left is to use our new upload function in our server action. Since I like to upload images in single format and have some more control over them, I will additionally use sharp library. For file name, I'll generate some random string using nanoid:

Our API is in node. And God, how I suffered to import nanoid in an esmodule project. I had to vendor it, since using a previous version was not ideal. With bun, we can no longer worry about that. Just import what you need and done.

No thread about UUID is complete without a plug for NanoID! https://github.com/ai/nanoid/blob/main/README.md

Generate a unique file name using the nanoid library.

The syntax should read similar to SQL itself. We’re using a Python port of nanoid to generate our IDs. There’s only one thing missing… how do we actually create the table?

I usually go for Nano Id for new projects https://github.com/ai/nanoid

Nano ID

In another comment I mentioned I use nanoid in my projects now. It has a default space of 64^21 and has an a page where you can play with key lengths and alphabet sizes and see the probability of collisions :

At the default 64 character alphabet with a 21 character key length it would take ~41 million years in order to have a 1% probability of at least one collision if you generated 1000 ids per second.

Using randomly generated IDs like Nano ID could be a good alternative, however, as a developer, we must understand what Nano ID really does in our application. Defining the number of characters in the generated IDs is also important, to help with that Nano ID has a Collision Calculator to give us how many years in order to have a 1% probability of collision.
