yaml VS nanoid

This makes me happy. I've just done a review of yaml parsers available from Ruby recently to improve the error reporting. Unfortunately libyaml is just bad there - many indentation issues at the end of the document will report errors in line 2 with a completely lost context. Unfortunately x2, there's no real alternative.

I ended up parsing with libyaml and when something fails, parsing again using node and displaying errors through https://github.com/eemeli/yaml It's terrible but it works better. I hope to be able to use libyaml-safer in the future if it does improve on errors.

src: Similar to lib, the src folder is also used to organize code, allowing for easy access to the main codebase. Example from yaml.

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.
