zeitwerk VS Rector

To setup it's pretty simple, you just need to create a file inside bin/console and require all the files you want to use on a REPL, most of the times we use gems like zeitwerk to provide the auto requiring, but if you want to do it manually, refer to the example below:

zeitwerk

Zeitwerk takes a directory and makes every file underneath it available to load. The convention is that every new sub-directory is a new module, and every file defines a class with the same name as the file.

There is a gem that does that used by Rails and multiple other gems:

It is pretty easy to set it up in any Ruby project.

I actually prefer auto-loading, which lets you iterate through a package manager much easier/faster - PHP iterated through PSR-0[0] before landing on PSR-4[1], and you can always build your own (which is what most frameworks pre-composer were doing).

With Rails 7 and Zeitwerk, the Ruby community has landed on a very similar auto-loading system as PHP now[2] with constants translating to paths by convention.

If you're working on non-Rails apps and need to deal with loading code, zeitwerk can be used anywhere, unlike the old Rails autoloader. It's also really easy to set up.

Zeitwerk

With a few modifications in the gem source code, we could easily integrate Auth0 into our Rails API, but that on Rails 5. Rails 6 brought Zeitwerk code loader together, which makes it harder to perform the alterations suggested in my previous post.

For the next phase of updates, I installed PHP Rector.

Rector is an excellent tool for refactoring and modernizing code. In our case, we will only use the ExplicitNullableParamTypeRector rule.

As part of the journey to PHP perfection, you should embrace Rector. It's a amazing, free, and open-source tool for migrations, code quality, type coverage, pushing PHPStan to the highest levels, and yes, it can even auto-fix your existing code! It seamlessly integrates into the CI process, making your development workflow smoother than ever.

Rector can help automating some changes.

Yep... Rector

I'd also recommend taking a look at Rector to help automate some of this.
