boxed VS async

I was happy when Promise became available, but in retrospect I'd wish we would have skipped ahead and gotten Observable (e.g: https://rxjs.dev/) instead to enable more powerful functionality and composition etc.

In Typescript dealing with rejection is also painful since rejection reasons can't be guaranteed to be Error even when you always take care of that. And it can't help you guarantee that you're handling all types of errors thrown. For that purpose I'm thinking of using https://github.com/supermacro/neverthrow#readme or https://swan-io.github.io/boxed.

Agree that try/catch is verbose and not terribly ergonomic, but my solution has been to treat errors as values rather than exceptions, by default. It's much less painful to achieve this if you use a library with an implementation of a Result type, which I admin is a bit of a painful workaround, but worth it. I've recently been using: https://github.com/swan-io/boxed.

By far the greatest benefit is being able to sanely implement a type-safe API. To me, it is utter madness throwing custom extensions of the Error class arbitrarily deep in the call-stack, and then having a catch handler somewhere up the top hoping that each error case is matched and correctly translated to the intended http response (at least this seems to be a common alternative).

I really wanna get into writing more asynchronous PHP but having to switch to a whole different web server and execution mode is a major stumbling block. The only library (that I know of) that allows asynchronous code in traditional PHP environment is this one by Spatie.

You can leverage https://github.com/amphp/parallel or https://github.com/spatie/async without changing the app much.

To handle this problem i've used "https://github.com/halaxa/json-machine" to decrease the memory usage and "https://github.com/spatie/async" to decrease the take taken for the "update process" to complete

It drove me crazy too, until I needed to use Puppeteer which requires you to write async/await (there are Puppeteer implementations in other languages, but they all seem to make compromises I didn't want). Generally speaking, async/await allows you to write code that looks and feels serial. Perhaps try using one of the async libraries for PHP to wrap your mind around the concept of async/await (like https://github.com/spatie/async)

Try using spatie's async package and run a chunk of 10 tests in each batch, if that works it might cut your waiting time by quite a lot.
