Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

PHP in 2023 - stitcher.io
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.

Is it possible that PHP will ever get async/await functions?
You can leverage https://github.com/amphp/parallel or https://github.com/spatie/async without changing the app much.

Handling big API request (2.5gb) without timeout
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

I Avoid Async/Await
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)

Speeding up SSL checking process
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.

Avoid the Promise.all pitfall
Well you could just install the async package which has lots of useful functions like mapLimit which will reduce the burden and only run a number in parallel.

I Avoid Async/Await
Async/await is certainly not promises. In fact it would be much better implemented without promises as I proposed here: https://es.discourse.group/t/callback-based-simplified-async...
I would even say that async/await is anti-promise, it takes the main functionality of promises, a caching layer for results and errors that allows you to add the code continuation later and elsewhere (which is a major footgun imo) and coerces the execution flow back to going on the next line and provided immediately at compile time which results in a cleaner flow but not as clean, stateless, efficient or functional as if you were to remove the promises completely. Having an additional caching layer and state machine around every asynchronous function call is quite inefficient.
The essence of async/await is not promises, it's the underlying javascript generator (https://developer.mozilla.org/en-US/docs/Web/JavaScript/Refe...) functionality combined with asynchronous code to stop and start the generator. It's the ability to pause and resume function execution based on asynchronous operations.
The promise functionality, the caching layer and state machine for results is basically sanitized away with async/await, it becomes dead-weight computation. The only benefit of promises in async/await code is being able to more easily interface with other promise laden code which you don't need once you have async/await and a library like https://www.npmjs.com/package/async for more complex cases.
Note that promises based async/await is also a mess of an implementation that breaks stack traces and needs to support tons of odd statement corner cases (basically anything that can return an object that could be a promise) whereas a continuation passing style async/await would be a much simpler implementation that would only apply to function calls and maintain stack traces. We get that stack trace support automatically because of the great work of whoever implemented javascript generators which seem to already carry stack traces across paused/resumed functions (if you don't wrap in promises).

What is the difference between async.waterfall and async.series
The nodejs async module: https://github.com/caolan/async provides 2 similar methods, async.waterfall and async.series.

Some questions about events and promises
I don't understand. Sure you could spawn a ton of processes, but things might be bogged down. There are utilities out there for doing work queues.... so only N workers are running at any one time. The async library has some utilities for that. https://github.com/caolan/async

Caolan Asyncjs vs Async/Await: Which One to Use for Async Operations in NodeJS
The documentation of asyncjs is quite straightforward and easy to read. As we've only seen a couple of use cases in this article, I'd recommend to go the asyncjs documentation and check out other possibilities with the library. You can also try to replicate the same using async/await to solidify your understanding of where the library might still make sense.

[AskJS] How were asynchronous functions written before Promises?
It basically was tons and tons of callbacks. They'd nest weirdly deep and be a pain to work with. If you're curious, here's a link to one of my favorite JavaScript libraries from those days - it gave you a bunch of neat utilities for dealing with async code.

Aren't promises just callbacks?
api(function(result){ api2(function(result2){ api3(function(result3){ // do work }); });}); Which I could use a library like async for anyway, with something like:
