This is a little something I've been working on for the past week. It's called Magic Test and I'm very excited!
Imagine if instead of manually writing your browser tests, you could simply click around and have a test generated for you?

Scaling Laravel to 100M+ jobs and 30,000 reqs/smin(pre-Octane)
If you prefer to read this as a blog post:

already wrote a very interesting blog on how Fathom Analytics scaled Laravel, but my story is about different.

I compiled a list of good videos/posts for Laravel and PHP developers. It's not completed but I'll add new tweets later.
If you're working with Laravel and PHP, check this out — you might know some stuff already but I'm sure there are new things to learn here. Thread 👉

I love Laravel query scopes, but there are a few drawbacks:
- You lose autocomplete/context
- Things start to get confusing when you have a lot of them
Here's how you can swap them with custom query builders:

Given you have a:
- very legacy PHP project
- mixed html/php files
- lots of mysql_query calls throughout the app
- no tests
what is the best way to introduce modern practices, separate the views from the backend code and introduce an ORM without breaking what already exists?

Modular Laravel
A modular monolith offers a fantastic middle-ground between the simplicity of a traditional monolithic architecture, and some of the benefits you might encounter when using micro-services.

Let’s see how the service container works!
The container’s job is to give you objects. When you request an object, it might do that in 2 ways (in Laravel, specifically): either by checking if what you requested is bound already, or by instantiating it.

I'm not too fond of repositories in Laravel as a decoupling mechanism, but I like them to centralize data retrieval. A cool thing is that you can still combine them with query scopes to get very readable methods.

I hate searching for flights, so I decided to build my own CLI script 🤓.
You give it the details, airline & an offset, and it'll fetch the cheapest 3 flights for each day in the period, in $ and air miles.
Next step is comparing all airlines & multiple destinations!

One of the benefits of having proper data ownership between modules is that you get full autonomy.
The "Learning" module owns all of its data... in turn, we get a much smaller, concise API.
For example, instead of relating to a "global" User model, it relates to a much…

One of the best things I've learned about software arch is being aware of and designating boundaries in software.
Boundaries are hard to think of because they're so abstract; you don't have something you can physically see.

Whenever introducing automated tests to an existing codebase, I always like to start with "cheap, valuable tests".
What I mean with this is: tests that are quick to be written, run fast, and provide lots of values in the long run. This one, for example 👇🏻

If I had to suggest one improvement you could make for maintainability I'd say use objects over arrays (hashmaps) in PHP.
Arrays are untyped and you just have no idea about what is there. You can use array shapes and static analysis but IMO it's still not good enough.

TDD is super powerful for stuff like this — I wrote 3 tests, one for each type of transaction, with the API I'd _like_ to have, and only after the tests I started writing the implementation.
I don't do things like this all the time, but it really helps you think through things.

I love Eloquent and something I missed was being able to persist an entire object graph, with its relations, in one go, so I made a package that does that:
It's still a beta version and I just pulled what I had done in a PR to the core, so be careful!

I'm finding it very pleasant to use Eloquent this way.
I get all the benefits of Active Record, and also some things I enjoy in repository-based approaches.
These methods don't persist anything. They build the full object graph, and everything is saved in one go. 🔥

We often use queues simply as a way to deliver a response to the client faster, but there are much more benefits.
To me, one of the most important benefits is that horizontal scaling becomes so much easier — adding more servers (+ workers) = more firepower.

One of the best ways to understand the internals of frameworks is to build simple versions of their components.
For example, building a router based on the Symfony router or a Container based on Laravel’s Container.

One thing I really enjoy about not grouping things by type is that naming and figuring out where things to go stop being a problem.
"Does that go into Services? Data? Actions?" is not a thing. The context is enough.
Not for everyone, but I love it 🥂

A very common problem I see in *tons* of applications is not performing state change as a unit of work.
It's important to ensure you don't have inconsistent data.
In many cases, it simply means wrapping persistence within a database transaction.
