Event store optimizations in laravel-event-sourcing original

by Freek Van der Herten – 5 minute read

About a year ago, we released laravel-event-projector. It focused on adding projectors, an important concept in event sourcing, to Laravel.

After the release of the package, we continually kept improving it. We added aggregates, a way to test those, a brand new section in the our documentation that explains event sourcing from scratch, and DX improvements all across the board.

We now feel confident that the package is a good starting point for getting started with event sourcing in Laravel. That's why we're renaming the package to laravel-event-sourcing.

– github.com

Unsung Laravel hero Joseph Silber opened up a very interesting PR to Laravel. Let's hope this one gets accepted.

Whereas the existing Collection class wraps a native array, the new LazyCollection class wraps a native iterator, while still providing most of the methods that we know and love from a regular collection.

Mohammed Said shares some solid tips on optimizing costs when working in a serverless environment like Laravel Vapor

Laravel Vapor uses different AWS resources to efficiently get your application up and running in the serverless cloud. The building block of the whole thing is AWS Lambda, it's where the actual computing happens.

Viewing model counts in the Laravel Debugbar

– reinink.ca

Jonathan Reinink has added a very usefull metric to Laravel debugbar

Last week at Laracon US I gave a talk titled Eloquent Performance Patterns. In that talk I used a custom Laravel Debugbar metric I created to track how many Eloquent models were being hydrated throughout a request. I've had a lot of people asking about this, so today I submitted a pull request to the Laravel Debugbar to add this as an official metric.

Your first performance budget with Lighthouse

– bitsofco.de

Ire Aderinokun, Front-End Developer and User Interface Designer, explains how you can Lighthouse in CI.

Until recently, I also hadn't setup an official performance budget and enforced it. This isn’t to say that I never did performance audits. I frequently use tools like PageSpeed Insights and take the feedback to make improvements. But what I had never done was set a list of metrics that I needed the site to meet, and enforce them using some automated tool.

Caching the entire response of a Laravel app original

by Freek Van der Herten – 5 minute read

When a request comes in your app will return a response. To create that response, your application has to do some work. Most likely queries will execute. This all takes some time. Wouldn't it be nice if the same request comes in, we can return the response the application has constructed previously?

Find Segfaults in PHP like a boss

– jolicode.com

Grégoire Pineau explains how you can find the source of a segfault in PHP.

Sometimes, a segfault happens, but you don’t know where, and your PHP installation does not have tools to find it. Or sometime, you think PHP is hanging, but you don’t know where. You may use xdebug, but you don’t want to click so many times on the « next call » button.

How migrations might be slowing down your Laravel tests

– alexvanderbist.com

Having a lot of migrations might slow down your tests. My colleague Alex shares how you can fix this.

One of the larger test suites I run daily has about 1500 tests in it. It takes just over 4 minutes to complete at an average of 160ms per test. That's pretty good. However, lately I've noticed a delay between starting PHPUnit and running the first test. This delay grew to the point where running a single test would take almost 12 seconds with the setUp method using most of that time on... migrations.

Loading Eloquent relationship counts

– timacdonald.me

There are three ways of loading relationships in Laravel. Tim MacDonald, a freelance dev based in Sydney, explains them all.

It is often useful to show the number of related models a given instance has, but not actually need any specific information about the related models, just how many exist. In this scenario you do not want to load all of the related models into memory to count them, we want our database to do the heavy lifting for us. Laravel offers a number of ways to retrieve relationship counts.

Major performance problems when running PhpStorm on a scaled resolution

– stitcher.io

It's very frustrating I can't use a scaled resolution on my Mac because of PhpStorm.

PhpStorm has had performance issues on OSX for a very long time now, sometimes to the point of being unusable. I've written about these issues before, but it's good to keep a regularly updated list of what's going on. So without further ado: if you're on OSX (Sierra, High Sierra or Mojave); if you're experiencing PhpStorm performance issues, this post might help you.
