Using regular UUIDs stored as a text-based primary key is very slow. Our newly released package spatie/laravel-binary-uuid aims to solve that by binary storing a slightly tweaked version of the UUID. My colleague Brent wrote a blogpost describing how it works behind the scenes. He also included some interesting benchmarks.

The binary encoding of UUIDs solved most of the issue. There's one extra step to take though, which allows MySQL to even better index this field. By switching some of the bits in the UUID, more specifically time related data, we're able to save them in a more ordered way. And it seems that MySQL is especially fond of ordered data when creating indices.

Tim MacDonald, a freelance software developer living in Australia, wrote down how he used our backup package to backup his Laravel and Wordpress sites.

I’m not going to run you through the standard setup or all the great features of the package here, you should definitely get your feet wet and give it a go. You’ll be up and running with backups in no time at all. From here on I’ll assume you’ve had some experience with the package, as to not over explain every step along the way…I do tend to rant off topic otherwise ?

I wanted to have a standardised backup system in place for all my sites. This system would have to include Laravel and WordPress installs - so I tinkered with Spatie’s Laravel Backup package and have managed to get a single install of Laravel to backup all my sites independently, including my WordPress sites ?

The maintainers of Vue.js have recently published their official style guide.

This is the official style guide for Vue-specific code. If you use Vue in a project, it’s a great reference to avoid errors, bikeshedding, and anti-patterns. However, we don’t believe that any style guide is ideal for all teams or projects, so mindful deviations are encouraged based on past experience, the surrounding tech stack, and personal values.

For the most part, we also avoid suggestions about JavaScript or HTML in general. We don’t mind whether you use semicolons or trailing commas. We don’t mind whether your HTML uses single-quotes or double-quotes for attribute values. Some exceptions will exist however, where we’ve found that a particular pattern is helpful in the context of Vue.

https://vuejs.org/v2/style-guide/

Want to see some more style guides? At Spatie we have a guidelines site containing styleguides for Laravel and JavaScript.

This site contains a set of guidelines we use to bring our projects to a good end. We decided to document our workflow because consistency is one of the most valuable traits of maintainable software.

The contents of this site exist for ourselves—more importantly, our future selves—and for giving future collegues a reference to our way of doing things and their quirks. The guidelines cover workflow, code style, and other little things we consider worth documenting.

Sebastian De Deyne, my colleague and all round wizard at Spatie, wrote a new blogpost on how we use Babel.

A lot has been going in in JavaScript the past few years. One of my favorite things has been the usage of babel, which allows us to write future JavaScript syntax today. The babel ecosystem has tons of plugins and configuration options, I'd like to elaborate on our usage at Spatie.

Tinker is probably one of my most used Artisan commands. A minor annoyance is that it can be quite bothersome having to type the fully qualified classname to do something simple.

Today we release a new package called laravel-tinker-tools. When fully installed let's you use the short class names in a tinker session:

This magic does not only work with models but with every class in your Laravel app.

Installing the package

There are a few non standard steps you need to take in order to install the package.

First, pull in the package like you normally would:

composer require spatie/laravel-tinker-tools

Next, create a file named .psysh.php in the root of your Laravel app with this content:

<?php

\Spatie\TinkerTools\ShortClassNames::register();

Finally, dump the optimized version of the autoloader so autoload_classmap.php gets created.

composer dump-autoload -o

And with that all out of the way you can use short class names in your tinker session.

A peek behind the curtains

When you use a class that hasn't been loaded in yet, PHP will call the registered autoloader functions. Such autoloader functions are responsible for loading up the requested class. In a typical project Composer will register an autoloader function that can include the file where the class is stored in.

Composer has a few ways to locate the right files. In most cases it will convert the fully qualified class name to a path. For example, when using a class App\Models\NewsItem Composer will load the file in app/Models/NewsItem.php. It's a bit more complicated behind the scenes but that's the gist of it. To make the process of finding a class fast, Composer caches all the fully qualified classnames and their paths in the generated autoload_classmap.php, which can be found in vendor/composer.

Now, to make this package work, \Spatie\TinkerTools\ShortClassNames will read Composer's autoload_classmap.php and convert the fully qualified class names to short class names. The result is a collection that's being kept in the $classes property

Our class will also register an autoloader. When you use NewsItem in your code. PHP will first call Composer's autoloader. But of course that autoloader can't find the class. So the autoloader from this package comes next. Our autoloader will use the aforementioned $classes collection to find to fully qualified class name. It will then use class_alias to alias NewsItem to App\Models\NewsItem.

What happens if there are multiple classes with same name?

Now you might wonder what'll happen it there are more classes with the same name in different namespaces? E.g. App\Models\NewsItem, Vendor\PackageName\NewsItem. Well, autoload_classmap.php is sorted alphabetically on the fully qualified namespace. So App\Models\NewsItem will be used and not Vendor\PackageName\NewsItem.

Because App starts with an "A" there's a high chance that, in case of a collision, a class inside your application will get picked. Currently there are no ways to alter this. I'd accept PRs that make this behaviour customizable.

Need more tinker magic?

There are a lot of other options that can be set in tinker.config.php. Learn all the options by reading the official psysh configuration documentation. Caleb Porzio's excellent blogpost "Supercharge Your Laravel Tinker Workflow" is an excellent read as well. This package was inspired by that blogpost

Maybe you don't need tinker...

If you want to run a single line of code tinker can be a bit of overkill. You must start up tinker, type the code, press enter, and quit tinker. Our laravel-artisan-dd package contains an Artisan command that can dump anything from the commandline. No need to start and quit tinker anymore.

We've updated the package so you can make use of short class names too. Here's how you can dump a model using a minimal amount of keystrokes:

In closing

laravel-tinker-tools and laravel-artisan-dd aren't the only packages we've made that make developing Laravel apps easier.

Be sure to take a look at these ones at well:

• laravel-tail
• laravel-migrate-fresh
• laravel-db-snapshots
• laravel-mailable-test
• laravel-demo-mode

If you want to know how a visitor got on your site you can check the referer request header. Yeah, it's misspelled. That header contains the url of the previously visited page. Unfortunately browsers will fill that header regardless of the previous url was an internal or external one. So after the first click on an internal link you won't know anymore on which site a visitor was on previously.

Our new laravel-referer package aims to fix that problem. Once the package is installed it will remember the original referer in session. So even after a users clicks around on your site, you are still able to detect which site he or she visited previously.

Because users are also often tracked using UTM Codes the package will also remember the utm_source query parameter.

The easiest way to retrieve the referer is by just resolving it out of the container:

use App\Spatie\Referer\Referer;

$referer = app(Referer::class)->get(); // 'google.com'

Or you could opt to use Laravel's 5.4 fancy new automatic facades:

use Facades\Spatie\Referer\Referer;

$referer = Referer::get(); // 'google.com'

To know more take a look at the readme of the package on GitHub.
