Theme-based views in Laravel using vendor namespaces

I’m building a multi-tenant Laravel application. One of the requirements of the project is that every client can have their own theme based on their corporate guidelines. By default a few css adjustments will suffice, but some clients request a completely different template.

Conditionally loading a different stylesheet per client is pretty trivial, but in order to use a completely different view per theme you quickly end up typing the same thing over and over across various parts of your application.

Is snapshot testing viable in PHP?

Christopher Pitt wrote a pretty comprehensive article on one of our latest packages, which is one of my favorite packages I’ve written at Spatie to date, phpunit-snapshot-assertions.

Ah-ha moments are beautiful and rare in programming. Every so often, we’re fortunate enough to discover some trick or facet of a system that forever changes how we think of it. For me, that’s what snapshot testing is.

The list function & practical uses of array destructuring in PHP

PHP 7.1 introduced a new syntax for the list() function. I’ve never really seen too much list() calls in the wild, but it enables you to write some pretty neat stuff.

This post is a primer of list() and it’s PHP 7.1 short notation, and an overview of some use cases I’ve been applying them to.

A package for snapshot testing in PHPUnit

The gist of snapshot testing is asserting that a set of data hasn’t changed compared to a previous version, which is a snapshot of the data, to prevent regressions. The difference between a classic and an is that you don’t write the expectation yourself when snapshot testing.

When a snapshot assertion happens for the first time, it creates a snapshot file with the actual output, and marks the test as incomplete. Every subsequent run will compare the output with the existing snapshot file to check for regressions.

Snapshot testing is most useful larger datasets that can change over time, like serializing an object for an XML export or a JSON API endpoint.

Non-breaking, SEO friendly urls in Laravel

When admins create or update a news item—or any other entity—in our homegrown CMS, a url slug is generated based on it’s title. The downside here is that when the title changes, the old url would break. If we wouldn’t regenerate the url on updates, edited titles would still have an old slug in the url, which isn’t an ideal situation either.

Our solution: add a unique identifier to the url that will never change, while keeping the slug intact. This creates links that are both readable and unbreakable.

Using a database for localization in Laravel

When building a website for a client that wants to be able to manage content, Laravel’s language files aren’t ideal since you can’t edit them without diving into a bundle of text files. We recently decided to drop all the lang files in our custom CMS in favor of persisting translations in the database, which allows us to build a custom interface for managing them.

This post is a quick overview on overwriting Laravel’s default translation loader, which means you can keep using the lang method while fetching the translations from a database. Writing a custom loader is easier than it sounds. First we’ll set up our translation models, then we’ll write our loader, and finally register it in our application.

Normalize your values on input

Dynamic languages allow us to pass anything as a parameter without requiring a specific type. In turn, this means we often need to handle some extra validation for the data that comes in to our objects.

This is a lightweight post on handling your incoming values effectively by normalizing them as soon as possible. It’s a simple guideline worth keeping in mind which will help you keep your code easier to reason about.
