TailwindCSS Tips

I've been dabbling in CSS my entire career. In the early days, it was relatively simple, as our browsers were fairly limited. But over the years, CSS has become more and more capable, allowing styles to target only tags with specific tag attributes, only apply at specific screen sizes, and even perform complex layouts using things like flexbox and grid. I take a bit of time every now and then to understand these things... but since I don't use CSS a ton, it's hard to keep up.

As such, over the past decade, I've tended to use CSS frameworks, and generally Bootstrap. Every couple years, a new major version is dropped, and I have to learn new structures and components, and struggle to get things to look the way I want. Worse, when I use these frameworks, injecting custom CSS often means understanding how the framework is already styling components so I can ensure things don't conflict.

The last couple years, I've been keeping an eye on TailwindCSS. I've been a bit skeptical, as its declarative, utility-first approach looks a lot like doing CSS inside your HTML, which, honestly, feels off. I've typically subscribed to the idea of semantic HTML, which advocates separating style from markup. Having styles directly that mimic CSS directives associated with every tag feels like an unholy mix, and a far cry from semantic HTML.

And then there's the hype. The original author and project lead of Tailwind is a huge hype man, and hype tends to turn me off. That's on me, not them, but having been in the business for over two decades, I'm finding I'm more and more likely to discount hyped products and projects, because I've seen them come and go so frequently; there's often an indirect relationship between the amount of hype and the long-term viability of a project. I've also often observed that hype serves as a way for users to deflect reasonable critique, and the more vehement the user base, the less interested I am in engaging with them because of this. Clearly, YMMV, but it was definitely something keeping me from really investigating Tailwind.

However, recently, in helping out the PHP Foundation, I volunteered to setup their static website, and the team requested using TailwindCSS, so I dove in.

And I discovered... I kind of love it.

This is one of those "I'll be googling this in the future" posts.

Getting OpenSwoole and the AWS SDK to Play Nice

I have some content that I store in S3-compatible object storage, and wanted to be able to (a) push to that storage, and (b) serve items from that storage.

Easey-peasey: use the Flysystem AWS S3 adapter, point it to my storage, and be done!

Except for one monkey wrench: I'm using OpenSwoole.

Exposing webhooks via mezzio-swoole

I was first introduced to the concept of webhooks via a 2009 blog post by John Herren, a former colleague at Zend. At the time, they were in their infancy; today, they're ubiquituous, as they provide a mechanism for a service to notify interested parties of events. This saves traffic; instead of consumers polling an API for event changes, the service notifies them directly. It also means that the consumer does not need to setup things like cronjobs; they instead setup a webhook endpoint, register it with the service provider, and their application takes care of the rest.

The thing is, handling a webhook can often lead to additional processing, and you are expected to send an immediate response to the provider indicating you received the event.

How can you achieve this?

Running cronjobs via an Openswoole timer

Sites I build often utilize cronjobs to periodically pull in data from other sources. For example, I might want to poll an API once a day, or scrape content from another website once a month. Cronjobs are a perfect fit for this.

However, cron has a few problems:

  • If the job is writing information into the file tree of your web application, you need to ensure permissions are correct, both at the filesystem level, and when writing the cronjob (e.g., running it as the same user, or changing permissions on completion).
  • If you are running console tooling associated with your PHP application, you may need to worry about whether or not particular environment variables are in scope when you run the job.
  • In containerized environments, usage of cron is strongly discouraged, as it means running another daemon. You can get around this with tools such as the s6-overlay, but it's another vector for issues.

Since most sites I build anymore use mezzio-swoole, I started wondering if I might be able to handle these jobs another way.

Caddy as a Secure Reverse Proxy

I've been using Caddy as a front-end reverse proxy for several years now, on the advice of Marco Pivetta. Somewhere along the line version 2 was released, and I updated at some point, but evidently didn't quite understand some of its configuration options, particularly around HSTS support and providing your proxied application information about how the client tried to connect.

Tinker-like REPL for Mezzio

Today in the Laminas Slack, somebody asked if there was an equivalent to Laravel's Tinker REPL. The short answer is "no", but I had a suggestion for them.

Laminas CI Automation

The Laminas Project has close to 200 repositories between the main project, Laminas API Tools, and Mezzio. It's a lot to maintain, and keeping on top of incoming patches can be a gargantuan task, much less creating releases.

That's why this past year, we've spent a bunch of time on streamlining our processes; we want to be able to review, merge, and release changes quickly and confidently. To that end, we have developed a number of GitHub Actions to make these processes as easy as possible for our maintainers.

Development-Mode Modules for Mezzio

I fielded a question in the Laminas Slack yesterday that I realized should likely be a blog post. The question was:

Is there a way to register development-mode-only modules in Mezzio?

There's actually multiple ways to do it, though one that is probably more preferable to others.

More Changes Coming for the Laminas Project

Progress has been happening at a furious pace on the Zend Framework to Laminas transition, with major changes still dropping even now.

Most recently, we decided to rename the subprojects. Apigility will become the Laminas API Tools, and Expressive will become Mezzio.

For more background, read the Zend by Perforce blog post.
