In a new article on his blog, Christoph Rumpel shows how you can easily set up a Facebook Messenger chatbot using the shiny new v2 of Botman Studio. Very cool stuff.
Although it seems quite easy to setup BotMan Studio and Facebook you still need to be aware of a few concepts regarding Facebook. I hope I could provide them there and this article helps you to setup your next Facebook Messenger chatbots. From here you are ready to build more and more features to your bot your own. So make sure to checkout the BotMan documentation to get a feeling of what is possible and learn new stuff.

Jeff Madsen wrote down a good piece that explains how mutable Carbon dates can lead to some nasty bugs. I would't mind if Chronos were to be promoted to the default datetime library in Laravel.
If you hang out on any sort of programming forums you have no doubt encountered “The Great Mutable vs. Immutable Debate”. While I’m sure you know what the words mean, if you are new to programming or don’t have a strong Computer Science background it might not be obvious to you whether this is an important concept to be concerned with, or just more “architecture astronaut” purists arguing some obscure fine point.To help you answer that for yourselves, I’m going to show you the difference between the two using two popular Php DateTime libraries — Carbon and Chronos, and then demonstrate the danger of using the mutable one of those.

laravel-medialibrary is probably one of our most powerful packages. It can associate files with Eloquent models. It can also generate derived images such as thumbnails. It has a very developer-friendly API to work with. Here's a quick example:…
At Spatie we've released a plethora of Laravel packages. Now that Laravel 5.5 has been released most of our packages will get a new (major) version. In this blogpost I'd like to explain how we handle new releases of the framework and what it means for our packages. Preparing for release Laravel has…
Jeff Ochoa wrote a nice walkthrough of one of Laravels lesser known functionalities: pipelines.
Basically, using laravel pipelines you can pass an object between several classes in a fluid way to perform any type of task and finally return the resulting value once all the “tasks” have been executed.

Here's a great story by Collin O'Dell, maintainer of league/commonmark amongst other things, on how he was able to extract the class definitions out of obfuscated PHP source files.
Per the framework's license, decrypting the IonCube-protected code was not allowed. This meant it was impossible to recover the original source code. However, I could require those files and execute them in PHP, which would cause those classes to become usable in code. So how does one figure out what code just got loaded & executed?

At Spatie, we're building a multi-tenant app. Seb figured out a great way to handle theme based views.
Laravel allows you register a view vendor namespace which points to a specific directory containing Blade files. This feature is intended for package development, but it's a perfect solution to our problem.By registering a namespace with the current theme's location, we can drop all the dynamic parts of our view names when we're calling them.

? Dedicated view objects are a great use case for Laravel 5.5's new `Responsable` interface.

At Spatie we recently launched a new site: guidelines.spatie.be. It contains articles on how we go about setting things up at Spatie and a collection of styleguides. The source code of the site is available on GitHub. In this blogpost I'd like to share why and how we created our guidelines site. Why…
Ross Tuck is probably one of my favourite bloggers. He doesn't publish something often (his previous post is from 2015), but when he does it's very much worth your time.
The important takeaway here isn’t “value objects, yay, inline juggling, boo!” It’s that we were able to remove several classes of errors by reducing the precision of the DateTime we were handling. If we hadn’t done that, the value object would still be handling all of these edges cases and probably failing at some of them too.Reducing the quality of data to get a correct answer might seem counter-intuitive but it’s actually a more realistic view of the system we’re trying to model. Our computers might run in picoseconds but our business (probably) doesn’t. Plus, the computer is probably lying anyways.

Logan Henson, a developer at Tighten, wrote a new post on the company blog about MySQL's cool ST_Distance_Sphere function.
On a client project recently, we had to make it easy to filter database query results based on the distance between a user and an entity in our database. It's easy to get overwhelmed in that context, worrying about the crazy amount of PHP calculations you're going to have to run. ... If you need to calculate this, you can actually get surprisingly far by just using MySQL!

Grégoire Paris wrote down his opinion on why he dislikes Yoda conditions.
So how do Yoda conditions work? Well it is basically a knee-jerk reaction you have to develop: whenever you write a condition, put the operand that cannot be assigned on the left. This should give you an error message if you make an assignment when you actually meant to make a comparison.
https://dev.to/greg0ire/why-using-yoda-conditions-you-should-probably-not
Personally, I'm not a big fan of Yoda conditions either. My feeling is the the cost of decreased readability is just too high for the small value that Yoda conditions bring to the table.
At this year's Laracon US Adam Wathan gave a talk titled "Cruddy By Design" on how to structure your controllers better. After the conference he published a new GitHub repo that contains the demo app he refactored on stage. The 4 main tips to improve your code come as PRs on the repo with a full description on why the change is valuable. Very cool stuff.
Using this convention as a "rule" is a good way to force yourself to keep your controllers from becoming bloated, and can often lead to learning interesting new things about your domain.For the presentation, I put together a demo app called "CastHacker" that showcases podcasts about software development. It's not a "real" app by any means (lots of imaginary features, no tests, etc.); it's just enough code to demonstrate the concepts from the presentation. Feel free to clone it and play with it locally if you like though.
I've written up each refactoring I shared in the presentation as a detailed pull request.
While working on one of our projects my colleague Sebastian had to create a pdf with some text and charts. In a new post on his blog he explains how he leveraged headless Chrome to create the pdf.
In the JavaScript world Jest, built by Facebook, is an excellent tool to run tests. Not only can it automatically rerun your tests when source code changes, but there's also an interactive mode where you can set a filter on which tests to run while the tool is running. Would it be great if we could…
Christoper Pitt published another excellent piece over at Sitepoint. This time he describes how he built a watcher to automatically recompile his preprocessed code and rerun the tests.
In order to reduce the burden of invoking the transformation scripts, boilerplate projects have started to include scripts to automatically watch for file changes; and thereafter invoke these scripts.These projects I’ve worked on have used a similar approach to re-run unit tests. When I change the JavaScript files, these files are transformed and the unit tests are re-run. This way, I can immediately see if I’ve broken anything.

Laravel Horizon is a kickass dashboard for viewing queued jobs. Co-creator Mohammed Said published two posts about the inner working of the tool. The first one on the Diving Laravel site highlights the overall configuration and how the master supervisor works.
Laravel Horizon is a queue manager that gives you full control over your queues, it provides means to configure how your jobs are processed, generate analytics, and perform different queue-related tasks from within a nice dashboard.In this dive we're going to learn how Horizon boots up and handles processing jobs using different workers as well as how it collects useful metrics for you to have the full picture of how your application dispatches and runs jobs.
https://divinglaravel.com/horizon/before-the-dive
The second one, published on his own blog, shows how queued jobs can get tagged.
Laravel Horizon is shipped with many amazing features that help you understand what goes on with your queue workers, my personal favorite feature is the ability to tag jobs for further investigation.
