Asynchronous stack traces: why await beats .then()
On his blog Mathias Bynens explains the differences under the hood between async/await and vanilla promises.
The fundamental difference between await and vanilla promises is that await X() suspends execution of the current function, while promise.then(X) continues execution of the current function after adding the X call to the callback chain. In the context of stack traces, this difference is pretty significant. ... Enable JavaScript engines to handle stack traces in a more performant and memory-efficient manner by following these recommendations:
- Prefer async/await over desugared promises.
- Use babel-preset-env to avoid transpiling async/await unnecessarily. ...

Handling Stripe webhooks in a Laravel application original
In the project I'm currently working on I had to integrate Stripe webhooks. Stripe has great documentation on how to handle webhooks, but it still took a fair amount of time to get the integration just right. My solution for handling webhooks is pretty generic and reusable by others. I decided to…

Essential image optimization
Addy Osmani, a Google Chrome engineer, recently published a e-book on image optimization. You can read it in it's entirety here: https://images.guide/
Images take up massive amounts of internet bandwidth because they often have large file sizes. According to the HTTP Archive, 60% of the data transferred to fetch a web page is images composed of JPEGs, PNGs and GIFs. As of July 2017, images accounted for 1.7MB of the content loaded for the 3.0MB average site.Per Tammy Everts, adding images to a page or making existing images larger have been proven to increase conversion rates. It's unlikely that images will go away and so investing in an efficient compression strategy to minimize bloat becomes important.
If you need to optimize images in your PHP application take a look at our image optimization package. If you're a Laravel user you'll be happy to know that there's also a Laravel version of the optimizer. Our Laravel Medialibrary also comes with built-in support for optimizing images.

Handling Stripe payments in Laravel
Povilas Korop, creator of Laravel Daily and Quick Admin Panel, wrote an extensive guide on how to integrate Stripe into a Laravel application.
Stripe is one of the most popular payment merchants for web, but information about Laravel integration is pretty fragmented, so I decided to write a really long tutorial about this topic.We will cover:
- General logic how Stripe works
- Simple one-time payment integration
- Testing and production environment setup
- Saving transaction data for future reference
- Recurring payments with Laravel Cashier
- Getting invoices data and PDF download

Partitioning for concurrency in synchronous business processes
On his blog Frank De Jonge, member of the PHP League and creator of Flysystem, explains a cool pragmatic solution how to ensure queued processes for the same user complete in the right order.
The use of multiple workers allows for much higher throughput, but it also allows for race conditions during processing. When messages for the same user are sent to different workers, handling order can no longer be guaranteed. Therefore we have failed to fulfil our business rule.If we were able to ensure every message from the same user were sent to the same worker, the worker could ensure those messages are handled in order while the system as a whole would still benefit from the degree of parallelism. But how do we make this happen?

BetterReflection v2 has been released
The awesome Roave team has recently released v2 of their BetterReflection package. It can do anything PHP's native reflection API can, but without actually autoloading the code.
The operational concept is quite simple, really:
- We scan your codebase for files matching the one containing your class. This is fully configurable, but by default we use some ugly autoloader hacks to find the file without wasting disk I/O.
- We feed your PHP file to PHP-Parser
- We analyse the produced AST and wrap it in a matching Roave\BetterReflection\Reflection* class instance, ready for you to consume it.
Read all about it on Marco Pivetta's blog: https://ocramius.github.io/blog/roave-better-reflection-v2.0/
New features in our packages original
Every time our team releases a package I have the habit of writing an introductory blogpost. But after the initial release most pages gain more features through PRs by the community and ourselves. Mostly these new feature go unnoticed. That's why I plan on regularly writings posts on noteworthy…
Building an SMS admin powered by Laravel and Nexmo
JMac, the creator of Laravel Shift, shared how he can very easily spin up a new job on his service by sending a simple SMS message.
In the end, all I need is a quick way to run a Shift on the go. Looking back on almost two years of support, I often have the Shift number readily available. Creating the job and adding it to the queue is at most two lines of code. So the steps are not the pain point.The pain point is connecting to the server. Unless I want to carry my laptop around, I can’t connect to the server to run the Shift. (I actually have taken my laptop with me during peak times.)
What do I carry around with me all the time? My phone. I’m already reviewing the support emails from my phone. Wouldn’t it be great when I need to run a Shift manually to just reply or send a text.

All videos of Laracon EU 2017 have been released
Laracon EU 2017 was, like the previous years, an excellent event. Together with 700+ fellow artisans I very much enjoyed watching the talks and meeting people between them. All video's of this edition have recently been made available on YouTube. Here's a handy playlist that contains them all.
I had the honor of speaking at the event as well, here's the video of my talk:
Goodbye controllers, hello request handlers
Jens Segers, developer at Teamleader and author of the popular Optimus and laravel-mongodb packages, wrote about an alternative to controllers.
Let me introduce you to request handlers. The concept is very simple, yet very unknown to a lot of PHP developers. A request handler is basically a controller, but limited to one single action. This concept is very similar to the Action-Domain-Responder pattern which was proposed by Paul M. Jones, an alternative for the MVC pattern that focuses on a more clear request to response flow for web applications.

iTerm2 leaks everything you hover in your terminal via DNS requests
iTerm2, a populair terminal app, contained a very bad security issue. Everything you hover over was being checked if it was a clickable url. To determine if it's a valid url, the hovered over string was being checked against DNS server. So if you hover over a password, or a secret key or whatever it sent out to the internet. Obviously this is a big problem. It's fixed in the latest version. So if you use iTerm2 and haven't updated it recently, be sure to do it now! The problem is fixed in version 3.1.1.
iTerm2's leak issue was first discovered ten months ago. iTerm2's creator initially reacted by adding an option to iTerm 3.0.13 that allowed users to disable DNS lookups. The feature remained turned on by default for new and existing installations.Dutch developer Peter van Dijk, software engineer for PowerDNS, a supplier of open-source DNS software and DNS management service, re-reported this feature and this time around, he pointed out some of the severe privacy leaks not included in the first bug report.
"iTerm sent various things (including passwords) in plain text to my ISP's DNS server," van Dijk wrote flabbergasted in a bug report he filed earlier today.
This time around, George Nachman, iTerm2's maintainer, understood the severity of the issue right away and released iTerm2 3.1.1 to fix the problem within hours. He also apologized for enabling this feature by default without analyzing possible consequences in more depth.
Event Sourcing: what it is and why it's awesome
If you haven't heard about event sourcing or are unsure about what it is, Barry O Sullivan has got you covered. Recently he wrote up a blogpost that explains it very clearly.
Event Sourcing (ES) is opposite of this. Instead of focussing on current state, you focus on the changes that have occurred over time. It is the practice of modelling your system as a sequence of events. ... It solves all the big problems our team has faced when building large scale distributed business software. It allows us to talk to the business in their language, and it gives us the freedom to change and adapt the system with ease.
