1@bryantebeek Comparing the PHP & Node.js ecosystems 

1@bryantebeek History We switched our technology stack a couple of times and learned a lot in the process 

1@bryantebeek History Stacks before Lifely + Yii v1.1 + Laravel v2 - v4 v5.2 + v5.3 

1@bryantebeek History Stacks at Lifely + Laravel v5 + Symfony v2.8 + v3.4 v5.4 + v7.x 

1@bryantebeek History Stacks at Lifely + + v0.10 

1@bryantebeek History Stacks at Lifely + + + Meteor v1.2 - v1.6 v0.12 - v8.x 

1@bryantebeek History Stacks at Lifely + + v4.x - v10.x 

1@bryantebeek History Stacks at Lifely v0.10 - v10.x v5.2 - v7.2 

1@bryantebeek History But how do they compare? 

1@bryantebeek 

1@bryantebeek Comparing the two Let's take a look at the Node.js and PHP ecosystems 

1@bryantebeek 1. Architecture 

1@bryantebeek Comparing the two Single-threaded (uses an event loop) Non-blocking, asynchronous I/O Bad on CPU intensive tasks (blocking) Runs on the performant and actively updated V8 engine (powers Chrome browser) Process exception, whole application restarts if not handled correctly 1. Architecture 

1@bryantebeek Comparing the two Process pool (FPM) Synchronous I/O Execution failure / crash, much less of a problem Bootstraps whole application on each request (includes DB connection etc.) 1. Architecture 

1@bryantebeek Comparing the two Overview 1. Architecture 

1@bryantebeek 2. Development 

1@bryantebeek Comparing the two Both client and server are written in Javascript, easier to develop full stack (SPA) Need to wait for code to be build on file change No all-in-one frameworks that match the quality of their PHP counterparts Except for the big frameworks, there are a lot of small, actively updated packages 2. Development 

1@bryantebeek Comparing the two A lot of great frameworks like Laravel and Symfony speed up development Easy local development environments (WAMP / LAMP / Laravel Homestead) Instant able to retest application on code change, no need to wait for builds There are a lot of packages that integrate directly with said frameworks, which make installation a breeze 2. Development 

1@bryantebeek Comparing the two 2. Development Amount of packages from modulecounts.com PHP averages at 111/day, Node.js averages at 538/day 

1@bryantebeek Comparing the two Overview 1. Architecture 2. Development 

1@bryantebeek 3. DevOps 

1@bryantebeek Comparing the two Less hosting solutions, needs more custom work to run it in production Requires building the code most of the time (Babel, Typescript) Need to watch the main process and make sure it keeps running at all times Docker helps, or other solutions like Systemd or Supervisor 3. DevOps 

1@bryantebeek Comparing the two Countless of easy hosting solutions online Also means there is a lot of competition, drives down prices Extensions can be a bit of a problem (does your hosting support / include X?) Same holds for upgrading PHP versions 3. DevOps 

1@bryantebeek Comparing the two Overview 1. Architecture 2. Development 3. DevOps 

1@bryantebeek 4. Language 

1@bryantebeek Comparing the two Iterates really fast Javascript a few years ago was worse than PHP Evolved a lot with the recent ECMAScript editions Typescript saves the day. Write fully typed, highly maintainable code (generics, etc.) 4. Language 

1@bryantebeek Comparing the two Iterates slower, so it's easier to keep up PHP has way better support for reflection than Javascript (Laravel dependency injection) Magic methods can be used in creative ways (Laravel "User::where()") Standard lib functions are inconsistent and aren't methods on their respective primitives (e.g. array_* and str* families) Anonymous functions require the `use` statement and have no shorthand notation 4. Language 

1@bryantebeek Comparing the two 4. Language $message = 'Hello'; hello(function ($user) use ($message) { return "$message $user!->firstname"; }); 

1@bryantebeek Comparing the two 4. Language const message = 'Hello World' hello(user !=> "${user.firstname} ${message}") 

1@bryantebeek Comparing the two 4. Language $numbers = [1, 2, 4, 8]; !// 16, 8, 4, 2 implode(', ', array_reverse(array_map(function ($num) { return $num * 2; }, $numbers))); 

1@bryantebeek Comparing the two 4. Language const numbers = [1, 2, 4, 8] !// 16, 8, 4, 2 numbers.map(num !=> num * 2).reverse().join(', ')

1@bryantebeek The two at Lifely So why did we switch to Node.js instead of PHP and why you probably shouldn't do the same? 

1@bryantebeek The two at Lifely Why we made the switch In 2014 Node.js was the all new hype Created bundlin.com in Node.js One of our early customers requested we use Meteor We then used Meteor for one more application Client and server written in the same language MongoDB + NoSQL 

1@bryantebeek The two at Lifely Why you probably shouldn't Performance is more dependent on how well the backend has been written instead of the actual core architecture Node.js is not magically going to make your application fast PHP ecosystem has great frameworks and CMS-like systems Laravel, Symfony, Wordpress, etc. Easy to deploy, focus on the actual application being build 

1@bryantebeek Conclusion We settled with Node.js and our custom 'framework', but PHP would really be a viable option as well 

1@bryantebeek Conclusion Always use the right language for the situation
