WEBVTT NOTE Created by CaptionSync from Automatic Sync Technologies www.automaticsync.com 00:00:00.056 --> 00:00:03.796 align:middle Hey friends! 00:00:04.066 --> 00:00:07.376 align:middle And welcome to the world of Symfony 5... 00:00:07.676 --> 00:00:10.916 align:middle which just happens to be my favorite world! 00:00:11.646 --> 00:00:15.036 align:middle Ok, maybe Disney World is my favorite world... 00:00:15.426 --> 00:00:18.246 align:middle but programming in Symfony 5 is a close second. 00:00:18.666 --> 00:00:23.646 align:middle Symfony 5 is lean and mean: it's lightning fast, starts tiny, 00:00:24.036 --> 00:00:27.016 align:middle but grows with you as your app gets bigger. 00:00:27.516 --> 00:00:29.516 align:middle And that's not marketing jargon! 00:00:29.926 --> 00:00:34.736 align:middle Your Symfony app will literally grow as you need more features. 00:00:35.066 --> 00:00:37.026 align:middle But more on that later. 00:00:37.736 --> 00:00:43.566 align:middle Symfony 5 is also the product of years of work on developer experience. 00:00:44.266 --> 00:00:52.026 align:middle Basically, the people behind Symfony want you to love using it but without sacrificing quality. 00:00:52.826 --> 00:00:58.436 align:middle Yep, you get to write code that you're proud of, love the process, and build things quickly. 00:00:59.136 --> 00:01:04.456 align:middle Symfony is also the fastest major PHP framework, which is no surprise: - 00:01:04.886 --> 00:01:09.236 align:middle its creator also created the PHP profiling system Blackfire. 00:01:09.726 --> 00:01:12.376 align:middle So... performance is always a focus. 00:01:13.216 --> 00:01:14.596 align:middle So... let's do this! 00:01:15.136 --> 00:01:18.576 align:middle Start off by going to http://symfony.com and clicking "Download". 00:01:19.326 --> 00:01:22.806 align:middle What we're about to download is not actually Symfony. 00:01:23.416 --> 00:01:28.176 align:middle It's an executable tool that will help make local development with Symfony... 00:01:28.486 --> 00:01:29.706 align:middle well.. awesome. 00:01:30.776 --> 00:01:33.826 align:middle Because I'm on a Mac, I'll copy this command 00:01:33.826 --> 00:01:37.946 align:middle and then go open a terminal - I already have one waiting. 00:01:38.996 --> 00:01:41.996 align:middle It doesn't matter where on your filesystem you run this. 00:01:42.756 --> 00:01:50.616 align:middle Paste! This downloads a single executable file and, for me, puts it into my home directory. 00:01:51.506 --> 00:01:55.816 align:middle To make it so that I can run this executable from anywhere on my system, 00:01:56.256 --> 00:02:01.636 align:middle I'll follow the command's advice and move the file somewhere else: Ok, try it! 00:02:01.936 --> 00:02:05.666 align:middle symfony It's alive! 00:02:06.316 --> 00:02:11.626 align:middle Say hello to the Symfony CLI: a command-line tool that will help us 00:02:11.626 --> 00:02:15.856 align:middle with various things along our path to programming glory. 00:02:16.866 --> 00:02:21.406 align:middle Its first job will be to help us create a new Symfony 5 project. 00:02:21.856 --> 00:02:25.686 align:middle Run: symfony new cauldron_overflow 00:02:26.686 --> 00:02:31.656 align:middle Where cauldron_overflow will be the directory that the new app will live in. 00:02:32.216 --> 00:02:35.196 align:middle This also happens to be the name of the site we're building... 00:02:35.416 --> 00:02:37.136 align:middle but more on that later. 00:02:37.576 --> 00:02:41.176 align:middle Behind the scenes, this command isn't doing anything special: 00:02:41.616 --> 00:02:47.536 align:middle it clones a Git repository called symfony/skeleton and then uses Composer 00:02:47.586 --> 00:02:49.916 align:middle to install that project's dependencies. 00:02:50.386 --> 00:02:54.156 align:middle We'll talk more about that repository and Composer a bit later. 00:02:55.186 --> 00:02:59.896 align:middle When it's done, move into the new directory: cd cauldron_overflow 00:03:00.896 --> 00:03:04.056 align:middle And then open this directory in your favorite editor. 00:03:04.936 --> 00:03:11.796 align:middle I already have it open in my favorite: PhpStorm, which I did by going to File -> Open Directory 00:03:12.026 --> 00:03:13.966 align:middle and selecting the new project folder. 00:03:15.006 --> 00:03:22.346 align:middle Anyways, say hello to your brand new, shiny, full-of-potential new Symfony 5 project. 00:03:22.906 --> 00:03:27.526 align:middle Before we start hacking away at things, let's create a new git repository and commit. 00:03:28.126 --> 00:03:29.136 align:middle But wait... 00:03:29.476 --> 00:03:34.276 align:middle run: git status On branch master, nothing to commit. 00:03:35.076 --> 00:03:40.706 align:middle Surprise! The symfony new command already initialized a git repository 00:03:40.966 --> 00:03:43.166 align:middle for us and made the first commit. 00:03:43.406 --> 00:03:48.866 align:middle You can see it by running: git log Add initial set of files Nice! 00:03:49.126 --> 00:03:54.896 align:middle Though, I personally would have liked a slightly more epic first commit message... 00:03:55.026 --> 00:03:56.196 align:middle but that's fine. 00:03:56.706 --> 00:03:58.636 align:middle I'll hit "q" to exit this mode. 00:03:59.486 --> 00:04:02.426 align:middle I mentioned earlier that Symfony starts small. 00:04:02.936 --> 00:04:07.186 align:middle To prove it, we can see a list of all the files that were committed 00:04:07.386 --> 00:04:12.146 align:middle by running: git show -- name-only Yea... 00:04:12.486 --> 00:04:13.796 align:middle that's it! 00:04:13.796 --> 00:04:21.346 align:middle Our project - which is fully set up and ready to leverage Symfony - is less than 15 files... 00:04:21.806 --> 00:04:24.046 align:middle if you don't count things like .gitignore. 00:04:24.596 --> 00:04:25.946 align:middle Lean and mean. 00:04:26.596 --> 00:04:30.356 align:middle Let's hook up a web server to our app and see it in action! 00:04:30.356 --> 00:04:35.136 align:middle First, make sure your computer has everything Symfony needs by running: 00:04:35.396 --> 00:04:40.056 align:middle symfony check:req For check requirements. 00:04:40.806 --> 00:04:45.856 align:middle We're good - but if you have any issues and need help fixing them, let us know in the comments. 00:04:46.456 --> 00:04:50.146 align:middle To actually get the project running, look back in PhpStorm. 00:04:50.846 --> 00:04:53.316 align:middle We're going to talk more about each directory soon. 00:04:53.826 --> 00:04:59.886 align:middle But the first thing you need to know is that the public/ directory is the "document root". 00:05:00.376 --> 00:05:03.176 align:middle This means that you need to point your web server - 00:05:03.456 --> 00:05:06.626 align:middle like Apache or Nginx - at this directory. 00:05:07.156 --> 00:05:09.066 align:middle Symfony has docs on how to do that. 00:05:09.766 --> 00:05:15.386 align:middle But! To keep life simple, instead of setting up a real server on our local machine, 00:05:15.686 --> 00:05:18.516 align:middle we can use PHP's built-in web server. 00:05:19.036 --> 00:05:29.486 align:middle At the root of your project, run: php -S 127.0.0.1:8000 -t public/ As soon as we do that, 00:05:30.036 --> 00:05:36.356 align:middle we can spin back over to our browser and go to http://localhost:8000 to find... 00:05:36.716 --> 00:05:38.626 align:middle Welcome to Symfony 5! 00:05:39.126 --> 00:05:40.246 align:middle Ooh, fancy! 00:05:41.606 --> 00:05:45.056 align:middle Next: as easy as it was to run that PHP web server, 00:05:45.456 --> 00:05:49.446 align:middle I'm going to show you an even better option for local development. 00:05:50.266 --> 00:05:56.136 align:middle Then we'll get to know the significance of the directories in our new app and make sure 00:05:56.136 --> 00:05:59.236 align:middle that we have a few plugins installed in PhpStorm... 00:05:59.656 --> 00:06:03.366 align:middle which... make working with Symfony an absolute pleasure.
