Scroll down to the script below, click on any sentence (including terminal blocks!) to jump to that spot in the video!
Hey guys! Yes! It's Symfony 4 time! I am so excited. Why? Because nothing makes me happier than sitting down to work inside a framework where coding is actually fun, and where I can build features fast, but without sacrificing quality. Well, maybe I'd be even happier doing all of that on a beach... with, maybe a cold drink?
Anyways, Symfony 4 completely re-imagined the developer experience: you're going to create better features, faster than ever. And, Symfony has a new, unique super-power: it starts as a microframework, then automatically scales in size as your project grows. How? Stay tuned...
Oh, and did I mention that Symfony 4 is the fastest version ever? And the fastest PHP framework? Honestly, all frameworks are fast enough anyways, but the point is this: you're building on a seriously awesome foundation.
See http://www.phpbenchmarks.com for the third-party benchmark stats!
Ok, let's get started already! Open a new terminal and move into whatever directory you want. Make sure that you already have Composer installed globally so that you can just say
composer. If you have any questions, ask us in the comments!
And also make sure you have the latest version:
That's important: Composer had a recent bug fix to help Symfony.
To download your new Symfony project, run
composer create-project symfony/skeleton and put this into a new directory called
composer create-project symfony/skeleton the_spacebar '4.4.*'
That's the name of our project! "The Spacebar" will be the place for people from across the galaxy to communicate, share news and argue about celebrities and BitCoin. It's going to be amazing!
This command clones the
symfony/skeleton project and then runs
composer install to download its dependencies.
Further down, there's something special: something about "recipes". OooOOO. Recipes are a new and very important concept. We'll talk about them in a few minutes.
And at the bottom, cool! Symfony gives us clear instructions about what to do next. Move into the new directory:
Apparently, we can run our app immediately by executing:
php -S 127.0.0.1:8000 -t public
This starts the built-in PHP web server, which is great for development.
public/ is the document root of the project - but more on that soon!
If you want to use Nginx or Apache for local development, you can! See http://bit.ly/symfony-web-servers.
Time to blast off! Move to your browser and go to
http://localhost:8000. Say hello to your new Symfony app!
Symfony no longer creates a Git repository automatically for you. But, no problem!
git init once to initialize your repository.
Back in the terminal, I'll create a new terminal tab. Symfony already inititalized a new git repository for us and gave us a perfect
.gitignore file. Thanks Symfony!
If you're using PhpStorm, you'll want to ignore the
.idea directory from git. I already have it
ignored in my global .gitignore file: https://help.github.com/articles/ignoring-files/
That means we can create our first commit just by saying:
git initgit add .git commit
Create a calm and well-thought-out commit message.
# Woohoo! OMG WE ARE USING SYMFONY4
Woh! Check this out: the entire project - including Composer and
.gitignore stuff - is only 16 files! Our app is teenie-tiny!
Let's learn more about our project next and setup our editor to make Symfony development amazing!
