Where is composer json symfony2

Sometimes a single feature requires installing several packages and bundles. Instead of installing them individually, Symfony provides packs , which are Composer metapackages that include several dependencies. For example, to add debugging features in your application, you can run the composer require --dev debug command. This means that it only adds the real packages as dependencies e. While it is not recommended, you can use the composer require --no-unpack The symfony binary created when you install Symfony CLI provides a command to check whether your project's dependencies contain any known security vulnerability:.

A good security practice is to execute this command regularly to be able to update or replace compromised dependencies as soon as possible. The security check is done locally by fetching the public PHP security advisories database , so your composer. The check:security command terminates with a non-zero exit code if any of your dependencies is affected by a known security vulnerability.

This way you can add it to your project build process and your continuous integration workflows to make them fail when there are vulnerabilities. According to the Symfony release process , "long-term support" or LTS for short versions are published every two years. Check out the Symfony releases to know which is the latest LTS version. By default, the command that creates new Symfony applications uses the latest stable version. If you want to use an LTS version, add the --version option:. The lts and next shortcuts are only available when using Symfony to create new projects.

If you use Composer, you need to tell the exact version:. The Symfony Demo Application is a fully-functional application that shows the recommended way to develop Symfony applications. It's a great learning tool for Symfony newcomers and its code contains tons of comments and helpful notes. With setup behind you, it's time to Create your first page in Symfony. Learn More. For example, PHP 8. Install Composer , which is used to install PHP packages. Note The Symfony binary is developed internally at Symfony.

The goal of this chapter is to get you up and running with a working application built on top of Symfony. Fortunately, Symfony offers "distributions", which are functional Symfony "starter" projects that you can download and begin developing in immediately. If you're looking for instructions on how best to create a new project and store it via source control, see Using Source Control. For more information on Symfony2 requirements, see the requirements reference.

Symfony2 packages "distributions", which are fully-functional applications that include the Symfony2 core libraries, a selection of useful bundles, a sensible directory structure and some default configuration. When you download a Symfony2 distribution, you're downloading a functional application skeleton that can be used immediately to begin developing your application. On this page, you'll see the Symfony Standard Edition , which is the main Symfony2 distribution.

There are 2 ways to get your project started:. Start by downloading Composer anywhere onto your local computer. If you have curl installed, it's as easy as:. If your computer is not ready to use Composer, you'll see some recommendations when running this command. Follow those recommendations to get Composer working properly. For an exact version, replace 2.

For details, see the Symfony Installation Page. To download the vendor files faster, add the --prefer-dist option at the end of any Composer command. This command may take several minutes to run as Composer downloads the Standard Distribution along with all of the vendor libraries that it needs.

When it finishes, you should have a directory that looks something like this:. Download one of the archives somewhere under your local web server's root directory and unpack it. From a UNIX command line, this can be done with one of the following commands replacing with your actual filename :.

You can easily override the default directory structure. At this point, you've downloaded a fully-functional Symfony project in which you'll start to develop your own application. A Symfony project depends on a number of external libraries. Depending on how you downloaded Symfony, you may or may not need to update your vendors right now. For more details about package naming and the fields you can use to document your package better, see the about page. Log in or register on this site, then hit the submit button in the menu.

Once you entered your public repository URL in there, your package will be automatically crawled periodically. You just have to make sure you keep the composer. Use Private Packagist if you want to share private code as a Composer package with colleagues or customers without publishing it for everyone on Packagist.

Private Packagist allows you to manage your own private Composer repository with per-user authentication, team management and integration in version control systems.
