For example, many developers use Github or Bitbucket, popular services that provide code storage, to store their code in the cloud. While is the default repository Composer searches, projects can also define custom repositories that Composer will search for libraries.

UPDATE DRUPAL CORE COMPOSER INSTALL

If any conflicts are found, Composer shows an error and will not install the libraries until the conflicts have been resolved. It also checks to make sure that your system has the minimum requirements to handle both Library A and Library B and any other dependencies, and also checks if either of these packages have any conflicts with any other libraries you've installed. If Library A depends upon (aka requires) Library B, then it will also download Library B to your system, and so on. When a user says ‘Composer download Library A’, the Composer program looks for Library A on, the main public Composer repository, and if it finds the Library, it downloads it to your system. This is a site that has been set up specifically for Composer, and contains thousands of public libraries that developers have provided for use. Libraries are also known as Packages, and referred to as such on Ī project is the codebase, generally for a website or application, that is being managed by Composer.īy default, the main repository Composer looks at is. In this article, the term Library is used. When Composer finds Library A in a repository, it downloads the library, as well as any libraries that Library A is dependent upon. A repository is a server that provides a collection of libraries for download. Composer searches remote repositories for libraries. After a user has installed Composer, they can then say ‘Composer: download Library A to my system’.

Update the library and its dependencies with a single commandĬomposer itself is a software/program.Ensure there are no version conflicts between libraries.Check that system requirements are met before installing the library.Download and include any libraries that library is dependent upon.Download and include a library into a project, with a single command.Using Composer, developers can include this library in a project, and use it to authenticate to the remote API, saving the developer from having to write that code.Ĭomposer allows developers to do the following: A library is basically a set of code that can be re-used by other sites. However, other developers have written code that handles OAuth 2 integration, and they have released this code on the internet in the form of a library. Writing OAuth 2 integrations is tricky, as the authentication process is somewhat complex. This is a secure protocol that allows sites or applications to authenticate with other sites, such as Facebook, Google, Twitter, Instagram, and countless others. For example, the current standard for authentication (aka logging in) to remote systems is the OAuth 2 protocol.

DRY is another way of saying don’t re-invent the wheel if someone else has already written code that does what you want to do, rather than writing code that does the same thing, it’s better to re-use the code that that has already been written. Traditionally, this referred to code within the codebase of a single application, but with Composer, code can now be shared between applications as well.

This means that whenever possible, code should be re-used, rather than re-written. Programmers like to use the term DRY - Don’t Repeat Yourself. So let’s break it down a little further to understand what it means. That’s an accurate description, though a little wordy.

UPDATE DRUPAL CORE COMPOSER SOFTWARE

The Wikipedia page ( (software)) describes Composer as follows:Ĭomposer is an application-level package manager for the PHP programming language that provides a standard format for managing dependencies of PHP software and required libraries. So without further ado, let’s get started.

UPDATE DRUPAL CORE COMPOSER SERIES

This is the first post in an explorative series of blog posts on Drupal and Composer, hopefully clearing up some of the confusion. This can be daunting for those without previous experience working with the command line, and can still be a confusing experience for those who do. As any developer working with Drupal 8 knows, working with Composer has become an integral part of working with Drupal.
