Composer is a tool that helps find, install and update library packages that your PHP project depends on. Libraries are installed in the project's root directory. The Composer utility is available as part of Plesk. You do not need to install Composer in your project manually. Plesk installs the updates for Composer once a week.
Composer uses two files for storing the list of modules necessary for the project:
composer.json- lists libraries on which your project depends directly.
composer.jsonto the root directory of your project and specify packages. You can use the '
composer init'command to create
composer.lock- lists all libraries on which the libraries in
composer.jsondepend directly and indirectly, thus containing all libraries necessary for your project.
For more information, refer to Composer documentation at https://getcomposer.org/doc/.
Plesk offers two ways to use Composer:
- Through the command line. Refer to the Composer documentation for instructions.
Note: Use normal environment (not chrooted).
- Through Websites & Domains > Applications. See the instructions below.
