Package Versions

A message to Russian 🇷🇺 people

If you currently live in Russia, please read this message.

Purpose

This utility provides quick and easy access to version information of composer dependencies.

This information is derived from the composer.lock file which is (re)generated during composer install or composer update.

$version = \PackageVersions\Versions::getVersion('ocramius/package-versions');

var_dump($version); // 1.0.0@0beec7b5ea3f0fdbc95d0dd47f3c5bc275da8a33

Installation

composer require ocramius/package-versions

It is suggested that you use an optimized composer autoloader (to prevent autoload I/O when accessing the PackageVersions\Versions API) in your composer.json:

...
    "config": {
        "optimize-autoloader": true
    },
...

In case you manually generate your autoloader via the CLI use the --optimize flag:

composer dump-autoload --optimize

Use-cases

This repository implements PackageVersions\Versions::getVersion() in such a way that no IO happens when calling it, because the list of package versions is compiled during composer installation.

This is especially useful when you want to generate assets/code/artifacts that are computed from the current version of a certain dependency. Doing so at runtime by checking the installed version of a package would be too expensive, and this package mitigates that.
