Packagist is the main Composer repository, serving as the primary hub for PHP package distribution. It is a decentralized package repository that allows developers to share and find packages of PHP code.
History
Packagist was launched to facilitate the distribution of PHP packages through Composer, a dependency manager for PHP. The service was introduced in 2012 by Jordi Boggiano and Nils Adermann, who are also the creators of Composer. Packagist was created to solve the issue of package discovery and management in PHP, providing a central place where developers could publish their libraries, frameworks, and other PHP code packages.
Functionality
- Package Hosting: Developers can submit their packages to Packagist, which then indexes them, making them discoverable and installable via Composer.
- Version Control: Packagist supports versioning, allowing users to specify which versions of packages they require in their projects.
- Dependency Resolution: It assists in resolving dependencies, ensuring that all required packages and their dependencies are compatible and can be installed together.
- Metadata: Each package on Packagist comes with metadata like authors, version numbers, license information, and links to documentation or source code repositories.
- API Access: Packagist provides an API that allows for programmatic interaction with the repository, useful for tools and services that integrate with PHP package management.
Integration with Composer
Packagist works closely with Composer by:
- Automatically updating package information when a package's source repository (like GitHub or GitLab) changes.
- Providing a searchable interface for package discovery within the Composer command line tool.
- Enabling developers to manage their dependencies by specifying them in the
composer.json file, which Composer uses to pull packages from Packagist.
Community and Governance
Packagist is community-driven, with governance from the PHP-FIG (PHP Framework Interoperability Group), which ensures standards and best practices are maintained. It encourages contributions from developers worldwide, promoting an open-source ethos where anyone can contribute or fork the code hosted on Packagist.
Security
Packagist takes security seriously, implementing measures like:
- Verification of packages through signed commits or tags.
- Security advisories to inform users about vulnerabilities in packages.
- Integration with tools like GitHub's security advisories to automatically notify about security issues.
