Composer Repositories

Composer is a dependency manager for PHP. You declare the libraries your project depends on, and Composer installs and updates them.

See the Composer documentation

Nexus Repository provides Composer repository support so that you can cache packages from external Composer repositories, host internal and third-party packages, and expose multiple Composer repositories through a single group endpoint.

Composer repositories are available on Sonatype Cloud and Nexus self-hosted Pro deployments.

Note

  • Nexus Repository native Composer support does not support migration from the Community Composer plugin.

  • Nexus Repository supports the Composer v2 protocol only. You cannot proxy repositories that provide only Composer v1 metadata, such as the Magento Composer repository.
