Check composer-version

Overview

Checks the installed Composer version against the endoflife.date API and alerts if the version is end-of-life or if newer major, minor, or patch releases are available. By default, alerts 30 days before the official EOL date. The offset is configurable.

Important Notes:

  • The check must run on the machine where Composer is installed

  • Optionally alerts on available major, minor, or patch releases independently of EOL status via --check-major, --check-minor, and --check-patch

Data Collection:

  • Runs composer --version at the configured --path (default: /usr/bin/composer) to determine the installed version

  • Queries the endoflife.date API (https://endoflife.date/api/composer.json) for lifecycle data

  • Caches API responses locally in an SQLite database to reduce network requests
