Package Development & Publishing

Publishing a reusable Composer package follows PSR-4 (from Level 2) plus a public composer.json and a version tag on GitHub — Packagist is the public package registry Composer pulls from by default.

{
    "name": "yourname/text-utils",
    "type": "library",
    "autoload": {
        "psr-4": { "YourName\\TextUtils\\": "src/" }
    },
    "require": {
        "php": "^8.2"
    }
}

Tagging a Git release (v1.0.0) and submitting the repository to packagist.org is all that's needed for anyone to composer require yourname/text-utils.
