Create a simple Composer – Packagist PHP package This little article will guide you to create a simple composer package. What is Composer? Composer is a dependency manager for PHP. The way I’d like to look at it is – Composer facilitates the inclusion / reference of external PHP libraries in your project. In this article, we will talk about how to create a composer package instead of how to reference a library in your project. The main points Create a repository on Github for your library Your library needs to follow a simple file / folder structure Your library should contain a composer.json file You need to submit the Github repo link into Packagist Create a repository on Github I am sure you know how to do this pretty well. So go ahead and create one. Library folder structure Follow the below structure repo | composer.json \ src \ HelloWorld \ HelloWorld.php composer.json This file mentions the configuration or setup of your composer package. See the example file below { “name”: “1985apps/inlineemail”, “autoload”: { “psr0”: { “InlineEmail”: “src” } } } name: vendor/package psr0: namespace : path to files to include Submit your repository to Packagist This is the easy part. Create an account at Packagist Click on the “submit” link Mention your Github link That’s it! Now anyone can include your package by using this (in their project’s composer.json). requires: { “vendor/package”: “devmaster” } You can use our package (1985apps/inlineemail) as a reference on how to go about it. Feel free to download it, move files around and see how it works Helpful links: 1985apps/email: https://github.com/1985apps/inlineemail Similar guide at Junior Grosse: http://grossi.io/2013/creatingyourfirstcomposer- packagistpackage/ Composer: https://getcomposer.org/ Packagist: https://packagist.org
