On the SitePoint PHP blog they've posted a tutorial from author Francesco Malatesta covering his Laravel package building workflow.
Packages are a really important part of the Laravel experience (just like with any other framework). Whatever we need to do, there’s probably already a package for it out there; ready for a composer require to bring some magic in.
Some weeks ago, I had an idea for a new one. I work for AdEspresso, where we have a Symfony FeatureBundle, which handles feature toggling in our projects. It’s a really nice piece of code that we use to release new features only for specific subsets of users. So, I asked myself… why not port it for Laravel? That’s how my Laravel Feature package idea was born.
[...] In this article, I will try to explain how I prepared my development environment for it, and which choices I made when building the package. Not the development of every line of code per-se, but the actual workflow of getting from nothing to a full package.
He starts by talking about a handy addition to an application that can make the rollout of your new package easier: feature flags. He then starts in talking about the Composer configuration of the package and its "skeleton" (default directory and file structure). The tutorial then starts in on the code in the package itself covering the abstraction of domain code and implementing the features including the configuration, Blade template and the matching facade.
