Anyway Config: Keep your Ruby configuration sane

It’s time we have a serious conversation about configuration, settings, secrets, credentials, and environment variables in mature Ruby, and especially Rails projects. As a part of this friendly intervention, I will introduce Anyway Config, a gem of my design that keeps project configuration sane at Evil Martians, and, hopefully, will help you escape the “ENV Hell.”Configuration is one of the most critical markers of codebase health: the more your application grows and matures, the harder it is to deal with API keys, .env files, and other settings. In my RailsConf 2019 talk “Terraforming legacy Rails applications” (slides, video), I talked about “ENV Hell”—something I’m sure most of the readers working on larger Ruby apps are familiar with.
