While I was at Raise.dev, one early problem to solve was improving the developer experience. At the time, I was working alongside a designer and later another developer, so the app environment needed to be easy to set up and configure. One way in which this was achieved was through Scripts to Rule Them All, but a novel way I introduced was to have all required environment variables checked at boot time. After Raise.dev was retired, I released the source for this as
nvar allows Ruby developers to specify the environment variables used within their app, whether or not they are required, and whether or not they need to be censored from requests recorded in tests via VCR. The aim is to centralize all configuration linked to environment variables through
nvar. It works very well when paired with
dotenv-rails, but doesn't require it.
The initial feature of checking the environment at boot time was key to ensuring a good developer experience at Raise.dev, but the features that followed on from that evolved
nvar into what I believe to be an indispensable tool for Rails developers.
