I built this package while working on an app that I deployed to production, staging and my local dev environment. I had a couple of scripts (one to deploy, one to migrate the database, etc.) that I wanted to run, but I didn't want to have to maintain one script for each environment doing almost the same but to different endpoints.<p>So, I built a simple CLI that reads one or more .env files and spawns a new child process running an NPM script from the package, with the environment variables extended with the contents of the files.<p>It also supports expansion, where one file use the value defined in another file.<p>Please see the README for more details and usage and consider giving it a spin in your next project if you're faced with a similar problem.
