A well-supported package, plus several tools that you can learn once and use the same for any language or combo of languages. And those will still work when you have to git-bisect back to a version of your project that doesn’t have built-in .env setting. Shipping this specific thing with nodejs seems deeply pointless to me. Plus, having my program auto-monkey with its own environment, even optionally, feels… wrong. I should define it (or something should on my behalf) and the program should accept what it gets. Else, why even use env vars? Just use a config toml or some shit. But that part reasonable people could disagree over.
