Envlet for Ruby

Envlet.inject fills ENV before Rails or Sinatra boots. One gem, nothing else.

Inject

require "envlet"

Envlet.inject

Stripe.api_key = ENV["STRIPE_KEY"]

Load

require "envlet"

values = Envlet.load

db = PG.connect(values["DATABASE_URL"])

Get

require "envlet"

stripe_key = Envlet.get("STRIPE_KEY")

Install

gem install envlet

Set up

01
Install
gem install envlet or add gem "envlet" to your Gemfile.
02
Set one secret
ENVLET_TOKEN in the process environment.
03
Inject at boot
Require envlet and call Envlet.inject at the top of config/boot.rb or your entrypoint.

Will my app start if Envlet is down?: No, and that is the point. The SDK retries for a few seconds, then fails so you notice. It never starts your app with half an environment.
What does the host need?: One variable, ENVLET_TOKEN. Everything else arrives at boot.
Can I still set some values on the Ruby host?: Yes. A value the host already set wins. Pass override if you want Envlet to win instead.

One command. The right values for whoever runs it.
