install dotenvx to heroku

heroku buildpacks:add https://github.com/dotenvx/heroku-buildpack-dotenvx

Usage

Add dotenvx to your Procfile.

# Procfile
web: dotenvx run -- node index.js

Set DOTENV_KEY on heroku.

heroku config:set DOTENV_KEY='dotenv://:key_1234...@dotenvx.com/vault/.env.vault?environment=production'

On deploy, dotenvx will decrypt your .env.vault file using the DOTENV_KEY and inject your env just in time.

$ heroku logs --tail
heroku[web.1]: Starting process with command `dotenvx run -- node index.js`
app[web.1]: [dotenvx@0.9.0] injecting env (1) from encrypted .env.vault
