reenv

dotenv-cli implementation in native ReasonML. The goal is to have feature parity with dotenv but be implemented in Reason. If there is a feature missing please log an issue.

reenv is compiled as a binary and there is no node involved when running it as you can see in the benchmarks section.

Installation

reenv is available on all mainstream desktop platforms (Windows, macOS and Linux) and is installable via npm.

npm install -g reenv
