    Heroku JS Runtime Env

    Use runtime environment variables in bundled/minified javascript apps.

    Build Status npm Module

    Usage

    Designed for create-react-app-buildpack. See its documentation to use this module for Runtime configuration.

    Background

    Normally javascript apps are compiled into a bundle before being deployed. During this build phase, environment variables may be embedded in the javascript bundle, such as with Webpack DefinePlugin.

    When hosting on a 12-factor platform like Heroku, these embedded values may go stale when setting new config vars or promoting through a pipeline.

    How Does It Work?

    When developing your app, use Runtime environment variables from create-react-app-buildpack.

    Then, each time the app starts-up on Heroku, a .profile.d script (installed from the buildpack) is executed which fills in a JSON placeholder in the JavaScript bundle with the runtime environment variables. The result is 🍃fresh runtime environment variables in the production javascript bundle without recompiling.

    Install

    npm i @avantsoft/js-runtime-env
