json2bash

Useful for CLIs, build scripts, CI scripts, or anywhere where your node app and surrounding bash scripts need to share state.

usage

Create an executable script like this, called something like "getenv"

#!/usr/bin/env node

const json2bash = require('@sean9999/json2bash');
const json = require('./package.json');
console.log(
    json2bash(json,'FOO')
);

Now call it from your bash script like this:

#!/bin/bash

eval "$(./getenv)"

echo "lets now look at our environment vars prefixed sith FOO"

env | grep FOO

The result looks like this
