README.md

example usage:

const envArray = [
  'PATH=/usr/local/bin:/usr/bin:/usr/sbin',
  'HOME=/home/alex',
  'FOO=bar'
];

const envObject = toEnvObject(envArray);
// {
//   'PATH': '/usr/local/bin:/usr/bin:/usr/sbin',
//   'HOME': '/home/alex',
//   'FOO': 'bar'
// }

const foo = envObject.FOO
// 'bar'

env.js

const toEnvObject = arr =>
  arr.filter(it => it.length > 0)
    .map(it => it.split('=', 2))
    .filter(([key]) => key.length > 0)
    .reduce((obj, [key, value]) => ({ ...obj, [key]: value }), {});

env.ts

const toEnvObject = (arr: string[]): { [key: string]: string } =>
  arr.filter(it => it.length > 0)
    .map(it => it.split('=', 2))
    .filter(([key]) => key.length > 0)
    .reduce((obj, [key, value]) => ({ ...obj, [key]: value }), {});
