Example create .env files key=value =" and ='' or =

touch .env
cat > .env <<'EOL'
FOO="Bar"
TEST=DATA

var {env} = require('@zaeny/env');
env()

/*
  { FOO: 'Bar', TEST: 'DATA', BAR: 'apapa'}  
  added to process.env[]
*/

// select different files
env('./environment'); 

Implementation

this utility function free to copy

/* author: https://github.com/azizzaeny/env */

function env(file=".env", state=process.env){
  var {readFileSync, existsSync} = require('fs');
  if(!existsSync(file)) return console.log('no file', file);
  let contents = readFileSync(file, 'utf8');  
  let params= contents.split('\n').map((line)=>line.split('=')).reduce((k, [key, value])=>{
    if(value && (value.startsWith('"') || value.startsWith("'"))) (value = value.slice(1, -1));
    return (value) ? ((state[key]=value), Object.assign(k,{[key] : value.trim()})) : k ;
  },{});
  return params
}

module.exports = { env }
