Different ways to shell out in node

shell.js

const childProcess = require('child_process');

function runShell(cmd, args, options) {
  const output = childProcess.spawnSync(cmd, args, options);

  return output.stdout.toString();
};

// 1. With just the base command
const findCmd = `find app/assets -type f -name *.js -not \( -path *spec* \) -o -name *.coffee -not \( -path *spec* \)`;
const cmdArr = findCmd.split(' ');
let sourceFiles = runShell(cmdArr[0], cmdArr.slice(1));

// 2. Using `sh`
sourceFiles = runShell('sh', ['-c', `find app/assets -type f -name '*.js' -not \\( -path '*spec*' \\) -o -name '*.coffee' -not \\( -path '*spec*' \\)`]);

// NOTES
// Quotes are dropped for file extensions in #1
// Need to double escape slashes for parens in #2
