A node script to make commits every 5 minutes

git-scheduled-auto-commit.js

#!/usr/bin/env node

const readline = require('readline');
const { execFileSync } = require('child_process');

const [minutes, yes] = process.argv.slice(2);
const interval = 60 * 1000 * minutes;
const cwd = process.cwd();

if (!minutes || parseInt(minutes) === NaN) {
  console.error('Add a (real) minutes argument e.g. <./gaca 5>');
  process.exit(1);
}

let timeout;
process.on('exit', () => clearTimeout(timeout));
process.stdin.resume();

const save = () => {
  console.log('🔍 Checking for changes');
  const changedFiles = execFileSync('git', ['status', '--porcelain'], {
    cwd,
    encoding: 'utf8',
  });

  if (!changedFiles) {
    console.log('🍽  No changes were found');
  } else {
    console.log('🙌 New changes found');
    execFileSync('git', ['add', '--all'], { cwd, encoding: 'utf8' });

    console.log('👩‍🍳 Making a fresh commit');
    execFileSync(
      'git',
      [
        'commit',
        '--allow-empty',
        '-nm',
        `"auto commit at ${new Date().toJSON()}"`,
      ],
      { cwd, encoding: 'utf8' }
    );
    console.log('🧁  New commit added');
  }

  console.log(
    `⏲  Another commit is scheduled to be made ${minutes} minute${
      minutes === 1 ? '' : 's'
    } from ${new Date().toJSON()} (roughly)`
  );
  timeout = setTimeout(save, interval);
};

const start = () => {
  try {
    save();
  } catch (error) {
    console.error(error);
    process.exit((error && error.exitCode) || 1);
  }
};

{
  const rl = readline.createInterface(process.stdin, process.stdout);
  rl.question('Are you sure (Y/n)? ', (answer = 'Y') => {
    rl.close();

    if (['Y', ''].includes(answer.trim().toUpperCase())) {
      start();
    } else {
      console.log('😑 no auto commits scheduled');
      process.exit(0);
    }
  });
}

The objective was to use only native node.js 🤓.

I usually run this on an experiment branch to keep the noise down on the true working branch 🔇.
