Option 1: git revert HEAD or git reset --hard <commit-hash>, then npm install and pm2 reload. Option 2: Keep a previous directory (devtinder-backend-prev) and switch PM2 to it: pm2 stop, pm2 delete, cd to prev directory, pm2 start.
A JavaScript file (ecosystem.config.js) that defines app configuration: name, script, instances (max for all cores), exec_mode (cluster), max_memory_restart, environment variables, and log file paths. Start with pm2 start ecosystem.config.js.
