Discover why process managers like PM2 are helpful for managing Node.js processes and microservices.
- [Instructor] We've got a couple different options…for running Node.js Services.…The easiest way would be to start each manually with node.…However, you'd have to start each process one at a time,…and it doesn't watch and restart with changes.…There's also nodemon, but it's also limited…to one process at a time,…and it's intended only for development.…How can we manage multiple Node.js processes…at the same time?…We're going to use PM2, which is a Node.js process manager.…
What's that mean?…A Node.js process manager is a service…that runs in the background.…Meaning it runs behind the scenes,…and without user interaction.…They're used to control and mange Node.js processes.…This includes operations like starting,…stopping and restarting on changes or errors.…They also monitor resource usage, like CPU or memory.…Finally, they gather logs in one place,…which is convenient for debugging and log management.…
Process managers are essential debugging…and performance tools for a number of reasons.…You can see the number of times the process is restarted,…
