Building a good CI/CD pipeline can take some time. The pipeline is very interesting for larger projects because it automates going from local development to a staging and/or production environment. It also facilitates the teamwork between developers. So all in all... CI/CD, it has a lot of advantages.
Even on smaller projects, it is interesting to build a decent pipeline... A smaller project usually means smaller budget. Which pipeline can a developer quickly set up for a small project ? ... Enter PM2 deploy!
PM2 is a process manager for NodeJS. It does this quite well because it has very interesting features. Features such as : zero downtime reloads, max memory reloads, monitoring & log management, hot reload, cluster mode, ... and off course deployment worflow.
CI/CD is an abbreviation of Continuous Integration & Continuous Deployment (or Delivery).
Integration is usually automated testing and deployment is is often referred as going from a local environment to a staging and production environment. Even though I won't say much about version control systems, it is an important part of CI/CD.
