pm2.web - Backend

The Backend is a simple Node.js application that uses the pm2 BUS API to communicate and monitor pm2 processes. It doesn't require any open ports, since it only saves data to the database, and events like restart, stop, and delete are relayed through the change stream of MongoDB.

Prerequisites

  • Node.js v18
  • MongoDB Cluster
  • PM2 (installed globally)

Configuration

DB_URI=<MongoDB URI>
SERVER_NAME=used instead of the host name (optional)

Installation

  1. Install the dependencies

    # run from the project root
npm install

  2. Create a .env file in the apps/backend directory and add the following variables

    DB_URI=<MongoDB URI>

Setup

# run from the project root
npm run start:apps:backend

To run the process in the background, you can use several tools such as PM2.
