How to deploy with pm2 Javascript applications — boobo94

Today I talk with you about how to deploy with pm2. I want to present a simple example for a node.js app, but you can use it to deploy react, Vue or other Javascript apps.

I know how frustrating is for some of you this part about devops. That’s why pm2 comes throw us like an angel which wants to save the humanity in front of Continous Deployment process.

Pm2 configuration file

{
  "apps": [{
    "name": "App",
    "script": "./app.js",
 
    "autorestart": true,
    "watch": false,
    "max_memory_restart": "1G",
    "env": {
      "NODE_ENV": "development",
    },
    "env_production": {
      "NODE_ENV": "production",
    }
  }],

    "development": {
      "user": "user",
      "host": "111.111.111.111",
      "ref": "origin/develop",
      "repo": "git clone git@github.com:repo.git",
      "path": "/var/www/development",
      "post-deploy": "cd /var/www/development && npm install && pm2 reload ecosystem.json"
    },
    "production": {

    }
  }
