Using PM2 in a Cloud Provider
You might find yourself in a situation in which you do not have access to the CLI to start your Node.js applications.
In such a situation, pm2 must be added as a dependency and must be called with the start script.
Prepare your app
Set your ecosystem file
Generate an ecosystem.config.js
template with:
pm2 init
Modify the ecosystem file to match your needs:
module.exports = {
apps : [{
name: "app",
script: "./app.js",
env: {
NODE_ENV: "development",
},
env_production: {
NODE_ENV: "production",
}
}]
}

Add PM2 as a module
Add pm2 as a dependency to your projet.
With npm:
npm install pm2
With yarn:
yarn add pm2
Start script in package.json
In your package.json
, modify your start
script like the following:
{
"scripts": {
"start": "pm2-runtime start ecosystem.config.js --env production"
}
}
Deploy your app
You can now deploy your application in your cloud providers like you would have done for a regular node.js app.
