pm2/examples/configuration-process-files

Here we have 3 applications (apps folder) that we can start with process file. These process file can be of different format, javascript, json or yaml:

.
├── apps
│   ├── connection_check.sh
│   ├── http.js
│   └── worker.js
├── process.config.js
├── process.json
└── process.yml

To start them:

$ pm2 start process.config.js
$ pm2 delete all
$ pm2 start process.json
$ pm2 delete all
$ pm2 start process.yml
