PM2: what is 'version' and why is it always '0.1.0'?

Question

I am using pm2 to control some node applications. When I check pm2 apps using pm2 ps I get an output similar to this one:

┌─────┬─────────┬─────────────┬─────────┬─────────┬──────────┬────────┬──────┬───────────┬──────────┬──────────┬──────────┬──────────┐
│ id  │ name    │ namespace   │ version │ mode    │ pid      │ uptime │ ↺    │ status    │ cpu      │ mem      │ user     │ watching │
├─────┼─────────┼─────────────┼─────────┼─────────┼──────────┼────────┼──────┼───────────┼──────────┼──────────┼──────────┼──────────┤
│ 0   │ dlnk    │ default     │ 0.1.0   │ fork    │ 32210    │ 9s     │ 0    │ online    │ 7.4%     │ 61.7mb   │ fabio    │ enabled  │
└─────┴─────────┴─────────────┴─────────┴─────────┴──────────┴────────┴──────┴───────────┴──────────┴──────────┴──────────┴──────────┘

What is the version column for? Is it possible to change it using some field in the ecosystem.conf.js file?

Answer 1

It shows the version number in your package.json file.
