[FEATURE] Using npm start

[martadinata666]

Is your feature request related to a problem? Please describe.
By default the youtubedl-m use PM2 runtime, that need installed manually npm install -g pm2 that need use root permission. By using npm start in package.json. We can include pm2 in backend dependencies and set npm start to pm2-runtime --raw pm2.config.js then dropping the need install pm2-runtime with root permission.

Looking from

YoutubeDL-Material/backend/package.json

Line 8 in 6fa4296

"start": "nodemon app.js",

seems youtubedl-m used to be using nodemon and spoiler: i tried and it not working.

Describe the solution you'd like

1. Change npm start to pm2-runtime --raw pm2.config.js
2. Add pm2-runtime to backend dependencies

Additional context
Using npm start will likely easier reproducible runtime, as user doesn't need to manually install pm2.

I removed all references to nodemon: 0ffd702

I'm not an npm expert, but I'm not positive that adding pm2-runtime to package.json in backend will work (https://stackoverflow.com/a/10813149/8088021). The instructions on the npm page also only say to use the -g.

Does npm start circumvent this somehow by including commands from node_modules?

[martadinata666]

I tried locally it work fine, npm will include command from node_modules.
This some behaviour covered when pm2 installed locally.

debian@18fc2d8d6978:~/youtubedl-material$ cat package.json | grep start
    "start": "pm2-runtime --raw pm2.config.js",
      "restart_update.json",
      "restart_general.json"
debian@18fc2d8d6978:~/youtubedl-material$ pm2-runtime --raw pm2.config.js
bash: pm2-runtime: command not found
debian@18fc2d8d6978:~/youtubedl-material$ npm start

> backend@1.0.0 start
> pm2-runtime --raw pm2.config.js

The caveat is, when run the binaries directly need to use npx.

debian@18fc2d8d6978:~/youtubedl-material$ pm2 list
bash: pm2: command not found
debian@18fc2d8d6978:~/youtubedl-material$ npx pm2 list

But it just preferences, as i prefer reduce usage of root installation much as possible.
