Restart when app crashed.

[zhangweis]

I'd like to use denon as for forever of nodejs.
When the app crashes, it says 'app crashed - waiting for file changes before starting ...' and I'd like it to restart it automatically.
At least an option to restart when an app crashed.

Check out https://github.com/hexagon/pup for an alternative supporting this and much more.

The most simple mode, without a configuration file is documented in the "Single command usage" section of https://hexagon.github.io/pup/usage.html

To restart a process on errors, and also when a file in the current directory changes, the command should be

pup -nAc "deno run my-script.ts" -w .

Where -w . is short for --watch . which watches the current directory (.)

-n is short for --no-config

-A is short for --autostart

-c is short for --cmd
