Solution

I guess in javascript there exists a library to generate shell completions automatically like

• https://docs.iterative.ai/shtab/use/#library-usage
• https://click.palletsprojects.com/en/8.1.x/shell-completion/
• https://docs.rs/clap_complete/latest/clap_complete/
• https://jmtirado.net/shell-completion-with-cobra-and-go/

Alternatives

Don't use any library, like https://github.com/ytdl-org/youtube-dl/blob/master/devscripts or https://github.com/ogham/exa/tree/master/completions?
