. <(npm completion)
Enables tab-completion in all npm commands.
The synopsis above loads the completions into your current shell. Adding it to your ~/.bashrc or ~/.zshrc will make the completions available everywhere.
You may of course also pipe the output of npm completion to a file such as /usr/local/etc/bash_completion.d/npm
if you have a system that will read that file for you.
When COMP_CWORD
, COMP_LINE
, and COMP_POINT
are defined in the environment, npm completion
acts in “plumbing mode”, and outputs completions based on the arguments.
