zsh-better-npm-completion

Better completion for npm

• Makes npm install recommendations from npm cache
• Makes npm uninstall recommendations from dependencies/devDependencies
• Shows detailed information on script contents for npm run
• Falls back to default npm completions if we don't have anything better

Installation

As an Oh My ZSH! custom plugin

Clone zsh-better-npm-completion into your custom plugins repo

git clone https://github.com/gentslava/zsh-better-npm-completion.git $ZSH_CUSTOM/plugins/zsh-better-npm-completion

Then load as a plugin in your .zshrc

plugins+=(zsh-better-npm-completion)

Manually

Clone this repository somewhere (~/.zsh-better-npm-completion for example)

git clone https://github.com/gentslava/zsh-better-npm-completion.git ~/.zsh-better-npm-completion

Then source it in your .zshrc

source ~/.zsh-better-npm-completion/zsh-better-npm-completion.plugin.zsh

Module Install Cache

When running npm install rea<tab>, it will perform an npm search for matching packages. In addition it will look in your local npm cache directory for package suggestions. However building this list can be pretty slow. This completion makes use of the zsh completion caching mechanism to cache the module list if you have caching enabled.

We try to enable it by default, however if you have something like below in your zshrc forces cache for all completions to be turned off.

zstyle ':completion:*' use-cache off

To specifically turn npm cache back on, you may add the following:

zstyle ':completion::complete:npm::' use-cache on

By default the cache will be valid for 1 hour. But can be modified by setting a cache policy like this:

_npm_install_cache_policy() {
  # rebuild if cache is more than 24 hours old
  local -a oldp
  # See http://zsh.sourceforge.net/Doc/Release/Expansion.html#Glob-Qualifiers
  # Nmh+24 ... N == NULL_GLOB, m == modified time, h == hour, +24 == +24 units (i.e. [M]onth, [w]weeks, [h]ours, [m]inutes, [s]econds)
  oldp=( "$1"(Nmh+24) )
  (( $#oldp ))
}
zstyle ':completion::complete:npm::' cache-policy _npm_install_cache_policy
