----



== Installation ==

`npm(1)` is bundled with `node(1)`.

----


== Usage ==

Modules can be installed ''locally'' or ''globally''.

Local installation uses `./node_modules` for modules and `./node_modules/bin` for binaries. This is the default behavior.

{{{
npm install jquery
}}}

Global installation uses `$NPM_CONFIG_PREFIX/lib/node_modules` for modules and `$NPM_CONFIG_PREFIX/bin` for binaries. To enable this mode, include the `--global` flag (or `-g` for short).

{{{
npm install jquery -g
}}}

If `$NPM_CONFIG_PREFIX` is not set, the default can be inspected using:

{{{
NPM_CONFIG_PREFIX= npm prefix -g
}}}

----



== Configuration ==

`npm(1)` uses environment variables for configuration, all prefixed with `NPM_CONFIG_`.
