<p>npm gets its config settings from the command line, environment
variables, and <code class="language-text">npmrc</code> files.</p>
<p>The <code class="language-text">npm config</code> command can be used to update and edit the contents
of the user and global npmrc files.</p>
<p>For a list of available configuration options, see <a href="../../using-npm/config">config</a>.</p>

<p>The four relevant files are:</p>
<ul>
<li>per-project config file (/path/to/my/project/.npmrc)</li>
<li>per-user config file (~/.npmrc)</li>
<li>global config file ($PREFIX/etc/npmrc)</li>
<li>npm builtin config file (/path/to/npm/npmrc)</li>
</ul>
<p>All npm config files are an ini-formatted list of <code class="language-text">key = value</code>
parameters. Environment variables can be replaced using
<code class="language-text">${VARIABLE_NAME}</code>. For example:</p>
<div class="gatsby-highlight" data-language="bash"><pre class="language-bash"><code class="language-bash">prefix <span class="token operator">=</span> <span class="token variable">${<span class="token environment constant">HOME</span>}</span>/.npm-packages</code></pre></div>
<p>Each of these files is loaded, and config options are resolved in
priority order. For example, a setting in the userconfig file would
override the setting in the globalconfig file.</p>
<p>Array values are specified by adding "[]" after the key name. For
example:</p>
<div class="gatsby-highlight" data-language="bash"><pre class="language-bash"><code class="language-bash">key<span class="token punctuation">[</span><span class="token punctuation">]</span> <span class="token operator">=</span> <span class="token string">"first value"</span>
key<span class="token punctuation">[</span><span class="token punctuation">]</span> <span class="token operator">=</span> <span class="token string">"second value"</span></code></pre></div>

<p>Lines in <code class="language-text">.npmrc</code> files are interpreted as comments when they begin with a <code class="language-text">;</code> or <code class="language-text">#</code> character. <code class="language-text">.npmrc</code> files are parsed by <a href="https://github.com/npm/ini">npm/ini</a>, which specifies this comment syntax.</p>
<p>For example:</p>
<div class="gatsby-highlight" data-language="bash"><pre class="language-bash"><code class="language-bash"><span class="token comment"># last modified: 01 Jan 2016</span>
<span class="token punctuation">;</span> Set a new registry <span class="token keyword">for</span> a scoped package

<p>When working locally in a project, a <code class="language-text">.npmrc</code> file in the root of the
project (ie, a sibling of <code class="language-text">node_modules</code> and <code class="language-text">package.json</code>) will set
config values specific to this project.</p>
<p>Note that this only applies to the root of the project that you're
running npm in. It has no effect when your module is published. For
example, you can't publish a module that forces itself to install
globally, or in a different location.</p>
<p>Additionally, this file is not read in global mode, such as when running
<code class="language-text">npm install -g</code>.</p>

<p>This is an unchangeable "builtin" configuration file that npm keeps
consistent across updates. Set fields in here using the <code class="language-text">./configure</code>
script that comes with npm. This is primarily for distribution
maintainers to override default configs in a standard and consistent
manner.</p>
