<div id="_content"><h3 id="description">Description</h3>
|
||
|
|
<p>Commands like <code>npm install</code> and the dependency sections in the
|
||
|
|
<code>package.json</code> use a package name specifier. This can be many different
|
||
|
|
things that all refer to a "package". Examples include a package name,
|
||
|
|
git url, tarball, or local directory. These will generally be referred
|
||
|
|
to as <code><package-spec></code> in the help output for the npm commands that use
|
||
|
|
this package name specifier.</p>
|
||
|
|
<h3 id="package-name">Package name</h3>
|
||
|
|
<ul>
|
||
|
|
<li><code>[<@scope>/]<pkg></code></li>
|
||
|
|
<li><code>[<@scope>/]<pkg>@<tag></code></li>
|
||
|
|
<li><code>[<@scope>/]<pkg>@<version></code></li>
|
||
|
|
<li><code>[<@scope>/]<pkg>@<version range></code></li>
|
||
|
|
</ul>
|
||
|
|
<p>Refers to a package by name, with or without a scope, and optionally
|
||
|
|
tag, version, or version range. This is typically used in combination
|
||
|
|
with the <a href="../using-npm/config#registry.html">registry</a> config to refer to a
|
||
|
|
package in a registry.</p>
|
||
|
|
<p>Examples:</p>
|
||
|
|
<ul>
|
||
|
|
<li><code>npm</code></li>
|
||
|
|
<li><code>@npmcli/arborist</code></li>
|
||
|
|
<li><code>@npmcli/arborist@latest</code></li>
|
||
|
|
<li><code>npm@6.13.1</code></li>
|
||
|
|
<li><code>npm@^4.0.0</code></li>
|
||
|
|
</ul>
|
||
|
|
<h3 id="aliases">Aliases</h3>
|
||
|
|
<ul>
|
||
|
|
<li><code><alias>@npm:<name></code></li>
|
||
|
|
</ul>
|
||
|
|
<p>Primarily used by commands like <code>npm install</code> and in the dependency
|
||
|
|
sections in the <code>package.json</code>, this refers to a package by an alias.
|
||
|
|
The <code><alias></code> is the name of the package as it is reified in the
|
||
|
|
<code>node_modules</code> folder, and the <code><name></code> refers to a package name as
|
||
|
|
found in the configured registry.</p>
|
||
|
|
<p>See <code>Package name</code> above for more info on referring to a package by
|
||
|
|
name, and <a href="../using-npm/config#registry.html">registry</a> for configuring which
|
||
|
|
registry is used when referring to a package by name.</p>
|
||
|
|
<p>Examples:</p>
|
||
|
|
<ul>
|
||
|
|
<li><code>semver:@npm:@npmcli/semver-with-patch</code></li>
|
||
|
|
<li><code>semver:@npm:semver@7.2.2</code></li>
|
||
|
|
<li><code>semver:@npm:semver@legacy</code></li>
|
||
|
|
</ul>
|
||
|
|
<h3 id="folders">Folders</h3>
|
||
|
|
<ul>
|
||
|
|
<li><code><folder></code></li>
|
||
|
|
</ul>
|
||
|
|
<p>This refers to a package on the local filesystem. Specifically this is
|
||
|
|
a folder with a <code>package.json</code> file in it. This <em>should</em> always be
|
||
|
|
prefixed with a <code>/</code> or <code>./</code> (or your OS equivalent) to reduce confusion.
|
||
|
|
npm currently will parse a string with more than one <code>/</code> in it as a
|
||
|
|
folder, but this is legacy behavior that may be removed in a future
|
||
|
|
version.</p>
|
||
|
|
<p>Examples:</p>
|
||
|
|
<ul>
|
||
|
|
<li><code>./my-package</code></li>
|
||
|
|
<li><code>/opt/npm/my-package</code></li>
|
||
|
|
</ul>
|
||
|
|
<h3 id="tarballs">Tarballs</h3>
|
||
|
|
<ul>
|
||
|
|
<li><code><tarball file></code></li>
|
||
|
|
<li><code><tarball url></code></li>
|
||
|
|
</ul>
|
||
|
|
<p>Examples:</p>
|
||
|
|
<ul>
|
||
|
|
<li><code>./my-package.tgz</code></li>
|
||
|
|
<li><code>https://registry.npmjs.org/semver/-/semver-1.0.0.tgz</code></li>
|
||
|
|
</ul>
|
||
|
|
<p>Refers to a package in a tarball format, either on the local filesystem
|
||
|
|
or remotely via url. This is the format that packages exist in when
|
||
|
|
uploaded to a registry.</p>
|
||
|
|
<h3 id="git-urls">git urls</h3>
|
||
|
|
<ul>
|
||
|
|
<li><code><git:// url></code></li>
|
||
|
|
<li><code><github username>/<github project></code></li>
|
||
|
|
</ul>
|
||
|
|
<p>Refers to a package in a git repo. This can be a full git url, git
|
||
|
|
shorthand, or a username/package on GitHub. You can specify a
|
||
|
|
git tag, branch, or other git ref by appending <code>#ref</code>.</p>
|
||
|
|
<p>Examples:</p>
|
||
|
|
<ul>
|
||
|
|
<li><code>https://github.com/npm/cli.git</code></li>
|
||
|
|
<li><code>git@github.com:npm/cli.git</code></li>
|
||
|
|
<li><code>git+ssh://git@github.com/npm/cli#v6.0.0</code></li>
|
||
|
|
<li><code>github:npm/cli#HEAD</code></li>
|
||
|
|
<li><code>npm/cli#c12ea07</code></li>
