"contributors" is an array of people. A "person" -is an object with a "name" field and optionally "url" and "email", like this:</p> -<pre><code>{ "name" : "Barney Rubble" -, "email" : "b@rubble.com" -, "url" : "http://barnyrubble.tumblr.com/" -}</code></pre><p>Or you can shorten that all into a single string, and npm will parse it for you:</p> -<pre><code>"Barney Rubble <b@rubble.com> (http://barnyrubble.tumblr.com/)"</code></pre><p>Both email and url are optional either way.</p> -<p>npm also sets a top-level "maintainers" field with your npm user info.</p> -<h2 id="files">files</h2> -<p>The optional <code>files</code> field is an array of file patterns that describes -the entries to be included when your package is installed as a -dependency. File patterns follow a similar syntax to <code>.gitignore</code>, but -reversed: including a file, directory, or glob pattern (<code>*</code>, <code>**/*</code>, and such) -will make it so that file is included in the tarball when it's packed. Omitting -the field will make it default to <code>["*"]</code>, which means it will include all files.</p> -<p>Some special files and directories are also included or excluded regardless of -whether they exist in the <code>files</code> array (see below).</p> -<p>You can also provide a <code>.npmignore</code> file in the root of your package or -in subdirectories, which will keep files from being included. At the -root of your package it will not override the "files" field, but in -subdirectories it will. The <code>.npmignore</code> file works just like a -<code>.gitignore</code>. If there is a <code>.gitignore</code> file, and <code>.npmignore</code> is -missing, <code>.gitignore</code>'s contents will be used instead.</p> -<p>Files included with the "package.json#files" field <em>cannot</em> be excluded -through <code>.npmignore</code> or <code>.gitignore</code>.</p> -<p>Certain files are always included, regardless of settings:</p> -<ul> -<li><code>package.json</code></li> -<li><code><a href="../../doc/README.html">README</a></code></li> -<li><code>CHANGES</code> / <code>CHANGELOG</code> / <code>HISTORY</code></li> -<li><code>LICENSE</code> / <code>LICENCE</code></li> -<li><code>NOTICE</code></li> -<li>The file in the "main" field</li> -</ul> -<p><code><a href="../../doc/README.html">README</a></code>, <code>CHANGES</code>, <code>LICENSE</code> & <code>NOTICE</code> can have any case and extension.</p> -<p>Conversely, some files are always ignored:</p> -<ul> -<li><code>.git</code></li> -<li><code>CVS</code></li> -<li><code>.svn</code></li> -<li><code>.hg</code></li> -<li><code>.lock-wscript</code></li> -<li><code>.wafpickle-N</code></li> -<li><code>.*.swp</code></li> -<li><code>.DS_Store</code></li> -<li><code>._*</code></li> -<li><code>npm-debug.log</code></li> -<li><code>.npmrc</code></li> -<li><code>node_modules</code></li> -<li><code>config.gypi</code></li> -<li><code>*.orig</code></li> -<li><code>package-lock.json</code> (use shrinkwrap instead)</li> -</ul> -<h2 id="main">main</h2> -<p>The main field is a module ID that is the primary entry point to your program. -That is, if your package is named <code>foo</code>, and a user installs it, and then does -<code>require("foo")</code>, then your main module's exports object will be returned.</p> -<p>This should be a module ID relative to the root of your package folder.</p> -<p>For most modules, it makes the most sense to have a main script and often not -much else.</p> -<h2 id="browser">browser</h2> -<p>If your module is meant to be used client-side the browser field should be -used instead of the main field. This is helpful to hint users that it might -rely on primitives that aren't available in Node.js modules. (e.g. <code>window</code>)</p> -<h2 id="bin">bin</h2> -<p>A lot of packages have one or more executable files that they'd like to -install into the PATH. npm makes this pretty easy (in fact, it uses this -feature to install the "npm" executable.)</p> -<p>To use this, supply a <code>bin</code> field in your package.json which is a map of -command name to local file name. On install, npm will symlink that file into -<code>prefix/bin</code> for global installs, or <code>./node_modules/.bin/</code> for local -installs.</p> -<p>For example, myapp could have this:</p> -<pre><code>{ "bin" : { "myapp" : "./cli.js" } }</code></pre><p>So, when you install myapp, it'll create a symlink from the <code>cli.js</code> script to -<code>/usr/local/bin/myapp</code>.</p> -<p>If you have a single executable, and its name should be the name -of the package, then you can just supply it as a string. For example:</p> -<pre><code>{ "name": "my-program" -, "version": "1.2.5" -, "bin": "./path/to/program" }</code></pre><p>would be the same as this:</p> -<pre><code>{ "name": "my-program" -, "version": "1.2.5" -, "bin" : { "my-program" : "./path/to/program" } }</code></pre><p>Please make sure that your file(s) referenced in <code>bin</code> starts with -<code>#!/usr/bin/env node</code>, otherwise the scripts are started without the node -executable!</p> -<h2 id="man">man</h2> -<p>Specify either a single file or an array of filenames to put in place for the -<code>man</code> program to find.</p> -<p>If only a single file is provided, then it's installed such that it is the -result from <code>man <pkgname></code>, regardless of its actual filename. For example:</p> -<pre><code>{ "name" : "foo" -, "version" : "1.2.3" -, "description" : "A packaged foo fooer for fooing foos" -, "main" : "foo.js" -, "man" : "./man/doc.1" -}</code></pre><p>would link the <code>./man/doc.1</code> file in such that it is the target for <code>man foo</code></p> -<p>If the filename doesn't start with the package name, then it's prefixed. -So, this:</p> -<pre><code>{ "name" : "foo" -, "version" : "1.2.3" -, "description" : "A packaged foo fooer for fooing foos" -, "main" : "foo.js" -, "man" : [ "./man/foo.1", "./man/bar.1" ] -}</code></pre><p>will create files to do <code>man foo</code> and <code>man foo-bar</code>.</p> -<p>Man files must end with a number, and optionally a <code>.gz</code> suffix if they are -compressed. The number dictates which man section the file is installed into.</p> -<pre><code>{ "name" : "foo" -, "version" : "1.2.3" -, "description" : "A packaged foo fooer for fooing foos" -, "main" : "foo.js" -, "man" : [ "./man/foo.1", "./man/foo.2" ] -}</code></pre><p>will create entries for <code>man foo</code> and <code>man 2 foo</code></p> -<h2 id="directories">directories</h2> -<p>The CommonJS <a href="http://wiki.commonjs.org/wiki/Packages/1.0">Packages</a> spec details a -few ways that you can indicate the structure of your package using a <code>directories</code> -object. If you look at <a href="https://registry.npmjs.org/npm/latest">npm's package.json</a>, -you'll see that it has directories for doc, lib, and man.</p> -<p>In the future, this information may be used in other creative ways.</p> -<h3 id="directorieslib">directories.lib</h3> -<p>Tell people where the bulk of your library is. Nothing special is done -with the lib folder in any way, but it's useful meta info.</p> -<h3 id="directoriesbin">directories.bin</h3> -<p>If you specify a <code>bin</code> directory in <code>directories.bin</code>, all the files in -that folder will be added.</p> -<p>Because of the way the <code>bin</code> directive works, specifying both a -<code>bin</code> path and setting <code>directories.bin</code> is an error. If you want to -specify individual files, use <code>bin</code>, and for all the files in an -existing <code>bin</code> directory, use <code>directories.bin</code>.</p> -<h3 id="directoriesman">directories.man</h3> -<p>A folder that is full of man pages. Sugar to generate a "man" array by -walking the folder.</p> -<h3 id="directoriesdoc">directories.doc</h3> -<p>Put markdown files in here. Eventually, these will be displayed nicely, -maybe, someday.</p> -<h3 id="directoriesexample">directories.example</h3> -<p>Put example scripts in here. Someday, it might be exposed in some clever way.</p> -<h3 id="directoriestest">directories.test</h3> -<p>Put your tests in here. It is currently not exposed, but it might be in the -future.</p> -<h2 id="repository">repository</h2> -<p>Specify the place where your code lives. This is helpful for people who -want to contribute. If the git repo is on GitHub, then the <code>npm docs</code> -command will be able to find you.</p> -<p>Do it like this:</p> -<pre><code>"repository": { - "type" : "git", - "url" : "https://github.com/npm/cli.git" -} - -"repository": { - "type" : "svn", - "url" : "https://v8.googlecode.com/svn/trunk/" -}</code></pre><p>The URL should be a publicly available (perhaps read-only) url that can be handed -directly to a VCS program without any modification. It should not be a url to an -html project page that you put in your browser. It's for computers.</p> -<p>For GitHub, GitHub gist, Bitbucket, or GitLab repositories you can use the same -shortcut syntax you use for <code>npm install</code>:</p> -<pre><code>"repository": "npm/npm" - -"repository": "github:user/repo" - -"repository": "gist:11081aaa281" - -"repository": "bitbucket:user/repo" - -"repository": "gitlab:user/repo"</code></pre><h2 id="scripts">scripts</h2> -<p>The "scripts" property is a dictionary containing script commands that are run -at various times in the lifecycle of your package. The key is the lifecycle -event, and the value is the command to run at that point.</p> -<p>See <code><a href="../misc/npm-scripts.html">npm-scripts(7)</a></code> to find out more about writing package scripts.</p> -<h2 id="config">config</h2> -<p>A "config" object can be used to set configuration parameters used in package -scripts that persist across upgrades. For instance, if a package had the -following:</p> -<pre><code>{ "name" : "foo" -, "config" : { "port" : "8080" } }</code></pre><p>and then had a "start" command that then referenced the -<code>npm_package_config_port</code> environment variable, then the user could -override that by doing <code>npm config set foo:port 8001</code>.</p> -<p>See <code><a href="../misc/npm-config.html">npm-config(7)</a></code> and <code><a href="../misc/npm-scripts.html">npm-scripts(7)</a></code> for more on package -configs.</p> -<h2 id="dependencies">dependencies</h2> -<p>Dependencies are specified in a simple object that maps a package name to a -version range. The version range is a string which has one or more -space-separated descriptors. Dependencies can also be identified with a -tarball or git URL.</p> -<p><strong>Please do not put test harnesses or transpilers in your -<code>dependencies</code> object.</strong> See <code>devDependencies</code>, below.</p> -<p>See <a href="../misc/semver.html">semver(7)</a> for more details about specifying version ranges.</p> -<ul> -<li><code>version</code> Must match <code>version</code> exactly</li> -<li><code>>version</code> Must be greater than <code>version</code></li> -<li><code>>=version</code> etc</li> -<li><code><version</code></li> -<li><code><=version</code></li> -<li><code>~version</code> "Approximately equivalent to version" See <a href="../misc/semver.html">semver(7)</a></li> -<li><code>^version</code> "Compatible with version" See <a href="../misc/semver.html">semver(7)</a></li> -<li><code>1.2.x</code> 1.2.0, 1.2.1, etc., but not 1.3.0</li> -<li><code>http://...</code> See 'URLs as Dependencies' below</li> -<li><code>*</code> Matches any version</li> -<li><code>""</code> (just an empty string) Same as <code>*</code></li> -<li><code>version1 - version2</code> Same as <code>>=version1 <=version2</code>.</li> -<li><code>range1 || range2</code> Passes if either range1 or range2 are satisfied.</li> -<li><code>git...</code> See 'Git URLs as Dependencies' below</li> -<li><code>user/repo</code> See 'GitHub URLs' below</li> -<li><code>tag</code> A specific version tagged and published as <code>tag</code> See <code><a href="../cli/npm-dist-tag.html">npm-dist-tag(1)</a></code></li> -<li><code>path/path/path</code> See <a href="#local-paths">Local Paths</a> below</li> -</ul> -<p>For example, these are all valid:</p> -<pre><code>{ "dependencies" : - { "foo" : "1.0.0 - 2.9999.9999" - , "bar" : ">=1.0.2 <2.1.2" - , "baz" : ">1.0.2 <=2.3.4" - , "boo" : "2.0.1" - , "qux" : "<1.0.0 || >=2.3.1 <2.4.5 || >=2.5.2 <3.0.0" - , "asd" : "http://asdf.com/asdf.tar.gz" - , "til" : "~1.2" - , "elf" : "~1.2.3" - , "two" : "2.x" - , "thr" : "3.3.x" - , "lat" : "latest" - , "dyl" : "file:../dyl" - } -}</code></pre><h3 id="urls-as-dependencies">URLs as Dependencies</h3> -<p>You may specify a tarball URL in place of a version range.</p> -<p>This tarball will be downloaded and installed locally to your package at -install time.</p> -<h3 id="git-urls-as-dependencies">Git URLs as Dependencies</h3> -<p>Git urls are of the form:</p> -<pre><code><protocol>://[<user>[:<password>]@]<hostname>[:<port>][:][/]<path>[#<commit-ish> | #semver:<semver>]</code></pre><p><code><protocol></code> is one of <code>git</code>, <code>git+ssh</code>, <code>git+http</code>, <code>git+https</code>, or -<code>git+file</code>.</p> -<p>If <code>#<commit-ish></code> is provided, it will be used to clone exactly that -commit. If the commit-ish has the format <code>#semver:<semver></code>, <code><semver></code> can -be any valid semver range or exact version, and npm will look for any tags -or refs matching that range in the remote repository, much as it would for a -registry dependency. If neither <code>#<commit-ish></code> or <code>#semver:<semver></code> is -specified, then <code>master</code> is used.</p> -<p>Examples:</p> -<pre><code>git+ssh://git@github.com:npm/cli.git#v1.0.27 -git+ssh://git@github.com:npm/cli#semver:^5.0 -git+https://isaacs@github.com/npm/cli.git -git://github.com/npm/cli.git#v1.0.27</code></pre><h3 id="github-urls">GitHub URLs</h3> -<p>As of version 1.1.65, you can refer to GitHub urls as just "foo": -"user/foo-project". Just as with git URLs, a <code>commit-ish</code> suffix can be -included. For example:</p> -<pre><code>{ - "name": "foo", - "version": "0.0.0", - "dependencies": { - "express": "expressjs/express", - "mocha": "mochajs/mocha#4727d357ea", - "module": "user/repo#feature\/branch" - } -}</code></pre><h3 id="local-paths">Local Paths</h3> -<p>As of version 2.0.0 you can provide a path to a local directory that contains a -package. Local paths can be saved using <code>npm install -S</code> or -<code>npm install --save</code>, using any of these forms:</p> -<pre><code>../foo/bar -~/foo/bar -./foo/bar -/foo/bar</code></pre><p>in which case they will be normalized to a relative path and added to your -<code>package.json</code>. For example:</p> -<pre><code>{ - "name": "baz", - "dependencies": { - "bar": "file:../foo/bar" - } -}</code></pre><p>This feature is helpful for local offline development and creating -tests that require npm installing where you don't want to hit an -external server, but should not be used when publishing packages -to the public registry.</p> -<h2 id="devdependencies">devDependencies</h2> -<p>If someone is planning on downloading and using your module in their -program, then they probably don't want or need to download and build -the external test or documentation framework that you use.</p> -<p>In this case, it's best to map these additional items in a <code>devDependencies</code> -object.</p> -<p>These things will be installed when doing <code>npm link</code> or <code>npm install</code> -from the root of a package, and can be managed like any other npm -configuration param. See <code><a href="../misc/npm-config.html">npm-config(7)</a></code> for more on the topic.</p> -<p>For build steps that are not platform-specific, such as compiling -CoffeeScript or other languages to JavaScript, use the <code>prepare</code> -script to do this, and make the required package a devDependency.</p> -<p>For example:</p> -<pre><code>{ "name": "ethopia-waza", - "description": "a delightfully fruity coffee varietal", - "version": "1.2.3", - "devDependencies": { - "coffee-script": "~1.6.3" - }, - "scripts": { - "prepare": "coffee -o lib/ -c src/waza.coffee" - }, - "main": "lib/waza.js" -}</code></pre><p>The <code>prepare</code> script will be run before publishing, so that users -can consume the functionality without requiring them to compile it -themselves. In dev mode (ie, locally running <code>npm install</code>), it'll -run this script as well, so that you can test it easily.</p> -<h2 id="peerdependencies">peerDependencies</h2> -<p>In some cases, you want to express the compatibility of your package with a -host tool or library, while not necessarily doing a <code>require</code> of this host. -This is usually referred to as a <em>plugin</em>. Notably, your module may be exposing -a specific interface, expected and specified by the host documentation.</p> -<p>For example:</p> -<pre><code>{ - "name": "tea-latte", - "version": "1.3.5", - "peerDependencies": { - "tea": "2.x" - } -}</code></pre><p>This ensures your package <code>tea-latte</code> can be installed <em>along</em> with the second -major version of the host package <code>tea</code> only. <code>npm install tea-latte</code> could -possibly yield the following dependency graph:</p> -<pre><code>├── tea-latte@1.3.5 -└── tea@2.2.0</code></pre><p><strong>NOTE: npm versions 1 and 2 will automatically install <code>peerDependencies</code> if -they are not explicitly depended upon higher in the dependency tree. In the -next major version of npm (npm@3), this will no longer be the case. You will -receive a warning that the peerDependency is not installed instead.</strong> The -behavior in npms 1 & 2 was frequently confusing and could easily put you into -dependency hell, a situation that npm is designed to avoid as much as possible.</p> -<p>Trying to install another plugin with a conflicting requirement will cause an -error. For this reason, make sure your plugin requirement is as broad as -possible, and not to lock it down to specific patch versions.</p> -<p>Assuming the host complies with <a href="https://semver.org/">semver</a>, only changes in -the host package's major version will break your plugin. Thus, if you've worked -with every 1.x version of the host package, use <code>"^1.0"</code> or <code>"1.x"</code> to express -this. If you depend on features introduced in 1.5.2, use <code>">= 1.5.2 < 2"</code>.</p> -<h2 id="bundleddependencies">bundledDependencies</h2> -<p>This defines an array of package names that will be bundled when publishing -the package.</p> -<p>In cases where you need to preserve npm packages locally or have them -available through a single file download, you can bundle the packages in a -tarball file by specifying the package names in the <code>bundledDependencies</code> -array and executing <code>npm pack</code>.</p> -<p>For example:</p> -<p>If we define a package.json like this:</p> -<pre><code>{ - "name": "awesome-web-framework", - "version": "1.0.0", - "bundledDependencies": [ - "renderized", "super-streams" - ] -}</code></pre><p>we can obtain <code>awesome-web-framework-1.0.0.tgz</code> file by running <code>npm pack</code>. -This file contains the dependencies <code>renderized</code> and <code>super-streams</code> which -can be installed in a new project by executing <code>npm install -awesome-web-framework-1.0.0.tgz</code>.</p> -<p>If this is spelled <code>"bundleDependencies"</code>, then that is also honored.</p> -<h2 id="optionaldependencies">optionalDependencies</h2> -<p>If a dependency can be used, but you would like npm to proceed if it cannot be -found or fails to install, then you may put it in the <code>optionalDependencies</code> -object. This is a map of package name to version or url, just like the -<code>dependencies</code> object. The difference is that build failures do not cause -installation to fail.</p> -<p>It is still your program's responsibility to handle the lack of the -dependency. For example, something like this:</p> -<pre><code>try { - var foo = require('foo') - var fooVersion = require('foo/package.json').version -} catch (er) { - foo = null -} -if ( notGoodFooVersion(fooVersion) ) { - foo = null -} - -// .. then later in your program .. - -if (foo) { - foo.doFooThings() -}</code></pre><p>Entries in <code>optionalDependencies</code> will override entries of the same name in -<code>dependencies</code>, so it's usually best to only put in one place.</p> -<h2 id="engines">engines</h2> -<p>You can specify the version of node that your stuff works on:</p> -<pre><code>{ "engines" : { "node" : ">=0.10.3 <0.12" } }</code></pre><p>And, like with dependencies, if you don't specify the version (or if you -specify "*" as the version), then any version of node will do.</p> -<p>If you specify an "engines" field, then npm will require that "node" be -somewhere on that list. If "engines" is omitted, then npm will just assume -that it works on node.</p> -<p>You can also use the "engines" field to specify which versions of npm -are capable of properly installing your program. For example:</p> -<pre><code>{ "engines" : { "npm" : "~1.0.20" } }</code></pre><p>Unless the user has set the <code>engine-strict</code> config flag, this -field is advisory only and will only produce warnings when your package is installed as a dependency.</p> -<h2 id="enginestrict">engineStrict</h2> -<p><strong>This feature was removed in npm 3.0.0</strong></p> -<p>Prior to npm 3.0.0, this feature was used to treat this package as if the -user had set <code>engine-strict</code>. It is no longer used.</p> -<h2 id="os">os</h2> -<p>You can specify which operating systems your -module will run on:</p> -<pre><code>"os" : [ "darwin", "linux" ]</code></pre><p>You can also blacklist instead of whitelist operating systems, -just prepend the blacklisted os with a '!':</p> -<pre><code>"os" : [ "!win32" ]</code></pre><p>The host operating system is determined by <code>process.platform</code></p> -<p>It is allowed to both blacklist, and whitelist, although there isn't any -good reason to do this.</p> -<h2 id="cpu">cpu</h2> -<p>If your code only runs on certain cpu architectures, -you can specify which ones.</p> -<pre><code>"cpu" : [ "x64", "ia32" ]</code></pre><p>Like the <code>os</code> option, you can also blacklist architectures:</p> -<pre><code>"cpu" : [ "!arm", "!mips" ]</code></pre><p>The host architecture is determined by <code>process.arch</code></p> -<h2 id="preferglobal">preferGlobal</h2> -<p><strong>DEPRECATED</strong></p> -<p>This option used to trigger an npm warning, but it will no longer warn. It is -purely there for informational purposes. It is now recommended that you install -any binaries as local devDependencies wherever possible.</p> -<h2 id="private">private</h2> -<p>If you set <code>"private": true</code> in your package.json, then npm will refuse -to publish it.</p> -<p>This is a way to prevent accidental publication of private repositories. If -you would like to ensure that a given package is only ever published to a -specific registry (for example, an internal registry), then use the -<code>publishConfig</code> dictionary described below to override the <code>registry</code> config -param at publish-time.</p> -<h2 id="publishconfig">publishConfig</h2> -<p>This is a set of config values that will be used at publish-time. It's -especially handy if you want to set the tag, registry or access, so that -you can ensure that a given package is not tagged with "latest", published -to the global public registry or that a scoped module is private by default.</p> -<p>Any config values can be overridden, but only "tag", "registry" and "access" -probably matter for the purposes of publishing.</p> -<p>See <code><a href="../misc/npm-config.html">npm-config(7)</a></code> to see the list of config options that can be -overridden.</p> -<h2 id="default-values">DEFAULT VALUES</h2> -<p>npm will default some values based on package contents.</p> -<ul> -<li><p><code>"scripts": {"start": "node server.js"}</code></p> -<p>If there is a <code>server.js</code> file in the root of your package, then npm -will default the <code>start</code> command to <code>node server.js</code>.</p> -</li> -<li><p><code>"scripts":{"install": "node-gyp rebuild"}</code></p> -<p>If there is a <code>binding.gyp</code> file in the root of your package and you have not defined an <code>install</code> or <code>preinstall</code> script, npm will -default the <code>install</code> command to compile using node-gyp.</p> -</li> -<li><p><code>"contributors": [...]</code></p> -<p>If there is an <code>AUTHORS</code> file in the root of your package, npm will -treat each line as a <code>Name <email> (url)</code> format, where email and url -are optional. Lines which start with a <code>#</code> or are blank, will be -ignored.</p> -</li> -</ul> -<h2 id="see-also">SEE ALSO</h2> -<ul> -<li><a href="../misc/semver.html">semver(7)</a></li> -<li><a href="../cli/npm-init.html">npm-init(1)</a></li> -<li><a href="../cli/npm-version.html">npm-version(1)</a></li> -<li><a href="../cli/npm-config.html">npm-config(1)</a></li> -<li><a href="../misc/npm-config.html">npm-config(7)</a></li> -<li><a href="../cli/npm-help.html">npm-help(1)</a></li> -<li><a href="../cli/npm-install.html">npm-install(1)</a></li> -<li><a href="../cli/npm-publish.html">npm-publish(1)</a></li> -<li><a href="../cli/npm-uninstall.html">npm-uninstall(1)</a></li> -</ul> - -</div> - -<table border=0 cellspacing=0 cellpadding=0 id=npmlogo> -<tr><td style="width:180px;height:10px;background:rgb(237,127,127)" colspan=18> </td></tr> -<tr><td rowspan=4 style="width:10px;height:10px;background:rgb(237,127,127)"> </td><td style="width:40px;height:10px;background:#fff" colspan=4> </td><td style="width:10px;height:10px;background:rgb(237,127,127)" rowspan=4> </td><td style="width:40px;height:10px;background:#fff" colspan=4> </td><td rowspan=4 style="width:10px;height:10px;background:rgb(237,127,127)"> </td><td colspan=6 style="width:60px;height:10px;background:#fff"> </td><td style="width:10px;height:10px;background:rgb(237,127,127)" rowspan=4> </td></tr> -<tr><td colspan=2 style="width:20px;height:30px;background:#fff" rowspan=3> </td><td style="width:10px;height:10px;background:rgb(237,127,127)" rowspan=3> </td><td style="width:10px;height:10px;background:#fff" rowspan=3> </td><td style="width:20px;height:10px;background:#fff" rowspan=4 colspan=2> </td><td style="width:10px;height:20px;background:rgb(237,127,127)" rowspan=2> </td><td style="width:10px;height:10px;background:#fff" rowspan=3> </td><td style="width:20px;height:10px;background:#fff" rowspan=3 colspan=2> </td><td style="width:10px;height:10px;background:rgb(237,127,127)" rowspan=3> </td><td style="width:10px;height:10px;background:#fff" rowspan=3> </td><td style="width:10px;height:10px;background:rgb(237,127,127)" rowspan=3> </td></tr> -<tr><td style="width:10px;height:10px;background:#fff" rowspan=2> </td></tr> -<tr><td style="width:10px;height:10px;background:#fff"> </td></tr> -<tr><td style="width:60px;height:10px;background:rgb(237,127,127)" colspan=6> </td><td colspan=10 style="width:10px;height:10px;background:rgb(237,127,127)"> </td></tr> -<tr><td colspan=5 style="width:50px;height:10px;background:#fff"> </td><td style="width:40px;height:10px;background:rgb(237,127,127)" colspan=4> </td><td style="width:90px;height:10px;background:#fff" colspan=9> </td></tr> -</table> -<p id="footer">package.json — npm@6.7.0</p> - |
