依赖选择器查询

选择 CLI 版本:

概要

Synopsis

npm query <selector>

描述

Description

npm query 命令允许使用 css 选择器来检索依赖对象数组。

The npm query command allows for usage of css selectors in order to retrieve an array of dependency objects.

管道 npm 查询到其他命令

Piping npm query to other commands

# find all dependencies with postinstall scripts & uninstall them
npm query ":attr(scripts, [postinstall])" | jq 'map(.name)|join("\n")' -r | xargs -I {} npm uninstall {}
# find all git dependencies & explain who requires them
npm query ":type(git)" | jq 'map(.name)' | xargs -I {} npm why {}

仅包锁定模式

Package lock only mode

如果启用了 package-lock-only,则仅加载包锁(或收缩封装)中的信息。这意味着依赖的 package.json 文件中的信息将不会包含在结果集中(例如描述、主页、引擎)。

If package-lock-only is enabled, only the information in the package lock (or shrinkwrap) is loaded. This means that information from the package.json files of your dependencies will not be included in the result set (e.g. description, homepage, engines).

配置

Configuration

global

  • 默认值:false

    Default: false

  • 类型:布尔值

    Type: Boolean

在 "global" 模式下运行,以便将包安装到 prefix 文件夹而不是当前工作目录。有关行为差异的更多信息,请参见 文件夹

Operates in "global" mode, so that packages are installed into the prefix folder instead of the current working directory. See folders for more on the differences in behavior.

  • 包安装到 {prefix}/lib/node_modules 文件夹,而不是当前工作目录。

    packages are installed into the {prefix}/lib/node_modules folder, instead of the current working directory.

  • bin 文件链接到 {prefix}/bin

    bin files are linked to {prefix}/bin

  • 手册页链接到 {prefix}/share/man

    man pages are linked to {prefix}/share/man

workspace

  • 默认值:

    Default:

  • 类型:字符串(可以设置多次)

    Type: String (can be set multiple times)

启用在当前项目的已配置工作区的上下文中运行命令,同时通过仅运行此配置选项定义的工作区进行过滤。

Enable running a command in the context of the configured workspaces of the current project while filtering by running only the workspaces defined by this configuration option.

workspace 配置的有效值为:

Valid values for the workspace config are either:

  • 工作区名称

    Workspace names

  • 工作区目录的路径

    Path to a workspace directory

  • 父工作区目录的路径(将导致选择该文件夹中的所有工作区)

    Path to a parent workspace directory (will result in selecting all workspaces within that folder)

npm init 命令设置时,可以将其设置为尚不存在的工作区的文件夹,以创建文件夹并将其设置为项目中的全新工作区。

When set for the npm init command, this may be set to the folder of a workspace which does not yet exist, to create the folder and set it up as a brand new workspace within the project.

此值不会导出到子进程的环境中。

This value is not exported to the environment for child processes.

workspaces

  • 默认值:null

    Default: null

  • 类型:空值或布尔值

    Type: null or Boolean

设置为 true 可在所有已配置工作区的上下文中运行该命令。

Set to true to run the command in the context of all configured workspaces.

显式将此设置为 false 将导致像 install 这样的命令完全忽略工作区。未明确设置时:

Explicitly setting this to false will cause commands like install to ignore workspaces altogether. When not set explicitly:

  • node_modules 树上运行的命令(安装、更新等)会将工作区链接到 node_modules 文件夹。* 执行其他操作(测试、执行、发布等)的命令将在根项目上运行,除非在 workspace 配置中指定了一个或多个工作区。

    Commands that operate on the node_modules tree (install, update, etc.) will link workspaces into the node_modules folder. - Commands that do other things (test, exec, publish, etc.) will operate on the root project, unless one or more workspaces are specified in the workspace config.

此值不会导出到子进程的环境中。

This value is not exported to the environment for child processes.

include-workspace-root

  • 默认值:false

    Default: false

  • 类型:布尔值

    Type: Boolean

为命令启用工作区时包括工作区根。

Include the workspace root when workspaces are enabled for a command.

当为 false 时,通过 workspace 配置指定单个工作区,或通过 workspaces 标志指定所有工作区,将导致 npm 仅在指定的工作区上运行,而不是在根项目上运行。

When false, specifying individual workspaces via the workspace config, or all workspaces via the workspaces flag, will cause npm to operate only on the specified workspaces, and not on the root project.

此值不会导出到子进程的环境中。

This value is not exported to the environment for child processes.

package-lock-only

  • 默认值:false

    Default: false

  • 类型:布尔值

    Type: Boolean

如果设置为 true,当前操作将只使用 package-lock.json,忽略 node_modules

If set to true, the current operation will only use the package-lock.json, ignoring node_modules.

对于 update,这意味着只会更新 package-lock.json,而不是检查 node_modules 并下载依赖。

For update this means only the package-lock.json will be updated, instead of checking node_modules and downloading dependencies.

对于 list,这意味着输出将基于 package-lock.json 描述的树,而不是 node_modules 的内容。

For list this means the output will be based on the tree described by the package-lock.json, rather than the contents of node_modules.
