我一直在这样做:

{
  ...
  "scripts": {
    "about": "echo 'Say something about this project'",
    "about:clean": "echo 'Say something about the clean script'",
    "clean": "do something",
    "about:build": "echo 'Say something about building it'",
    "build": "do something",
    "about:watch": "echo 'Say something about how watch works'",
    "watch": "do something",
  }
  ...
}

这样，我既可以读取脚本本身的“伪注释”，也可以运行如下代码，在终端中查看某种帮助:

npm run about
npm run about:watch

如果你用的是纱线就更好了。

yarn about:clean

此外，正如@Dakota Jang在评论中指出的那样，你可以使用//之类的键来更清楚地表明这是一条评论。 像这样:

{
  ...
  "scripts": {
    "//clean": "echo 'Say something about the clean script'",
    "clean": "do something",
    "//build": "echo 'Say something about building it'",
    "build": "do something",
    "//watch": "echo 'Say something about how watch works'",
    "watch": "do something",
  }
  ...
}

然后运行:

npm run //build
# or
yarn //build

在终端中会有一个helper输出，在包中会有一个“comment”。Json也是。

因为大多数开发人员都熟悉基于标记/注释的文档，所以我开始使用的约定是类似的。来尝尝:

{
  "@comment dependencies": [
    "These are the comments for the `dependencies` section.",
    "The name of the section being commented is included in the key after the `@comment` 'annotation'/'tag' to ensure the keys are unique.",
    "That is, using just \"@comment\" would not be sufficient to keep keys unique if you need to add another comment at the same level.",
    "Because JSON doesn't allow a multi-line string or understand a line continuation operator/character, just use an array for each line of the comment.",
    "Since this is embedded in JSON, the keys should be unique.",
    "Otherwise JSON validators, such as ones built into IDEs, will complain.",
    "Or some tools, such as running `npm install something --save`, will rewrite the `package.json` file but with duplicate keys removed.",
    "",
    "@package react - Using an `@package` 'annotation` could be how you add comments specific to particular packages."
  ],
  "dependencies": {
    ...
  },
  "@comment scripts": {
    "build": "This comment is about the build script.",
    "start": [
      "This comment is about the `start` script.",
      "It is wrapped in an array to allow line formatting.",
      "When using npm, as opposed to yarn, to run the script, be sure to add ` -- ` before adding the options.",
      "",
      "@option {number} --port - The port the server should listen on."
    ],
    "test": "This comment is about the test script.",
  },
  "scripts": {
    "build": "...",
    "start": "...",
    "test": "..."
  }
}

注意:对于dependencies、devDependencies等部分，注释注释不能直接添加到配置对象中各个包依赖项的上面，因为npm期望键是npm包的名称。这就是@comment依赖的原因。

我喜欢在JSON中添加注释的注释/标记样式，因为@符号与普通声明不同。

年长的建议

以下是我之前的建议。它内联注释的脚本，但我已经意识到，这些注释显示为“命令”在一些工具(在VS Code > Explorer > NPM脚本部分)。最新的建议没有受到这个问题的影响，但是脚本注释不再位于同一位置。

{
  "@comment dependencies": [
    ...
  ],
  "dependencies": {
    ...
  },
  "scripts": {
    "@comment build": "This comment is about the build script.",
    "build": "...",

    "@comment start": [
      "This comment is about the `start` script.",
      "It is wrapped in an array to allow line formatting.",
      "When using npm, as opposed to yarn, to run the script, be sure to add ` -- ` before adding the options.",
      "",
      "@option {number} --port - The port the server should listen on."
    ],
    "start": "...",

    "@comment test": "This comment is about the test script.",
    "test": "..."
  }
}

注意:在某些情况下，例如在“scripts”对象中，一些编辑器/ ide可能会抱怨数组。在脚本上下文中，VS Code期望值为字符串——而不是数组。

由于重复的注释键被删除运行包。json工具(npm, yarn等)，我开始使用散列版本，允许更好地阅读多行和键，如:

"//": {
  "alpaca": "we use the bootstrap version",
  "eonasdan-bootstrap-datetimepicker": "instead of bootstrap-datetimepicker",
  "moment-with-locales": "is part of moment"
},

根据我的IDE作为根键，这是“有效的”，但在依赖关系中，它抱怨期望字符串值。

用于npm的包。我发现了两种方法(在阅读这段对话后):

  "devDependencies": {
    "del-comment": [
      "some-text"
    ],
    "del": "^5.1.0 ! inner comment",
    "envify-comment": [
      "some-text"
    ],
    "envify": "4.1.0 ! inner comment"
  }

但是在更新或重新安装带有“——save”或“——save-dev”的包时，会出现“^4.1.0 !”注释”中相应的地方将被删除。所有这些都将打破npm审计。

我做了一些你们可能会喜欢的事情:

这个//在名字里面意味着它是我的注释:

  "//":"Main and typings are used till ES5",
  "//main": "build/index",
  "//typings": "build/index",

以下是我对包内评论的看法。Json / bower.json:

我有文件package.json.js，其中包含一个脚本，导出实际的package.json。运行脚本将覆盖旧包。Json并告诉我它所做的更改，完美地帮助你跟踪NPM所做的自动更改。这样，我甚至可以通过编程方式定义我想要使用的包。
