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。

最新的Grunt任务如下: https://gist.github.com/MarZab/72fa6b85bc9e71de5991

总结一下这些答案:

添加一个名为//的顶级字段，其中包含一个注释字符串。这是可行的，但它很糟糕，因为你不能把评论放在他们正在评论的东西附近。 添加多个以//开头的顶级字段，例如包含注释字符串的//dependencies。这样更好，但仍然只允许您做顶级注释。不能注释单个依赖项。 在脚本中添加echo命令。这是可行的，但它很糟糕，因为您只能在脚本中使用它。

这些解决方案的可读性也都不是很好。它们增加了大量的视觉干扰，ide不会用语法将它们作为注释突出显示。

我认为唯一合理的解决方案是生成包。Json从另一个文件。最简单的方法是将JSON写成JavaScript，然后使用Node.js将其写入package.json。将该文件保存为package.json。chmod +x它，然后你可以运行它来生成你的package。json。

#!/usr/bin/env node

import { writeFileSync } from "fs";

const config = {
  // TODO: Think of better name.
  name: "foo",
  dependencies: {
    // Bar 2.0 does not work due to bug 12345.
    bar: "^1.2.0",
  },
  // Look at these beautify comments. Perfectly syntax highlighted, you
  // can put them anywhere and there no risk of some tool removing them.
};

writeFileSync("package.json", JSON.stringify({
    "//": "This file is \x40generated from package.json.mjs; do not edit.",
    ...config
  }, null, 2));

它使用//键来警告人们不要编辑它。\x40生成是故意的。它变成了@generated in package。Json，这意味着一些代码审查系统将在默认情况下崩溃该文件。

这是构建系统中的一个额外步骤，但它胜过这里的所有其他hack。

我有一个有趣的黑客想法。

创建一个适当的npm包名，作为文件包中的依赖项和devDependencies块的注释分隔符。Json，例如x----x----x

{
    "name": "app-name",
    "dependencies": {
        "x----x----x": "this is the first line of a comment",
        "babel-cli": "6.x.x",
        "babel-core": "6.x.x",
        "x----x----x": "this is the second line of a comment",
        "knex": "^0.11.1",
        "mocha": "1.20.1",
        "x----x----x": "*"
    }
}

注意:您必须在最后一个注释分隔行中添加一个有效的版本，如块中的*。

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。

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。

我喜欢这个:

  "scripts": {
    "⏬⏬⏬ Jenkins Build - in this order ⏬⏬⏬                                                                                                  ": "",
    "purge": "lerna run something",
    "clean:test": "lerna exec --ignore nanana"
}

在命令名中有额外的空格，所以在Visual Studio Code的NPM Scripts插件中，你有更好的外观。
