NPS(节点包脚本)为我解决了这个问题。它允许你把NPM脚本放到一个单独的JavaScript文件中，在那里你可以添加大量的注释和任何其他你需要的JavaScript逻辑。 https://www.npmjs.com/package/nps

来自我的一个项目的package-scripts.js示例

module.exports = {
  scripts: {
    // makes sure e2e webdrivers are up to date
    postinstall: 'nps webdriver-update',

    // run the webpack dev server and open it in browser on port 7000
    server: 'webpack-dev-server --inline --progress --port 7000 --open',

    // start webpack dev server with full reload on each change
    default: 'nps server',

    // start webpack dev server with hot module replacement
    hmr: 'nps server -- --hot',

    // generates icon font via a gulp task
    iconFont: 'gulp default --gulpfile src/deps/build-scripts/gulp-icon-font.js',

    // No longer used
    // copyFonts: 'copyfiles -f src/app/glb/font/webfonts/**/* dist/1-0-0/font'
  }
}

我只是做了一个本地安装npm安装nps -save-dev，并把它放在我的包。json脚本。

"scripts": {
    "start": "nps",
    "test": "nps test"
}

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。

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。

最近在Node.js邮件列表中讨论了这个问题。

根据创建npm的Isaac Schlueter的说法:

．.． "//"键永远不会被NPM用于任何目的，它是为注释保留的…如果想使用多行注释，可以使用数组或多个“//”键。

当使用你常用的工具(npm, yarn等)时，多个“//”键将被移除。这生存:

{ "//": [
  "first line",
  "second line" ] }

这将不复存在:

{ "//": "this is the first line of a comment",
  "//": "this is the second line of the comment" }

必须注意，"//"只能在包的根目录下使用。json对象。例如 ｛ “/ /”:“评论!” “依赖”:{…} ｝ 是有效的但是 ｛ “依赖”:{ “/ /”:“评论?” ｝ ｝ 是无效的。 ——@david_p评论

受这条线索的启发，下面是我们正在使用的:

{
  "//dependencies": {
    "crypto-exchange": "Unified exchange API"
  },
  "dependencies": {
    "crypto-exchange": "^2.3.3"
  },
  "//devDependencies": {
    "chai": "Assertions",
    "mocha": "Unit testing framwork",
    "sinon": "Spies, Stubs, Mocks",
    "supertest": "Test requests"
  },
  "devDependencies": {
    "chai": "^4.1.2",
    "mocha": "^4.0.1",
    "sinon": "^4.1.3",
    "supertest": "^3.0.0"
  }
}

我对JSON中没有注释的沮丧之处的看法。我创建了新节点，以它们所引用的节点命名，但以下划线作为前缀。这是不完美的，但功能。

{
  "name": "myapp",
  "version": "0.1.0",
  "private": true,
  "dependencies": {
    "react": "^16.3.2",
    "react-dom": "^16.3.2",
    "react-scripts": "1.1.4"
  },
  "scripts": {
    "__start": [
        "a note about how the start script works"
    ],
    "start": "react-scripts start",
    "build": "react-scripts build",
    "test": "react-scripts test --env=jsdom",
    "eject": "react-scripts eject"
  },
  "__proxy": [
    "A note about how proxy works",
    "multilines are easy enough to add"
  ],
  "proxy": "http://server.whatever.com:8000"
}
