到目前为止，这里的大多数“黑客”都建议滥用JSON。但是，为什么不滥用底层脚本语言呢?

最初的反应是把描述放在右边，使用# add comments here来包装它;然而，这在Windows上不起作用，因为标志(例如，npm run myframework -- --myframework-flags)将被忽略。我改变了我的响应，使其适用于所有平台，并增加了一些缩进的可读性。

{
 "scripts": {
    "help": "       echo 'Display help information (this screen)';          npm run",
    "myframework": "echo 'Run myframework binary';                          myframework",
    "develop": "    echo 'Run in development mode (with terminal output)';  npm run myframework"
    "start": "      echo 'Start myFramework as a daemon';                   myframework start",
    "stop":  "      echo 'Stop the myFramework daemon';                     myframework stop"
    "test": "echo \"Error: no test specified\" && exit 1"
  }
}

这将:

Not break JSON compliance (or at least it's not a hack, and your IDE will not give you warnings for doing strange, dangerous stuff) Works cross platform (tested on macOS and Windows, assuming it would work just fine on Linux) Does not get in the way of running npm run myframework -- --help Will output meaningful info when running npm run (which is the actual command to run to get information about available scripts) Presents a more explicit help command (in case some developers are not aware that npm run presents such output) Will show both the commands and its description when running the command itself Is somewhat readable when just opening package.json (using less or your favorite IDE)

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"
}

免责声明:你可能不应该使用这个黑客。请看下面的评论。

下面是另一个在JSON中添加注释的技巧。自:

{"a": 1, "a": 2}

等于

{"a": 2}

你可以这样做:

{
  "devDependencies": "'mocha' not needed as should be globally installed",
  "devDependencies" :  {
    "should": "*"
  }
}

另一个黑客

我创建了一个脚本来读取文件包。Json作为句柄模板的上下文。

代码如下，以防有人发现这种方法有用:

const templateData = require('../package.json');
const Handlebars = require('handlebars');
const fs = require('fs-extra');
const outputPath = __dirname + '/../package-json-comments.md';
const srcTemplatePath = __dirname + '/package-json-comments/package-json-comments.hbs';

Handlebars.registerHelper('objlist', function() {
  // The first argument is an object, and the list is a set of keys for that obj
  const obj = arguments[0];
  const list = Array.prototype.slice.call(arguments, 1).slice(0,-1);

  const mdList = list.map(function(k) {
    return '* ' + k + ': ' + obj[k];
  });

  return new Handlebars.SafeString(mdList.join("\n"));
});

fs.readFile(srcTemplatePath, 'utf8', function(err, srcTemplate){
  if (err) throw err;
  const template = Handlebars.compile(srcTemplate);
  const content = template(templateData);

  fs.writeFile(outputPath, content, function(err) {
    if (err) throw err;
  });
});

句柄模板文件package-json-comments.hbs

### Dependency Comments
For package: {{ name }}: {{version}}

#### Current Core Packages
should be safe to update
{{{objlist dependencies
           "@material-ui/core"
           "@material-ui/icons"
           "@material-ui/styles"
}}}

#### Lagging Core Packages
breaks current code if updated
{{{objlist dependencies
           "amazon-cognito-identity-js"
}}}

#### Major version change
Not tested yet
{{{objlist dependencies
           "react-dev-utils"
           "react-redux"
           "react-router"
           "redux-localstorage-simple"

}}}

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。

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*。
