我有一个简单的包裹。json文件,我想添加一个评论。有办法做到这一点吗,或者有什么hack可以做到这一点吗?

{
  "name": "My Project",
  "version": "0.0.1",
  "private": true,
  "dependencies": {
    "express": "3.x",
    "mongoose": "3.x"
  },
  "devDependencies" :  {
    "should": "*"
    /* "mocha": "*" not needed as should be globally installed */
  }
}

上面的示例注释在npm崩溃时不起作用。我还尝试了// style注释。

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*。

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"

}}}

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

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。

我最终得到了这样一个脚本:

    "//-6c": "---------------------------------------------------------------",
    "precommit": "lint-staged",
    "prepush": "yarn run back:lint:check && yarn run front:lint:check"
  },

我在这里的目的不是澄清一行,只是在后台、前端、所有等脚本之间使用某种分隔符。

我不太喜欢1a、1b、1c、2a……但钥匙是不同的,我没有任何问题,像这样。

“脚本”中的命令是bash代码-我们可以注释bash:

"dedup": "yarn-deduplicate && yarn # TODO remove this on yarn/npm v2 because integrated"
