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"
}
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。

在浪费了一个小时的复杂和俗套的解决方案后,我找到了注释package.json中庞大的依赖项部分的简单而有效的解决方案。就像这样:
{
"name": "package name",
"version": "1.0",
"description": "package description",
"scripts": {
"start": "npm install && node server.js"
},
"scriptsComments": {
"start": "Runs development build on a local server configured by server.js"
},
"dependencies": {
"ajv": "^5.2.2"
},
"dependenciesComments": {
"ajv": "JSON-Schema Validator for validation of API data"
}
}
当以同样的方式排序时,现在我很容易在Git提交差异中或在编辑器中跟踪这些依赖/注释对,同时使用package.json文件。
不需要使用额外的工具,只需要简单有效的JSON。
