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。
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。
正如这个答案所解释的,//键是保留的,所以它可以常规地用于注释。//注释的问题是它不实用,因为它不能被多次使用。在包上删除重复的密钥。Json自动更新:
"//": "this comment about dependencies stays",
"dependencies": {}
"//": "this comment disappears",
"devDependencies": {}
另一个问题是// comment不能在依赖项和devDependencies中使用,因为它被视为常规依赖项:
"dependencies": {
"//": "comment"
}
npm犯错!代码EINVALIDPACKAGENAME
npm犯错!无效的包名“//”:名称只能包含url友好
字符
在NPM中工作的一个变通方法,而不是Yarn,是使用一个非字符串值:
"dependencies": {
"foo": ["unused package"],
}
一个在NPM和Yarn中工作的变通方法是添加一个注释作为语义版本控制的一部分:
"dependencies": {
"bar": "^2",
"foo": "^2 || should be removed in 1.x release"
}
注意,如果OR之前的第一部分不匹配,则可以解析来自注释的版本,例如1.x。
需要注释但没有安装的包应该移动到另一个键,例如dependencies //:
"dependencies //": {
"baz": "unused package",
}
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"
}
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。
