我有一个使用流进行类型检查的 React 组件的 npm 包。
对于我的组件的用户来说，访问我的流类型会很有用。然而，目前我正在使用 Babel 编译我的代码，它会去除所有类型信息。
我的项目结构如下:
|
|- flowdecls
myTypes.js
| -components
- Component1
Component1.js
| - lib
- Component1.js (compiled using Babel)
- Component1.js.flow (created using flow-copy-source)
例如我在
myTypes.js 中的一种类型是declare type DataItemIconType = {
iconElement: React$Element<React$ElementType>,
color?: string,
hoverColor?: string
}
我将在
Component1 中使用.例如 Component1 的 Prop 之一将会iconList : Array<DataItemIconType>
我已经将我的 React 组件库的多个版本发布为没有 Flow 的 npm 包，并且我的组件正在被广泛使用。但是我真的很想提供流量支持。
在我最近尝试使用 流复制源 如本文 (Authoring and publishing JavaScript modules with Flow) 中所述，但我的库的用户仍然无法访问我的类型。
我将如何制作
DataItemIconType 之类的类型对使用 Component1 的人可用在我的图书馆里？包.json

最佳答案
Flow 会自动寻找相邻的 module.js.flow declarations files ，如果存在。
例如，如果您有一个指向 dist/index.js 的主字段。 ，然后添加 dist/index.js.flow到您的包的输出将由用户的语言服务器接收。
