我在react中使用typescript,需要为一个名为react-sticky
的第三方库提供类型。我不想发布typings模块,我只想编写类型并将它们包含在我的代码库中,但我遇到了麻烦。下面是设置
App.tsx
/// <reference path="./typings/index.d.ts" />
/// <reference path="./typings/react-sticky.d.ts" />
import * as React from "react"
import { Sticky, StickyContainer } from "react-sticky"
const App: React.StatelessComponent<{}> = () => {
return <StickyContainer>
<Sticky>
<h1>Hello World</h1>
</Sticky>
</StickyContainer>
}
/typings/react-sticky.d.ts
/// <reference path="./modules/react/index.d.ts" />
import * as React from "react"
declare module "react-sticky" {
export var StickyContainer: React.Component<{}, {}>
export interface StickyProps {
stickyStyle?: any
stickyClassName?: string
topOffset?: number
bottomOffset?: number
className?: string
style?: {}
onStickyStateChange?: () => void
isActive?: boolean
}
export var Sticky: React.Component<StickyProps, {}>
}
typings/index.d.ts
/// <reference path="modules/react-dom/index.d.ts" />
/// <reference path="modules/react/index.d.ts" />
/// <reference path="react-sticky.d.ts" />
我得到的错误如下
App.tsx(3,41): error TS2307: Cannot find module 'react-sticky'.
现在,我是Typescript的新手,这里很可能有多个错误,有人知道我需要做什么吗? 你就快成功了。由于这是您第一次声明模块'react-sticky', (<>在其他地方增加声明),因此您必须将import语句放在模块声明中。您的声明文件可能看起来像这样:
// custom_typings/react-sticky.d.ts
declare module "react-sticky" {
import * as React from "react"
var StickyContainer: React.ComponentClass<{}>
interface StickyProps {
stickyStyle?: any
stickyClassName?: string
topOffset?: number
bottomOffset?: number
className?: string
style?: {}
onStickyStateChange?: () => void
isActive?: boolean
}
var Sticky: React.ComponentClass<StickyProps>
}
有趣的事实:
- 你不需要在你的声明文件中添加导出
- 你不需要在任何地方添加
///
引用,只要你不把你的声明文件放在你的项目的根目录。
