TypeScript

Question

对于我正在导入的一些模块，我最终修改了它们的声明文件以使它们工作。我不确定我是不是做错了，或者这些模块的类型是否恰好有问题。

index.tsx

import * as React from "react";
import * as moment from "moment";
import BigCalendar from "react-big-calendar";
import ReactModal from "react-modal";

react 和 moment 导入正常。问题在于 react-big-calendar 和 react-modal。这基本上是我为 react-modal:

经历的过程

我安装了@types/react-modal.

node_modules/@types/react-modal/index.d.ts（缩写）

// Type definitions for react-modal 1.6
// Project: https://github.com/reactjs/react-modal
// Definitions by: Rajab Shakirov <https://github.com/radziksh>, Drew Noakes <https://github.com/drewnoakes>, Thomas B Homburg <https://github.com/homburg>
// Definitions: https://github.com/DefinitelyTyped/DefinitelyTyped
// TypeScript Version: 2.3

import * as React from "react";

export as namespace ReactModal;

export = ReactModal;

declare namespace ReactModal {
    interface Props {
        ...
    }
}

declare class ReactModal extends React.Component<ReactModal.Props> {
    ...
}

我试过 import ReactModal from "react-modal" 结果是 Module '...' has no default export.

我试过了import { ReactModal } from "react-modal" 这给了我 Module '...' has no exported member 'ReactModal'.

我试过 import * asReactModal from "react-modal" 编译，但在运行时给了我 Warning: React.createElement: type is invalid -- expected a string (for built-in components) or a class/function (for composite components) but got: object。

最后我只是将声明文件更改为：

import * as React from "react";

export as namespace ReactModal;

declare namespace ReactModal {
    interface Props {
        ...
    }
}

export default class ReactModal extends React.Component<ReactModal.Props> {
    ...
}

然后我就可以使用 import ReactModal from "react-modal"，而且成功了。

使用 react-big-calendar 我刚刚卸载了 @types/react-big-calendar，现在有了自己的输入法。当然，其他人正在为这些包使用这些声明文件而没有这些麻烦。任何指导将不胜感激。

我认为 react-modal/index.d.ts has a bug and you (or I) should submit a pull request. If I interpret their react-modal-tests.tsx 正确，他们使用 import * as ReactModal from 'react-modal'; 导入它，编译但不运行。我的印象是他们的测试只能编译。

我在 node_packages/@types 中找到了如何在不修改文件的情况下让它工作的方法。

将这些行添加到 tsconfig 文件的 compilerOptions 部分： "baseUrl": "src/types", "typeRoots": [ "./src/types", "./node_modules/@types" ]

然后将修改后的react-modal/index.d.ts放入src/types/react-modal/index.d.ts。然后打字稿编译器应该在那里找到它。我只是将 node_modules/@types/react-modal 的内容复制到 src/types/react-modal 并进行了更改。
