我正在逐渐将使用 React to TypeScript 的应用程序重写为 ReScript。我已经在 ReScript 中实现了几个组件,但这是第一个,我将ReactDOM.Style.t其用作组件的属性。

这是我最小化的组件代码:

@genType
@react.component
let make = (~sx: option<ReactDOM.Style.t>=?) => {
  <div></div>
}

ReScript 编译得很好(除了没有使用的警告sx,但我们可以忽略它)。

bs.js生成了以下内容,这似乎很好:

// Generated by ReScript, PLEASE EDIT WITH CARE

import * as React from "react";

function InhypedIcon(Props) {
  return React.createElement("div", undefined);
}

var make = InhypedIcon;

export {
  make ,

}
/* react Not a pure module */

以及导致问题的以下相应.gen.tsx文件:

/* TypeScript file generated from InhypedIcon.res by genType. */
/* eslint-disable import/first */


import * as React from 'react';

// @ts-ignore: Implicit any on import
import * as InhypedIconBS__Es6Import from './InhypedIcon.bs';
const InhypedIconBS: any = InhypedIconBS__Es6Import;

import type {Style_t as ReactDOM_Style_t} from '@rescript/react/src/ReactDOM.gen';

// tslint:disable-next-line:interface-over-type-literal
export type Props = { readonly sx?: ReactDOM_Style_t };

export const make: React.ComponentType<{ readonly sx?: ReactDOM_Style_t }> = InhypedIconBS.make;

这不编译,我收到 TypeScript 错误:

TypeScript error in /app/src/icons/InhypedIcon.gen.tsx(11,48):
Cannot find module '@rescript/react/src/ReactDOM.gen' or its corresponding type declarations.  TS2307

     9 | const InhypedIconBS: any = InhypedIconBS__Es6Import;
    10 |
  > 11 | import type {Style_t as ReactDOM_Style_t} from '@rescript/react/src/ReactDOM.gen';
       |                                                ^
    12 |
    13 | // tslint:disable-next-line:interface-over-type-literal
    14 | export type Props = { readonly sx?: ReactDOM_Style_t };

我明白,那个 TS 找不到rescript/react/src/ReactDOM.gen,但我真的不知道为什么。有什么想法可以解决这个问题吗?

我的包版本:

node: v16.6.2

"typescript": "^4.1.2"
"rescript": "^9.1.4"
"@rescript/react": "^0.10.3"

谢谢你。

这是因为 GenType 不附带响应的 rescript 绑定,所以如果您需要它,您必须自己键入它(参见导入类型的文档):

@genType.import(("react", "CSSProperties"))
type reactStyle = ReactDOM.Style.t

@genType
@react.component
let make = (~sx: option<reactStyle>=?) => {
  <div></div>
}

这应该有效。
