打字稿图像导入 [英] Typescript image import

问题描述

我在这里找到了解决方案: Webpack&打字稿图像导入

I found a solution here: Webpack & Typescript image import

但是我对此有误:

[ts]
Types of property 'src' are incompatible.
  Type 'typeof import("*.png")' is not assignable to type 'string | undefined'.
    Type 'typeof import("*.png")' is not assignable to type 'string'.

我想我需要以某种方式强制导入，但无法弄清楚如何. 我在React中做到这一点.我看到src属性定义为string | undefined，这就是为什么弹出错误的原因.

I guess i need to cast import somehow, but cant figure out how. I am doing this in React. I saw that src attribute is defined as string | undefined, that is why error is popping.

这是代码:

import * as Logo from 'assets/images/logo.png';

HTML:

<img src={Logo} alt="" />

以及基于上述解决方案的定义:

And definition based on above mentioned solution:

declare module "*.png" {
  const value: string;
  export default value;
}

Tsconfig:

{
  "compilerOptions": {
    "baseUrl": "./",
    "jsx": "react",
    "lib": ["es5", "es6", "dom"],
    "module": "commonjs",
    "noImplicitAny": false,
    "outDir": "./dist/",
    "sourceMap": true,
    "strictNullChecks": true,
    "target": "es5",
    "typeRoots": [
      "custom_typings"
    ]
  },
  "include": ["./src/**/*.tsx"],
  "exclude": ["dist", "build", "node_modules"]
}

推荐答案

摆脱该错误的一种方法是通过如下修改d.ts文件:

One of the ways to get rid of that error is by modifying d.ts file as follows:

declare module "*.png"

删除

{
  const value: string;
  export default value;
}

或者您可以执行以下操作:

or alternatively you can do:

declare module "*.png" {
  const value: any;
  export default value;
}

更新

使用类型检查的最佳解决方案是:

The best solution with type-checking is:

declare module "*.png" {
   const value: any;
   export = value;
}
