Path to load png and svg files from static directory using React and TypeScript

Question

I'm trying to load svg and png files as paths from the /static/ directory in order to dynamically use them as favicons.

I configured everything according to the documentation:

./src/model/view/<SomeView.ts>
./static/<SomeFile.png|svg>
./src/custom.d.ts
./tsconfig.json
./webpack.config.js
./package.json

Sample View BrowserView.ts

import FaviconPng from "../../../static/favicon_browser-32x32.png";
import FaviconSvg from "../../../static/favicon-browser.svg";
import { View } from "./View";

export class BrowserView implements View {
  public readonly faviconPng = FaviconPng;
  public readonly faviconSvg = FaviconSvg;
}

Custom type declaration custom.d.ts

declare module "*.svg" {
  const path: string;
  export = path;
}

declare module "*.png" {
  const path: string;
  export = path;
}

tsconfig.json

{
  "compilerOptions" : {
    "esModuleInterop" : true,
    "experimentalDecorators" : true,
    "jsx" : "react",
    "moduleResolution" : "node",
    "strict" : true,
    "target" : "ES6"
  },
  "include" : [
    "./src/model/view/*",
    "./src/custom.d.ts"
  ]
}

webpack.config.js

module.exports = {
  module: {
    rules: [
      {
        test: /\.(jpe?g|png|svg)$/,
        use: "url-loader"
      }
    ]
  }
};

package.json contains webpack and url-loader.

但是我仍然遇到了这个错误：

ERROR in ./static/favicon_browser-32x32.png 1:0

我猜测它无法识别加载器配置，但我不确定我可以改变什么。

如何从该目录加载图像作为路径来更改网站图标？

private updateFavicon(view: View): void {
    // 通过id标签获取元素
    const favicon_svg: HTMLElement = document.getElementById("favicon_svg")!;
    const favicon_png: HTMLElement = document.getElementById("favicon_png")!;

    // 设置图标
    favicon_svg.setAttribute("href", view.faviconSvg);
    favicon_png.setAttribute("href", view.faviconPng);
  }

It is best to use relative paths, relative to your project It's difficult to answer since the webpack version is not specified.
