<p>I'm trying to load svg and png files as paths from the /static/ directory in order to dynamically use them as favicons. </p> <p>I configured everything according to the documentation: </p> <pre class="brush:php;toolbar:false;">./src/model/view/<SomeView.ts> ./static/<SomeFile.png|svg> ./src/custom.d.ts ./tsconfig.json ./webpack.config.js ./package.json</pre> <p>Sample View <code>BrowserView.ts</code></p> <pre class="brush:php;toolbar:false;">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; }</pre> <p>Custom type declaration <code>custom.d.ts</code></p> <pre class="brush:php;toolbar:false;">declare module "*.svg" { const path: string; export = path; } declare module "*.png" { const path: string; export = path; }</pre> <p><code>tsconfig.json</code></p> <pre class="brush:php;toolbar:false;">{ "compilerOptions" : { "esModuleInterop" : true, "experimentalDecorators" : true, "jsx" : "react", "moduleResolution" : "node", "strict" : true, "target" : "ES6" }, "include" : [ "./src/model/view/*", "./src/custom.d.ts" ] }</pre> <p><code>webpack.config.js</code></p> <pre class="brush:php;toolbar:false;">module.exports = { module: { rules: [ { test: /\.(jpe?g|png|svg)$/, use: "url-loader" } ] } };</pre> <p><code>package.json</code> contains <code>webpack</code> and <code>url-loader</code>.</p> <p>但是我仍然遇到了这个错误:</p> <pre class="brush:php;toolbar:false;">ERROR in ./static/favicon_browser-32x32.png 1:0 Module parse failed: Unexpected character '�' (1:0) You may need an appropriate loader to handle this file type, currently no loaders are configured to process this file.

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

Here is the link used by webpack 5 images https://webpack.js.org/guides/asset-management/#loading-images
