reactjs - Webpack Code Splitting 'Loading chunk failed' 错误文件路径错误

Question

我正在将 React + Typescript 与 Webpack 一起使用，我正在尝试在实际需要时加载我的一些 React 组件。

问题是，当通过延迟加载请求 block 时，我收到以下错误:

Uncaught Error: Loading chunk 1 failed.(error: http://localhost:58988/1.chunk.js)at HTMLScriptElement.onScriptComplete (bootstrap:114)

这个chunk生成成功，没有任何错误，只是路径不对 - http://localhost:58988/1.chunk.js 应该是http://localhost:58988/dist/1.chunk.js

我也尝试过使用最新的 React.lazy 来延迟加载 React 组件，但我遇到了同样的问题。那么，有没有办法告诉编译器如何解析这些文件路径呢？

部分代码如下:

MyComponent.tsx

import * as React from "react";
import * as ES5Promise from "promise";

export class MyComponent extends React.Component<{}, {}> {
    constructor(props) {
        super(props);
    }

    private readonly onLoadModuleClickHandler = (): void => {
        import("./Button").then((module) => {
            console.log(module);
        });
    }

    render() {
        return (
            <div>
                <input type="button" value="Load another module" onClick={this.onLoadModuleClickHandler}/>
            </div>
        );
    }
}

tsconfig.json

{
  "compilerOptions": {
    "moduleResolution": "node",
    "noImplicitAny": false,
    "noEmitOnError": true,
    "module": "esnext",
    "removeComments": false,
    "sourceMap": false,
    "target": "es5",
    "jsx": "react",
    "noEmit": true,
    "importHelpers": true,
    "lib": ["dom", "es5", "es2015.promise"]
  },
  "exclude": [
    "node_modules",
    "wwwroot"
  ]
}

webpack.config.js

module.exports = {
    entry: {
        "app": "./src/App.tsx"
    },
    output: {
        path: path.resolve(__dirname, 'wwwroot/dist'),
        filename: "[name].bundle.js",
        chunkFilename: "[name].chunk.js"
    },
    module: {
        rules: [
            {
                test: /\.(ts|tsx)?$/,
                use: "awesome-typescript-loader",
                exclude: /node_modules/
            },
            {
                test: /\.(css|less)?$/,
                use: [{
                    loader: "style-loader"
                }, {
                    loader: "css-loader?modules&localIdentName=[local]--[hash:base64:5]"
                }, {
                    loader: "less-loader"
                }]
            },
        ]
    },
    resolve: {
        extensions: [".js", ".jsx", ".ts", ".tsx", ".css", ".less"]
    }
};

发生这种情况是因为默认情况下 output.publicPath 是 /。

只需更新 output.publicPath 以指向您想要的位置 => /dist/。
