Webpack並非所有源地圖都顯示打字稿

Question

因此，我有一個結構如下的項目：

Root
|   index.html
|   package.json
|   tree.txt
|   tsconfig.json
|   webpack.config.js
|   
+---.vscode
|       settings.json
|       tasks.json
|       
+---app
|   |   main.js
|   |   main.js.map
|   |   main.ts
|   |   test.js
|   |   test.js.map
|   |   test.ts
|   |   
|   +---components
|   |       app.component.js
|   |       app.component.js.map
|   |       app.component.ts
|   |       
|   \---modules
|           app.module.js
|           app.module.js.map
|           app.module.ts
|           
\---node_modules
    |
    *SNIP*

我的問題是，只有我的main.ts源映射在chrome開發工具中顯示為實際的打字稿，app.module，app.component和test顯示為已編譯的javascript。

我設法找到的有關Webpack打字稿的任何其他問題都是babel加載程序特定的，放置斷點或源映射根本沒有生成的問題。

我的tsconfig：

{
    "compilerOptions": {
        "target": "es5",
        "module": "commonjs",
        "moduleResolution": "node",
        "sourceMap": true,
        "watch": true,
        "compileOnSave": true,
        "emitDecoratorMetadata": true,
        "experimentalDecorators": true,
        "removeComments": false,
        "noImplicitAny": false
    },
    "exclude": [
        "node_modules",
        "typings/browser",
        "typings/browser.d.ts"
    ],
    "atom": {
        "rewriteTsconfig": false
    },
    "typeRoots": [
        "./node_modules/@types"
    ],
    "types": [
        "core-js"
    ]
}

我的webpack.config.js：

const config = {
    entry: {
        app: "./app/main.ts"
    },
    output: {
        filename: "./bundle.js",
        path: "./"
    },
    devtool: "source-map",
    module: {
        loaders: [
            {
                test: /\.ts$/,
                loaders: ["awesome-typescript-loader", "angular2-template-loader"]
            }
        ]
    },
    resolve: {
        extentions: ["", ".ts", ".js"]
    }
}

module.exports = config;

適用於main.ts的Chrome開發工具輸出：

import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { AppModule } from './modules/app.module';
import { test } from "./test";
const platform = platformBrowserDynamic();
platform.bootstrapModule(AppModule);
alert(test.msg)


// WEBPACK FOOTER //
// ./~/angular2-template-loader!./app/main.ts

適用於test.js的Chrome開發工具輸出：

"use strict";
var test = (function () {
    function test() {
    }
    test.msg = "test";
    return test;
}());
exports.test = test;
//# sourceMappingURL=test.js.map


//////////////////
// WEBPACK FOOTER
// ./app/test.js
// module id = 25
// module chunks = 0

所有單獨的.map文件源均指向腳本的ts版本。

webpack-dev-server命令輸出：

webpack: bundle is now VALID.

我注意到它正在[23-24]上構建js文件，但是我不知道為什么，另外，僅運行webpack --debug會生成bundle.js.map文件，該文件的來源也指向js文件。

這個問題困擾我已經有一段時間了，所以如果這很簡單，我深表歉意。

謝謝你的幫助！

更新：

問題可能是我在將ts打包之前將其編譯了嗎？ 我嘗試在沒有編譯文件的情況下運行webpack，但是現在找不到我的ts文件：

./app/main.ts
Module not found: Error: Cannot resolve 'file' or 'directory' ./modules/app.module in C:\--\app

  C:\--\app\modules\app.module doesn't exist

為什么不解析我的.ts文件？

Answer 1

找到了問題。

不幸的是，在我的package.config “擴展名”應該是“擴展名” 。

Answer 2

如您所說，該錯誤位於webpack.config.js 。 從Webpack 2開始，當您擁有無效的配置對象時，它會顯示一條錯誤消息，因此升級Webpack版本將有助於您將來避免這些問題。

如果您不想升級Webpack，則可以使用此軟件包為您自動驗證您的配置： https : //github.com/js-dxtools/webpack-validator 。
