我试图按照here
中的说明在Web Worker中运行我的angular6 Web应用程序由于angular6中缺少ng eject
,因此我使用this创建了一个自定义的webpack配置文件。
workerLoader.ts
import './polyfills.ts';
import '@angular/core';
import '@angular/common';
import { platformWorkerAppDynamic } from '../node_modules/@angular/platform-webworker-dynamic';
import { AppModule } from './app/app.module';
platformWorkerAppDynamic().bootstrapModule(AppModule);
main.ts
import { enableProdMode } from '@angular/core';
import { bootstrapWorkerUi,WORKER_UI_LOCATION_PROVIDERS } from '@angular/platform-webworker';
import { AppModule } from './app/app.module';
import { environment } from './environments/environment';
if (environment.production) {
enableProdMode();
}
bootstrapWorkerUi('webworker.chunk.js',WORKER_UI_LOCATION_PROVIDERS);
app.module.ts
import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { AppComponent } from './app.component';
import { MapComponent } from './map/map.component';
import {
WorkerAppModule,
WORKER_APP_LOCATION_PROVIDERS,
WORKER_UI_LOCATION_PROVIDERS
} from '@angular/platform-webworker';
import { APP_BASE_HREF } from '@angular/common'
@NgModule({
declarations: [
AppComponent,
// some components
],
imports: [
BrowserModule,
//some imports
WorkerAppModule,
],
providers: [
{
provide: APP_BASE_HREF,
useValue: '/'
},
WORKER_APP_LOCATION_PROVIDERS
],
bootstrap: [AppComponent]
})
export class AppModule { }
webpack.config.js
const webpack = require('webpack');
const path = require('path');
const { AotPlugin } = require('@ngtools/webpack');
module.exports = {
"entry": {
"main": [
"./src/main.ts",
],
"polyfills": [
"./src/polyfills.ts"
],
"styles": [
"./src/styles.css"
],
"webworker": [
"./src/workerLoader.ts"
]
}
,
"output": {
"path": path.join(process.cwd(), "dist"),
"filename": "[name].bundle.js",
"chunkFilename": "[id].chunk.js"
},
optimization: {
splitChunks: {
cacheGroups: {
commons: {
test: /[\\/]node_modules[\\/]/,
name: 'vendor',
chunks: 'all'
}
}
}
},
}
问题是进入浏览器后,出现错误webworker.chunk.js:1 Uncaught ReferenceError: window is not defined
,造成此错误的行是
(window["webpackJsonp"] = window["webpackJsonp"] || []).push([["webworker"],{
我找到相同的question,但对我不起作用。
如何解决问题?
更新:
我的问题被标记为可能重复,但我自己提到了这个问题,并强调这对我不起作用。
更新:
AFAIK,Web工作人员无法访问诸如window
之类的全局变量,并且由于某种原因要在Web Worker中访问window
,因此该错误有点奇怪。我认为webpack配置文件中的配置错误是错误的原因。

答案 0 :(得分:0)
我遇到了同样的错误,我通过在angular.json中的customWebpackConfig中添加以下选项来解决了这个问题:
"mergeStrategies": {"optimization":"replace"}
我希望对您有帮助
