AngularFire 错误仅在 ng serve --prod 时发生

问题描述

我有一个 Angular 8 应用程序，使用 npm 包 Angular Firebase (https://github.com/angular/angularfire2)，当我使用 Angular CLI 命令构建应用程序时 ngbuild --prod 并部署到我的主机我收到以下 Chrome 浏览器控制台错误:

I have an Angular 8 app, using npm package Angular Firebase (https://github.com/angular/angularfire2) and when I build the app with the Angular CLI command ng build --prod and deploy to my hosting I get the following Chrome Browser Console error:

TypeError: Object(...)(...).auth is not a function

如果我改为使用命令 ng build --prod --optimization=false 进行构建，则不会发生错误.

If I instead build with the command ng build --prod --optimization=false the error does not occur.

将 Angular CLI ng 构建选项 optimization 设置为 true 会导致 AngularFire2 npm 包错误.

Something with Angular CLI ng build option optimization set to true is causing the AngularFire2 npm package error.

我不确定如何进一步调试此问题.这是我的 package.json 文件:

I am not sure how to debug this issue further. Here is my package.json file:

这里是我导入 AngularFire2 Lib 的地方:

And here is where I import the AngularFire2 Lib:

import { Injectable } from '@angular/core';
import { AngularFireAuth } from "@angular/fire/auth";
import { Observable } from 'rxjs';
import { tap, map, take } from 'rxjs/operators';
import { Router } from '@angular/router';
import { User, auth } from 'firebase/app';

@Injectable({
  providedIn: 'root'
})
export class AuthService {
  user: Observable<User>

  constructor(
    private firBase: AngularFireAuth,
    private router: Router // Inject Firebase auth service
  ) {
    this.user = this.firBase.authState;
  }

  isLoggedIn(redirectUrl: string, isLoggedInRedirect?: string): Observable<boolean> {
    console.log('AuthService.isLoggedIn'); return this.user.pipe(
      take(1),
      map(authState => !!authState),
      tap(authenticated => {
        if (!authenticated) {
          console.log('user not authenticated');
          this.router.navigate([redirectUrl]);
          return;
        }
        console.log('user Authenticated');
        if (isLoggedInRedirect) {
          this.router.navigate([isLoggedInRedirect]);
        }
      })
    );
  }

  getDisplayName(): string {
    return this.firBase.auth.currentUser.displayName;
  }

  // Sign up with email/password
  async signUp(email: string, password: string) {
    try {
      const result = await this.firBase.auth.createUserWithEmailAndPassword(email, password);
      console.log("successfully registered!");
      console.log(result.user);
    }
    catch (error) {
      console.error(error.message);
    }
  }

  // Sign in with email/password
  async signIn(email: string, password: string, rememberMe: boolean): Promise<string> {
    let session = 'session'; //only persist in the current session or tab, and will be cleared when the tab or window in which the user authenticated is closed

    if (rememberMe) {
      session = 'local'; //state will be persisted even when the browser window is closed or the activity
    }

    console.log('persistence type', session);
    try {
      const _ = await this.firBase.auth.setPersistence(session);
      const result = await this.firBase.auth.signInWithEmailAndPassword(email, password);
      console.log('signin success');
      return 'success';
    }
    catch (error) {
      console.error(error.message);
      return error.message;
    }
  }

  async signOut() {
    try {
      const _ = await this.firBase.auth.signOut();
      this.user = this.firBase.authState;
      console.log('signOut complete, currentUser', this.firBase.auth.currentUser);
    }
    catch (error) {
      console.error(error.message);
    }
  }

  async forgotPassword(email: string): Promise<string> {
    try {
      await this.firBase.auth.sendPasswordResetEmail(email);
      return 'Reset Email Sent';
    }
    catch (error) {
      console.error(error.message);
      return error.message;
    }
  }
}

这是我的 app.module:

And here is my app.module:

import { NgModule, ErrorHandler } from '@angular/core';
import { RouterModule } from '@angular/router';
import { BrowserModule, HAMMER_GESTURE_CONFIG } from '@angular/platform-browser';
import { BrowserAnimationsModule } from '@angular/platform-browser/animations';
import { GestureConfig } from '@angular/material';
import {
  PerfectScrollbarModule,
  PERFECT_SCROLLBAR_CONFIG,
  PerfectScrollbarConfigInterface
} from 'ngx-perfect-scrollbar';


import { InMemoryWebApiModule } from 'angular-in-memory-web-api';
import { InMemoryDataService } from './shared/inmemory-db/inmemory-db.service';

import { rootRouterConfig } from './app.routing';
import { SharedModule } from './shared/shared.module';
import { AppComponent } from './app.component';

import { HttpClient, HttpClientModule } from '@angular/common/http';
import { TranslateModule, TranslateLoader } from '@ngx-translate/core';
import { TranslateHttpLoader } from '@ngx-translate/http-loader';
import { ErrorHandlerService } from './shared/services/error-handler.service';
import { SessionsModule } from './views/sessions/sessions.module';

import { AngularFireModule } from '@angular/fire';
//import { AngularFirestoreModule } from '@angular/fire/firestore';
import { environment } from '../environments/environment';
import { StartComponent } from './start.component';

// AoT requires an exported function for factories
export function HttpLoaderFactory(httpClient: HttpClient) {
  return new TranslateHttpLoader(httpClient);
}

const DEFAULT_PERFECT_SCROLLBAR_CONFIG: PerfectScrollbarConfigInterface = {
  suppressScrollX: true
};

@NgModule({
  imports: [
    SessionsModule,
    BrowserModule,
    BrowserAnimationsModule,
    SharedModule,
    AngularFireModule.initializeApp(environment.firebase),
    //AngularFirestoreModule,
    HttpClientModule,
    PerfectScrollbarModule,
    TranslateModule.forRoot({
      loader: {
        provide: TranslateLoader,
        useFactory: HttpLoaderFactory,
        deps: [HttpClient]
      }
    }),
    InMemoryWebApiModule.forRoot(InMemoryDataService, { passThruUnknownUrl: true }),
    RouterModule.forRoot(rootRouterConfig, { useHash: true, enableTracing: false })
  ],
  declarations: [AppComponent, StartComponent],
  providers: [
    { provide: ErrorHandler, useClass: ErrorHandlerService },
    { provide: HAMMER_GESTURE_CONFIG, useClass: GestureConfig },
    { provide: PERFECT_SCROLLBAR_CONFIG, useValue: DEFAULT_PERFECT_SCROLLBAR_CONFIG }
  ],
  bootstrap: [AppComponent]
})
export class AppModule { }

推荐答案

与 AngularFireFunctions 有同样的问题.设法通过将 AngularFireFunctionsModule 添加到我的 app.module.ts 来解决它.只需为您的 prod 构建打开 sourceMaps，这样您就可以调试实际损坏的库.事实证明，如果没有该模块，一切都可以在开发中正常工作，但是当您使用 --prod 标志优化器进行构建时，它会删除不应该删除的部分代码，并且会留下一些松散的结尾.

Had the same issue with AngularFireFunctions. Managed to solve it by adding AngularFireFunctionsModule to my app.module.ts. Just turn on sourceMaps for your prod build, so you can debug which library is actually broken. Turns out that without the module everything will work fine in development, but when you build with --prod flag optimizer removes parts of the code it shouldn't and there are loose ends left.
