【问题描述】:
在我的 Angular 组件中,particles.js 运行良好,在客户端使用 ng serve 渲染时效果很好。但是,当将它与 Angular Universal 用于服务器端渲染 (SSR) 结合使用时,我收到错误 ERROR ReferenceError: particlesJS is not defined。我曾尝试使用 webpack 将其列入白名单,但没有成功,webpack 的代码如下:
config.externals = nodeExternals({
// The whitelisted ones will be included in the bundle.
whitelist: [/^ng-circle-progress/, /^ng2-tel-input/, /^particles.js/]
});
其他 2 个包的错误已经消失,但这个不希望消失。
我的后端使用NestJS,尝试applyDomino,但也没有用,代码如下:
import { AngularUniversalModule, applyDomino } from '@nestjs/ng-universal';
import { join } from 'path';
import { Module } from '@nestjs/common';
// Get working directory of client bundle.
const BROWSER_DIR = join(
process.cwd(),
'functions',
'dist',
'apps',
'ditectrev-browser'
); // Use when testing locally without Firebase Cloud Functions solely on NestJS.
// const BROWSER_DIR = join(process.cwd(), 'dist/apps/ditectrev-browser'); // Use when deploying to & testing with Firebase Cloud Functions.
applyDomino(global, join(BROWSER_DIR, 'index.html'));
@Module({
imports: [
AngularUniversalModule.forRoot({
bundle: require('./../functions/dist/apps/ditectrev-server/main'), // Bundle is created dynamically during build process.
liveReload: true,
viewsPath: BROWSER_DIR
})
]
})
export class AppModule {}
有趣的是,即使我收到错误消息,页面也会在服务器端正确呈现!它确实不会中断。单独使用 Cloud Functions for Firebase(本地和部署)进行渲染时也会出现同样的错误。
注意:这个话题没有帮助找到我的问题particles.js and window is not defined的答案
