SSR Angular 8 应用程序具有未定义的延迟加载模块
SSR Angular 8 application have lazy-load modules as undefined
我正在尝试使用 SSR 将我的 Angular 8 应用程序设置为 运行，但是当我使用 运行 我的应用程序 ng serve。
它在 Angular 7 之前工作正常，但去 Angular 8 破坏了一切。
这是我在 运行 时间（在节点控制台中）
遇到的错误

我尝试更改一些 tsconfig 和 angular.json 配置，但我总是遇到同样的错误。
Ivy 未启用，因为它还会在构建时触发一些错误；我认为它已链接但我不确定所以现在我正在尝试在没有常春藤的情况下让它工作

我正在使用 npm run build:ssr 构建我的应用程序并使用 npm run serve:ssr
提供它
我需要我的应用程序渲染所有模块和带有 SSR 的标记以用于 SEO 目的，并且希望对问题所在提供一些帮助。
问题是在设置 Universal 的旧方法中有两个 Angular 的副本，它混淆了延迟加载系统。
您可以通过更新以下内容手动修复此问题：
package.json
add --bundleDependencies all at the end of the value of
build:client-and-server-bundles
server.ts
remove the following lines
import {enableProdMode} from '@angular/core';
import {ngExpressEngine} from '@nguniversal/express-engine';
import {provideModuleMap} from '@nguniversal/module-map-ngfactory-loader';
enableProdMode();
const {AppServerModuleNgFactory, LAZY_MODULE_MAP} = require('./dist/server/main');
then add
const {AppServerModuleNgFactory, LAZY_MODULE_MAP, ngExpressEngine, provideModuleMap} = require('./dist/server/main');
main.server.ts
add
export {ngExpressEngine} from '@nguniversal/express-engine';
export {provideModuleMap} from '@nguniversal/module-map-ngfactory-loader';
webpack.server.config.js
add
externals: {
'./dist/server/main': 'require("./server/main")'
}
运行 进入同一期，这一期也是：https://github.com/angular/universal/issues/1195. What worked for me was to apply the fix (https://github.com/angular/universal/blob/master/docs/v8-upgrade-guide.md)，但不包括 --bundleDependencies all 标志。
这是一个使用 gCloud 进行 SSR 的基本工作示例：
https://github.com/jrodl3r/ng-fire-universal
长话短说 - 我刚刚从 server.ts 中删除了 enableProdMode();，它开始工作了。
angular 7 在这里，但是 angular 8 需要在 server.ts 文件中更改代码，所以
- 我制作了server.bak.ts作为备份文件，
- 使用 SSR 和
设置新的空白项目
- 从中获取代码到 server.ts 文件。
我正在尝试使用 SSR 将我的 Angular 8 应用程序设置为 运行，但是当我使用 运行 我的应用程序 ng serve。
它在 Angular 7 之前工作正常，但去 Angular 8 破坏了一切。
这是我在 运行 时间（在节点控制台中）

我正在使用 npm run build:ssr 构建我的应用程序并使用 npm run serve:ssr
我需要我的应用程序渲染所有模块和带有 SSR 的标记以用于 SEO 目的，并且希望对问题所在提供一些帮助。
问题是在设置 Universal 的旧方法中有两个 Angular 的副本，它混淆了延迟加载系统。
您可以通过更新以下内容手动修复此问题：
package.json
add
--bundleDependencies allat the end of the value ofbuild:client-and-server-bundles
server.ts
remove the following lines
import {enableProdMode} from '@angular/core'; import {ngExpressEngine} from '@nguniversal/express-engine'; import {provideModuleMap} from '@nguniversal/module-map-ngfactory-loader'; enableProdMode(); const {AppServerModuleNgFactory, LAZY_MODULE_MAP} = require('./dist/server/main');then add
const {AppServerModuleNgFactory, LAZY_MODULE_MAP, ngExpressEngine, provideModuleMap} = require('./dist/server/main');
main.server.ts
add
export {ngExpressEngine} from '@nguniversal/express-engine'; export {provideModuleMap} from '@nguniversal/module-map-ngfactory-loader';
webpack.server.config.js
add
externals: { './dist/server/main': 'require("./server/main")' }
运行 进入同一期，这一期也是：https://github.com/angular/universal/issues/1195. What worked for me was to apply the fix (https://github.com/angular/universal/blob/master/docs/v8-upgrade-guide.md)，但不包括 --bundleDependencies all 标志。
这是一个使用 gCloud 进行 SSR 的基本工作示例： https://github.com/jrodl3r/ng-fire-universal
长话短说 - 我刚刚从 server.ts 中删除了 enableProdMode();，它开始工作了。
angular 7 在这里，但是 angular 8 需要在 server.ts 文件中更改代码，所以
- 我制作了server.bak.ts作为备份文件，
- 使用 SSR 和 设置新的空白项目
- 从中获取代码到 server.ts 文件。
