现有项目上的 Angular 通用

Question

所以我按照这篇文章在预先存在的 angular 5 项目上实现 SSR 并在我运行命令时遇到了这些问题

./node_modules/.bin/ts-node ./server.ts

这是我控制台的输出

ce0@ce0 ~/Documents/Angular/exampleSSR $ ./node_modules/.bin/ts-node ./server.ts

/home/ce0/Documents/Angular/exampleSSR/node_modules/ts-node/src/index.ts:300

显然，stackoverflow 抱怨我的帖子主要是代码，所以我想我必须多写一点才能让我发布问题，请耐心等待。 在这种情况下有什么出路？

Answer 1

截至今天，使用Angular Universal到Angular运行服务器端渲染就像这两个步骤一样简单：

1. ng add @nguniversal/express-engine --clientProject {{ name of your project }}
2. npm run build:ssr && npm run serve:ssr

关于每个自动创建/修改的文件的作用的解释已在此处完美解释https://www.digitalocean.com/community/tutorials/angular-angular-universal

Answer 2

我在您的依赖项中没有看到ts-loader

npm install --save ts-loader@3.5.0

理想情况下，您应该遵循官方文档来设置 Angular Universal。 有用：

https://angular.io/guide/universal

这里有一个工作示例。
