Angular 对现有项目通用

Question

所以我按照这个 article 在预先存在的 angular 5 项目上实施 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

所以显然 Whosebug 抱怨我的 post 主要是代码，所以我想我必须多写一点才能允许 post 这个问题，请耐心等待。遇到这种情况，有什么出路？

Answer 1

我在你的依赖项中没有看到 ts-loader

npm install --save ts-loader@3.5.0

理想情况下，您应该按照官方文档设置 Angular Universal。有效：

https://angular.io/guide/universal

一个工作示例here。

Answer 2

截至今天，运行 Server-Side 使用 Angular Universal 到 Angular 的渲染就像这两个步骤一样简单：

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