为什么角通用服务器端渲染得到一个错误，在火力地堡托管部署后？

问题描述 投票：1回答：2

我目前对角工作使用其第三方库，如角CLI /角通用以下链接https://github.com/angular/angular-cli/wiki/stories-universal-rendering /和火力托管/和实时数据库。它在我的本地机器上工作的伟大监听，本地主机：4000。我把它渲染服务器端渲染顺利，我看见我需要的搜索引擎友好的我也用延迟加载，它改进了Web应用程序性能的加载速度非常快的HTML。现在，我的问题是，当我部署我与通用服务器端渲染也有延迟加载角应用。我得到这个错误的说法，错误：而且如果我只是不部署延迟加载我得到这个3个错误无法处理请求，

1. Uncaught SyntaxError: Unexpected token < inline.318b50c57b4eba3d437b.bundle.js:1 

2. Uncaught SyntaxError: Unexpected token < polyfills.bf95165a1d5098766b92.bundle.js:1

3. Uncaught SyntaxError: Unexpected token < main.4871dfc6be55ccbf4c0b.bundle.js:1

这里的文件夹结构：

  • DIST =>这是角应用程序的生成文件夹 浏览器 服务器 server.js
  • DONC
  • 功能=>这是生成文件夹，我用它来上传到火力托管 浏览器 node_modules 服务器 .eslintrc.json index.js 包lock.json 的package.json server.js
  • node_modules
  • 服务器=>我使用transpile index.ts到index.js index.ts tsconfig.functions.json

当你的重定向规则发送索引页，而不是的JavaScript，请检查同一问题here，通常是错误。

更新您的package.json scripts像如下：

        "scripts": {
          "ng": "ng",
          "start": "ng serve",
          "build": "ng build --prod",
          "build.server": "ng build -aot -app ssr",
          "test": "ng test",
          "lint": "ng lint",
          "e2e": "ng e2e"
        },

然后.angular-cli.json "main": "main.ts"到"main": "main.server.ts"。

构建应用程序的浏览器和服务器版本

npm run build
npm run build.server

请检查教程到这里Deploy Angular Universal w/ Firebase和demo。

希望这将帮助你！

我的问题是在supervisor.conf文件。在节点环境的路线是拼写错误。正确的路线是：

环境= NODE_ENV =生产

这将导致我所有的“意外的标记<”问题

我有一个类似的问题给您，并能够从DIST文件夹移动我的server.js文件到上面的目录来解决它。

所以，我的文件夹/文件结构如下所示：

  • Webroot公司 - 根文件夹 server.js DIST（文件夹） 浏览器（子） 服务器（子）
