Lazy Loaded Modules with AOT - TypeError: '' is not a function when served from NGINX
Lazy Loaded Modules with AOT - TypeError: '' is not a function when served from NGINX
这里是我自己复制的 dist 文件：
细分：
- 我的带有 AOT 和延迟加载模块的 dist 构建在与 npm 包 webpack-dev-server 或 live-server 一起使用时工作正常
- 只有当我将 dist 复制到 NGINX html 目录并且 NGINX 提供我在 Firefox 中看到 Javascript 错误和 Chrome
的文件时
- 我尝试过很多不同的 webpack 配置。
- 我没有在任何 Typescript 文件中导入我的延迟加载模块
- 关闭 AOT 编译后，我的应用程序和惰性模块在 NGINX 中运行良好
- TypeError: '' is not a function 错误来自与 NGINX 一起提供的延迟加载模块
我正在使用官方 Angular 包 @ngtools/webpack 将 AOT 编译添加到我的 Angular 5 应用程序。 This article explains how to use @ngtools/webpack to add AOT to a Webpack build project. Very simple, though the article does not mention the needed step to add the Lazy Load module file paths 到 tsconfig-aot.json。 AOT 没有那一步就失败了。
本地主机都很好用：
npm run serve
我的 npm run serve 命令是内存编译，使用 npm 包 webpack-dev-server.
从内存中为本地主机提供资源
当我部署到我的开发服务器时，编译文件存储在磁盘上，我的开发服务器使用 NGINX.
提供资源
我有延迟加载的模块，在加载时会在 Firefox 中抛出类似这样的奇怪错误：
TypeError: i0.\u0275crt is not a function
Chrome中的这个：
ERROR TypeError: i0.ɵcrt is not a function
关于 Chrome 中错误的更多细节，这里是源映射代码行抛出错误：
我看到var i0的创建是这一行：
var i0 = __webpack_require__(/*! @angular/core */ "./node_modules/@angular/core/esm5/core.js");
在我的开发服务器上，node_modules 与我的 dist 文件夹的父级一样：
我的开发服务器上的文件：
这是从本地主机提供的资源文件的比较：

好的，这是我的配置和 npm 包版本：

在 Angular 8 中，我们需要将旧的延迟加载方式更改为动态导入，并且需要更改模块：'esnext' 和目标：tsconfig.json 中的 'es2015'文件.

这是因为当你使用AOT时，代码被一些有趣的UTF-8符号丑化了； ɵ 在 i0.ɵcrt 你的情况
你需要告诉nginx使用UTF-8字符集
server {
listen 80 default_server;
listen [::]:80 default_server;
server_name _;
charset UTF-8; #<==== Add this
将 /etc/nginx 文件夹中的当前 nginx.conf 文件替换为以下内容，

延迟加载的路由将包含哈希值，location ~* "^/[a-z0-9]{40}.(css|js)$" {这将解决问题
在 Angular 8 中，我们需要将旧的延迟加载方式更改为动态导入，并且需要更改模块：'esnext' 和目标：tsconfig.json 中的 'es2015'文件.
