## Server code
To run an Angular Universal application, you'll need a server that accepts client requests and returns rendered pages.
Create a `universal/` folder as a sibling to the `app/` folder.
Add to it the following three universal parts:
1. the [app server module](#app-server-module)
2. the [Universal engine](#universal-engine)
3. the [web server](#web-server)
{@a app-server-module}
### App server module
@ -310,64 +251,17 @@ Add to it the following three universal parts:
The app server module class (conventionally named `AppServerModule`) is an Angular module that wraps the application's root module (`AppModule`) so that Universal can mediate between your application and the server.
`AppServerModule` also tells Angular how to bootstrap your application when running as a Universal app.
Create an `app-server.module.ts` file in the `src/universal` directory with the following `AppServerModule` code:
Create an `app.server.module.ts` file in the `src/app/` directory with the following `AppServerModule` code:

Notice that it imports first the client app's `AppModule`, the Angular Universal's `ServerModule` and the `ModuleMapLoaderModule`.
The `ModuleMapLoaderModule` is a server-side module that allows lazy-loading of routes.
This is also the place to register providers that are specific to running your app under Universal.
{@a universal-engine}
### Universal template engine
The Universal `renderModuleFactory` function turns a client's requests into server-rendered HTML pages.
You'll call that function within a _template engine_ that's appropriate for your server stack.
This guide's sample is written for [Node Express](https://expressjs.com/)
so the engine takes the form of [Express template engine middleware](https://expressjs.com/en/guide/using-template-engines.html).
Create a `universal-engine.ts` file in the `src/universal` directory with the following code.
<code-example path="universal/src/universal/universal-engine.ts" title="src/universal/universal-engine.ts">
</code-example>
{@a render-module-factory}
#### Rendering the page
The call to Universal's `renderModuleFactory` is where the rendering magic happens.
<code-example path="universal/src/universal/universal-engine.ts" title="src/universal/universal-engine.ts (rendering)" region="render">
</code-example>
The first parameter is the `AppServerModule` that you wrote [earlier](#app-server-module).
It's the bridge between the Universal server-side renderer and your application.
The second parameter is an options object
* `document` is the template for the page to render (typically `index.html`).
* `url` is the application route (e.g., `/dashboard`), extracted from the client's request.
Universal should render the appropriate page for that route.
* `extraProviders` are optional Angular dependency injection providers, applicable when running on this server
{@a provide-origin}
You supply `extraProviders` when your app needs information that can only be determined by the currently running server instance.
The required information in this case is the running server's origin, provided under the `APP_BASE_HREF` token, so that the app can [calculate absolute HTTP URLs](#http-urls).
The `renderModuleFactory` function returns a _promise_ that resolves to the rendered page.
It's up to your engine to decide what to do with that page.
_This engine's_ promise callback returns the rendered page to the [web server](#web-server),
which then forwards it to the client in the HTTP response.

{@a universal-engine}
#### Universal template engine
#### Import AppServerModule factory
The important bit in this file is the `ngExpressEngine` function:
Most of this server code is re-usable across many applications.
The import of the `AppServerModule` couples it specifically to a single application.
<code-example path="universal/src/universal/server.ts" title="src/universal/server.ts" region="import-app-server-factory">
<code-example path="universal/server.ts" title="server.ts" region="ngExpressEngine">
</code-example>
Your code editor may tell you that this import is incorrect.
It refers to the source file for the `AppServerModule` factory which doesn't exist at design time.
The `ngExpressEngine` is a wrapper around the universal's `renderModuleFactory` function that turns a client's requests into server-rendered HTML pages.
You'll call that function within a _template engine_ that's appropriate for your server stack.
That file _will exist_, briefly, during compilation. But it's never physically in the file system when you're editing `server.ts` and you must tell the compiler to generate this module factory file _before_ it compiles `server.ts`.
[Learn how below](#universal-typescript-configuration).
The first parameter is the `AppServerModule` that you wrote [earlier](#app-server-module).
It's the bridge between the Universal server-side renderer and your application.
#### Add the Universal template engine
The second parameter is the `extraProviders`. It is an optional Angular dependency injection providers, applicable when running on this server.
Express supports template engines such as the [Universal template engine](#universal-engine) you wrote earlier.
You import that engine and register it with Express like this:
{@a provide-origin}
<code-example path="universal/src/universal/server.ts" title="src/universal/server.ts (Universal template engine)" region="universal-engine">
</code-example>
You supply `extraProviders` when your app needs information that can only be determined by the currently running server instance.
The required information in this case is the running server's origin, provided under the `APP_BASE_HREF` token, so that the app can [calculate absolute HTTP URLs](#http-urls).
The `ngExpressEngine` function returns a _promise_ that resolves to the rendered page.
It's up to your engine to decide what to do with that page.

## Configure for Universal
The server application requires its own web page and its own build configuration.
{@a index-universal}
### Universal web page
The universal app renders pages based on a host web page template.
Simple universal apps make do with a slightly modified copy of the original `index.html`.
<div class="alert is-helpful">
If you build a production version of the client app with the CLI's `ng build --prod` command, you do not need a separate universal `index.html`.
The CLI constructs a suitable `index.html` for you. You can skip this subsection and continue to [universal TypeScript configuration](#universal-typescript-configuration).
Read on if you're building the app without the CLI.
</div>
Create an `index-universal.html` as follows, shown next to the development `index.html` for comparison.

The differences are few.
* Load the minified versions of the `shim` and `zone` polyfills from the root (which will be `/dist`)
* You won't use SystemJS for universal nor to load the client app.
* Instead you'll load the [production version of the client app](#build-client), `client.js`, which is the result of AOT compilation, minification, and bundling.
That's it for `index-universal.html`.
Next you'll create two universal configuration files, one for TypeScript and one for Webpack.
The server application requires its own build configuration.
{@a universal-typescript-configuration}
### Universal TypeScript configuration
Create a `tsconfig.universal.json` file in the project root directory to configure TypeScript and AOT compilation of the universal app.

Certain settings are noteworthy for their difference from the `tsconfig.json` in the `src/` folder.
* The `module` property must be **es2015** because
the transpiled JavaScript will use `import` statements instead of `require()` calls.
* Point `"typeRoots"` to `"./node_modules/@types/"`
* Set the `files` property (instead of `exclude`) to compile the `app-server.module` before the `universal-engine`,
for the reason [explained above](#import-app-server-module-factory).
This config extends from the root's `tsconfig.json` file. Certain settings are noteworthy for their differences.
* The `module` property must be **commonjs** which can be require()'d into our server application.
* The `angularCompilerOptions` section guides the AOT compiler:
* `genDir` - the temporary output directory for AOT compiled code.
* `entryModule` - the root module of the client application, expressed as `path/to/file#ClassName`.
* `skipMetadataEmit` - set `true` because you don't need metadata in the bundled application.
* `entryModule` - the root module of the server application, expressed as `path/to/file#ClassName`.
### Universal Webpack configuration
Create a `webpack.config.universal.js` file in the project root directory with the following code.
Universal applications doesn't need any extra Webpack configuration, the CLI takes care of that for you,
but since the server is a typescript application, you will use Webpack to transpile it.
<code-example path="universal/webpack.config.universal.js" title="webpack.config.universal.js">
Create a `webpack.server.config.js` file in the project root directory with the following code.
<code-example path="universal/webpack.server.config.js" title="webpack.server.config.js">
</code-example>
**Webpack configuration** is a rich topic beyond the scope of this guide.
A few observations may clarify some of the choices.
* Webpack walks the dependency graph from the two entry points to find all necessary universal application files.
* The `@ngtools/webpack` loader loads and prepares the TypeScript files for compilation.
* The `AotPlugin` runs the AOT compiler (`ngc`) over the prepared TypeScript, guided by the `tsconfig.universal.json` you created [above](#universal-typescript-configuration).
* The `raw-loader` loads imported CSS and HTML files as strings.
You may need additional loaders or configuration for other file types.
* The compiled output is bundled into `dist/server.js`.
* The `CopyWebpackPlugin` copies specific static files from their source locations into the `/dist` folder.
These files include the universal app's web page template, `index-universal.html`,
and the JavaScript and CSS files mentioned in it
... with the notable exception of `client.js` [to be discussed below](#build-client).

Webpack compiles and bundles the universal app into a single output file, `dist/server.js`, per the [configuration above](#universal-configuration).
It also generates a [source map](https://webpack.js.org/configuration/devtool/), `dist/server.js.map` that correlates the bundle code to the source code.
Source maps are primarily for the browser's [dev tools](https://developers.google.com/web/tools/chrome-devtools/javascript/source-maps), but on the server they help locate compilation errors in your components.
The Angular CLI compiles and bundles the universal app into two different folders, `browser` and `server`.

Most of the console log lines report requests for static files coming from the `<link>` and `<script>` tags in the `index-universal.html`.
The `.js` files in particular are needed to run the client version of the app in the browser.

Except that it didn't!
#### Missing _client.js_ error

<code-example format="." language="bash">
Error: ENOENT: no such file or directory, stat '... dist/client.js' ...
</code-example>
The full client app doesn't launch because `client.js` doesn't exist.
And `client.js` doesn't exist because you have not yet built the client version of the app.
{@a build-client}
## Build the client app
The express server is sending the universal server-side rendered pages to the client.
But it isn't serving the interactive client app because you haven't built it yet.
A key motivation for universal is to quickly render the first page on the client so of course
you want to transition to the client app as quickly as possible too.
You should build a small, _production_ version of the client app with that AOT compiler that loads and runs fast.
#### Build the client with the CLI
If you're using the CLI to build the client app, you simply run the following command and you're done.
<code-example format="." language="bash">
ng build --prod
</code-example>
The CLI takes care of the rest, including copying all necessary files to the `/dist` folder.
By default the CLI produces two separate client app bundles, one with the vendor packages (`vendor.bundle.js`) and one with your application code (`inline.bundle.js`).
Alternatively, you can build the client using CLI _tools_ but **_without the CLI itself_**.
Read the following sub-sections if that interests you.
If not, skip ahead to the section on [throttling](#throttling).
#### Build the client by hand
You can build the application without the considerable help of the CLI.
You'll still compile with AOT.
You'll still bundle and minify with Webpack.
You'll need two configuration files, just as you did for the universal server: one for TypeScript and one for Webpack.
The client app versions are only slightly different from the corresponding server files.
Here they are, followed by notes that call out the differences:
<code-tabs>
<code-pane title="tsconfig.client.json" path="universal/tsconfig.client.json">
</code-pane>
<code-pane title="webpack.config.client.js" path="universal/webpack.config.client.js">
</code-pane>
</code-tabs>
The **_tsconfig.client.json_** inherits (via `extends`) most settings from the universal `tsconfig`. The _only_ substantive difference is in the `files` section which identifies the client app bootstrapping file, `main.ts`, from which the compiler discovers all other required files.
The **_webpack.config.client.js_** has a few differences,
all of them obvious.
* There is only one `entry.main` file, `main.ts`.
* The output filename is `client.js`.
* The `AotPlugin` references the `./tsconfig.client.json`.
* There's no need to copy asset files because the [universal Webpack config](#universal-webpack-configuration)
took care of them.
* Add the `UglifyJSPlugin` to minify the client app code.
Why minify the client code and not the server code?
You minify client code to reduce the payload transmitted to the browser. The universal server code stays on the server where minification is pointless.
#### Run Webpack for the client
Add an `npm` script to make it easy to build the client from the terminal window.
<code-example format="." language="ts">
"scripts": {
...
"build:uni-client": "webpack --config webpack.config.client.js",
...
}
</code-example>
Now run that command
<code-example format="." language="bash">
npm run build:uni-client
</code-example>
Refresh the browser.
The console log shows that the server can find `client.js`
The Universal app is quickly replaced by the full client app.
Most importantly, the event-based features now work as expected.

{@a cannot-find-module}
#### Appendix: _Cannot find module_ error
As you continue to develop the application locally,
running the `npm start` command outside of universal, the compiler may fail with the following error:
<code-example format="." language="bash">
error TS2307: Cannot find module '../../aot/src/universal/app-server.module.ngfactory'.
</code-example>
The likely cause is that you've been through these guide steps before and now have a `/universal` folder.
That folder holds server-side artifacts that are irrelevant to the client app and are confusing the compiler.
You must exclude the _server-side_ `/universal` folder files from _client app_ compilation.
Open `tsconfig.json`, find the `"exclude"` node and add `"universal/*"` to the array.
The result might look something like this:
```
"exclude": [
"node_modules/*",
"universal/*"
]
```
Compile and run again with `npm start`.
