Introduced the `createRequestHandler` and `createNodeRequestHandler` utilities to expose middleware functions from the `server.ts` entry point for use with Vite.
This provides flexibility in integrating different server frameworks, including Express, Hono, and Fastify, with Angular SSR.
Examples:
**Express**
```ts
export default createNodeRequestHandler(app);
```
**Nest.js**
```ts
const app = await NestFactory.create(AppModule);
export default createNodeRequestHandler(app);
```
**Hono**
```ts
const app = new Hono();
export default createRequestHandler(app.fetch);
```
**Fastify**
```ts
export default createNodeRequestHandler(async (req, res) => {
await app.ready();
app.server.emit('request', req, res);
});
```
Adds a new function `isMainModule` that checks if the current module is the main entry point of the application.
This is useful to ensure that server listener handlers are only registered when the module is executed directly and not when it's imported as a dependency such as the dev-server. This prevents potential issues with multiple listeners being registered unintentionally.
Expose a variant of `AngularAppEngine` tailored for Node.js. These additions streamline the process by minimizing boilerplate code and eliminate the need for users to call `createWebRequestFromNodeRequest` before invoking the render method.
These additions enhance server-side rendering capabilities by providing more flexibility in handling web requests and responses within Node.js environments.
Refactored the `CommonEngine` API import path to remove Node.js dependencies from the `@angular/ssr` main entry-point.
BREAKING CHANGE:
The `CommonEngine` API now needs to be imported from `@angular/ssr/node`.
**Before**
```ts
import { CommonEngine } from '@angular/ssr';
```
**After**
```ts
import { CommonEngine } from '@angular/ssr/node';
```
