Description

Angular Universal module for Nest.

Installation

Using the Angular CLI:

$ ng add @nestjs/ng-universal

Or manually:

$ npm i @nestjs/ng-universal

Example

See full example here.

Usage

If you have installed the module manually, you need to import AngularUniversalModule in your Nest application.

import { Module } from '@nestjs/common';
import { join } from 'path';
import { AngularUniversalModule } from '@nestjs/ng-universal';

@Module({
  imports: [
    AngularUniversalModule.forRoot({
      bootstrap: AppServerModule,
      viewsPath: join(process.cwd(), 'dist/{APP_NAME}/browser')
    }),
  ],
})
export class ApplicationModule {}

API Spec

The forRoot() method takes an options object with a few useful properties.

| Property | Type | Description | | ------------- | ------------- | ----- | | viewsPath | string | The directory where the module should look for client bundle (Angular app) | | bootstrap | Function | Angular server module reference (AppServerModule). | | templatePath | string? | Path to index file (default: {viewsPaths}/index.html) | | rootStaticPath | string? | Static files root directory (default: *.*) | | renderPath | string? | Path to render Angular app (default: *) | | extraProviders | StaticProvider[]? | The platform level providers for the current render request |

Request and Response Providers

This tool uses @nguniversal/express-engine and will properly provide access to the Express Request and Response objects in you Angular components.

This is useful for things like setting the response code to 404 when your Angular router can't find a page (i.e. path: '**' in routing):

import { Response } from 'express';
import { Component, Inject, Optional, PLATFORM_ID } from '@angular/core';
import { isPlatformServer } from '@angular/common';
import { RESPONSE } from '@nguniversal/express-engine/tokens';

@Component({
  selector: 'my-not-found',
  templateUrl: './not-found.component.html',
  styleUrls: ['./not-found.component.scss'],
})
export class NotFoundComponent {
  constructor(
    @Inject(PLATFORM_ID)
    private readonly platformId: any,
    @Optional()
    @Inject(RESPONSE)
    res: Response,
  ) {
    // `res` is the express response, only available on the server
    if (isPlatformServer(this.platformId)) {
      res.status(404);
    }
  }
}
