I want to implement Server-side Rendering (SSR) for a single standalone component within an Angular 17 application.
Command used to initialize SSR in the existing project:
Used this command: ng add @angular/ssr
Created a separate module named ssrdemo. Below is the structure of the module files:
Here is the Module file stracture SSR Module Files
Deleted two generated files: app.config.server.ts
and main.server.ts
Instead, created two separate files called: ssrdemo.config.server.ts
ssrdemo.component.server.ts
//ssrdemo.config.server.ts
import { mergeApplicationConfig, ApplicationConfig } from '@angular/core';
import { provideServerRendering } from '@angular/platform-server';
import { appConfig } from '../app.config';
const serverConfig: ApplicationConfig = {
providers: [
provideServerRendering()
]
};
export const config = mergeApplicationConfig(appConfig, serverConfig);
//ssrdemo.component.server.ts
import { bootstrapApplication } from '@angular/platform-browser';
import { config } from './ssrdemo.config.server';
import { ServerModule } from '@angular/platform-server';
const bootstrap = () => bootstrapApplication(SSRdemoComponentServer, config);
export default bootstrap;
import { Component } from '@angular/core';
@Component({
selector: 'app-ssrdemo',
standalone: true,
imports: [ServerModule],
templateUrl: './ssrdemo.component.html',
styleUrl: './ssrdemo.component.css'
})
export class SSRdemoComponentServer {
}
Here's the server.ts
file:
//server.ts
import { APP_BASE_HREF } from '@angular/common';
import { CommonEngine } from '@angular/ssr';
import express from 'express';
import { fileURLToPath } from 'node:url';
import { dirname, join, resolve } from 'node:path';
import bootstrap from './src/app/ssrdemo/ssrdemo.component.server';
// The Express app is exported so that it can be used by serverless Functions.
export function app(): express.Express {
const server = express();
const serverDistFolder = dirname(fileURLToPath(import.meta.url));
const browserDistFolder = resolve(serverDistFolder, '../browser');
const indexHtml = join(serverDistFolder, 'index.server.html');
const commonEngine = new CommonEngine();
server.set('view engine', 'html');
server.set('views', browserDistFolder);
// Example Express Rest API endpoints
// server.get('/api/**', (req, res) => { });
// Serve static files from /browser
server.get('*.*', express.static(browserDistFolder, {
maxAge: '1y'
}));
// All regular routes use the Angular engine
server.get('*', (req, res, next) => {
const { protocol, originalUrl, baseUrl, headers } = req;
commonEngine
.render({
bootstrap,
documentFilePath: indexHtml,
url: `${protocol}://${headers.host}${originalUrl}`,
publicPath: browserDistFolder,
providers: [{ provide: APP_BASE_HREF, useValue: baseUrl }],
})
.then((html) => res.send(html))
.catch((err) => next(err));
});
return server;
}
function run(): void {
const port = process.env['PORT'] ?? 4000;
// Start up the Node server
const server = app();
server.listen(port, () => {
console.log(`Node Express server listening on http://localhost:${port}`);
});
}
run();
After doing this it's still looking for other component and getting this error.
