Application always serves '/' to express app - node.js

Question

Have an angular 7 application and have implemented angular universal using node and express, and then deployed to firebase.
Having an issue when trying to load pages other than the root (/), which causes the server to return the html of the root (/) rather than the page the user requests.
Not sure from where the issue is originating (Angular, Angular Universal or Firebase).
This is my index.ts:
import * as functions from 'firebase-functions';
import 'zone.js/dist/zone-node';
import 'reflect-metadata';
import {renderModuleFactory} from '#angular/platform-server';
import {enableProdMode} from '#angular/core';
import * as express from 'express';
import {readFileSync} from 'fs';
enableProdMode();
const app = express();
const indexHtml = readFileSync(__dirname + '/index-server.html', 'utf-8').toString();
const {AppServerModuleNgFactory, LAZY_MODULE_MAP} = require('./main');
import {provideModuleMap} from '#nguniversal/module-map-ngfactory-loader';
app.engine('html', (_, options, callback) => {
// Always '/' (root path)
console.log('OPTIONS.REQ.URL', options.req.url);
renderModuleFactory(AppServerModuleNgFactory, {
// My index-server.html
document: indexHtml,
url: options.req.url,
extraProviders: [
provideModuleMap(LAZY_MODULE_MAP)
]
}).then(html => {
callback(null, html);
});
});
app.set('view engine', 'html');
app.set('views', __dirname);
app.get('*.*', express.static(__dirname + '/dist', {
maxAge: '1y'
}));
app.get('*', (req, res) => {
res.render(__dirname + '/index-server.html', {req});
});
exports.ssrApp = functions.https.onRequest(app);
This is my app-routing.module.ts:
import {RouterModule, Routes} from '#angular/router';
import {NgModule} from '#angular/core';
import {HomePageComponent} from './home-page/home-page.component';
import {ToursComponent} from './tours/tours.component';
import {MaltaComponent} from './malta/malta.component';
import {AboutComponent} from './about/about.component';
import {ContactComponent} from './contact/contact.component';
import {TourComponent} from './tours/tour/tour.component';
import {ErrorComponent} from './error/error.component';
import {BlogComponent} from './blog/blog.component';
import {BlogPageComponent} from './blog/blog-page/blog-page.component';
import {PageResolver} from './services/pages/page-resolver.service';
const AppRoutes: Routes = [
{
path: 'home',
component: HomePageComponent,
data: {
state: 'home',
pageId: 'home'
},
resolve: {
page: PageResolver
}
},
{
path: 'tours',
component: ToursComponent,
data: {
state: 'tours',
pageId: 'tours'
},
resolve: {
page: PageResolver
}
},
{
path: 'tours/:id',
component: TourComponent,
data: {
state: 'tour'
}
},
{
path: 'blog',
component: BlogComponent,
data: {
state: 'blogs',
pageId: 'blog'
},
resolve: {
page: PageResolver
}
},
{
path: 'blog/:id',
component: BlogPageComponent,
data: {
state: 'blog'
}
},
{
path: 'malta',
component: MaltaComponent,
data: {
state: 'malta',
pageId: 'malta'
},
resolve: {
page: PageResolver
}
},
{
path: 'about',
component: AboutComponent,
data: {
state: 'about',
pageId: 'about'
},
resolve: {
page: PageResolver
}
},
{
path: 'contact',
component: ContactComponent,
data: {
state: 'contact',
pageId: 'contact'
},
resolve: {
page: PageResolver
}
},
{
path: 'something-went-wrong',
component: ErrorComponent,
data: {
state: 'error',
pageId: 'error'
}
},
{
path: '',
redirectTo: '/home',
pathMatch: 'full'
},
{
path: '**',
redirectTo: '/something-went-wrong'
}
];
#NgModule({
imports: [
RouterModule.forRoot(AppRoutes, {
useHash: true,
scrollPositionRestoration: 'enabled',
initialNavigation: 'enabled'
})
],
exports: [RouterModule]
})
export class AppRoutingModule {
}
This is my firebase.json:
{
"hosting": {
"public": "dist",
"ignore": [
"firebase.json",
"**/.*",
"**/node_modules/**"
],
"rewrites": [
{
"source": "**",
"function": "ssrApp"
}
]
},
"functions": {
"predeploy": "npm --prefix \"$RESOURCE_DIR\" run build"
}
}
Would appreciate any help with this issue!

Answer 1

The issue is solved after removing useHash: true from the app-routing.module.ts.
Thanks to yeya for helping get to the solution.

Answer 2

Your issue is related to Browser URL styles
Based on this answer: Try change the rewrites from "function": "ssrApp" to "destination": "/index-server.html"
The requestindex-server.html will trigger the function.
