Angular Universal does not render index.html
I am in need of some help.
I want to render my Angular application with Angular Universal. I generated my server files with ng generate universal my-app (@angular/cli@1.6.0) which generated all the necessary server files (main.server.ts, tsconfig.server.ts,...). I made a server.ts file in my root directory (the code is the same as in the cli documentation) and a webpack.config.js file (also the same). The build processs finishes without an error, but when I try to open the page in the browser I get Error and nothing else (page). When I checked the network tab I saw network error. But if I try to open localhost:4000/index.html the index file gets served/rendered.
Note the console.log("does it get here"); in server.ts, It gets logged out when I check the console. But index is not rendered.
server.ts
// These are important and needed before anything else
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 { join } from 'path';
import { readFileSync } from 'fs';
// Faster server renders w/ Prod mode (dev mode never needed)
enableProdMode();
// Express server
const app = express();
const PORT = process.env.PORT || 4000;
const DIST_FOLDER = join(process.cwd(), 'dist');
// Our index.html we'll use as our template
const template = readFileSync(join(DIST_FOLDER, 'browser', 'index.html')).toString();
// * NOTE :: leave this as require() since this file is built Dynamically from webpack
const { AppServerModuleNgFactory, LAZY_MODULE_MAP } = require('./dist/server/main.bundle');
const { provideModuleMap } = require('@nguniversal/module-map-ngfactory-loader');
app.engine('html', (_, options, callback) => {
renderModuleFactory(AppServerModuleNgFactory, {
// Our index.html
document: template,
url: options.req.url,
// DI so that we can get lazy-loading to work differently (since we need it to just instantly render it)
extraProviders: [
provideModuleMap(LAZY_MODULE_MAP)
]
}).then(html => {
callback(null, html);
});
});
app.set('view engine', 'html');
app.set('views', join(DIST_FOLDER, 'browser'));
// Server static files from /browser
app.get('*.*', express.static(join(DIST_FOLDER, 'browser')));
// All regular routes use the Universal engine
app.get('*', (req, res) => {
console.log("does it get here");
res.render(join(DIST_FOLDER, 'browser', 'index.html'), { req });
});
// Start up the Node server
app.listen(PORT, () => {
console.log(`Node server listening on http://localhost:${PORT}`);
});
I also downloaded the angular-universal-started, but it works there, so what am I doing wrong? Did anyone encounter the same error? I would really appreciate some help :D
UPDATE: I figured out that it was because of ngx-translate package. I think it is because the server side rendering doesn't support http requests and the translate file should be fetched from the file system and not with a http request (i think).
