I was just trying to update my angular application from version 15 to 16. Everything works with angular. Even it makes build for angular universal with no error. But when I try to serve with npm run serve:ssr
it throws error
TypeError: Right-hand side of 'instanceof' is not an object
Initially I thought it could be some error in my code but I remove entire code and keep only app component with a simple heading. It still throws same error.
server.ts
import { enableProdMode } from "@angular/core";
(global as any).WebSocket = require('ws');
(global as any).XMLHttpRequest = require('xhr2');
import 'zone.js/dist/zone-node';
const domino = require('domino');
const fs = require('fs');
const path = require('path');
import { ngExpressEngine } from '@nguniversal/express-engine';
import * as express from 'express';
import { join } from 'path';
import { existsSync } from 'fs';
const dotenv = require('dotenv');
dotenv.config();
const distFolder = join(process.cwd(), 'dist/project-name/browser');
const template = fs.readFileSync(path.join(distFolder, 'index.html')).toString();
const win = domino.createWindow(template.toString());
global['window'] = win;
global['document'] = win.document;
global['DOMTokenList'] = win.DOMTokenList;
global['Node'] = win.Node;
global['Text'] = win.Text;
global['HTMLElement'] = win.HTMLElement;
global['navigator'] = win.navigator;
global['getComputedStyle'] = win.getComputedStyle;
// (global as any).self = {fetch: require('node-fetch')};
// Faster server renders w/ Prod mode (dev mode never needed)
enableProdMode();
import { AppServerModule } from './src/main.server';
import { APP_BASE_HREF } from '@angular/common';
// The Express app is exported so that it can be used by serverless Functions.
export function app(): express.Express {
const server = express();
const distFolder = join(process.cwd(), 'dist/project-name/browser');
const indexHtml = existsSync(join(distFolder, 'index.original.html')) ? 'index.original.html' : 'index';
// Our Universal express-engine (found @ https://github.com/angular/universal/tree/main/modules/express-engine)
server.engine('html', ngExpressEngine({
bootstrap: AppServerModule
}));
server.set('view engine', 'html');
server.set('views', distFolder);
// Example Express Rest API endpoints
// server.get('/api/**', (req, res) => { });
// Serve static files from /browser
server.get('*.*', express.static(distFolder, {
maxAge: '1y'
}));
// All regular routes use the Universal engine
server.get('*', (req, res) => {
res.render(indexHtml, { req, providers: [{ provide: APP_BASE_HREF, useValue: req.baseUrl }] });
});
return server;
}
function run(): void {
const port = process.env.PORT || 8000;
// Start up the Node server
const server = app();
server.get('/env', (req, res) => {
res.json(process.env);
})
server.listen(port, () => {
console.log(`Node Express server listening on https://localhost:${port}`);
});
}
// Webpack will replace 'require' with '__webpack_require__'
// '__non_webpack_require__' is a proxy to Node 'require'
// The below code is to ensure that the server is run only when not requiring the bundle.
declare const __non_webpack_require__: NodeRequire;
const mainModule = __non_webpack_require__.main;
const moduleFilename = mainModule && mainModule.filename || '';
if (moduleFilename === __filename || moduleFilename.includes('iisnode')) {
run();
}
export * from './src/main.server';
Is there anything I am missing?
I got work around with the help of temperoary forked extension for domino
npm install domino-ext
.domino
with domino-ext
in server.ts
file.const domino = require('domino');
Replace with
const domino = require('domino-ext');
Now make build and serve, it will worked fine afterwards.
