angular-universal

问题 Goal Question looks long winded - it's not! I'm using Angular Universal to implement SSR, following this tutorial. Universal/express-engine is installed, main.js is generated in the dist/projectname/server folder, and I've created a prerender.js folder in the project root. Problem When I try npm run prerender it starts work prerendering until eventually hitting the following error: Prerendering 5 route(s) to C:\Users\odubh\Documents\Personal_Web_Projects\Hibernio.com\Hibernio0.3\hibernio\dist

问题 I am using an Angular 9 .net core spa app. On pages with api call the app becomes stuck (pending on the Network tab in Chrome) and comes back with (failed) net:ERR_EMPTY_RESPONSE The home page works fine and uses an api on the ng-init event and other pages without an api call work fine and I can jump between these pages back and forth without an issue. It just other pages that that depend on an api call give the problem. The web.config is empty as I just build within VS 2019 and publish.

问题 I'm making a SSR with Angular 7 and Angular Universal, but when I use Fusioncharts from third parties I've got this errors when i run this script npm run build:ssr && npm run serve:ssr ReferenceError: window is not defined at Object.undefined.module.exports.module.exports (C:\Users\ridho.fauzan\Documents\angular-app\bizhare-frontend\desktop\dist\server.js:161938:807) I've tried to use domino on the server.ts files but it still not working this is my server.ts file import 'zone.js/dist/zone

问题 I've seen many articles about caching data for client in angular universal apps, so it doesn't duplicate the requests on client that has been already resolved on server. I just don't get how the data is transferred from server to the client. Do I inject the JSON to pre-rendered HTML or am I missing something else ? 回答1: As of angular 5, there is a module inside angular core called TransferStateModule that does this for you. https://angular.io/api/platform-browser/TransferState You simply add
