  • Search engines can parse the page since it is rendered on the server.Socia media platforms like Facebook and Twitter can show a preview of the site when shared.Once a webpage is rendered on the server, you can cache it and serve it much faster.To implement server side rendering in your…
  • The browser module calls method which tells Angular we are using server side rendering and the view has to be swapped once the full framework is loaded.Entry Point: You also have two entry points for you application: src/main.
  • Create a webpack.server.config.js file in the root directory of your application and add the following code:To your package.json file, add the following commands to your scripts array:”build:ssr”: “npm run npm run webpack:server”,”serve:ssr”: “node “ng build –prod ng build –prod –app 1 “webpack –config webpack.server.config.js –progress –colors”First run npm run build:ssr…
  • When an API call is made, you will store the data returned in the state using the key you created with makeStateKey.In the file you are consuming your API, import the TransferState and makeStateKey modules.import { TransferState, makeStateKey } from the TransferState service into your constructor function:constructor( private state: TransferState,…
  • When you get your data back from the http call, store it in the state using this.state.set.functionName() { let variable_name = this.state.get(KEY_NAME, null as any); if (variable_name) { return Observable.of(variable_name); } return this.http.get(‘url’) … this.state.set(KEY_NAME, variable_name as any); return variable_name; }Now your client will not make an HTTP call when…

There are a few reasons you may want to use Server-Side Rendering with your Angular application.SSR helps with Search Engine Optimization. Search engines can parse the page since it is rendered on the server.Socia media platforms like Facebook and Twitter can show a preview of the site when shared.Once a webpage is rendered on the server, you can cache it and serve it much faster.To implement server side rendering in your Angular application, you can use the Angular Universal package.Angular UniversalCreate new Angular project:ng new project-nameInside that project, download the following packages and add Angular Universal:cd project-namenpm install –save @angular/platform-server ts-loader expressng generate universal project-nameThis creates and updates the following files:create src/main.server.ts create src/tsconfig.server.json update package.json update .angular-cli.json update src/main.ts update src/app/app.module.ts update .gitignore Modules: You now have two separate root modules: app.server.module.tsand app.module.ts. The server module imports ServerModule from the @angular/platform-server package. The browser module calls method which tells Angular we are using server side rendering and the view has to be swapped once the full framework is loaded.Entry Point: You also have two entry points for you application: src/main.ts and src/main.server.ts. The latter is the entry point for the server, and simply exports our server module.Config files: To tell the Angular compiler that we have two entry modules, the tsconfig.server.json file is created. The tsconfig.app.json compiles the browser application.Angular CLI: In the angular-cli.json file, a second profile is added for the server bundle.Bootstrapping: Your main.ts file is updated with the following () = { .catch(err = console.log(err));});This is…
