If you set writable: false, then the value in your "constant" cannot be modified. Hi Readers , I hope you all are doing good and read my all the previous tutorials . Angular Development has been around for quite a while, in contrast to Blazor. @Anuj yes, you can use service for it. ; Back to Top In comparison between Blazor vs Angular performance, Blazor is constantly being changed Back to Top. While a small application might have only one NgModule, most applications have many more feature modules. onClick(row: any) { this.shareService.setData(row); this.router.navigate(['/page2'])} and in your page2 you can get this data ngOnInit() { const data = this.shareService.getData(); } Hope it helps Angular service Factory; 1.
