How to check the condition if the json data (coming from backend) has a key value in angular

Issue

In my angular application I Have fetched the data from the server and it is in json format like

jsondata = { 
    Id: 16531914, 
    EmailId: "abc@gmail.com" 
}

And my requirement is if the jsondata(coming from server ) has the Id then I have to navigate to the dashboard page else I have to go to the login page

Solution

you can simply use an if chek

if(jsondata.Id) return this.router.navigate([...other routes, jsondata.Id]) 
this.router.navigate(['/login'])
