Angular2/Typescript - setting default query string parameters

In my current project, I have a component that checks for specific parameters in a query string and performs certain actions based on their existence. However, every time I try to transpile the code, I encounter errors like:

Error TS2339: Property 'oauth_token' does not exist on type '{ [key: string]: any; }'

The constructor and ngOnInit method of my component are as follows:

constructor ( 
    private router: Router
) {}

ngOnInit() {

    if ( this.router.routerState.snapshot.queryParams.hasOwnProperty('oauth_token') ) {
... do stuff here ...

    }
}

I would appreciate it if someone could offer advice on how to handle default query string parameters efficiently.

Answer №1

To retrieve the properties, you can simply utilize the [] operator:

const token = this.router.routerState.snapshot.queryParams['access_token'];
if (token) {
  // Perform desired actions
}
