Expression expected when trying to access query params in Angular 2

I tried to access query params using below code.

let name : string = this.route.snapshot?.queryParams.name
        console.log(name);

And I got the below error:

error TS1109: Expression expected

error TS1005: ':' expected

does not exist on type 'Params'.

How to resolve this issue.

I think that your problem lies in the way you treat queryParams. It returns observable so you can change your code like that:

let name: string = '';
this.route.queryParams.subscribe(res => {
                          name = res.ResponseNameProperty;
                          console.log(name);                           
                       });

The res.ResponseNameProperty is way how you get the name property from revived object so you can first check how it looks using i.e. console.log(res) and than use appropriate reference. I hope it fits your question and here you can found additional information about observables: thoughtram , official page, SO post
