Status of the response - Angular 5

Question

I have created a simple GET on my base.service to get a response if the URL is valid or not.

/** Check connection */
checkConnection(url: string) {
    return this.http.get(url);
}

and I would like to call it with a URL from one of my components and read the status of the response:

checkConnection(protocol, host, port) {
    const url = protocol.toLowerCase().concat("://").concat(host).concat(":").concat(port);
    this.baseService.checkConnection(url)
        .subscribe(
            response => {
                let status = response.status;
            },
            (err) => console.log(err)
        );
}

but I am getting an error on it

Porperty status does not exist on type 'Ojbect'

so it is not able to compile

Your issue regards typescript itself, as response has no clear type in your code.

Assuming you're using HttpClient, according to docs, the get observable is not clearly typed (https://angular.io/api/common/http/HttpClient#get).

A simple solution would be to use any:

.subscribe(
        (response: any) => {
            let status = response.status;
        },
