Can I use multiple instances of gapi.client in the same time ?

[rubenCodeforges]

as far as i know there is only one gapi provided by google if you try to load it twice it will overide itself.
so in general you cant and i guess you should not even try it.

yes, there is only one gapi but it is possible to have multiple clients. For example: a web application that will need to use custom endpoints + public apis then there is the need to have multiple clients one for each.

@sahlouls can you give an example on how you want to use gapi ?
I just dont get what you want to achieve.
are you trying to have 2 instances of gapi.client or are you trying to include 2 gapi libraries ?

[sahlouls]

I have an application running on appengine. I use cloud endpoints so I need a gapi client (1st client). In the same time I need to interact with other services (Google+, Drive, etc ) and for these I need also other gapi clients.
Yes: How can I have multiple instances with differents configuration of gapi.client ?

Ok i got it.
So in general ng-gapi is injecting the gapi lib in to the dom and fires next() when its loaded (Observable)
this is done in https://github.com/rubenCodeforges/ng-gapi/blob/master/src/GoogleApiService.ts

As you can see the configs are just saved here , they are not used in this service.
Now if you take a look at https://github.com/rubenCodeforges/ng-gapi/blob/master/src/GoogleAuthService.ts#L28 here is where the config is used.

Let assume you have a default config which is used for the ng-gapi authService.
What you can now do is create a similar class :

@Injectable()
export class GoogleAuthService {
    private MyNewGoogleServiceOrClientOrWhatever: any = undefined;

    constructor(private googleApi: GoogleApiService) {
        this.googleApi.onLoad().subscribe(() => {
            // Reference https://developers.google.com/api-client-library/javascript/reference/referencedocs
            gapi.load('client:auth2', () => {
                let newConfigs: NgGapiClientConfig = {
                    client_id: "CLIENT_ID",
                    discoveryDocs: ["https://analyticsreporting.googleapis.com/$discovery/rest?version=v4"],
                    scope: [
                        "https://www.googleapis.com/auth/analytics.readonly",
                        "https://www.googleapis.com/auth/analytics"
                    ].join(" ")
                };
                let newService = gapi.whateverServiceYouWant.init(newConfigs);
                this.MyNewGoogleServiceOrClientOrWhatever = newService;
            });
        };
    }
}

This is just a rough example , but you should get the idea.

In general ng-gapi gives you the possibility to use gapi as Angular service and access it via observable
