Angular2 APP_INITIALIZER not consistent

Question

I am using APP_INITIALIZER like it is recommended in this answer, with my service returning a promise, but it doesn\'t always wait for it to resolve and I can see my compone

Answer 1

Try the following code:

getUser(): Promise {
    console.log('get user called');
    var promise = this.http.get('/auth/getuser', {headers: getHeaders()})
        .map(extractData)
        .toPromise();
    promise.then(user => {
        this.user = user;
        console.log(this.user);
    });
    return promise;
}

I was facing the same problem, and using a promise instead of a observable did the trick for me.
