CanActivate: Observable Boolean with Socket listener

Question

I'm trying to grab a property from a socket from the server like this

isVerified() {
    this.socket.emit('verify');

    return new Observable<boolean>(observer => {
        this.socket.on('isVerified', data => {
            observer.next(data)
            observer.complete()
        })
    })
}

data will either return true or false so in my route guard I have this

canActivate(): Observable<boolean> {
    this._chat.isVerified()
        .subscribe(
            res => {
                return res
            },
            err => console.log(err)
        )
}

but it tells me "A function whose declared type is neither 'void' nor 'any' must return a value." and I've been bashing my head trying to figure out to make this work and I've read plenty of other questions to no avail. Console logging res does give me true or false.

Answer 1

canActivate return type is Observable | Promise | boolean

So you should return an observable in your case:

canActivate(): Observable<boolean> {
    this._chat.isVerified();
}
