Angular 7 waiting Service reply to continue

Angular 7 waiting Service reply to continue

Good Afternoon, folks, I own two methods, how do I wait for a method that is calling an external service to respond to continue executing the method that called that method? Example:

salvarUsuario(){
this.usuario = formUsuario.value();
this.pegarEndereco(this.usuario.cep);
this.usuarioService.salvar().subscribe();
}

pegarEndereco(cep: string){
this.cepService.buscarPorCep(cep).subscribe((response: any) => {
this.usuario.endereco = response;
});
}

In this case, I only want to continue the execution after the pick () address responds.

Note: I did not want to make the call inside the cepService subscribe.search bycep (cep)

You can make a " subscribe "in the" getdirectory " function within the user save.

salvarUsuario(){
  this.usuario = formUsuario.value();
  this.pegarEndereco(this.usuario.cep).subscribe(success -> {
         this.usuarioService.salvar().subscribe();
  }, error -> {
         fazerAlgumaCoisa();
  });

}

pegarEndereco: any(cep: string){
  return this.cepService.buscarPorCep(cep);
}
