Meteor + React + Mantra: Use LocalState to pass action result to a component?

help
1

Hi guys, I’m using the LocalState to send back actions result to a component and I’m wondering if it’s the good way to do that.

Action:

Meteor.call('flats.search', params, (err, flats) => {

  if (err) {
    LocalState.set('SEARCH_FLAT_ERROR', err.message);
    LocalState.set('FLAT_RESULT', NO_FLAT_FOUND);
    return null;
  }

  LocalState.set('FLAT_RESULT', flats);
});

Container:

const flats = LocalState.get('FLAT_RESULT') ? LocalState.get('FLAT_RESULT') : []; onData(null, {errorMessages, flats});

Component:

const {flats} = this.props;
{flats.map( (flat, idx) => (
   ....
 )}

Is there a better way to do that, if yes please help me !!

Thanks

This topic is bit old but actual in my case. Is this way of getting data is recommended?

Hi @mipasov, Using the LocalState is actually the recommended pattern as pointed in Mantra specifications.

Hi @ngouana ,

I have little difficulties in realizing this in my code.
In my container I am subscribing to some data and passing data trough onData() . Could you please give some hints, how to pass data which set through actions again by onData(), on same container?

Something like:

container: 
subscribe to publication.
  if no error
     onData(null,{data})

actions:
   call method
      if no error
         LocalState.set('DATA',data);


on same container: 
  const data=LocalState.get('DATA');  
\\how it will be possible to pass data ?

Regards,
Mirlan
