Is Meteor.status() considered a non-reactive data source?

We are currently working on a feature to display the connection status in our app:

this.helpers({
    userBlock: () => {
        //...
        return {
            name: name,
            connectionStatus: Meteor.status().connected
        }
    }
});

Unfortunately, we are facing an issue where the helper does not re-run after the server is disconnected. Even outputting the Meteor.status().connected variable directly into the template using both $scope and controller reference does not reflect any updates. Are there any suggestions on how we can make the helper re-run when there is a change in Meteor.status().connected?

Answer №1

I successfully implemented the functionality, which functions as intended. In case of server downtime, the template displays a "Disconnected" message, and this message disappears once the server is back online.

var CONNECTION_ISSUE_FLAG = 'connectionIssue';
Session.setDefault(CONNECTION_ISSUE_FLAG, false);

Meteor.startup(function () {

   // Display the connection error box only after 5 seconds
   setTimeout(function () {
       Session.set(CONNECTION_ISSUE_FLAG, true);
   }, 5000);
});

Template.header.helpers({
   connected: function() {
       if (Session.get(CONNECTION_ISSUE_FLAG)) {
           return Meteor.status().connected; 
       } else {
           return true;
       }
}});

In the template:

{{#unless connected}}
        <div class="alert alert-danger">
            Disconnected
        </div>
{{/unless}}
