Error: Provider not recognized

Currently, I am in the process of creating a basic chat application using express.js, socket.io, and angular. The functionality seems to be working properly. However, I am encountering an issue where the socket message event is not synchronizing and displaying on the page correctly.

 var socket = io.connect('http://localhost:8080');



angular.module('chat',[]).controller('chatController',['$scope','$apply',function($scope,$apply){
    chat = $scope;
    chat.messages = [];

    socket.on('messages',function(data){
        chat.$apply(function(){
            chat.messages.push(data);
        });
    });
}])

I understand that I need to use `$apply` in some way, but I keep receiving an error mentioning an unknown provider. Can someone guide me on the correct approach to implementing $apply?

Answer №1

Avoid the necessity of passing $apply as a dependency,

Give this approach a shot:

angular.module('chat',[]).controller('chatController',['$scope',function($scope){
     $scope.messages = [];
     socket.on('messages',function(data){
         $scope.$apply(function(){
             $scope.messages.push(data);
        });
    });
}])
