In my AngularJS app I have a service that is based on WebSocket. If the WebSocket connection breaks, I want to fully 'restart' the application (go to default page from $route, recreate the service etc.). Is that achievable? This is how I started, but from that point I have no idea how to proceed:
Module:
(function () {
angular.module('mainModule', ['ngRoute'])
.config(['$routeProvider', function ($routeProvider) {
$routeProvider.
when('/home', {
templateUrl: 'partials/home.html',
controller: 'appController'
}).
when('/register', {
templateUrl: 'partials/register.html',
controller: 'appController'
}).
otherwise({
redirectTo: '/home'
});
}]);
}());
Service:
(function () {
var app = angular.module('mainModule');
app.service('$wsService', ['$q', '$window', function ($q, $window) {
$window.console.log("WebSocket SERVICE: started");
var self = this;
var ws = new WebSocket("ws://127.0.0.1:9090");
this.isConnected = function (m) {};
ws.onopen = function () {
$window.console.log("WebSocket SERVICE: connected");
self.isConnected(true);
};
ws.onmessage = function (m) {
//do whatever I want to do
};
ws.onerror = function () {
$window.console.log("WebSocket SERVICE: disconnected");
self.isConnected(false);
};
}]);
}());
Controller:
(function () {
var app = angular.module('mainModule');
app.controller('appController', ['$route', '$scope', '$wsService', function ($route, $scope, $wsService) {
$wsService.isConnected = function (m) {
//restart logic
};
}]);
}());
So as my 'restart logic' I tried "$route.reload();" but as you already know it doesn't do what I need. Eventually I will have a warning message pop up (bootstrap modal) informing the user that the connection has been lost, and on a button click in that modal it will reload the app and go to /home. I am not asking how to do that popup etc as this is already done. As for now however, I need to figure out just the logic for total reload of the app. Any ideas? Thanks.
reload() method is used to refresh or reload the entire page, optionally forcing a re-download of the content.
To answer my own question, achieved with a trial and error:
$scope.$apply(function() {
$location.path('/home');
$window.location.reload();
});
This will go to /home (default) and reload everything, thus creating new service, module, controllers etc. If there is a better way of doing it (if I change default path to /blah in my module, this won't pick it up and thus I will have to edit this code too), let me know :)
I achieved the same thing doing:
$window.location.href = '/home';
A little tweak I did to your answer that helped a lot with the UI refreshing. Is to do the path change inside the reload success callback:
$window.location.reload().then(
function success(){
$location.path('/home');
},
function error(error) {}
);
Most of the time it gives a very smooth transition, presuming you are restarting while redirecting to a different page.
