AngularJS SignalR with AngularJs SignalR And AngularJs [ ChatProject ]
Example
step 1: Create Project
- Application
- app.js
- Controllers
- appController.js
- Factories
- SignalR-factory.js
- index.html
- Scripts
- angular.js
- jquery.js
- jquery.signalR.min.js
- Hubs
SignalR version use: signalR-2.2.1
Step 2: Startup.cs And ChatHub.cs
Go to your "/Hubs" directory and Add 2 files [Startup.cs, ChatHub.cs]
Startup.cs
using Microsoft.Owin;
using Owin;
[assembly: OwinStartup(typeof(SignalR.Hubs.Startup))]
namespace SignalR.Hubs
{
public class Startup
{
public void Configuration(IAppBuilder app)
{
app.MapSignalR();
}
}
}
ChatHub.cs
using Microsoft.AspNet.SignalR;
namespace SignalR.Hubs
{
public class ChatHub : Hub
{
public void Send(string name, string message, string time)
{
Clients.All.broadcastMessage(name, message, time);
}
}
}
step 3: create angular app
Go to your "/Application" directory and Add [app.js] file
app.js
var app = angular.module("app", []);
step 4: create SignalR Factory
Go to your "/Application/Factories" directory and Add [SignalR-factory.js] file
SignalR-factory.js
app.factory("signalR", function () {
var factory = {};
factory.url = function (url) {
$.connection.hub.url = url;
}
factory.setHubName = function (hubName) {
factory.hub = hubName;
}
factory.connectToHub = function () {
return $.connection[factory.hub];
}
factory.client = function () {
var hub = factory.connectToHub();
return hub.client;
}
factory.server = function () {
var hub = factory.connectToHub();
return hub.server;
}
factory.start = function (fn) {
return $.connection.hub.start().done(fn);
}
return factory;
});
step 5: update app.js
var app = angular.module("app", []);
app.run(function(signalR) {
signalR.url("http://localhost:21991/signalr");
});
localhost:21991/signalr | this is your SignalR Hubs Urls
step 6: add controller
Go to your "/Application/Controllers" directory and Add [appController.js] file
app.controller("ctrl", function ($scope, signalR) {
$scope.messages = [];
$scope.user = {};
signalR.setHubName("chatHub");
signalR.client().broadcastMessage = function (name, message, time) {
var newChat = { name: name, message: message, time: time };
$scope.$apply(function() {
$scope.messages.push(newChat);
});
};
signalR.start(function () {
$scope.send = function () {
var dt = new Date();
var time = dt.getHours() + ":" + dt.getMinutes() + ":" + dt.getSeconds();
signalR.server().send($scope.user.name, $scope.user.message, time);
}
});
});
signalR.setHubName("chatHub") | [ChatHub] (public class) > ChatHub.cs
Note: do not insert HubName with upper Case, first letter is lower Case.
signalR.client() | this method try to connect to your hubs and get all functions in the Hubs, in this sample we have "chatHub", to get "broadcastMessage()" function;
step 7: add index.html in route of directory
index.html
<!DOCTYPE html>
<html ng-app="app" ng-controller="ctrl">
<head>
<meta charset="utf-8" />
<title>SignalR Simple Chat</title>
</head>
<body>
<form>
<input type="text" placeholder="name" ng-model="user.name" />
<input type="text" placeholder="message" ng-model="user.message" />
<button ng-click="send()">send</button>
<ul>
<li ng-repeat="item in messages">
<b ng-bind="item.name"></b> <small ng-bind="item.time"></small> : {{item.message}}
</li>
</ul>
</form>
<script src="Scripts/angular.min.js"></script>
<script src="Scripts/jquery-1.6.4.min.js"></script>
<script src="Scripts/jquery.signalR-2.2.1.min.js"></script>
<script src="signalr/hubs"></script>
<script src="app.js"></script>
<script src="SignalR-factory.js"></script>
</body>
</html
Result with Image
User 1 (send and receive)
User 2 (send and receive)
