Real-time applications have become essential for organizations and developers in today's frantic
digital world.
Whether it's for social media, online gaming, or corporate communication, users want real-time
information, interactive features, and teamwork. But to create such applications, you need the
necessary technology and tools.
In this blog, we will look at the powerful SignalR and Vue.js combination to build real-time apps.
Why Are Real-Time Applications Required?
Let's first examine the importance of real-time applications, In the present era before delving into
the technical details.
1. Instantaneous communication
Users can instantaneously communicate with each other via real-time applications. For
messaging apps, customer support, and collaborative workspaces in particular, this is
crucial.
2. Live Updates
Live updates are provided by real-time apps, enabling users to view changes as they take
place. This is useful for news websites, social media, and stock trading systems.
3. Interactive Features
To keep users interested, live polls, online gaming, and auctions all rely on in-the-moment
interactions.
4. Productivity and Efficiency
Real-time apps in the workplace increase productivity by facilitating real-time document
editing, video conferencing, and distant collaboration.
5. Competitive Advantage
Businesses that offer real-time functionality have an advantage over their rivals since
customers frequently favor programs that offer quick responses.

2. Introduction to SignalR
Microsoft created the real-time communication library SignalR for.NET programs. It makes it
easier to include real-time capabilities in online applications. SignalR is a recommended option
for developing real-time functionality in .NET-based applications since it integrates effortlessly
with ASP.NET.
SignalR is adaptable and supports many communication methods, such as:
1. Web-Sockets
Full-duplex communication is available via WebSockets over a solitary, durable
connection.
2. Server-Sent Events (SSE)
To deliver changes from the server to the client, a unidirectional link is provided through
server-sent events (SSE).
3. Long Polling
This technique repeatedly checks the server for changes to simulate real-time
communication.
4. Azure SignalR Service
An easily scalable managed service for SignalR applications.
SignalR's ease of use and support for multiple transport mechanisms make it a go-to choice for
developers who need real-time application functionality.
Integrating SignalR into the Application
You must adhere to a few fundamental procedures to integrate SignalR into your application:
1. Set Up Your Environment: Start a brand-new project with the appropriate .NET
framework (for example, .NET Core or .NET 5+). You can use NuGet to install the SignalR
library.
2. Hub Creation: Construct a SignalR hub to be the focal point for in-the-moment
conversation. The management of connections, events, and message broadcasting is

3. done by .NET classes called hubs.
3. Client-side Integration: Include the SignalR client libraries in your Vue.js project. From your
Vue.js application, establish a connection to the hub on the server.
4. Server-side Method: Define server-side methods in the hub to deal with client requests
and send out notifications to clients.
5. Utilize SignalR client methods in your Vue.js application to Call Server Methods.

4. Role of Vue.js
Let’s investigate the role of Vue.js:
Function of Vue.js
Vue.js is an effective JavaScript framework for creating user interfaces, also known as Vue.
It is renowned for being straightforward, adaptable, and responsive which makes it a great option
for real-time online applications.
Real-time functionality can be implemented simply and seamlessly by combining SignalR with
Vue.js.
Real-Time Application Development with SignalR and Vue.js
Let's go over a straightforward example to see how SignalR and Vue.js collaborate to provide a
real-time chat application.
You can better comprehend the fundamental ideas and procedures involved in creating real-time
applications by using this example.
Make sure you have the following conditions met before starting:
● Installation of Node.js and npm for controlling Vue.js apps.

5. ● The SignalR server requires.NET Core or.NET 5+.
● A development-oriented code editor like Visual Studio Code or Visual Studio.
Now, let’s start with the process:

6. 1. Setting up the SignalR Server is the first step. Dot(.)NET Core or .NET 5+ projects should be
created first.
2. Apply NuGet to install the SignalR package:
"dotnet add package Microsoft.AspNetCore."SignalR '''
3. Establish a SignalR hub for real-time communication.
Here's an easy illustration:
Step 1:```csharp(C#)
using Microsoft.AspNetCore.SignalR;
public class ChatHub: Hub
{
public async Task SendMessage(string user, string message)
{
await Clients.All.SendAsync("ReceiveMessage", user, message);
}
}
```
Step 2: Vue.js Frontend
1. Create a new Vue.js project:
```
vue create real-time-chat-app
```
2. Install the SignalR client library for Vue.js:
```
npm install @microsoft/signalr

7. ```

8. 3. Implement the chat functionality in your Vue.js component:
```Vue
<template>
<div>
<div>
<input v-model="user" placeholder="Username" />
<input v-model="message" @keyup.enter="sendMessage" placeholder="Type a
message" />
</div>
<div>
<div v-for="(msg, index) in messages" :key="index">
{{ msg.user }}: {{ msg.text }}
</div>
</div>
</div>
</template>
<script>
import * as signalR from "@microsoft/signalr";
export default {
data() { return
{
user: "",
message: "",
messages: [],
};
},

9. created() {
this.connection = new signalR.HubConnectionBuilder()
.withUrl("/chatHub")
.build();
this.connection.on("ReceiveMessage", (user, message) => {
this.messages.push({ user, text: message });
});
this.connection.start().catch((err) => console.error(err));
},
methods: {
sendMessage() {
this.connection.invoke("SendMessage", this.user, this.message);
this.message = "";
},
},
};
</script>
```
Step 3: Running the Application
1. Start the SignalR server:
```
dotnet run
```
2. Start the Vue.js development server:
```
npm run serve

10. ```
Now, open your browser and navigate to the Vue.js application (usually http://localhost:8080).
You should be able to chat with other users in real time.
This example shows how to integrate SignalR and Vue.js fundamentally to build a real-time chat
application. But there are countless options. On top of this framework, you may add more
intricate real-time features like live notifications, group document editing, and interactive online
games.
Real-Time Application Best Practices
It might be difficult to create real-time apps, so it's crucial to adhere to several best practices:
1. Scalability: To manage growing traffic, use the Azure SignalR Service or other scalable
alternatives.

11. 2. Safety: Implement systems for authentication and permissions to safeguard your
real-time software.
3. Error Handling: Handle mistakes compassionately to keep the user experience positive.
4. Testing: To ensure dependability and performance, thoroughly test your real-time
features.

12. 5. Monitoring and Analytics: Use monitoring and analytics tools to keep tabs on how your
real-time application is being used and performing.
6. Optimization: Make your application more resource and data-transfer efficient.
To Sum Up!
When creating real-time applications, SignalR and Vue.js are a potent combination. Real-time
communication is more easily implemented on the server side using SignalR, while the front
end is made more user-friendly and responsive with Vue.js. They enable programmers to make
interesting and interactive online applications that satisfy users' needs today.
The example given in this blog post is merely the beginning. Real-time applications are
