What is the SignalR?
If I have to explain it very briefly: SignalR is a library developed by Microsoft and used to build real-time web applications.
The Ecosystem
Real-time applications, also called “Real-Time Web” or “WebSockets”, refer to applications that need instant communication between server and client. For example, SignalR can be used in scenarios such as an online chat application, push notifications, live data updates.
SignalR is a server-side library that can communicate with clients from web browsers, mobile devices or other platforms. SignalR automatically selects the most appropriate communication mechanism to ensure compatibility between different browsers and devices.
What is the worker service?
I gave the link to my detailed article on this subject at the beginning of the article. But still, to mention it briefly: Worker Service is a framework for creating applications that run continuously in the background and perform long-running operations. These operations can be tasks, database operations, file operations or other processes that are usually run from time to time.
We have defined our definitions!
How can we combine these two?
By using SignalR and Worker Service together, it is possible to create applications that need real-time data processing and updates. For example, when a Worker Service running in the background on a system regularly performs a specific task, the results of this task can be instantly sent to web browsers or other clients with SignalR. Thus, users can follow the real-time status of the system or receive push notifications.
Our scenario is a stock price tracking application: A Worker Service running in the background will periodically update stock prices and store them in a database. Using SignalR, these updated stock prices are transmitted to web browsers in real time and users can instantly see the current stock prices.
In this very simple project, I have tried to explain the SignalR and worker service combination. It is up to your imagination to configure this duo according to your needs.
