How ASP.NET SignalR reduces Client's Waiting Period?
As a server-side software system, SignalR is used widely by ASP.NET developers to add real-time web functionality to their applications. The term real-time web functionality refers to the ability to push content from the server to connected clients as soon as the data becomes available. The functionality does not require the web server to wait till the client requests new data. Thus, ASP.NET SignalR used effectively to reduce the client’s waiting period.
Often users refresh web pages with the intention of seeing new and updated data. Each time a web page is refreshed or try to retrieve updated data by implementing long polling, the developers can use Signal R to reduce the waiting time. SignalR further makes it easier for programmers to build applications that need high frequency updates from the server, including collaborative applications, dashboards, real-time forms and real-time games.
Features that Make ASP.NET SignalR Effective in Reducing Client's Waiting Period
Selects the Best Available Transport Automatically
ASP.NET SignalR reduces the client’s waiting time by taking advantage of multiple transportations. It evaluates the best available transport of both server and client, and chooses the best one. At the same time, it also avails the benefits of WebSockets to enable bidirectional communication between the browser and server. However, SignalR relies on the HTML5 API only when it is available. If WebSockets is not available, it uses techniques to facilitate bidirectional communication. The programmers are not required to write specific or additional code to choose the best transportation.
Provides a High-Level API to Create Server-to-Client RPCs
The users can further create server-to-client remote procedure calls (RPC) by using the high-level API provided by SignalR. It uses ASP.NET code from server-side, and calls JavaScript functions in the web browser or any other platform of the client. At the same time, SignalR also allows programmers to smoothly manage connections by adding a variety of hooks, including grouping connections, authorization, and connect or disconnect events.
Facilitates Long and Consistent Polling
Normally, polling consists of making periodic connections from the client to server with the intention of checking if any relevant update to the server content. Some applications like chat programs frequently poll the server to deliver updated data to users. Some application requiring high frequency data often open a connection and keep it open. SignalR uses WebSockets to facilitate long and consistent polling. So the programmers are not required to write complex code to keep the connection open.
Pushes Data Effectively to a Variety of Clients
Often developers have to explore ways to reduce the overhead on server. Some programmers even add capabilities to the server to reduce the overhead by notifying the clients about any updates. They also use a variety of technologies to reduce the server overhead including WebSockets, long polling and Server Sent Events (SSE). But these techniques are not supported by all clients and web browsers. On the other hand, SignalR is designed as an ASP.NET library that uses the existing and available transport technologies. So it is effective in pushing data to a variety of clients including web pages, web applications and Window Phone Apps.
Helps in Building Asynchronous Applications
SignalR is used widely by programmers as a framework to create asynchronous applications. The framework makes it easier for them to build ASP.NET applications by overcoming the limitations of the response and request cycle of internet communication. They can further move to conventional one-on-one connection offered by the conventional client server architectures to push the content quickly from the web server to the client.
Despite being effective in reducing client’s waiting period, ASP.NET SignalR is simple and easy to implement. That is why; many developers rely on the efficient library to rapidly build applications that poll the server constantly to provide updated information to users.
