streamjsonrpc c# (How It Works For Developers)

Introduction

Using the JSON-RPC protocol, StreamJsonRpc in C# enables effective communication between clients and servers across various transport levels. With the help of this library, remote procedure calls can be implemented more easily, allowing developers to create reliable distributed systems in which programs can call methods on distant servers just like they would locally. By allowing dynamic PDF creation based on data transferred through JSON-RPC requests, StreamJsonRpc improves application capabilities when used with IronPDF, a complete .NET Framework for PDF generation and manipulation. For developers looking to streamline the process of creating customized reports, invoices, or any document-centric application that needs to generate PDFs on demand, this interface is quite helpful.

IronPDF gives developers flexibility and efficiency in organizing and delivering content by supporting the conversion of HTML, ASPX, and raw data into high-quality PDF publications. StreamJsonRpc and IronPDF work together to enable C# developers to build responsive, scalable apps that easily combine complex PDFs with remote procedure calls.

What is StreamJsonRpc?

StreamJsonRpc is a cross-platform library designed for facilitating remote procedure calls (RPC) using a lightweight and efficient wire protocol. It utilizes an underlying transport mechanism that supports various communication channels such as TCP/IP, named pipes, and HTTP. The library leverages .NET events for handling incoming requests and responses, providing a robust mechanism for asynchronous communication. Developers can attach method implementations to handle RPC requests and define custom behaviors using the StreamJsonRpc API. StreamJsonRpc is available as a .NET Portable Library, ensuring compatibility across different platforms and enabling seamless integration into diverse .NET applications.

A strong support for bidirectional communication, including notifications and progress reporting, is one of StreamJsonRpc's key characteristics. By supporting various transport protocols including HTTP, Named Pipes, and TCP/IP, it gives programs more communication options. JSON-RPC message serialization and deserialization are handled by StreamJsonRpc, guaranteeing compatibility across many platforms and JSON-supporting computer languages.

StreamJsonRpc was designed with performance and extensibility in mind. It is compatible with existing C# programs and may be used to construct client-server applications, microservices architectures, distributed systems, and other applications where dependable and efficient communication is crucial. When integrating remote procedure calls into C# projects, developers tend to choose it because of its dependability and ease of use.

Features of StreamJsonRpc

A comprehensive collection of functionality is provided by C#'s StreamJsonRpc, which is intended to facilitate and improve JSON-RPC protocol-based client-server application communication.

Remote Procedure Calls (RPC)

By considering remote operations as though they were local function calls, StreamJsonRpc enables clients to call methods on a server via remote procedure calls. By disguising the intricacies of network communication, this abstraction makes the creation of distributed applications easier.

Bidirectional Communication

Bidirectional client-server communication is supported by the library. Real-time communication and updates are made possible by the ability for clients to submit requests to servers, which in turn can reply with notifications or results.

Transport Layer Agnosticism

Because it is transport layer agnostic, StreamJsonRpc can function over a variety of transport protocols, including HTTP, Named Pipes, and TCP/IP. Because of this adaptability, developers can select the best transport method according to the needs of their applications and the network settings.

Serialization and Deserialization

It manages JSON-RPC message serialization and deserialization, guaranteeing smooth communication across various platforms and JSON-capable computer languages.

Progress Reporting

Progress reporting techniques are supported by StreamJsonRpc for long-running activities. This feature improves user experience and transparency by enabling servers to update clients on the status of current processes.

Error Handling

To handle exceptions and problems that arise during the invocation of remote methods, the library has extensive error-handling features. This guarantees dispersed systems' resilience and dependability.

Extension Points

StreamJsonRpc can be extended by developers to alter its functionality or include it with already existing application architectures. Because of its versatility, it may be tailored to meet a variety of integration needs and application scenarios.

Performance Optimization

Through effective custom message handling and transport layer management, StreamJsonRpc maximizes throughput in client-server communication while guaranteeing low overhead.

Asynchronous Support

Through the use of asynchronous operations, it enables applications to achieve improved responsiveness and scalability. It completely supports asynchronous communication patterns.

Interoperability

Through conformance to the JSON-RPC standard, StreamJsonRpc facilitates smooth integration in diverse contexts by fostering interoperability between C# applications and services built in other languages that support JSON.

Along with these main features, there are some bonus features past the JSON-RPC spec which includes features such as support for compact binary serialization and dynamic client proxy.

MyService Class: Specifies the methods that the client can call remotely, such as AddAsync and GreetAsync.

This starts a new JsonRpc instance, initializes MyService, and configures a WebSocket message handler to listen at ws://localhost:8080. The server exposes MyService as a new local RPC target and begins to wait for JSON-RPC queries to arrive. Presses a key to stop listening and discards resources.

Client Configuration

Make a class that will function as the client for JSON-RPC. Observe this simple example:

using StreamJsonRpc;
using System;
using System.Threading.Tasks;
class Program
{
    static async Task Main(string[] args)
    {
        var proxy = new JsonRpc(new ClientWebSocketJsonRpcMessageHandler("ws://localhost:8080"));
    // client proxy
        await proxy.StartListeningAsync();
        var resultAdd = await proxy.InvokeAsync<int>("AddAsync", 10, 20);
        Console.WriteLine($"AddAsync result: {resultAdd}");
        var resultGreet = await proxy.InvokeAsync<string>("GreetAsync", "John");
        Console.WriteLine($"GreetAsync result: {resultGreet}");
        proxy.Dispose();
    }
}

using StreamJsonRpc;
using System;
using System.Threading.Tasks;
class Program
{
    static async Task Main(string[] args)
    {
        var proxy = new JsonRpc(new ClientWebSocketJsonRpcMessageHandler("ws://localhost:8080"));
    // client proxy
        await proxy.StartListeningAsync();
        var resultAdd = await proxy.InvokeAsync<int>("AddAsync", 10, 20);
        Console.WriteLine($"AddAsync result: {resultAdd}");
        var resultGreet = await proxy.InvokeAsync<string>("GreetAsync", "John");
        Console.WriteLine($"GreetAsync result: {resultGreet}");
        proxy.Dispose();
    }
}

This example establishes a connection to ws://localhost:8080 to start a JsonRpc instance with a WebSocket message handler. It then enables the AddAsync and GreetAsync methods that are defined on the server (MyService) by establishing a connection with the JSON-RPC server. Finally, it shows the outcomes that the server has returned and releases the resources after the RPC calls are finished.

The PdfService.cs class is a fundamental part of a StreamJsonRpc server implementation that makes it easier for a C# application to generate PDF documents using IronPDF. By utilizing IronPDF's RenderHtmlAsPdf, this service class contains methods for handling the conversion of HTML material into PDF format. HTML content is accepted as input via the GeneratePdfAsync method, which is designated as asynchronous (async Task GeneratePdfAsync(string htmlContent)).

This method creates an instance of HtmlToPdf to carry out the conversion, producing a PDF document with RenderHtmlAsPdf(htmlContent). The created PDF's binary data is then retrieved asynchronously by the method (pdf.BinaryDataAsync()), which subsequently returns the data as a byte[] array.

This method guarantees quick and responsive PDF generation, making it appropriate for applications that need to create documents quickly. The PDF generation logic is contained in PdfService.cs, which makes it simple for developers to integrate and expose this functionality over StreamJsonRpc. This allows distant clients to smoothly invoke PDF generation jobs while preserving the modularity and clarity of their server-side design.

Conclusion

To sum up, developers may create reliable and effective .NET apps that support remote procedure calls (RPC) and make use of strong PDF production capabilities by combining StreamJsonRpc with IronPDF. Using JSON-RPC, a lightweight protocol for remote procedure calls, StreamJsonRpc enables smooth communication between client and server components. Developers can use this in conjunction with IronPDF to generate dynamic, data-driven PDFs that are dependent on the outcomes of these remote calls.

When preparing reports, invoices, or any other document that must represent the most recent data available, this integration is very helpful as it allows for real-time data retrieval and PDF output. The integration of these technologies optimizes the development process, boosts performance, and strengthens the application's capacity to effectively satisfy intricate business needs.

With IronPDF and the IronSoftware Development Tools, developers can create more web apps and features more quickly, all for a starting price of $749. It accomplishes this by fusing its core concepts with the immensely flexible Iron Software toolbox.

Developers will find it easier to select the optimal model if all license options relevant to the project are clearly described. The benefits listed above make it easier for developers to create solutions for a range of issues in a timely, coordinated, and efficient manner.
