By enabling smooth PDF creation and manipulation within your online services, combining Grapevine and IronPDF can greatly improve your C# web applications. This connection provides an effective way to create invoices, reports, or any other kind of document.

What is Grapevine C#?

A lightweight, quick, and adaptable RESTful web service and API can be created with the help of Grapevine, a C# micro web framework. It is perfect for tiny projects, prototypes, and microservices that need to handle HTTP requests efficiently because of its use of simple patterns and basic architecture, which guarantees fast setup and great performance.

Grapevine makes the process of identifying and managing endpoints easier by providing a flexible and user-friendly routing mechanism. It makes it easier to create CRUD operations and well-organized RESTful APIs by supporting a number of HTTP methods, including GET, POST, PUT, and DELETE. It also supports middleware, which enables programmers to add more functionality by creating unique components for logging, authentication, and error handling.

Because the framework follows REST concepts, developers can create scalable and reliable APIs. Because of its simplicity and ease of use, it's a great option for developers who need to quickly prototype and launch web services without having to deal with the complexities of larger frameworks. Because of its lightweight design, Grapevine is appropriate for microservices and apps that don't need the overhead of a complex web framework.

The first step involves importing the required namespaces from the Grapevine library, which helps with HTTP request handling, routing, and server operations. The Main function in the Program class creates and launches a RestServer object. This server keeps an eye out for new HTTP requests.

The user is informed via the console that the server is up and running and will terminate if any key is pressed. An endpoint is defined by the SampleResource class, which is identified by the [RestResource] attribute, here you could also use a method like public async task test to ensure smooth response times. The [RestRoute] attribute designates the HelloWorld function, which responds to GET requests made at the /hello location. The following output shows the result of this.

Upon successfully hit on the endpoint, the method uses the IHttpContext parameter to return a "Hello, World!" response to the client, along with details about the HTTP request and response. This simple configuration demonstrates how to build a single-route, lightweight web server, highlighting Grapevine's user-friendly HTTP request handling in C#.

Getting Started

Setting up a project in which you can use Grapevine to establish RESTful web services and IronPDF to create or modify PDF documents is the first step in getting started with Grapevine and IronPDF in C#. Here's a step-by-step tutorial to get you going:

Grapevine With IronPDF

In order for your first server to handle HTTP requests and responses within the program, a Grapevine RestServer instance must be initialized. This is done by running the Program.cs file. Using the rest servers, the server is launched.Start() and stop, as the server indicated, when pressing any key.Pause().

using Grapevine.Interfaces.Server;
using Grapevine.Server.Attributes;
using Grapevine.Server;
using Grapevine.Shared;
using IronPdf;
class Program
{
    [RestResource]
    public class PdfResource
    {
    //Route methods
        [RestRoute(HttpMethod = Grapevine.Shared.HttpMethod.GET, PathInfo = "/generate-pdf")]
        public IHttpContext GeneratePdf(IHttpContext context)
        {
            var htmlContent = "<h1>Hello, PDF!</h1><p>This is a PDF generated using IronPDF.</p>";
            var renderer = new ChromePdfRenderer();
            var pdf = renderer.RenderHtmlAsPdf(htmlContent);
            var pdfBytes = pdf.BinaryData;
            context.Response.ContentType = ContentType.CUSTOM_BINARY;
            context.Response.ContentLength64 = pdfBytes.Length;
            context.Response.SendResponse(pdfBytes);
            return context;
        }
    }
    static async Task Main(string[] args)
    {
        var server = new RestServer();
        server.LogToConsole().Start();
        Console.WriteLine("Server is running...");
        Console.WriteLine("Press any key to stop the server.");
        Console.ReadKey();
        server.Stop();
    }
}

using Grapevine.Interfaces.Server;
using Grapevine.Server.Attributes;
using Grapevine.Server;
using Grapevine.Shared;
using IronPdf;
class Program
{
    [RestResource]
    public class PdfResource
    {
    //Route methods
        [RestRoute(HttpMethod = Grapevine.Shared.HttpMethod.GET, PathInfo = "/generate-pdf")]
        public IHttpContext GeneratePdf(IHttpContext context)
        {
            var htmlContent = "<h1>Hello, PDF!</h1><p>This is a PDF generated using IronPDF.</p>";
            var renderer = new ChromePdfRenderer();
            var pdf = renderer.RenderHtmlAsPdf(htmlContent);
            var pdfBytes = pdf.BinaryData;
            context.Response.ContentType = ContentType.CUSTOM_BINARY;
            context.Response.ContentLength64 = pdfBytes.Length;
            context.Response.SendResponse(pdfBytes);
            return context;
        }
    }
    static async Task Main(string[] args)
    {
        var server = new RestServer();
        server.LogToConsole().Start();
        Console.WriteLine("Server is running...");
        Console.WriteLine("Press any key to stop the server.");
        Console.ReadKey();
        server.Stop();

A PdfResource class is defined in the Grapevine configuration to manage particular HTTP requests associated with PDF creation. The [RestResource] attribute, when present, indicates that this class has methods that can react to RESTful routes.

The [RestRoute(HttpMethod = HttpMethod.GET, PathInfo = "/generate-pdf")] annotation on the GeneratePdf method within PdfResource indicates that this method responds to GET requests at the /generate-pdf endpoint. Within the procedure:

• The content that will be turned into a PDF is represented by an HTML content string (htmlContent), which is defined.
• A PDF document (pdf) is created from the HTML text using IronPDF's HtmlToPdf class (renderer).
• A byte array (pdfBytes) is created from the final PDF document.
• After that, the HTTP context (context) is set up to reply with a PDF content type, and it uses context to transmit the PDF byte array back to the client reaction output at SendResponse.

Conclusion

In conclusion, developers wishing to incorporate web service capabilities with dynamic PDF production within their applications will find a solid solution in the integration of Grapevine C# with IronPDF. The setup and implementation of RESTful endpoints is made simpler by Grapevine's lightweight and user-friendly minimalist web framework, which also makes it simple to have code to process HTTP requests and create custom routes. IronPDF, on the other hand, improves the program by enabling the easy conversion of HTML information into excellent PDF documents, which include JavaScript integration and support for CSS styling.

This connection gives developers the ability to create dynamic, professional-looking PDFs and distribute them, all while making it easier to create interactive, data-driven web services. Together, Grapevine and IronPDF provide a flexible toolbox that satisfies the needs of contemporary online application development, whether for producing reports, invoices, or other document kinds. Through the combination of IronPDF's robust PDF creation capabilities and Grapevine's user-friendly interface, developers can create scalable and effective solutions that meet a wide range of user requirements and corporate goals.
