Create and Configure Grapevine C\

Setting up the development environment, installing required packages, and configuring the Grapevine framework are some of the stages involved in creating and configuring a Grapevine C# project. Here's a step-by-step tutorial to get you started:

Create a New .NET Project

1. Open a command prompt or terminal.
2. Launch a newly created .NET console application by typing:

dotnet new console -n GrapevineExample
cd GrapevineExample

dotnet new console -n GrapevineExample
cd GrapevineExample

Install Grapevine

1. Add the Grapevine package to your project:

dotnet add package Grapevine

dotnet add package Grapevine

Configure Grapevine

using Grapevine;
using Grapevine.Interfaces.Server;
using Grapevine.Server;
using Grapevine.Server.Attributes;
using Grapevine.Shared;

public class Program
{
    public static void Main(string[] args)
    {
        // Create and start a new REST server
        var server = new RestServer();
        server.Start();
        Console.WriteLine("Server is running...");
        Console.WriteLine("Press enter to stop the server.");
        Console.ReadKey();
        server.Stop();
    }
}

[RestResource]
public class SampleResource
{
    // Defines a route method for the /hello endpoint
    [RestRoute(HttpMethod = HttpMethod.GET, PathInfo = "/hello")]
    public IHttpContext HelloWorld(IHttpContext context)
    {
        // Send a response for the GET request at /hello
        context.Response.SendResponse("Hello, World!");
        return context;
    }
}

using Grapevine;
using Grapevine.Interfaces.Server;
using Grapevine.Server;
using Grapevine.Server.Attributes;
using Grapevine.Shared;

public class Program
{
    public static void Main(string[] args)
    {
        // Create and start a new REST server
        var server = new RestServer();
        server.Start();
        Console.WriteLine("Server is running...");
        Console.WriteLine("Press enter to stop the server.");
        Console.ReadKey();
        server.Stop();
    }
}

[RestResource]
public class SampleResource
{
    // Defines a route method for the /hello endpoint
    [RestRoute(HttpMethod = HttpMethod.GET, PathInfo = "/hello")]
    public IHttpContext HelloWorld(IHttpContext context)
    {
        // Send a response for the GET request at /hello
        context.Response.SendResponse("Hello, World!");
        return context;
    }
}

Imports Grapevine
Imports Grapevine.Interfaces.Server
Imports Grapevine.Server
Imports Grapevine.Server.Attributes
Imports Grapevine.Shared

Public Class Program
	Public Shared Sub Main(ByVal args() As String)
		' Create and start a new REST server
		Dim server = New RestServer()
		server.Start()
		Console.WriteLine("Server is running...")
		Console.WriteLine("Press enter to stop the server.")
		Console.ReadKey()
		server.Stop()
	End Sub
End Class

<RestResource>
Public Class SampleResource
	' Defines a route method for the /hello endpoint
	<RestRoute(HttpMethod := HttpMethod.GET, PathInfo := "/hello")>
	Public Function HelloWorld(ByVal context As IHttpContext) As IHttpContext
		' Send a response for the GET request at /hello
		context.Response.SendResponse("Hello, World!")
		Return context
	End Function
End Class

The first step involves importing the required namespaces from the Grapevine library to aid in HTTP request handling, routing, and server operations. The Main function in the Program class creates and launches a RestServer object that listens 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, marked with the [RestResource] attribute, which also designates the HelloWorld function that responds to GET requests made at the /hello location.

Upon a successful hit on the endpoint, the HelloWorld 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 where 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:

A PdfResource class is defined in the Grapevine configuration to manage specific HTTP requests associated with PDF creation. The [RestResource] attribute, when present, indicates that this class has methods that can respond 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 ChromePdfRenderer.
• A byte array (pdfBytes) is created from the final PDF document.
• The HTTP context (context) is set up to reply with a PDF content type, and it uses SendResponse to transmit the PDF byte array back to the client.
