Web applications are kept fluid and adaptable with this integration, which enables effective resource management and dynamic PDF generation. WebGrease and IronPDF are fully compatible with .NET Core, allowing developers to create cross-platform applications that function flawlessly on Linux, macOS, and Windows. This results in an enhanced user experience thanks to optimized performance and superior document handling.

What is WebGrease?

Originally created as a component of the ASP .NET stack, WebGrease is a tool for automating processes such as optimizing JavaScript, compression, picture optimization, and CSS minification of static files in order to improve web performance. These optimizations contribute to the reduction of web resource sizes, which improves web application performance and speeds up load times.

In the context of .NET Core, when we discuss WebGrease, we mean the application of these optimization methods to .NET Core applications. Microsoft created the cross-platform, open-source .NET Core framework to let developers create cutting-edge, scalable, and high-performing apps. Developers can apply performance optimization techniques from traditional ASP.NET applications to their .NET Core projects by integrating WebGrease. This way, developers can make sure that their web applications are efficient and performant on various platforms, such as Windows, Linux, and macOS.

Features of WebGrease

Within the framework of .NET Core, WebGrease provides a number of capabilities targeted at enhancing the effectiveness and speed of web applications. The salient characteristics are as follows:

CSS Minification:

Eliminates extraneous formatting, comments, and whitespace from CSS files. Reduces HTTP requests by combining numerous CSS files into a single file. Enhances performance and speeds up loading times for CSS.

JavaScript Compression:

Minimizes JavaScript files by removing characters that aren't needed. Makes a single JavaScript file out of several separate ones. Minimizes JavaScript files' size to expedite download and execution times.

Image Optimization:

Reduces file size by compressing images without noticeably compromising quality. When appropriate, convert photos to more efficient formats. Increases loading speeds through image resource optimization.

HTML Minification:

Reduces the amount of whitespace and comments in HTML files. Simplifies HTML files so that browsers can parse and render them more quickly.

Resource Bundling:

Combines several JavaScript and CSS files into a single, streamlined file. Improves load times by lowering the quantity of HTTP requests required to get load file, get static files, and load a page.

Configuration Flexibility:

Offers choices for configuring the optimization process. Gives developers the option to choose which directories and files to optimize or leave out.

Cross-Platform Compatibility:

Completely compatible with .NET Core, enabling use in Windows, Linux, and macOS apps. Guarantees that performance improvements work well in a variety of settings.

Integrate IronPDF

Build a controller with IronPDF to produce PDFs. Create a new PdfController controller.

using Microsoft.AspNetCore.Mvc;
using IronPdf;
namespace WebGreaseIronPdfApp.Controllers
{
    public class PdfController : Controller
    {
        public IActionResult GeneratePdf()
        {
            // Create a PDF from a simple HTML string
            var renderer = new ChromePdfRenderer();
            var pdf = renderer.RenderHtmlAsPdf("<h1>Hello, IronPDF!</h1><p>This is a generated PDF document.</p>");
            // Save the PDF to a byte array
            var pdfBytes = pdf.BinaryData;
            // Return the PDF file as a download
            return File(pdfBytes, "application/pdf", "example.pdf");
        }()
}

using Microsoft.AspNetCore.Mvc;
using IronPdf;
namespace WebGreaseIronPdfApp.Controllers
{
    public class PdfController : Controller
    {
        public IActionResult GeneratePdf()
        {
            // Create a PDF from a simple HTML string
            var renderer = new ChromePdfRenderer();
            var pdf = renderer.RenderHtmlAsPdf("<h1>Hello, IronPDF!</h1><p>This is a generated PDF document.</p>");
            // Save the PDF to a byte array
            var pdfBytes = pdf.BinaryData;
            // Return the PDF file as a download
            return File(pdfBytes, "application/pdf", "example.pdf");
        }()
}

IRON VB CONVERTER ERROR developers@ironsoftware.com

The first thing we do in the PdfController code is import the required namespaces, which are Microsoft.AspNetCore.Mvc for ASP.NET Core MVC functionality and IronPDF for PDF generation. Because it derives from Controller, the PdfController class is an MVC controller. The GeneratePdf method in this class is defined to manage the creation of PDFs.

To convert HTML material into a PDF, this function creates an instance of IronPDF's ChromePdfRenderer(). A basic HTML string can be transformed into a PDF document using the RenderHtmlAsPdf function. The BinaryData attribute is then used to save this PDF to a byte array. Lastly, the PDF file is returned as a downloadable response using the File method, along with the requested filename (example.pdf) and the correct MIME type (application/pdf). The program can now dynamically create and serve PDF documents, based on HTML content thanks to this integration.

Route to Generate PDF

Make sure that the PDF generation routing is included in your Startup.cs file.

public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
    if (env.IsDevelopment())
    {
        app.UseDeveloperExceptionPage();
    }
    else
    {
        app.UseExceptionHandler("/Home/Error");
        app.UseHsts();
    }
    app.UseHttpsRedirection();
    app.UseStaticFiles();
    app.UseRouting();
    app.UseAuthorization();
    app.UseEndpoints(endpoints =>
    {
        endpoints.MapControllerRoute(
            name: "default",
            pattern: "{controller=Home}/{action=Index}/{id?}");
        endpoints.MapControllerRoute(
            name: "pdf",
            pattern: "pdf",
            defaults: new { controller = "Pdf", action = "GeneratePdf" });
    });
}
