Create and Configure WebGrease

To use WebGrease in a .NET Core application, install the necessary packages, configure the build process, and set up optimization tasks. The following steps will help you establish and set up WebGrease in a .NET Core application:

Create a .NET Core Project

First, create a new .NET Core web application. You can use the .NET CLI for this purpose.

dotnet new web -n WebGreaseApp
cd WebGreaseApp

dotnet new web -n WebGreaseApp
cd WebGreaseApp

Add Required Packages

Although there isn't a direct .NET Core package for WebGrease, you can achieve similar functionality with other programs like BundlerMinifier. Add this package to your project.

dotnet add package BundlerMinifier.Core

dotnet add package BundlerMinifier.Core

Configure Bundling and Minification

Create a bundleconfig.json file in your project root to provide the bundling and minification settings for your CSS and JavaScript files. Here is an example configuration.

[
  {
    "outputFileName": "wwwroot/css/site.min.css",
    "inputFiles": [
      "wwwroot/css/site.css"
    ],
    "minify": {
      "enabled": true,
      "renameLocals": true
    }
  },
  {
    "outputFileName": "wwwroot/js/site.min.js",
    "inputFiles": [
      "wwwroot/js/site.js"
    ],
    "minify": {
      "enabled": true
    }
  }
]

[
  {
    "outputFileName": "wwwroot/css/site.min.css",
    "inputFiles": [
      "wwwroot/css/site.css"
    ],
    "minify": {
      "enabled": true,
      "renameLocals": true
    }
  },
  {
    "outputFileName": "wwwroot/js/site.min.js",
    "inputFiles": [
      "wwwroot/js/site.js"
    ],
    "minify": {
      "enabled": true
    }
  }
]

Integrate with the Build Process

Add instructions to execute the bundling and minification operations during the build process in your project file (.csproj).

Add the following element inside the <Project> element in your .csproj file:

<Target Name="PrepublishScript" BeforeTargets="PrepareForPublish">
  <Exec Command="dotnet bundle" />
</Target>

<Target Name="PrepublishScript" BeforeTargets="PrepareForPublish">
  <Exec Command="dotnet bundle" />
</Target>

Install and Run BundlerMinifier

To use the BundlerMinifier tool, you must install the .NET utility. Execute the following command:

dotnet tool install -g BundlerMinifier.Core

dotnet tool install -g BundlerMinifier.Core

To bundle and minify your files, run:

dotnet bundle

dotnet bundle

Optimize Images

You can use ImageSharp or other .NET Core-compliant image optimization tools for image optimization.

Install ImageSharp

Install the SixLabors.ImageSharp package:

dotnet add package SixLabors.ImageSharp

dotnet add package SixLabors.ImageSharp

Here is an example of a code snippet for image optimization:

using SixLabors.ImageSharp;
using SixLabors.ImageSharp.Processing;
using System.IO;

public void OptimizeImage(string inputPath, string outputPath)
{
    // Load the image
    using (var image = Image.Load(inputPath))
    {
        // Resize and optimize the image
        image.Mutate(x => x.Resize(new ResizeOptions
        {
            Mode = ResizeMode.Max,
            Size = new Size(800, 600)
        }));
        // Save the image in an optimized format
        image.Save(outputPath); // Automatic encoder selected based on file extension.
    }
}

using SixLabors.ImageSharp;
using SixLabors.ImageSharp.Processing;
using System.IO;

public void OptimizeImage(string inputPath, string outputPath)
{
    // Load the image
    using (var image = Image.Load(inputPath))
    {
        // Resize and optimize the image
        image.Mutate(x => x.Resize(new ResizeOptions
        {
            Mode = ResizeMode.Max,
            Size = new Size(800, 600)
        }));
        // Save the image in an optimized format
        image.Save(outputPath); // Automatic encoder selected based on file extension.
    }
}

Imports SixLabors.ImageSharp
Imports SixLabors.ImageSharp.Processing
Imports System.IO

Public Sub OptimizeImage(ByVal inputPath As String, ByVal outputPath As String)
	' Load the image
	Using image = System.Drawing.Image.Load(inputPath)
		' Resize and optimize the image
		image.Mutate(Function(x) x.Resize(New ResizeOptions With {
			.Mode = ResizeMode.Max,
			.Size = New Size(800, 600)
		}))
		' Save the image in an optimized format
		image.Save(outputPath) ' Automatic encoder selected based on file extension.
	End Using
End Sub

Imports SixLabors.ImageSharp
Imports SixLabors.ImageSharp.Processing
Imports System.IO

Public Sub OptimizeImage(ByVal inputPath As String, ByVal outputPath As String)
	' Load the image
	Using image = System.Drawing.Image.Load(inputPath)
		' Resize and optimize the image
		image.Mutate(Function(x) x.Resize(New ResizeOptions With {
			.Mode = ResizeMode.Max,
			.Size = New Size(800, 600)
		}))
		' Save the image in an optimized format
		image.Save(outputPath) ' Automatic encoder selected based on file extension.
	End Using
End Sub

Run your application to ensure bundling and minification are operating as intended. Open your application in the browser, then verify that the JavaScript and CSS files are minified.

By following these steps, you can set up and configure WebGrease-like optimization for a .NET Core application using tools compatible with the current .NET environment.

Configure Bundling and Minification

Ensure that the bundleconfig.json config file is in place to provide the bundling and minification settings again as needed:

[
  {
    "outputFileName": "wwwroot/css/site.min.css",
    "inputFiles": [
      "wwwroot/css/site.css"
    ],
    "minify": {
      "enabled": true,
      "renameLocals": true
    }
  },
  {
    "outputFileName": "wwwroot/js/site.min.js",
    "inputFiles": [
      "wwwroot/js/site.js"
    ],
    "minify": {
      "enabled": true
    }
  }
]

[
  {
    "outputFileName": "wwwroot/css/site.min.css",
    "inputFiles": [
      "wwwroot/css/site.css"
    ],
    "minify": {
      "enabled": true,

    }
  },
  {
    "outputFileName": "wwwroot/js/site.min.js",
    "inputFiles": [
      "wwwroot/js/site.js"
    ],
    "minify": {
      "enabled": true
    }
  }
]

Connect to the Building Process

Ensure that your .csproj file contains instructions for executing the minification and bundling operations during the build process. Add the following Target within the <Project> element:

<Target Name="PrepublishScript" BeforeTargets="PrepareForPublish">
  <Exec Command="dotnet bundle" />
</Target>

<Target Name="PrepublishScript" BeforeTargets="PrepareForPublish">
  <Exec Command="dotnet bundle" />
</Target>

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");
        }
    }
}

Imports Microsoft.AspNetCore.Mvc
Imports IronPdf

Namespace WebGreaseIronPdfApp.Controllers
    Public Class PdfController
        Inherits Controller

        Public Function GeneratePdf() As IActionResult
            ' Create a PDF from a simple HTML string
            Dim renderer = New ChromePdfRenderer()
            Dim pdf = renderer.RenderHtmlAsPdf("<h1>Hello, IronPDF!</h1><p>This is a generated PDF document.</p>")

            ' Save the PDF to a byte array
            Dim pdfBytes = pdf.BinaryData

            ' Return the PDF file as a download
            Return File(pdfBytes, "application/pdf", "example.pdf")
        End Function
    End Class
End Namespace

Imports Microsoft.AspNetCore.Mvc
Imports IronPdf

Namespace WebGreaseIronPdfApp.Controllers
    Public Class PdfController
        Inherits Controller

        Public Function GeneratePdf() As IActionResult
            ' Create a PDF from a simple HTML string
            Dim renderer = New ChromePdfRenderer()
            Dim pdf = renderer.RenderHtmlAsPdf("<h1>Hello, IronPDF!</h1><p>This is a generated PDF document.</p>")

            ' Save the PDF to a byte array
            Dim pdfBytes = pdf.BinaryData

            ' Return the PDF file as a download
            Return File(pdfBytes, "application/pdf", "example.pdf")
        End Function
    End Class
End Namespace

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.

            pattern: "pdf",
            defaults:=New With {.controller = "Pdf", .action = "GeneratePdf"})
    End Sub)
End Sub

Public Sub Configure(app As IApplicationBuilder, env As IWebHostEnvironment)
    If env.IsDevelopment() Then
        app.UseDeveloperExceptionPage()
    Else
        app.UseExceptionHandler("/Home/Error")
        app.UseHsts()
    End If
    app.UseHttpsRedirection()
    app.UseStaticFiles()
    app.UseRouting()
    app.UseAuthorization()
    app.UseEndpoints(Sub(endpoints)
        endpoints.MapControllerRoute(
            name: "default",
            pattern: "{controller=Home}/{action=Index}/{id?}")
        endpoints.MapControllerRoute(
            name: "pdf",
            pattern: "pdf",
