Blazor Reports

Generate PDF reports using Blazor Components. Easily create a report server or generate reports from existing projects.

Requirements

• .NET 8.0 or later for report server
• .NET 6.0 or later for Blazor Components shared library
• Chrome, Chromium, or Edge browser for report generation

Basic usage for report server

1. Install the Blazor Reports NuGet package:

   dotnet add package BlazorReports

2. Configure Blazor Reports and map the component:

   var builder = WebApplication.CreateSlimBuilder(args);
   
   builder.Services.AddBlazorReports(); // Configure BlazorReports
   
   var app = builder.Build();
   
   app.MapBlazorReport<MyBlazorComponent>(); // Map Blazor Component
   app.MapBlazorReport<OtherBlazorComponent, MyDataDto>(); // Map Blazor Component and receive data
   
   app.Run();

3. Send HTTP POST request to the Blazor Reports endpoint:

   POST /MyBlazorComponent
   
   POST /OtherBlazorComponent
   Content-Type: application/json
   {
     "text": "Hello World!"
   }

4. Get back PDF Report.

Sample Blazor Components

// MyBlazorComponent: Basic component
<h3>Hello World!</h3>

@code {

}

// OtherBlazorComponent: Component that receives data
<h3>@Data?.Text</h3>

@code {
    [Parameter]
    public required MyDataDto Data { get; set; }
}

Advanced usage

Add Base styles

1. Configure base styles file in options for AddBlazorReports:

   var builder = WebApplication.CreateSlimBuilder(args);
   
   builder.Services.AddBlazorReports(options =>
   {
     options.BaseStylesPath = "wwwroot/styles/base.css";
   });
   
   var app = builder.Build();
   
   app.MapBlazorReport<MyBlazorComponent>();
   
   app.Run();

2. Configured components will now have the base styles applied.

Configure Tailwind CSS

1. Add 'tailwind.config.js' file to the root of your project:

   /** @type {import('tailwindcss').Config} */
   module.exports = {
   content: ['./**/*.{razor,html}'],
   theme: {
   extend: {},
   },
   plugins: [],
   }

2. Add 'tailwind.css' file:

   @tailwind base;
   @tailwind components;
   @tailwind utilities;

3. Use the following command to generate the base.css file:

   npx tailwindcss -i ./wwwroot/styles/tailwind/tailwind.css -o ./wwwroot/styles/base.css -m --watch

4. Configure BaseStyles in Program.cs:

   var builder = WebApplication.CreateSlimBuilder(args);
   
   builder.Services.AddBlazorReports(options =>
   {
     options.BaseStylesPath = "wwwroot/styles/base.css";
   });
   
   var app = builder.Build();
   
   app.MapBlazorReport<MyBlazorComponent>();
   
   app.Run();

Configure assets

1. Configure assets in Program.cs:

   var builder = WebApplication.CreateSlimBuilder(args);
   
   builder.Services.AddBlazorReports(options =>
   {
     options.AssetsPath = "wwwroot/assets";
   });
   
   var app = builder.Build();
   
   app.MapBlazorReport<MyBlazorComponent>();
   
   app.Run();

2. Add inheritance for BlazorReportsComponentBase:

   @inherits BlazorReports.Components.BlazorReportsBase
   
   <img src="@GlobalAssets.GetValueOrDefault("logo-salud.png")"/>
   
   @code {
   
   }

3. All files will be available as base64 strings in the 'GlobalAssets' dictionary.

OpenAPI, Swagger, Authentication, Authorization, Validation, etc.

Blazor reports utilizes Minimal APIs under the hood and can be configured as any other Minimal API project.

For example, to add OpenAPI and Swagger:

1. Add OpenAPI and Swagger NuGet packages.
2. Configure OpenAPI and Swagger:

   var builder = WebApplication.CreateSlimBuilder(args);
   
   builder.Services.AddBlazorReports();
   builder.Services.AddEndpointsApiExplorer();
   builder.Services.AddSwaggerGen();
   
   var app = builder.Build();
   
   app.UseSwagger();
   app.UseSwaggerUI();
   
   app.MapBlazorReport<MyComponent, MyComponentData>();
   app.MapBlazorReport<MyOtherComponent>();
   
   app.Run();

3. Open Swagger UI at '/swagger' endpoint.
4. You can see each report endpoint configured with expected data model.
