ASP.NET Core Blazor: Building PDF Powerhouses

ASP.NET Core Blazor empowers developers to create interactive web applications using C# instead of JavaScript. One common requirement for many web applications is generating and manipulating PDF documents. Blazor, with its server-side and client-side hosting models, offers several approaches to effectively handle PDF generation and interaction. These approaches vary in complexity and depend on the application's specific needs, from simple PDF viewing to complex document generation with dynamic data.

What is Blazor?

Blazor, a web framework developed by Microsoft, allows you to build interactive client-side web UI with C# instead of JavaScript. Blazor supports two main hosting models: Blazor Server, where the application executes on the server, and Blazor WebAssembly, where the application runs directly in the user's browser. This flexibility provides options to optimize performance and user experience. Learn more about the Blazor web framework on Wikipedia. weaver hints today

Generating PDFs in Blazor

Several libraries and methods can be used to generate PDFs within a Blazor application. Some common approaches include:

Server-Side PDF Generation

In Blazor Server applications, you can leverage server-side libraries like iTextSharp (although iText 7 is the recommended version) or PDFsharp to generate PDF documents. This approach involves creating the PDF document on the server and then sending it to the client for download or display. It benefits from the full power of the server's processing capabilities and access to resources.

Client-Side PDF Generation with Blazor WebAssembly

For Blazor WebAssembly applications, you can use client-side JavaScript interop or WASM-compatible .NET libraries to generate PDFs directly in the browser. JavaScript libraries like jsPDF or PDFMake can be called from your Blazor code using JavaScript interop. WASM compatible . weaver today hintNET libraries, though fewer in number, can also be utilized.

Displaying PDFs in Blazor

Whether the PDF is generated server-side or client-side, displaying it within a Blazor application requires a suitable viewer. Common approaches include:

Using an Iframe
