Using PDFium in cross platform apps

[Dimuthu Upeksha]

We are planning to evaluate integrating pdfium into our pdf annotation application. We plan to use react native for IOS and Android, and electron js for native apps. Is there any previous integration of PDFium for these platforms? If not, what is the recommended way to bundle PDFium?

I'm not familiar with the frameworks you mentioned, but Chromium uses
PDFium on Windows/Mac/Linux/ChromeOS. There are apps using PDFium on
Android. While PDFium is not officially supported on iOS, there exists
projects to patch PDFium and make it work.

Hi Lei,

Thanks for the context. Apologies for the open-ended question. Let me narrow it down. All the platforms I mentioned above use some form of JavaScript runtime. Is there any previous work on integrating PDFium with Javascript? For example, someone might have a use case to have a PDF viewer in their React web application and PDFium might be a good candidate if it can be integrated into React's javascript environment.

Thanks

Dimuthu

Yes we integrate Pdfium into a commercial Javascript software component.

We use gRPC but presumably you could interop directly from Javascript to C++ or perhaps use WASM
