I'm new here and I'm doing my first app with react-native and expo and I encountered a problem with a PDF response from an API.
The objective here is to be able to call the API and receive an application/pdf response and download it whenever you press a button. All this works smoothly but I can't manage any way to interpret the pdf response and do something out of it.
Some ways I've tried :
- interpret it in a pdfViewer
- Download it with Expo FileSystem
- Open it in a new window or a webView
- use rn-fetch-blob (can't because of expo)
- use Print.printToFileAsync
- ...
Most problems come from the fact that I need an uri from the file to do anything with it but it looks like I can't create an url from a Blob. I get this error when I try to createObjectURL
Error: Cannot create URL for blob!
// Working API Call
response = await axios.get(apiUri.DownloadDocument +id) this.props.id);
// Blob creation
const file = new Blob(
[response.data],
{type: 'application/pdf'});
// This line throws an error
const fileURL = URL.createObjectURL(file);
WebBrowser.openBrowserAsync(fileURL);
If I call the API with POSTMAN, he can't preview the response but I can download it and it's the pdf file with no problem.

I might be doing it totally the wrong way since i'm new to this. Thanks for your time and expertise. Here is the output of the response from the API I get with console.log(response.data)
