How to dowload huge files
My ReactJS app hits a Rest backend (I'm using Axios). I wish to hit some endpoint that returns a huge CSV report generated on the fly, in streaming mode. I'm using the standard recipe of doing my GET with Axios ( responseType: 'blob') and then using js-file-download

It's never been a better time to switch to Firefox
This! It is frustrating that web apps like draw.io can't save to file directly using Firefox. It gets old having to save a new file every time you make a change.
Beyond that, the File System API would also allow for streamed downloads directly from the web-app. This would allow for web-apps to generate large download files without having to store a copy on a database (external server or IndexedDB), which is a privacy improvement. The only way to do this now is by using convoluted techniques to essentially do a MITM to a fake endpoint [1].

UnCloud project: WebRTC chat, file transfer, and remote observation
Yuck, that sounds annoying. I'm on Linux and generally use Firefox, so I haven't run into that yet. I'm using https://github.com/jimmywarting/StreamSaver.js for saving data to disk, and it seems that a similar issue may be present for that project as well.

How can I create a dynamic file and then have user download it on a web app?
If it's larger, it's complicated... https://github.com/jimmywarting/StreamSaver.js generally works, but is not 100% reliable. https://github.com/jimmywarting/native-file-system-adapter is supposed to be like a newer version of it, but I struggled to get it working. You can also use https://web.dev/file-system-access/ but it's only supported in Chrome.

Help beta test a new feature - import/export leagues with no size limit
The hacky new way. There is a library which lets other browsers stream data to a file. Problem is, it's a bit unreliable. In my testing, I found it sometimes doesn't work in Firefox (reload usually fixes it) and it didn't work at all in mobile Chrome (not sure why yet).

Speer - a peer to peer communication app
Thank you for the kind words! Firefox is not fully supported, because of two things: - no support for WritableStream (used for downloading the files). Read more here - not supporting system audio capture at all Non of this is breaking though, and file downloading still works, but it might be a little slower.
