I'm not sure what this would be called to know what to search for, if this is a duplicate please link me :)

Is it possible in JavaScript in a browser, to load an external file (this bit is easy), but given that the external file could be rather large (say 50MB) show a progress indicator of the loading of that file?

i.e I, knowing the serverside size of the file, not knowing the gzip size, I want to say X% of file loaded.

I've not tried anything, I can't find anything to work from let alone find something that suggests its possible.

Problem: Trying to load up a 50MB JavaScript library on demand but show the progress of the loading.

• javascript
• progress-bar
• dynamic-loading

• 50MB is huge! Is there any way to split this up into multiple files? Or reduce the size somehow? – Cameron Tinker Commented Apr 8, 2014 at 15:29
• 1 @CameronTinker - bgrins.github.io/videoconverter.js this is the library. I want to do pre-upload video file checking :) – Phill Commented Apr 8, 2014 at 16:01
• That's impressive! I will have to research this some more! I see on their website, they have a loading image indicating that the library is loading. – Cameron Tinker Commented Apr 8, 2014 at 16:06

Use XMLHttpRequest to load the script and monitor its progress. When it's done, eval() it.
