Big File Support about genoverse

Just to point out, there's back-end code for all three of these in Biodalliance. We're currently trying to make this kind of back-end code more modular and easier to reuse in other projects. We could certainly split it out into another repository if that makes it easier to share with Genoverse.

I think this is a great idea. I will raise an issue with Dalliance
enquiring how likely this is

I would love to contribute to this port for big file formats 👍

I am happy to review pull requests

As a first step I have cloned the dalliance repo , trying to understand the js parser code. I hope I can produce something useful for this repo.

[sourabh2k15]

Just a thought : Can we compile the libBigWig C parser into JS using emscripten and use it to parse bigwig files on client side followed by our custom rendering logic that would display the data onto canvas ?

[andrewyatz]

I haven't had any experience of emscripten. I know that libBigWig uses libcurl and zlib. I don't know how these work with emscripten.

[sourabh2k15]

Even I haven't had much experience with emscripten other than knowing the fact that it is powerful and can convert any LLVM code to javascript which can be then executed in node environments or in the browser. I have tried it by converting simple C and C++ code to JS.

The examples of what have been already been ported over to javascript with emscripten, gave me confidence to think in this direction ( entire ffmpeg library ported to ffmpeg.js 🥇 !! ) :

This guy has tried porting htslib to javascript through emscripten : https://github.com/cmdcolin/htslib_emscripten. Will try to follow his work and compile htslib to js modules 😄
htslib also uses zlib. Let me know if this is worth a try and your thoughts on this.

[andrewyatz]

I think it's worth a try though I'm not sure totally sure of the pros/cons of doing this.
