bspatch
Warning
This project is NOT an exact implementation that complies with the bsdiff4 format used in Colin Percival's bsdiff/bspatch binary.
Colin Percival (and many others) uses bzip2 as the compression algorithm, however it is too slow and I can't find a decent JS implementation that satisfies the tradeoff between binary size & speed. Thus, in this particular implementation gzip (inflate) is used instead.
Usage
bspatch(
old: Uint8Array,
patch: Uint8Array
): Promise<Uint8Array>Deadly simple. Just pass in the old file and the patch file, and you'll get the new file.
