This PR makes usage of
Bufferoptional. If input type isBuffer, zip header searching is conducted with much fasterBuffer.indexOf, otherwise single-byteUint8Array.indexOfis used, which results in many false positives that must be discarded. Thus usingBuffertype as input is still the best option in terms of speed and memory usage.Tested on the same 169MB .zip file as before, resulting in 49ms with
Bufferand 465ms withoutBuffer.
