js-payload-compress

Use this to compress your 4k/8k/64k javascript intro. Compresses an input javascript with zopfli deflate. Writes a html output file containing a minimal unpack script in the onload attribute of a svg element that uses a DecompressionStream to decompress and eval the input javascript.
