fflate | High performance compression in an 8kB package | Compression library

I have a service that sends me data through WebSocket however the data is gzipped. when I try to ungziped the Blob data I have a problem. I used packages fflate gzip-js pako and zlib all with different error but the funny thing when I write the code for node js Server with package node-gzip which underhood used the zlib package mention above everything is fine and the data will be ungzped.

Client.js (Problem is unGzip data)

I'm working on a JavaScript compression library. I've already created a relatively fast DEFLATE compressor and decompressor, but they require the data to be fully loaded in memory prior to use. I don't think adding streaming support for the compression should be too difficult; I can just compress whatever data is available into a set of full blocks, append the result to the output stream, and avoid setting the BFINAL marker until the final chunk is passed. However, an issue arises with decompression streams.

Since my code currently needs to read a full chunk to generate an output and does not preserve state, the best I can do is guess how long a chunk is and hope that I reach the end, because if I don't, I've wasted multiple CPU cycles reading the headers, Huffman codes, and length/literal and distance codes of the unfinished block, and I'll have to do that all over again. This seems to be an awful way of solving the problem, and I'm wondering if there's any other way to do this that doesn't involve rewriting my code to preserve state.
