It's just extra fields to parse.įor further improvement we could actually verify the checksums. This should illustrate the difference between the gzip and deflate-raw types. utils.js export function bufferToStream ( arrayBuffer ) Įnter fullscreen mode Exit fullscreen mode I'm also adding a few helper functions for reading different data types out of a DataView and being able to download arrays and blobs for verification. For this I've created some helpers to turn a stream into a blob and ArrayBuffers into streams. Streams aren't the easiest thing to work with especially if we're looking at whole files and ArrayBuffers. While the spec technically allows for other algorithms only DEFLATE ever seems to be used.įor more indepth I suggest looking at this post: Zips can take multiple files, put them together and then compress them using DEFLATE. "Zip" is a file format and what we are most interested in here. Web devs might also have noticed the Accept-Encoding: deflate value. gz.ĭEFLATE is the algorithm itself which combines huffman encoding and LZ77. "Gzip" can also be seen as a file format containing a gzip stream and usually uses the file-extension. "zlib" also refers to a C library which is one of the most popular implementations of DEFLATE from which the zlib data format descends from. "Gzip" and "Zlib" are both pieces of data with some headers and a checksum which represent compressed data. You'll likely see these terms used interchangeably, and this makes sense because they all refer to a piece of data that has been compressed with the DEFLATE algorithm. However we need to do a little bit of work to deal with the file format. So why couldn't devs have access to that? Well, more recently as of making this post this is possible in some environments using CompressionStreams and DecompressionStreams. This is used to decompress responses from the server with the header type Accept-Encoding. This was traditionally perplexing because the browser already needs to support the DEFLATE algorithm which is used by zip. There are certainly good libraries out there but as good front-end engineers we want to minimize our dependencies and the amount of code we ship. They are just zip archives! However, zip has traditionally been a bit hard to work with when in the browser. Try changing the extension to "zip" and see what happens when you open it. A classic example is Microsoft offices files. In fact you might even have formats that you didn't even know were zips. You've probably gotten them as downloads and other things to pack multiple files together. Don’t forget to give us feedback.Zips are a pretty common and ubiquitous format for compression.
