minizlib
A fast zlib stream built on minipass and Node.js's zlib binding.
This module was created to serve the needs of node-tar and minipass-fetch.
Brotli is supported in versions of node with a Brotli binding.
How does this differ from the streams in 'node:zlib'?
First, there are no convenience methods to compress or decompress a
buffer. If you want those, use the built-in zlib module. This is
only streams. That being said, Minipass streams to make it fairly easy to
use as one-liners: new zlib.Deflate().end(data).read() will return the
deflate compressed result.
This module compresses and decompresses the data as fast as you feed it in. It is synchronous, and runs on the main process thread. Zlib and Brotli operations can be high CPU, but they're very fast, and doing it this way means much less bookkeeping and artificial deferral.
Node's built in zlib streams are built on top of stream.Transform.
They do the maximally safe thing with respect to consistent
asynchrony, buffering, and backpressure.
See Minipass for more on the differences between Node.js core streams and Minipass streams, and the convenience methods provided by that class.

USAGE
1import { BrotliDecompress } from 'minizlib' 2// or: const BrotliDecompress = require('minizlib') 3 4const input = sourceOfCompressedData() 5const decode = new BrotliDecompress() 6const output = whereToWriteTheDecodedData() 7input.pipe(decode).pipe(output)
REPRODUCIBLE BUILDS
To create reproducible gzip compressed files across different operating
systems, set portable: true in the options. This causes minizlib to set
the OS indicator in byte 9 of the extended gzip header to 0xFF for
'unknown'.
