# minizlib
|
|
|
|
A fast zlib stream built on [minipass](http://npm.im/minipass) and
|
|
Node.js's zlib binding.
|
|
|
|
This module was created to serve the needs of
|
|
[node-tar](http://npm.im/tar) and
|
|
[minipass-fetch](http://npm.im/minipass-fetch).
|
|
|
|
Brotli is supported in versions of node with a Brotli binding.
|
|
|
|
## How does this differ from the streams in `require('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](http://npm.im/minipass) for more on the differences between
|
|
Node.js core streams and Minipass streams, and the convenience methods
|
|
provided by that class.
|
|
|
|
## Classes
|
|
|
|
- Deflate
|
|
- Inflate
|
|
- Gzip
|
|
- Gunzip
|
|
- DeflateRaw
|
|
- InflateRaw
|
|
- Unzip
|
|
- BrotliCompress (Node v10 and higher)
|
|
- BrotliDecompress (Node v10 and higher)
|
|
|
|
## USAGE
|
|
|
|
```js
|
|
const zlib = require('minizlib')
|
|
const input = sourceOfCompressedData()
|
|
const decode = new zlib.BrotliDecompress()
|
|
const output = whereToWriteTheDecodedData()
|
|
input.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'.
