unbzip2-stream
|
|
===
|
|
streaming bzip2 decompressor in pure JS for Node and browserify.
|
|
|
|
Buffers
|
|
---
|
|
When browserified, the stream emits instances of [feross/buffer](https://github.com/feross/buffer) instead of raw Uint8Arrays to have a consistant API across browsers and Node.
|
|
|
|
Usage
|
|
---
|
|
``` js
|
|
var bz2 = require('unbzip2-stream');
|
|
var fs = require('fs');
|
|
|
|
// decompress test.bz2 and output the result
|
|
fs.createReadStream('./test.bz2').pipe(bz2()).pipe(process.stdout);
|
|
```
|
|
|
|
Also see [test/browser/download.js](https://github.com/regular/unbzip2-stream/blob/master/test/browser/download.js) for an example of decompressing a file while downloading.
|
|
|
|
Or, using a <script> tag
|
|
---
|
|
|
|
```
|
|
<script src="https://npm-cdn.info/unbzip2-stream/dist/unbzip2-stream.min.js"></script>
|
|
<script>
|
|
var myStream = window.unbzip2Stream();
|
|
// now pipe stuff through it (see above)
|
|
</script>
|
|
```
|
|
|
|
Tests
|
|
---
|
|
To run tests in Node:
|
|
|
|
npm run test
|
|
|
|
To run tests in PhantomJS
|
|
|
|
npm run browser-test
|
|
|
|
Additional Tests
|
|
----------------
|
|
There are two more tests that specifically test decompression of a very large file. Because I don't want to include large binary files in this repository, the files are created by running an npm script.
|
|
|
|
npm run prepare-long-test
|
|
|
|
You can now
|
|
|
|
npm run long-test
|
|
|
|
And to run a test in chrome that downloads and decompresses a large binary file
|
|
|
|
npm run download-test
|
|
|
|
Open the browser's console to see the output.
