Package Exports

crc32-stream

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (crc32-stream) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

crc32-stream v0.1.2

crc32-stream is a streaming CRC32 checksumer. It uses buffer-crc32 behind the scenes to reliably handle binary data and fancy character sets. Data is passed through untouched.

Install

npm install crc32-stream --save

You can also use npm install https://github.com/ctalkington/node-crc32-stream/archive/master.tar.gz to test upcoming versions.

Usage

var CRC32Stream = require('crc32-stream');

var source = fs.createReadStream('file.txt');
var checksum = new CRC32Stream();

checksum.on('end', function(err) {
  // do something with checksum.digest() here
});

// either pipe it
source.pipe(checksum);

// or write it
checksum.write('string');
checksum.end();
