CRC32 Stream
crc32-stream is a streaming CRC32 checksumer. It uses the crc module behind the scenes to reliably handle binary data and fancy character sets. Data is passed through untouched.
Install
1npm install crc32-stream --save
You can also use npm install https://github.com/archiverjs/node-crc32-stream/archive/master.tar.gz to test upcoming versions.
Usage
CRC32Stream
Inherits Transform Stream options and methods.
1import { CRC32Stream } from "crc32-stream"; 2 3const source = fs.createReadStream("file.txt"); 4const checksum = new CRC32Stream(); 5 6checksum.on("end", function (err) { 7 // do something with checksum.digest() here 8}); 9 10// either pipe it 11source.pipe(checksum); 12 13// or write it 14checksum.write("string"); 15checksum.end();
DeflateCRC32Stream
Inherits zlib.DeflateRaw options and methods.
1import { DeflateCRC32Stream } from "crc32-stream"; 2 3const source = fs.createReadStream("file.txt"); 4const checksum = new DeflateCRC32Stream(); 5 6checksum.on("end", function (err) { 7 // do something with checksum.digest() here 8}); 9 10// either pipe it 11source.pipe(checksum); 12 13// or write it 14checksum.write("string"); 15checksum.end();
Instance API
digest()
Returns the checksum digest in unsigned form.
hex()
Returns the hexadecimal representation of the checksum digest. (ie E81722F0)
size(compressed)
Returns the raw size/length of passed-through data.
If compressed is true, it returns compressed length instead. (DeflateCRC32Stream)
