Usage

CRC32Stream

Inherits Transform Stream options and methods.

import { CRC32Stream } from "crc32-stream";

const source = fs.createReadStream("file.txt");
const 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();

DeflateCRC32Stream

Inherits zlib.DeflateRaw options and methods.

import { DeflateCRC32Stream } from "crc32-stream";

const source = fs.createReadStream("file.txt");
const checksum = new DeflateCRC32Stream();

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();

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)
