A transform-stream for Node and browsers that efficeintly replaces sequences of bytes in a binary stream. Can be restricted to replace first n occurrences only.
var ReplaceStream = require('binary-stream-replace');
// replace first 10 occurrences of byte sequence `fe fe` with
// `00 00 01`
var rs = ReplaceStream(
new Buffer([0xfe, 0xfe]),
new Buffer([0x00, 0x00, 0x01]),
{ maxOccurrences: 10 }
);
process.stdin.pipe(rs).pipe(process.stdout);
