node.js - the best way to replace content in buffer

Question

I am reading a file to buffer like:

var myfile = fs.readFileSync(myfile.txt);

What is the proper way to replace some string to another in myfile buffer? I would like to keep it as buffer, because it is faster than to keep it as string.

Answer 1

The package buffer-replace https://www.npmjs.com/package/buffer-replace replaces content in a buffer like the function replace for String.
