Replace one string with another string in a Node.js Stream. Only supports straight string replacement, no regexs. Handles replacing strings that span multiple chunks in the stream correctly.
npm install --save string-replace-stream
;var all = ;fs;
Buffers are converted to strings before search and replace is performed. You can specify an encoding (it defaults to utf8):
There are a couple of other similar libraries on NPM already:
replacestream: More fully featured, supports regular expressions. Can be a lot slower depending on the input (in my testing it does particulary badly with large streams in which the search string only seldom appears)
stream-replace: Much faster (about 5 times in my testing) but doesn't always give the right answer. Can't handle a search string that spans 3 or more chunks.
