Efficient streaming find and replace. Buffer based and boundary aware.
npm install stream-buffer-replace
- never converts Buffers to strings
- only supports exact matching not patterns / regexs
- finds matches that span chunk boundaries
- finds matches that are bigger than a single chunk
example using strings...
var fs = require('fs');
var replace = require('stream-buffer-replace');
fs.writeFileSync('example.txt', "hello world");
var stream = fs.createReadStream('example.txt');
stream.pipe( replace('hello', 'goodbye') ).pipe(process.stdout);
=> goodbye world
example using buffers...
var fs = require('fs');
var replace = require('stream-buffer-replace');
fs.writeFileSync('example.txt', "hello world");
var stream = fs.createReadStream('example.txt');
var replacer = replace(new buffer('hello'), new Buffer('goodbye'));
stream.pipe( replacer ).pipe(process.stdout);
=> goodbye world
Are written with Mocha and can be run with...
