Decode streams into strings The Right Way(tm)

# Decode streams into strings The Right Way(tm) ```javascript var fs = require('fs') var zlib = require('zlib') var strs = require('stringstream') var utf8Stream = fs.createReadStream('massiveLogFile.gz') .pipe(zlib.createGunzip()) .pipe(strs('utf8')) ``` No need to deal with `setEncoding()` weirdness, just compose streams like they were supposed to be! Handles input and output encoding: ```javascript // Stream from utf8 to hex to base64... Why not, ay. var hex64Stream = fs.createReadStream('myFile') .pipe(strs('utf8', 'hex')) .pipe(strs('hex', 'base64')) ``` Also deals with `base64` output correctly by aligning each emitted data chunk so that there are no dangling `=` characters: ```javascript var stream = fs.createReadStream('myFile').pipe(strs('base64')) var base64Str = '' stream.on('data', function(data) { base64Str += data }) stream.on('end', function() { console.log('My base64 encoded file is: ' + base64Str) // Wouldn't work with setEncoding() console.log('Original file is: ' + new Buffer(base64Str, 'base64')) }) ```
