switchstream
Change where data flows as it passes through the switchstream.
var Switchstream = require('switchstream')
var switchstream = Switchstream(function(data) {
// return the key of the stream you want to
// pipe this data to
if (data === 'a') return 'stream a'
if (data === 'b') return 'stream b'
})
from(['a', 'b', 'a', 'a', 'b']) // example data
.pipe(switchstream.between({
'stream-a': fs.createWriteStream('a.txt'),
'stream-b': fs.createWriteStream('b.txt')
}))
// result will be a.txt with the three a's and b.txt with the two b's
