Convert a classic-stream, or a new-stream into a pull-stream
var toPull = require('stream-to-pull-stream')
var pull = require('pull-stream')
pull(
toPull.source(fs.createReadStream(__filename)),
pull.map(function (e) { return e.toString().toUpperCase() }),
toPull.sink(process.stdout, function (err) {
if(err) throw err
console.log('done')
})
)if the node steam is a duplex (i.e. net, ws) then use toPull.duplex(stream, cb?)
duplex takes an optional callback in the same way that sink does.
