Pipes supercharge today! 🚀

Features

• Delayed piping. You can fill dependent streams at any time during the origin process lifecycle (even when finished) without losing data. #914

const result = $`echo 1; sleep 1; echo 2; sleep 1; echo 3`
const piped1 = result.pipe`cat`
let piped2
setTimeout(() => {
piped2 = result.pipecat
}, 1500)
await piped1
assert.equal((await piped1).toString(), '1\n2\n3\n')
assert.equal((await piped2).toString(), '1\n2\n3\n')

• Promisified streams. #921 #922 #923 #928

const file = tempfile()
const fileStream = fs.createWriteStream(file)
const p = $`echo "hello"`
  .pipe(
    new Transform({
      transform(chunk, encoding, callback) {
        callback(null, String(chunk).toUpperCase())
      },
    })
  )
  .pipe(fileStream)
p instanceof WriteStream             // true
await p === fileStream               // true
(await fs.readFile(file)).toString() // 'HELLO\n'
