Class ZipWriterStream

Represents an instance used to create a zipped stream.

Example

This example creates a zipped file called numbers.txt.zip containing the numbers 0 - 1000 each on their own line.

const readable = ReadableStream.from((function* () {
  for (let i = 0; i < 1000; ++i)
    yield i + '\n'
})())

readable
  .pipeThrough(new ZipWriterStream().transform('numbers.txt'))
  .pipeTo((await Deno.create('numbers.txt.zip')).writable)

Example

This example creates a zipped file called Archive.zip containing two files called numbers.txt and letters.txt

const readable1 = ReadableStream.from((function* () {
  for (let i = 0; i < 1000; ++i)
    yield i + '\n'
})())
const readable2 = ReadableStream.from((function* () {
  const letters = 'abcdefghijklmnopqrstuvwxyz'.split('')
  while (letters.length)
    yield letters.shift() + '\n'
})())

const zipper = new ZipWriterStream()
zipper.readable.pipeTo((await Deno.create('Archive.zip')).writable)
readable1.pipeTo(zipper.writable('numbers.txt'))
readable2.pipeTo(zipper.writable('letters.txt'))
zipper.close()
