import { Duplex } from "https://deno.land/std@0.176.0/node/stream.ts";

A utility method for creating duplex streams.

  • Stream converts writable stream into writable Duplex and readable stream to Duplex.
  • Blob converts into readable Duplex.
  • string converts into readable Duplex.
  • ArrayBuffer converts into readable Duplex.
  • AsyncIterable converts into a readable Duplex. Cannot yield null.
  • AsyncGeneratorFunction converts into a readable/writable transform Duplex. Must take a source AsyncIterable as first parameter. Cannot yield null.
  • AsyncFunction converts into a writable Duplex. Must return either null or undefined
  • Object ({ writable, readable }) converts readable and writable into Stream and then combines them into Duplex where the Duplex will write to the writable and read from the readable.
  • Promise converts into readable Duplex. Value null is ignored.
