Simple random stream: This example shows how to use a custom stream to generate random strings, enqueue them as chunks, and then read them back out again.

Grayscale a PNG: This example shows how a ReadableStream of a PNG can be turned into grayscale.

Simple stream pump: This example shows how to consume a ReadableStream and pass its data to another.

We have created a directory of examples to go along with the Streams API documentation - see mdn/dom-examples/streams. You can also write data to streams using WritableStream. More complicated uses involve creating your own stream using the ReadableStream() constructor, for example to process data inside a service worker. For example, the response body returned by a successful fetch request can be exposed as a ReadableStream, and you can then read it using a reader created with ReadableStream.getReader(), cancel it with ReadableStream.cancel(), etc. The basic usage of Streams hinges around making responses available as streams. There are more advantages too - you can detect when streams start or end, chain streams together, handle errors and cancel streams as required, and react to the speed the stream is being read at.

With Streams being available to JavaScript, this all changes - you can now start processing raw data with JavaScript bit by bit as soon as it is available on the client-side, without needing to generate a buffer, string, or blob.

Previously, if we wanted to process a resource of some kind (be it a video, or a text file, etc.), we'd have to download the entire file, wait for it to be deserialized into a suitable format, then process the whole lot after it is fully received. This is something browsers do anyway when receiving assets to be shown on webpages - videos buffer and more is gradually available to play, and sometimes you'll see images display gradually as more is loaded.Д«ut this has never been available to JavaScript before. Streaming involves breaking a resource that you want to receive over a network down into small chunks, then processing it bit by bit.
