Data Sources and Sinks

The Arrow JavaScript API is designed to make it easy to work with data sources both in the browser and in Node.js.

Streams​

Both Node and DOM/WhatWG Streams can be used directly as input sources by the Arrow JS API.

Fetch Responses​

Fetch responses (Promises) can be used where a data source is expected.

ArrayBuffers​

Most data sources accept Uint8Arrays.

AsyncIterators​

Async iterators are the most general way to abstract "streaming" data sources and data sinks and are consistently accepted (and in many cased returned) by the Arrow JS API.
