Specification

None

Summary

NativeIO is a storage API that resembles a very basic filesystem, with direct access to stored data through buffers and offsets. Our goal is to give developers flexibility by providing generic, simple, and performant primitives upon which they can build higher-level components. It's particularly well suited for Wasm-based libraries and applications that want to use custom storage algorithms to fine-tune execution speed and memory usage.

Motivation

A generic, performant and low-level storage API would enable web developers to create or port storage libraries that offer the right guarantees and interface for their application. Pushing the storage layer onto the client-side allows developers to rely on interfaces that are cross-platform and widens the possible APIs from the ones currently provided by the Web Platform to the ones that could be ported or created.

Risks



Interoperability and Compatibility

This new feature has some potential interoperability risks due to its nature as a novel and low-level API. Currently, there are no web features that expose such a generic interface and that focus on WebAssembly ports as one of it's main consumers.



Gecko: No signal

WebKit: No signal

Web developers: No signals


Will this feature be supported on all six Blink platforms (Windows, Mac, Linux, Chrome OS, Android, and Android WebView)?

Yes


Is this feature fully tested by web-platform-tests?

Yes
