1896509 - Implement `bytes()` method on Blob for reading bytes into a Uint8Array

Status: RESOLVED FIXED

(Core :: DOM: File, enhancement)

Description

[bakkot]

Steps to reproduce:

See https://github.com/w3c/FileAPI/pull/197. This is like the existing arrayBuffer() method (implemented in https://bugzilla.mozilla.org/show_bug.cgi?id=1557121), but gives you a Uint8Array instead.

Tests at https://github.com/web-platform-tests/wpt/pull/46232

Does this really "depend on" bug 1896475?

Comment 2

[Kagami Rosylight [:saschanaz] (they/them)]

I guess yes given the dependency on BodyUtils. I guess this then would be as easy as adding a method with ConsumeBody(ConsumeType::Bytes)?

[Tom S. (please needinfo tschuster)]

Yes exactly, it depends on BodyConsumer. Maybe 5 lines of code. However I am currently waiting for the WPT merge to happen.

Kagami can we signal support on the PR?
