React Native:
- `fetch` does not have streaming support
- No `TextDecoder`
- No `Event`, `EventTarget`, `MessageEvent`
- `URLSearchParams` only has `append` method
Wish it had a similar push for supporting web APIs as Node.js did recently. Making cross-env libraries that support RN is not easy.

I would never say that I _miss_ pandemic times, but I did spend 3-4 weeks making a scenario based on A Song of Ice and Fire for a 30 year old isometric 2D game, with zero regrets or shame 🤔

Sometimes I wish there was a way to message people on GitHub.
Someone leaves an issue or a comment on one of my repos and I'm curious how they are using it, but don't want the interaction to be in public (noise/irrelevant to the thread).
Of course, I understand what a slippery slope that could be.

Introducing Standard Schema! It’s a specification for a standard interface to be implemented by TypeScript schema libraries. The goal is to make it easier for frameworks and tools to accept user-defined schemas, without writing separate adapters for different libraries.

Is there a way to test a module in React Native's JavaScript environment, without running a full emulator? Does the jest environment catch things like the broken URL and Intl implementation etc?
This is a for a generic JS module that should _preferably_ work in React Native.

Big thanks to libvips team (@jcupitt.bsky.social @lovell.info @kleisauke.nl) for creating a lightning-fast, incredibly reliable image processing library.
Some of the nicest open-source maintainers you'll ever meet - polite, helpful and responsive.
Happy that @sanity.io sponsored them with $4000 ✨

This release is anything but boring.
Mapping "free-form" content into the structured schemas defined in Sanity? Really cool. Can't wait to continue building on this and get closer to realizing the full "content operating system" vision we have in mind - you're going to love it.

While we're on the subject of open-source sustainability; giving thanks to open-source maintainers (beyond $$ support) is not something I do often enough. Going forward, I am going to start posting more about the awesome projects, apps, modules and tools that I use.

Proud to be working at a company that recognizes the value of giving back to open-source maintainers and to push towards a more sustainable open-source culture.
Open source software is crucial to the success of Sanity, so it makes sense to give back to great projects that we and our community use every day.
That's why we joined the @opensourcepledge.com with a $112k donation to great projects and maintainers. 🫶

Is there a way to track upload progress when using `fetch()` yet? Should be possible using a custom read stream, but unsure if backpressure will work correctly or if you would end up with "read"-progress instead of "send"-progress
