Support for FileSystemWritableFileStream has been added! It's exciting to me because lack of Safari support was the #1 biggest pain point to using the Origin Private File System. (See my recent Ask HN for more details about the OPFS [0], but the short version is that it gives websites access to a private directory on your computer, that they can write to and read from later.) I haven't yet been able to verify that it works as expected, but if so, it's very exciting because it means the Origin Private File System is much more usable now. One reason that the OPFS is so useful is that, unlike other web abstractions for persisting data, the concept of writing and reading files also makes a lot of sense natively. This is an area that's exciting to me because it opens up the possibility of having one codebase that can run natively (using normal

it does not. i did look into it though [1] and at the time didn't find a good client side vector search lib. i wanted to avoid in-memory vector search since the size of the data can be significant depending on browsing habits. It is definitely possible though. I got a proof of concept working with victor [2] and client-side embeddings but it wasn't good enough IMO to ship.

Curious how this works. I've experimented with in-browser vector search using victor[1] with mixed results. Hadn't heard of this orama lib before checking out your project. [1]: https://github.com/not-pizza/victor

Hey HN, My friend Sam and I were bored one weekend, and wanted to make something self-contained but still useful. We ended up with Victor [0], a vector database designed to run in the browser. It’s written in Rust, which gives us access to things like super-fast and compact serialization and deserialization, but it’s compiled to WASM and uses web-sys to interact with the browser’s JS APIs to write the database contents to disk. We worked hard on designing it in a way that makes sense for the browser. It uses the private origin file system [1] and stores the vectors in a compact format (one byte per vector dimension). Since storage space is at a premium in the browser, we also provide built-in PCA to allow you to compress your vectors. It’s completely transparent to the user and automatically kicks in once a vector storage file exceeds 10m
