I think crossing a language barrier here would be hard: you'd need a codegen step to compile the RPC spec to Typescript for the client-side DX and that would need take into account the full range of differences in serializability across the languages.

For cross-language RPC, I think we're still better sticking to a well defined system where the spec is data (OpenAPI, GraphQL, etc.) instead of the spec being code that only one side understands.

This seems really cool and I'd be happy to help (I'm currently a pgtyped + Kysely user and community contributor), and I see how this solves n+1 from promise pipelining when fetched "nested" data with a similar approach as Cap'n Web, but I don't we've solved the map problem.

If I run, in client side Cap'n Web land (from the post): ``` let friendsWithPhotos = friendsPromise.map(friend => { return {friend, photo: api.getUserPhoto(friend.id))}; } ```

And I implement my server class naively, the server side implementation will still call `getUserPhoto` on a materialized friend returned from the database (with a query actually being run) instead of an intermediate query builder.

@kentonv, I'm tempted to say that in order for a query builder like typegres to do a good job optimizing these RPC calls, the RpcTarget might need to expose the pass by reference control flow so the query builder can decide to never actually run "select id from friends" without the join to the user_photos table, or whatever.

My understanding is that your first read is right and your current understanding is wrong.

The client sends over separate 3 calls in one message, or one message describing some computation (run this function with the result of this function) and the server responds with one payload.

This seems great and I'm really excited to try it in place of trpc/orpc.

Although it seems to solve one of the problems that GraphQL solved that trpc doesn't (the ability to request nested information from items in a list or properties of an object without changes to server side code), there is no included solution for the server side problem that creates that the data loader pattern was intended to solve, where a naive GraphQL server implementation makes a database query per item in a list.

Until the server side tooling for this matures and has equivalents for the dataloader pattern, persisted/allowlist queries, etc., I'll probably only use this for server <-> server (worker <-> worker) or client <-> iframe communication and keep my client <-> server communication alongside more pre-defined boundaries.

It’s the same - just saying it works in both.

I like it because I can do full stack development, including the database, with a single system level dependency (Bun).

I have this setup and integrated for Node/Bun -

This is an example of a unit test of an API route on a fully isolated WASM backed Postgres - very few lines of code, and all your API unit tests can run fully in parallel without any shared state: https://github.com/ben-pr-p/bprp-react-router-starter/blob/m...

This is all of the code needed to use Postgres in prod and PGLite in test/dev: https://github.com/ben-pr-p/bprp-react-router-starter/blob/m...

As someone who: - would love to self host, and would much prefer keeping it to Postgres / Redis for which there is widespread knowledge on how to host - would like you to keep your development velocity up

I'd encourage you not to switch databases, or at least to defer this for a while. I can't imagine you'll have issues with the amount of WAL written for quite a while, and by that time, the world could be quite different (OrioleDB might be mature! https://github.com/orioledb/orioledb)

This is really great. I was hoping someone would build this: https://bprp.xyz/__site/Looking+for+Collaborators/Better+Loc...

I would really happily pay $10 / month for this, but what I really want is either: - A Raycast plugin or Desktop app that lets this interact with any editable text area in my environment - An API that I can pass existing text / context + audio stream to and get back a heartbeat of full document updates. Then, the community can build Obsidian/VSCode/browser plugins for the huge surface area of text entry

Going to give you $10 later this afternoon regardless, and congrats!

Going to be sharing this snippet with non-technical friends and family:

“ SIMA agents trained on a set of nine 3D games from our portfolio significantly outperformed all specialized agents trained solely on each individual one. What’s more, an agent trained in all but one game performed nearly as well on that unseen game as an agent trained specifically on it, on average”

Many people I talk to assume that when a LLM gets something right, it’s because that specific thing was in the training set. Although the experience of human transfer learning is intuitive to people, I find people have a hard time appreciating that it can happen in algorithms too.

This action undermines Israel’s blockade, and could be seen as an act of war, so it’s important the US lead the effort.

The article does mention that other countries are participating and helping as well though.

What’s embarrassing here for the US is that they have to basically force the aid in. They don’t seem willing to use their full leverage to let the aid in the normal way
