flatbush VS connect-es

> (There are ECS frameworks in JavaScript, which gives you absolutely no control over memory layout and thus completely defeats one of the primary purposes of the pattern.)

While JS does not provide great support for bit packing complex structs, typed arrays give you quite a bit of control over memory layout for simple numeric types, which is what you usually want for optimal data-oriented code anyway. This is a common technique used in fast JS libs for data visualization, ie:

https://github.com/mourner/flatbush

There are also basic operators required for bitarrays, which are useful for ECS and memory-efficient code generally.

using flatbush library instead of rbush which optimise the statically placed element, from the benchmark in the repository it could boost up to 5x the performance of rbush.

But for 500 k points, it's not many. I'd put it in the database tech I was using and hit an API for it. Or like you say, load it into memory and use Mourner's flatbush for a super simple and super fast solution..

> At pbf speeds, decoding is usually no longer a bottleneck, but bandwidth might be when comparing with gzipped JSON.

we were streaming a few hundred datapoints in a dozen flat arrays over websocket at 20-40hz and needed to decode the payload eagerly. plain JSON was a multi-factor speedup over pbf for this case. but it's fully possible i was holding it wrong, too!

even if your "bottleneck" is rendering/rasterization (10ms), but your data pipe takes 5ms instead of 1ms, it's a real effect on framerate, battery, thermals, etc.

i'm a big fan of your work! while i have you here, would you mind reviewing this sometime soon? ;)

> However, it's important to note that browser support wasn't a primary focus in gRPC's design. This oversight necessitates an additional component, grpc-web, for browser accessibility. Furthermore, external services often have specific needs like caching and load balancing, which are not directly catered to by gRPC. Adopting gRPC for external services might require bespoke solutions to support these features.

The article should mention the Connect protocol for web-based Protobuf messaging:

https://connectrpc.com/

We can solve this with a service! Now there are many ways I could have started, but I decided to test out gRPC along the way. This was a mistake. I hoped for the best, but gRPC ended up not being a good choice for the web client. Why? you ask. The gRPC protocol works with all the bells and whistles of http when used server to server, but web clients are not as great. The Javascript client is dependent on http 2.0, and it requires a proxy like Envoy to work with a browser. What's more, I didn't love the structure of the generated web client. So through the process of working on this 'local first stack' I actually got sucked in to a big rabbit hole in making the rpc system work. I ended up going with Connect which is a tool that can create a service from a protobuf service definition, that also talks a simple http 1.1 protocol. What ultimately sold me on this solution as the best is that it also came with a very nice to use web client generation, and even plugs in to my favorite react http helper useQuery.

Our stack at Escape is written in multiple languages because each team has specific needs. We use TypeScript for its vibrant ecosystem, Python for cybersecurity research and Go for performance-sensitive tasks. To orchestrate cross-language task orchestration, we first developed a simple request-response protocol over HTTP, but it wasn't sustainable as the Escape codebase grew rapidly. We evaluated several technologies to replace our homegrown protocol, and two emerged as the most promising options: Connect and Temporal. The title gives it away, but the reason is far from obvious

protobuf messages we’ll configure (@bufbuild/connect-es)

try https://github.com/bufbuild/connect-web

As for better gRPC-web, you might want to look into connect-web https://github.com/bufbuild/connect-web

They already have! Connect (https://github.com/bufbuild/connect-web) is what you're looking for, as it's grpc-web compatible.

Ye, fwiw there is an example code size comparison here:

https://github.com/bufbuild/connect-web/blob/main/packages/c...

I'm sure someone will chime in on the implementation details, but hopefully others can give it a try with their projects!
