Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

How we reverse-engineered Google Maps pagination
Google Maps URLs contain the pb parameter contains string-encoded Protobuf. The format is the same as for the data parameter in the browser URL on Google Maps. It contains !-separated values. There are several answers on StackOverflow, gists on GitHub, some blog posts about decoding, and even a kinda official guide on reverse engineering protobuf, but none of this touches pagination.

Add extra stuff to a “standard” encoding? Sure, why not
Seems like protoduf.js has the exact same methods as Google’s implementations with the same names (encode/decode to not prepend with length, encodeDelimited/decodeDelimited for prepending length). It is hard for me to say they’re adding to the standard when they’re just replicating Google’s libraries.

Question about compressing JSON in multiplayer position updates
If it really is a problem, then another option is to use Protobus or Message Pack for serializing (maybe into base64?).

Looking for ideas on how to implement serialization and deserialization between C++ and Javascript
I use protocol buffers. protobufjs translates into json.

GRPC Gateway API Client?
I have tried GRPC gateway generation tools: - PBJS: https://github.com/protobufjs/protobuf.js/
- Protobuf-ES: The Protocol Buffers TypeScript/JavaScript runtime we all deserve
- Did I understand the basic concept of website development with Node Js correctly?
- how can i use protobuf with sveltekit, please?
-
is there any startup or famous web app using grpc/grpc-web for their frontend
We use https://github.com/improbable-eng/grpc-web for the server part with https://github.com/protobufjs/protobuf.js on the frontend.

Parquet-WASM: Rust-based WebAssembly bindings to read and write Parquet data
it's been about 3 years, but in Grafana at the time we were using something like ArrowJS + Arrow Flight + protobuf.js and then render the datasets into dashboards on Canvas, especially for streaming at ~20hz.
when i benchmarked the fastest lib to simply convert the protobuf decode (https://github.com/mapbox/pbf), it was 5x slower than native JSON parsing in browsers for dataframe-like structures (e.g. a few dozen 2k-long arrays of floats).

Outperform Protobuf.js with fixed-size encoding
does it beat https://github.com/mapbox/pbf ?

Protobuf-ES: The Protocol Buffers TypeScript/JavaScript runtime we all deserve
at least in the frontend (without WASM), it depends.
i tested https://github.com/mapbox/pbf and while it was faster for deep/complex structs vs an unoptimized/repetative JSON blob, it was slower at shallow structs and flat arrays of stuff. if you spend a bit of time encode stuff as flat arrays to avoid mem alloc, JSON parsing wins by a lot since it goes through highly optimized C or assembly, while decoding protobuf in the JIT does not.
