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.

Protobuf-ES: The Protocol Buffers TypeScript/JavaScript runtime we all deserve
My understanding is that the powers that be within Google have decided that validating messages is outside the scope of schemas and serialization. protoc-gen-validate provides a portable way to perform validation: https://github.com/bufbuild/protoc-gen-validate
The problem with required fields is it kicks the can down the road when you want to deprecate a field. Keeping everything optional is much, much better for everyone in the long run.

Why isn't gRPC used more for browser to api transport over REST / graphql?
I built a (go) very rough draft to support 3.1 + a json pointer pkg to support a refactor that was in progress before I bailed on the idea. The amount of effort to get a conventional API was dwarfing that of grpc, especially with protoc-gen-validate.

is there any package to generate validation code for struct instead of using reflect (tags)?
Yes, I am currently using this. I prefer something like this https://github.com/envoyproxy/protoc-gen-validate

sneak peak: code generation extensions to prost (protobuf code generator)
We've been using Rust with protobuf, but had to write lots of conversions from protobuf struct to actual DTO, since prost generates Options for nested types, and does not really support custom types. So I extended prost with the options that we needed. I might aim to also support protoc-gen-validate.

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.
