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.

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.
What are some alternatives?
buf - The best way of working with Protocol Buffers.
snappy - DEPRECATED - please use https://github.com/Brooooooklyn/snappy. Nodejs bindings to Google's Snappy compression library
