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.

tRPC – Move Fast and Break Nothing. End-to-end typesafe APIs made easy
DX for front or back end? The beauty of tRPC is that the types are derived/inferred from the backend runtime code (like, as you type). It would be nigh impossible to do that with grpc(-web) using proto files as the source of truth.
It's possible there's a project out there which could automatically produce proto files from something like zod, json-schema, etc. which could be directly interpreted by TS to provide similar (as you type) DX while still allowing some other language backend to consume the derived proto files (though the DX there would be less than ideal).
If you're just looking for similar TS clients/interfaces for grpc-web then I'd recommend https://github.com/timostamm/protobuf-ts which operates on plain JS objects (no new MyMessage().serialize(), instead the code generator mostly produces TS interfaces for you to work against: const myMessage: MyMessage = pojoConformingToInterface; const binary = MyMessage.toBinary(myMessage);)

gRPC vs REST: Comparing API Styles in Practice
The second big difference is that we now have auto-generated client and server stubs. For this task, I chose to use buf and the protobuf-ts plugin in order to generate idiomatic Typescript classes and objects. Not only do these classes describe the types we'll use in the server and client, but also includes the actual gRPC implementations used to serialize and send messages back and forth across the wire.

Why are gRPC and Node.js so difficult?
I wouldn’t use grpc with web if you can avoid it. If you’re looking for a ts protobuf library I can recommend this one https://github.com/timostamm/protobuf-ts
- GRPC Gateway API Client?

Building a real-time bidding system with Socket.io and React Native
https://github.com/timostamm/protobuf-ts looks interesting too.

Connect-Web: ergonomic Protobuf & gRPC for browsers
I'd recommend looking into protobuf-ts (Timo from Buf) or protobuf-es (Buf maintained).

Rust GRPC
Use a GRPC library for frontend, assuming you want to go with Typescript take a look at https://github.com/timostamm/protobuf-ts Frontend frameworks like Angular/React/Vue don't define what and how to implement backend communication. You can use what you want and how you want it.

Connect: A Better gRPC
And there's also this which is by the same author but came before it: https://github.com/timostamm/protobuf-ts
The latter has code-generation for services and has various transport packages for twirp, grpc, and grpc-web.

Show HN: Pbkit – Protobuf toolkit written in Deno/TypeScript
This looks very interesting! Anything that can move people away from protobuf.js (which seems to no longer be maintained and depends on prototype values for "default values" meaning that you can't send deserialized protobuf messages to/from web workers) and the "native" JS codegen by Google (which produces code that is both very slow and a awkward to use) is a win in my book.
We're currently using https://github.com/timostamm/protobuf-ts which has been fantastic. It's codegen is dependent on the protoc binary as it is implemented as a protoc plugin, but the code it generates passes the protobuf conformance tests. The generated code also outputs plain objects when deserializing protobuf messages which means it works perfectly when sending stuff to/from web workers. It also has grpc, grpc-web, and twirp clients.

tRPC – Move Fast and Break Nothing. End-to-end typesafe APIs made easy
Like generating pydantic models or dataclasses for an OpenAPI schema? I haven't needed to go in that direction myself, but this[0] looks promising!
Apologies if I've misunderstood your comment

OpenAPI v4 Proposal
I'm sorry, but you have completely misunderstood the purpose of Open API.
It is not a specification to define your business logic classes and objects -- either client or server side. Its goal is to define the interface of an API, and to provide a single source of truth that requests and responses can be validated against. It contains everything you need to know to make requests to an API; code generation is nice to have (and I use it myself, but mainly on the server side, for routing and validation), but not something required or expected from OpenAPI
For what it's worth, my personal preferred workflow to build an API is as follows:
1. Build the OpenAPI spec first. A smaller spec could easily be done by hand, but I prefer using a design tool like Stoplight [0]; it has the best Web-based OpenAPI (and JSON Schema) editor I have encountered, and integrates with git nearly flawlessly.
2. Use an automated tool to generate the API code implementation. Again, a static generation tool such as datamodel-code-generator [1] (which generates Pydantic models) would suffice, but for Python I prefer the dynamic request routing and validation provided by pyapi-server [2].
3. Finally, I use automated testing tools such as schemathesis [3] to test the implementation against the specification.

Create Pydantic datamodel from huge JSON file with local datamodel-code-generator
The site also provide a link to the github repo of the underlying program.
-
PSA: I think this JSON to Pydantic converter is extremely useful for boilerplate model creation
Not sure who owns/hosts the site, but its based on this github repo.

My top python library
That's what datamodel-code-generator propose.

What's the best libraries to build a REST API with Openapi compatibility
To save you some work, if you have already an OpenAPI specification at hand, you can use datamodel-code-generator to generate your Pydantic models from the spec.

This is what I pushed today, I don't know why but I was very positive about the code until someone reviewed it and pointed out the obvious. Also 'internal_data' field is very essential for other parts of the code. It is so embarrassing I want to disappear from the face of the earth.
And there are code generators for it! https://github.com/koxudaxi/datamodel-code-generator/
