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.

Ask HN: WebSocket server transforming channel subscriptions to gRPC streams
* Additionally, client can stream data to the backend server (if bidirectional GRPC streams are used). I.e. client sends WebSocket messages, those will be transformed to GRPC messages by WebSocket server and delivered to the application backend.
As a result we have a system which allows to quickly create individual streams by using strict GRPC contract but terminating connections over WebSocket transport. So it works well in web browsers. After that no need to write WebSocket protocol, client implementation, handle WebSocket connection. This all will be solved by a suggested WebSocket server and its client SDKs.
The mechanics is similar to Websocketd (https://github.com/joewalnes/websocketd), but instead of creating OS processes we create GRPC streams. The difference from grpc-web (https://github.com/grpc/grpc-web) is that we provide streaming capabilities but not exposing GRPC contract to the client - just allowing to stream any data as payload (both binary and text) with some wrappers from our client SDKs side for managing subscriptions. I.e. it's not native GRPC streams on the client side - we expose just Connection/Subscription object to stream in both directions. GRPC streams used only for communication between WebSocket server and backend. To mention - grpc-web does not support all kinds of streaming now (https://github.com/grpc/grpc-web#streaming-support) while proposed solution can. This all should provide a cross-platform way to quickly write streaming apps due to client SDKs and language-agnostic nature of GRPC.
I personally see both pros and cons in this scheme (without concentrating on both too much here to keep the question short). I spent some time thinking about this myself, already have some working prototypes – but turned out need more opinions before moving forward with the idea and releasing this, kinda lost in doubts.
My main question - whether this seems interesting for someone here? Do you find this useful and see practical value?

gRPC vs REST: Comparing API Styles in Practice
Since we're using Envoy, there's one more neat trick that we can employ. It turns out that Envoy also support gRPC-Web out of the box, a JavaScript client designed to support gRPC communication from the browser! That means that we can send gRPC messages over HTTP/1.1 as base64 encoded strings or as binary protobufs. Messages will be sent through our proxy and on to our backend service. The advantage of this is smaller and more efficient wire communication which should lead to better performance.

Ask HN: Why isn't JSON-RPC more widely adopted?
Personally, find gRPC-Web very attractive but the current state of TypeScript/JS code-gen is very confusing and lacking.
I would love something like https://orval.dev for gRPC-web. Have I missed something or is it just early to expect it?
I tried a few libraries but couldn't get them to work or would generate unappealing results. I believe I'm hitting this issue with my local experiments. https://github.com/grpc/grpc-web/issues/535

You worked on it? Why is it slow then?
Seeing this I went right into the code and found the gem, grpc-web is responsible for browser support. Official Docs

REST vs. gRPC vs. GraphQL
Hasura makes that pretty easy as can be seen here: https://github.com/firatoezcan/hasura-cms
This is also easy to do with self-written servers, maybe take a look at the metadata folder to get a gist of what Hasura would be doing behind the scenes (running a query and then checking the claim for the condition for the given field that permission wants to be requested for)
(Just a repo I started one evening, it doesn't do much but the concept of projects with owners and collaborators should work)
