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.

Understanding gRPC Concepts, Use Cases & Best Practices
Note: gRPC services can also be tested from CLI using tools like evans-cli. But for that reflection needs (if not enabled the path to the proto file is required) to be enabled in gRPC servers. This compare link shows the way to enable reflection and how to enter into evans-cli repl mode. Post entering repl mode of evans-cli, gRPC services can be tested from CLI itself and the process is described in evans-cli GitHub page.

grpcurl-like tool for grpcweb
I use Evans, it supports gRPC and gRPC-web and also supports reflection protocol.

Go and gRPC is just so intuitive. Here's a detailed full-stack flow with gRPC-Web, Go and React. Also, there is a medium story focused on explaining how such a setup might boost efficiency and the step-by-step implementation.

Postman-powered testing of Akka Serverless gRPC APIs
Over the holidays, 2021, Postman gifted a fine upgrade to its users: beta support for the gRPC protocol in its API platform. As a Product Manager for Lightbend and helping out on its new gRPC native PaaS for building and running APIs and microservices, I was excited, to say the least. In another, recent blog post, I mentioned my desire to leverage UI test-and-try tools for APIs (my time in the REST API world of Mashery and PubNub was the source of such desire). In that same post though, I noted the lack of several important gRPC features, like server reflection and more robust import capabilities, as blockers; hence, my deep dive, in that post, into the CLI tool, Evans.

gRPC test-and-try with Akka Serverless and Evans
And who am I kidding? I'm a CLI-type person. Which is why I was super excited to stumble about Evans. Within minutes, I had gone from installation to trying out TLS-secured APIs and microservices running in the cloud on Lightbend's new serverless offering.

Set Up Grpc Web Server With AWS
If everything is set up correctly, you should now be able to use evans to access your web server at the load balancer url or even the url for your ec2 instance directly e.g.

Setting Up a gRPC Protobuf Server With Tonic
After running the server with cargo run, I needed a way to test that the server works. I had heard of an interesting tool called evans, so I decided to use this. It took me a while to figure out the right parameters to query the server, especially because tonic doesn't seem to support gRPC reflection right now, and there are few examples out there.

5 Open Source tools written in Golang that you should know about
The Buf CLI is a versatile tool designed for handling Protocol Buffers (Protobuf), a method of serializing structured data. It offers several key features, including managing Protobuf assets through the Buf Schema Registry (BSR), providing a linter to enforce optimal API design and structure, and a breaking change detector to maintain compatibility either in source code or at the wire level. Additionally, the Buf CLI includes a generator that activates plugins based on user-defined templates and a formatter to standardize the formatting of Protobuf files according to industry norms. It also integrates seamlessly with the Buf Schema Registry, supporting comprehensive dependency management.

We'll use the Buf CLI as an alternative to protoc so that we can save our generation configuration as YAML. Buf is compatible with protoc plugins.

Flutter + gRPC for Desktop and Mobile App Development - Good choice?
In my opinion it's a good idea, it's the architecture we use at work, and it works well for us. The main limitation to be aware of is that many PaaS don't support gRPC traffic (because of the proxies used). For example, DigitalOcean App Platform or Heroku if I remember correctly. If the way you want to host your backend is OK with HTTP/2 and gRPC traffic, then it's not a limitation. One way around this limitation is to use the gRPC-Web protocol, or the Connect protocol (https://connect.build/). Unfortunately, Dart's gRPC client does not support the gRPC-Web protocol outside the web platform. So for a mobile application, it's not usable at the moment. (If this PR were accepted, it would solve the issue: https://github.com/grpc/grpc-dart/pull/557.) As for Connect, no client is currently offered by Buf for Dart. Don't hesitate if you want to know more. That said, I'd advise you to use the Connect implementation for Go to implement your backend. Connect will enable your server to speak all three protocols (gRPC, gRPC-Web and Connect), which is very useful in the long term. What's more, the code is cleaner, and you benefit from official support for observability with OpenTelemetry. If you don't know Buf (the creators of Connect),I suggest you visit their website: https://buf.build/. :-) Good luck!

Building High-Performance Web Services with Golang gRPC
gRPC itself is quite nice, especially with buf which makes generating Go code much easier. The rest of the code was in a bad state. Unmaintained router packages, repository pattern without any actual benefit or a repository pattern.

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.

Issues with proxying gRPC services to web, and a potential prototype
Consider checking out https://connect.build from https://buf.build. Supports a simpler protocol than grpc-web. Includes a js/ts client for frontend. Then you don’t necessarily need a rest layer, but could leverage the proxy your building.
