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.

While Learning Haskell Developing Project
Hello guys im a self teach coder. im working with golang atm because this great project speed up my learning curve: https://github.com/MarioCarrion/todo-api-microservice-example

Open source projects to look at for best practices?
With that being said, if you're looking for something friendlier, I share my own educational repo, still a WIP but it should help you with the basics.

Is there a standard file in Golang from which packages could be installed? Yes, I am aware about go.mod, but hear me out.

Hexagonal architecture and mocking
You are going to need to add a domain package where the Beer type and all the logic associated to that type is defined to avoid the cyclical dependency. I typically follow this approach by using internal as the domain package that then other packages like services, data stores or transport use.

DDD file structure & cyclic dependencies
Here's my approach; a few worth-mentioning packages in there: * service defines the use cases, it's a glue between the domain model and repositories. * rest defines the http handlers uses the service types via dependency injection (see main.go) * postgresql concrete repository example (there are other implementations for other data stores like kafka, redis, etcetera.

Example of a well written and structured RESTful API or web service?
Other redditors mentioned some good resources, I'm going to shamelessly plug mine as well; either way after you are done with whatever tutorial you use I recommend you to look at the Exposure Notifications Server, reading the source code should help you learn other best practices.

Golang for backend
One word of advise I can give you is that building a production-grade microservice in Go takes a bit; not because of the language but because you have consider the tradeoffs when choosing different packages to connect everything to make it work (because there's no Django, Ruby on Rails or Spring), I have an educational repository (still work in progress) trying to describe what I've learned from the last 5 years after successfully deploying multiple services to production where multiple engineers contribute and collaborate together; perhaps that could help you.

How to avoid "import cycle not allowed" when defining related models in different packages?
With all of that being said I have an educational repository demonstrating this structure, I've been using it in real life for about 5 years already and I've successfully delivered services to production multiple times where multiple engineers contribute and collaborate together.

Good example of production grade rest api without an ORM
You may want to checkout the "Exposure Notifications Server" project; I also have a similar (educational) project that uses the Repository Pattern.

Show HN: Riza – Safely run untrusted code from your app
Hi HN, I’m Kyle and together with Andrew (https://news.ycombinator.com/user?id=stanleydrew) we’ve been working on Riza (https://riza.io), a project to make WASM sandboxing more approachable. We’re excited to share a developer preview of our code interpreter API with HN.
There’s a bit of a backstory here. A few months ago, an old coworker reached out asking how to execute untrusted code generated by an LLM. Based on our experience building a plugin system for sqlc (https://sqlc.dev), we thought a sandboxed WASM runtime would be a good fit. A bit of hacking later, we got everything wired up to solve his issue. Now the API is ready for other developers to try out.
The Riza Code Interpreter API is an HTTP interface to various dynamic language interpreters, each running inside a WASM sandbox without access to the outside world (for now). We modeled the API to align with a POSIX shell-style interface.
We made a playground so you can try it out without signing up: https://riza.io
The API documentation lives here: https://docs.riza.io
There are many limitations at the moment, but we expect to rapidly expand capabilities so that programs can e.g. access the network and filesystem. Our roadmap has more details: https://docs.riza.io/reference/roadmap
If you need to execute LLM-generated code we’d love to have you try the API and let us know if you run into any issues. You can email us directly at [email protected].

Show HN: Sqlbind a Python library to compose raw SQL
I came across this yesterday for golang: https://sqlc.dev which is somewhat like what you want, maybe.
Not sure it allows you to parameterize table names but the basic idea is codegen from sql queries so you are working with go code (autocompletion etc).

ORMs are nice but they are the wrong abstraction
Agreed, but tools like https://sqlc.dev, which I mention in the article, are a good trade-off that allows you to have verified, testable, SQL in your code.

Go ORMs Compared
sqlc is not strictly a conventional ORM. It offers a unique approach by generating Go code from SQL queries. This allows developers to write SQL, which sqlc then converts into type-safe Go code, reducing the boilerplate significantly. It ensures that your queries are syntactically correct and type-safe. sqlc is ideal for those who prefer writing SQL and are looking for an efficient way to integrate it into a Go application.

Type-safe Data Access in Go using Prisma and sqlc
I was browsing awesome-go for ideas on how to setup my data access layer when I stumbled on sqlc. It seemed like a great option. Code generation is a strategy often used in the Go ecosystem and making my queries safe at compile time was an idea I really liked. Knex was great, but it required of me that I test thoroughly my queries at runtime and that I sanitize my query results to ensure type safety within my application.
