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: Good examples of Go back ends?
Most golang backends I've seen meanwhile use or switched to using the "gin" framework to build their APIs.
A lot of them also have conventions for the frontend, where the assets usually are stored in /public, so they can be go:embed later as an embed.FS instance into the binary.
Having said that, there's plenty of examples on github. I'd recommend to take a look at bigger projects or templates and understand how they structured their packages and abstraction levels. E.g. go-admin comes to mind [1]

From Laravel to Sponge: How to Easily Develop Web Services with Golang
Excellent Performance: Sponge is built on the gin framework, providing outstanding performance for web service development.

Generate project code for a general web service(gin) to increase your development efficiency by 10 times
The web framework uses gin. It also includes swagger documents, common service governance function codes, and build and deployment scripts. You can choose which database to use.

Fundamentals to Learn
When it comes to Web Development I would recommend taking a closer look at some standard library packages like net and encoding. Looking at some Web Development open-source frameworks / libraries might be helpful as well. Gin is one of them.

Tools besides Go for a newbie
IDE: use whatever make you productive. I personally use vscode. VCS: git, as golang communities use github heavily as base for many libraries. AFAIK Linter: use staticcheck for linting as it looks like mostly used linting tool in go, supported by many also. In Vscode it will be recommended once you install go plugin. Libraries/Framework: actually the standard libraries already included many things you need, decent enough for your day-to-day development cycles(e.g. `net/http`). But here are things for extra: - Struct fields validator: validator - Http server lib: chi router , httprouter , fasthttp (for non standard http implementations, but fast) - Web Framework: echo , gin , fiber , beego , etc - Http client lib: most already covered by stdlib(net/http), so you rarely need extra lib for this, but if you really need some are: resty - CLI: cobra - Config: godotenv , viper - DB Drivers: sqlx , postgre , sqlite , mysql - nosql: redis , mongodb , elasticsearch - ORM: gorm , entgo , sqlc(codegen) - JS Transpiler: gopherjs - GUI: fyne - grpc: grpc - logging: zerolog - test: testify , gomock , dockertest - and many others you can find here

Looking to build a small team for a start-up idea
The back-end is going to be written in Golang, using a Gin, Gorm, and a Postgres DB, so bonus points if you are familiar with Go!

Can an API be merely a server that has post requests sent to it, rather than something that is installed?
Here's Express for Node.js, Flask for Python, Alfred for Dart, and Gin for Go; that's four different software packages for four completely different programming languages that all do very similar things. Take a look and see which one feels best, and start from there!

Gopher Pythonista #1: Moving From Python To Go
Another useful tool in Go is the go vet command, which helps to identify common coding mistakes such as unreachable code or useless comparisons. In addition, external linters like staticcheck can be used to detect bugs and performance issues with ease.

Find project-wide unused code using Golang's LSP
For the last year or so (as of 2023) Golang has only had one active project for linting unused code, namely: unused from https://github.com/dominikh/go-tools. It works really well, but only within a package, not across packages, like within a traditional monolith. unused used to be part of another project called staticcheck, that did indeed have a flag for detecting project-wide unused code, but that is no longer supported. There are good reasons for that (see this Github discussion), mainly that it's computationally expensive.

Why tf golang let's you create maps with duplicated keys
To a degree, sure. It can't pick it up in general, because of the halting problem. But some trivial cases could be caught. Feel free to write such a linter, I'm sure Dominik would gladly merge it, for example.

New linter for mixing pointer and value method receivers
Also proposal to staticcheck, will see if it goes through! https://github.com/dominikh/go-tools/issues/1337

this result of append is never used, except maybe in other appends (SA4010)
This is the first result for that error in google. The comment in that issue explains it. You're building two array's c_code, and c_start_date which are built and then never read or returned or otherwise used.

Zig, the Small Language
This really irritated me when I started working with go, but it stopped bothering me and now I even mostly like it.
The missing error checks are annoying, but if you have appropriate editor config it is hard to miss them: https://cdn.billmill.org/static/newsyctmp/warning.png
Basically writing go without `staticcheck`[1] is not recommended. If you do have it set up, it's pretty easy to avoid simple errors like that.

Our experience upgrading from go v1.17 to v1.18 for generics
However, recently [per this issue](https://github.com/dominikh/go-tools/issues/1270) it is safe to re-enable the ones I highlighted with strikethrough above. I would be interested in tracking issues for the remainder if you have those linked somewhere.

What are your strategies to prevent nil pointers errors in your code base?
Unfortunately I don't know of any tools that can/do always detect it. There's this discussion for the staticcheck linter where they basically don't think it's worth false positives in order to support it a lint for it.
