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]

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

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!

Error handling in Go web apps shouldn't be so awkward
The three behaviors I've described that we want all depend on two things, the first of which is "idiomatic error handling". We need to be able to simply return err in our handlers. Unfortunately, the standard libray doesn't give us this. But some third-party frameworks do. The most popular one I'm familiar with is labstack echo, whose HandlerFunc looks like this:

Could I get a code review?
Use a library for HTTP serving, such as Gin, Chi, or Echo. I personally use Chi, as it's just the right level of abstraction for how I like to work. Despite what others say here, don't try to re-implement everything in a modern serving library using the standard library.

It's so easy to learn
Here I'm not really sure what you're referring to: * You can set request timeout and it has nothing to do with whether you handled your error or not. * In most cases you either bubble it up the callstack or do something with error in place you o received it i.e. you switch to default value, retry or sth along those lines. In some cases frameworks like echo will translate error into 5XX response for you if you don't do anything with it in top level handler. * Panics are recoverable. Also in case your handler panics it won't crash entire server -> stdlib HTTP server just closes connection, frameworks might even provide panic handler which will return 5XX instead of nothing. * try/catch doesn't really solve anything I mentioned here ¯_(ツ)_/¯. You just hope somebody caught your exception somewhere else.
