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]

[2] https://github.com/gin-gonic/gin

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!

Questions regarding prepared statements in database/sql
I understand that database/db is an abstraction. As to the driver, sorry, it completely went out of my head. The guide primarily focuses on https://github.com/go-sql-driver/mysql, which is also what I’m interested in.

Finding an Authorization Bypass on My Own Website
> mysql_real_escape_string is still vulnerable when being used with some exotic character sets
Indeed -- mysql_real_escape_string "mostly" fixes this problem by requiring a connection as one of its args, and since it's usually aware of the connection state, it can check that to see if one of those exotic charsets is in-use. But the problem is that there are multiple ways to change the connection charset, some of which the driver is aware of (e.g. in PHP mysqli set_charset) but some it is not (running textual statements like SET NAMES or SET CHARACTER SET).
But generally an attacker won't ever have the ability to set an arbitrary exotic character set for the connection, unless they already have some other sql injection mechanism, in which case it's a moot point :)
Driver documentation also typically mentions this problem. For example, here's the doc for doing client-side param interpolation in the most popular MySQL driver for Golang: https://github.com/go-sql-driver/mysql#interpolateparams
It also explicitly detects if your initial connection settings attempt to use one of those charsets along with param interpolation, and throws an error if so: https://github.com/go-sql-driver/mysql/blob/21f789cd/dsn.go#...
> Couldn't one just save the extra round-trip with length-prefixed strings by sending the query together with the parameters in a single message?
AFAIK, no, not with the traditional MySQL binary protocol. The newer "X protocol" introduced in MySQL 5.7 does allow this, but it is not widely implemented in drivers.

[Question] Working with databases/storing data in Go applications.
However, you can use something like this https://github.com/go-reform/reform to help you with, I will call it automating the code writing. But I have always opted to one of the supported drivers and written a queries myself using for example this https://github.com/go-sql-driver/mysql.
