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.

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

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.

Make Deno MySQL driver works better
Authentication method mismatch is not allowed to occur more than once. It is not a part of MySQL protocol. go-sql-driver also has the same rule.

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.

Which SQL driver to use with Postgres
I'm following Alex Edwards web dev book, he uses MySQL with go-sql-driver/mysql , i want to use Postgres, which one should I use?
-
Are both MySQL and Postgres drivers similar in quality?
go-sql-driver/mysql is the main pure golang implementation and is the most feature complete. Very happy with the result that it provides.
https://github.com/go-sql-driver/mysql/issues/561 , and it's not coming anytime soon

Building RESTful API with Hexagonal Architecture in Go
Instead of directly accessing environment variables with os.Getenv(), integrating a configuration handler like viper might make it maintainable.

Could I get a code review?
Use Viper for config file or environmental variable configuration -- it's going to save you a whole lot of time.

Which packages do you recommend for building cli tools?
Cobra and Viper.

Library for Python similar to Go's Viper / 12 Factor
I've mostly been using https://github.com/spf13/viper of late for my go projects. It supports the standard config formats, (json, yaml, toml etc) and lets you override any value with a ENV value.
-
Two ways to provide configuration: command-line, yaml file.
Not only that, the "unmarshall to struct" method doesn't work at all for environment variables. https://github.com/spf13/viper/issues/188
What are some alternatives?
godotenv - A Go port of Ruby's dotenv library (Loads environment variables from .env files)
envconfig - Small library to read your configuration from environment variables
koanf - Simple, extremely lightweight, extensible, configuration management library for Go. Support for JSON, TOML, YAML, env, command line, file, S3 etc. Alternative to viper.
sqlx - general purpose extensions to golang's database/sql
pgx - PostgreSQL driver and toolkit for Go
kelseyhightower/envconfig - Golang library for managing configuration data from environment variables
cleanenv - ✨Clean and minimalistic environment configuration reader for Golang
mapstructure - Go library for decoding generic map values into native Go structures and vice versa.
ini - Package ini provides INI file read and write functionality in Go
goConfig - goconfig uses a struct as input and populates the fields of this struct with parameters from command line, environment variables and configuration file.
config - JSON or YAML configuration wrapper with convenient access methods.
go-toml - Go library for the TOML file format
