viper VS Gin

Compare viper vs Gin and see what are their differences.


Go configuration with fangs (by spf13)


Gin is a HTTP web framework written in Go (Golang). It features a Martini-like API with much better performance -- up to 40 times faster. If you need smashing performance, get yourself some Gin. (by gin-gonic)

    Use Viper for config file or environmental variable configuration -- it's going to save you a whole lot of time.

    I've mostly been using 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.

    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

  • Building RESTful API with Hexagonal Architecture in Go

    For building the RESTful Point of Sale service API, I've considered and selected a combination of technologies that would work seamlessly together. For handling HTTP requests and responses, using the Gin HTTP web framework would make sense because I think it seems complete and popular among Go community too. To ensure data integrity and persistence, I'm using PostgreSQL database with pgx as the database driver, the reason I choose PostgreSQL because it is the most popular relational database to use in production and offers efficient Go integration. I'm also implementing caching using Redis with go-redis client library, which provides powerful in-memory data storage capabilities.

    It uses Gin as the HTTP framework and PostgreSQL as the database with pgx as the driver and Squirrel as the query builder. It also utilizes Redis as the caching layer with go-redis as the client.

  • Goravel, Web framework inspired from Laravel in Golang

    That's not a problem with Go, it's a problem with frameworks: they give you some abstractions, e.g. the Laravel query builder, but they don't cover all the use cases, so you quickly find yourself using "raw" queries anyway.

    There are some well-established web frameworks for Go (e.g., but they are controversial too, as most Go developers seem to prefer libraries (that your code calls) instead of frameworks (that call your code and impose their structure upon it). So I don't think just cramming a framework from a completely different language into Go will fly...

    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.

    For building my web server, I chose to use the Gin framework as the foundation of my app. It was incredibly easy to understand and work with, and I was pleasantly surprised by how seamlessly it integrated with writing unit tests for the server. To handle the database, I leveraged the power of go-sqlite and migrate for efficient SQL queries and migrations. These libraries proved to be both powerful and user-friendly, making the development process a breeze.
