How to Build and Document a Go REST API with Gin and Go-Swagger
Now let’s define the functions that will be called whenever a request hits our API. All the functions will be referencing the context provided by the Gin web framework. Paste the following code below the sample slice we just added to api.go:
- Autenticação com Golang e AWS Cognito

Implementing JWT Authentication in a Golang Application
Now, let's dive into the fun part – creating our basic ToDo application using the powerful Gin framework. This section will walk you through the steps, breaking down the code into manageable snippets.

Build a Serverless GenAI solution with Lambda, DynamoDB, LangChain and Amazon Bedrock
Thanks to the AWS Lambda Web Adapter, the application built as a (good old) REST/HTTP API using a familiar library (in this case, Gin.

Uploading and Serving Images from MongoDB in Golang
In this blog, we will delve into the fascinating realm of handling images in a Golang application, leveraging the power of the Gin framework for RESTful API development, MongoDB as a robust NoSQL database, and the mongo-driver library for seamless interaction with MongoDB. To store images efficiently, we'll explore the intricacies of GridFS, a specification within MongoDB for storing large files as separate chunks.

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.

Different CORS settings for different paths?
I have created an application with Go in Gin-Gonic. In my frontend (Nuxt3/TypeScript) I always get a CORS error:

Rapid Prototyping of Design-First APIs in Go
We use Gin web framework https://gin-gonic.com for the routing, Gin provides a balance between performance, ease of use and extensibility making it a preferred choice for building and running web applications in Go.

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. https://github.com/gin-gonic/gin), 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...

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
