What are the sub-communities of the golang framework community?

The Go framework community contains many sub-communities that focus on specific types of applications and functionality. These include Echo, Gin, and Goji for web development, Ent, GORM, and Viper for back-end services, Colly, MQTT, and grpc for network and infrastructure, and NumPy, SciPy, and TensorFlow for data science and machine learning. , and other frameworks that help build specific functionality, such as Casbin, Echo-WebSocket, Negroni.

Forks of the Go Framework Community

The Go Framework Community is a vibrant and diverse ecosystem that brings together many dedicated A subcommunity focused on a specific type of application or feature. Understanding these communities is critical to participating in projects and finding proprietary knowledge.

Web Development

• Echo: A lightweight, high-performance web framework ideal for building APIs and microservices.
• Gin: A high-performance web framework built on net/http, providing flexible routing and middleware systems.
• Goji: Flexible Sinatra-inspired web framework that provides powerful routing and middleware capabilities.

Backend Services

• Ent: Automatic code generation tool for creating and managing relational database schemas.
• GORM: An ORM for the Go standard library database/sql, making it easy to interact with relational databases.
• Viper: A lightweight configuration framework for managing application configuration.

Network and Infrastructure

• Colly: A powerful and flexible network library for writing web crawlers.
• MQTT: Message broker library for Internet of Things (IoT) applications.
• grpc: High-performance, language-agnostic RPC framework developed by Google.

Data Science and Machine Learning

• NumPy: Basic library for numerical calculations and data manipulation.
• SciPy: A collection of add-on modules for scientific and technical computing.
• TensorFlow: An open source framework for deep learning and machine learning.

Others

• Casbin: A framework for authorization and access control.
• Echo-WebSocket: WebSocket plugin for the Echo framework.
• Negroni: A framework for connecting middleware and building HTTP handler stacks.

Practical case

Suppose we want to build a simple API to obtain user data. We can use the Gin framework to quickly set up routes and handlers. The following code shows how to handle a simple GET request:

package main

import (
    "github.com/gin-gonic/gin"
)

func main() {
    r := gin.Default()
    r.GET("/users", func(c *gin.Context) {
        c.JSON(200, gin.H{
            "users": []string{"Alice", "Bob", "Carol"},
        })
    })
    r.Run()
}

This will create an API that will run on port 8080. You can test this by sending a GET request to the /users endpoint from an HTTP client such as curl or Postman.
