Resources provided by the Go framework community

The Go framework community provides a wealth of resources to help developers build robust, high-performance applications. These resources include:

Libraries and Frameworks

• Echo Framework: Lightweight, fast, and easy-to-use web framework.
• Gin Framework: High performance, scalable web framework with flexible routing.
• GORM: ORM (Object Relational Mapper) for MySQL, PostgreSQL, SQLite and other databases.

Documentation and tutorials

• Go language official documentation: Comprehensive and detailed introduction to all aspects of the Go language.
• Go framework tutorial: Provides a wide range of framework tutorials, including Echo, Gin and GORM.
• Community blogs and articles: Written by experienced developers, providing insights and best practices about the Go framework.

Tools and Utilities

• GoLand IDE: An integrated development environment (IDE) designed specifically for Go developers , providing functions such as code completion, debugging, and refactoring.
• Swagger: A specification for defining and managing API interfaces.
• Prometheus: Monitoring system for monitoring and alerting.

Community Support

• Go Forum: Official online forum where developers can exchange questions and share knowledge.
• Go Community Slack: A chat platform that allows developers to connect and collaborate in real time.
• Go Conference: Regularly held conference where developers can learn about the latest Go technology and insights.

Practical case

Build a simple Web API

package main

import (
    "github.com/labstack/echo/v4"
)

func main() {
    e := echo.New()
    e.GET("/", func(c echo.Context) error {
        return c.String(200, "Hello World!")
    })
    e.Logger.Fatal(e.Start(":8080"))
}

Using the Echo framework, you only need a few Create a Web API that handles HTTP requests with just a few lines of code.

Connect to the database

package main

import (
    "database/sql"
    _ "github.com/go-sql-driver/mysql"
)

func main() {
    db, err := sql.Open("mysql", "user:password@tcp(localhost:3306)/database")
    if err != nil {
         panic(err)
    }

    rows, err := db.Query("SELECT * FROM users")
    if err != nil {
        panic(err)
    }

    for rows.Next() {
        var id int
        var name string
        if err := rows.Scan(&id, &name); err != nil {
            panic(err)
        }
        fmt.Println(id, name)
    }

    db.Close()
}

With GORM, you can easily connect to the database and query data using simple and clear code.
