Golang resource inventory: to help you in your programming journey

As a Golang developer, you need to obtain high-quality learning and community resources to improve your skills. Here is a comprehensive guide to the best tutorials, books, and communities in Golang:

Best Tutorials

• Golang Official Tutorials: Comprehensive and authoritative Golang getting started guide.

  package main
  
  import "fmt"
  
  func main() {
    fmt.Println("Hello, Golang!")
  }

  Copy after login

• Codecademy Go Courses: Interactive tutorials covering basics to advanced concepts.

  // 定义一个结构体
  type Person struct {
    Name string
    Age int
  }
  
  // 创建一个结构体实例
  tom := Person{Name: "Tom", Age: 25}

  Copy after login

• Udemy Golang Bootcamp: In-depth online courses, from zero basics to practical projects.

  // 创建一个 goroutine
  go func() {
    fmt.Println("并发执行")
  }()

Recommended books

• "Go Programming Language" (book):Robert Griesemer, Rob Authoritative book written by Pike and other Go language founders.
• "The Go Programming Language: By Example": A practical guide to easily understand Golang concepts.
• 《Concurrency in Go》:Explore advanced techniques of parallel and concurrent programming.

Community

• Golang Official Forum: The official channel to discuss issues, seek help and make suggestions.
• Golang subreddit: Active Reddit community sharing news, tips, and resources.
• Gophers Slack: Join a large Slack community of Golang developers for real-time communication.

Practical case

• Build a simple REST API: Using gorilla/mux and go-chi Wait for the library to create a RESTful web service.

  // 路由器
  r := mux.NewRouter()
  r.HandleFunc("/user", userHandler)
  
  // 启动服务器
  log.Fatal(http.ListenAndServe(":8080", r))

  Copy after login

• Handling concurrent tasks: Use goroutine and channels to process parallel tasks and improve performance.

  // 创建一个通道
  ch := make(chan int)
  
  // 启动 goroutine
  go func() {
    ch <- 10
  }()
  
  // 从通道中读取并打印
  x := <-ch
  fmt.Println(x)

• Connect and query the database: Use libraries such as gorm or xorm to interact with the database.

  import (
    "fmt"
    "github.com/jinzhu/gorm"
  )
  
  type User struct {
    ID   uint
    Name string
  }
  
  func main() {
    db, err := gorm.Open("mysql", "user:password@tcp(localhost:3306)/database")
    if err != nil {
        panic(err)
    }
  
    // 查询用户
    var users []User
    db.Table("users").Find(&users)
  
    for _, user := range users {
        fmt.Println(user.Name)
    }
  }
