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")
    }()
    Copy after login

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)
    Copy after login
  • 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)
      }
    }
    Copy after login

By taking advantage of these resources, you can improve your Golang skills, build powerful applications, and connect with like-minded developers.
