Go from Beginner to Expert: A Complete Guide to Learn Golang PART-17
Step-by-Step Guide to know about Golang tools and frameworks in Golang.
Welcome to our tutorial on Golang tools and frameworks. If you’re a Golang developer or just starting out with the language, you’re probably wondering what tools and frameworks can help you make development faster and easier.
If you want to read the previous post, you may check it out here.
In this tutorial, we’ll introduce some popular Golang tools and frameworks and explain how they can simplify your Golang development.
First, let’s talk about choosing the right library or framework for your project. With so many options available, it can be challenging to know which one to use.
Some popular frameworks for web development include Gin, Echo, and Beego.
Gin is known for its speed and low memory usage, while Echo is known for its simplicity and flexibility.
Beego is a full-stack web framework that provides ORM, routing, and other features out of the box.
For microservices, you might consider frameworks like Go Micro or KrakenD.
Gin example
package main
import "github.com/gin-gonic/gin"
func main() {
r := gin.Default()
r.GET("/", func(c *gin.Context) {
c.JSON(200, gin.H{
"message": "Hello, world!",
})
})
r.Run() // listen and serve on 0.0.0.0:8080 (for windows "localhost:8080")
}Echo example
package main
import "github.com/labstack/echo/v4"
func main() {
e := echo.New()
e.GET("/", func(c echo.Context) error {
return c.String(http.StatusOK, "Hello, World!")
})
e.Logger.Fatal(e.Start(":1323"))
}Beego example
package main
import (
"github.com/astaxie/beego"
"github.com/astaxie/beego/orm"
_ "github.com/go-sql-driver/mysql"
)
type User struct {
Id int
Name string
}
func init() {
orm.RegisterDataBase("default", "mysql", "root:password@/test?charset=utf8", 30)
orm.RegisterModel(new(User))
}
func main() {
o := orm.NewOrm()
o.Using("default")
user := User{Name: "testuser"}
id, err := o.Insert(&user)
if err == nil {
fmt.Println(id)
}
}As you can see, each framework has its strengths and weaknesses. You should consider your project’s requirements and choose the framework that best fits your needs.
Next, let’s talk about Golang package managers and dependency managers. Package managers like go get, dep, and go mod help you manage your project’s dependencies. You can use these tools to install, update, and remove packages from your project.
Example
//go get example
$ go get github.com/gin-gonic/gin
// dep example
$ dep ensure
// go mod example
$ go mod init example.com/mymodule
// Glide example
$ glide get github.com/gin-gonic/gin
// Godep example
$ godep get github.com/gin-gonic/gin
// dep example
$ dep ensureDependency managers like Glide, Godep, and dep ensure that your project’s dependencies are consistent and up to date. These tools help you manage your project’s dependencies more effectively, which can save you time and prevent errors.
Finally, let’s talk about some other popular Golang tools and frameworks. If you need to write tests for your Golang code, you might consider using the testing package or a testing framework like Ginkgo.
For logging and monitoring, you might consider using frameworks like Zap or Prometheus.
And if you need to work with databases, you might consider using a package like GORM or a framework like Buffalo.
Ginkgo example
import (
. "github.com/onsi/ginkgo"
. "github.com/onsi/gomega"
)
var _ = Describe("MyModule", func() {
Describe("MyFunction", func() {
It("returns a result", func() {
result := MyFunction()
Expect(result).To(Equal(expectedResult))
})
})
})Zap example
logger, _ := zap.NewProduction()
defer logger.Sync() // flushes buffer, if any
sugar := logger.Sugar()
sugar.Infof("Failed to fetch URL: %s", url)Prometheus example
package main
import (
"net/http"
"github.com/prometheus/client_golang/prometheus/promhttp"
)
func main() {
http.Handle("/metrics", promhttp.Handler())
http.ListenAndServe(":8080", nil)
}GORM example
type User struct {
gorm.Model
Name string
}
func main() {
db, err := gorm.Open("mysql", "user:password@tcp(localhost:3306)/mydb?charset=utf8&parseTime=True&loc=Local")
if err != nil {
panic("failed to connect database")
}
defer db.Close()
// Migrate the schema
db.AutoMigrate(&User{})
// Create
db.Create(&User{Name: "John"})
// Read
var user User
db.First(&user, 1) // find
fmt.Println(user.Name)
// Output: John
// Update
db.Model(&user).Update("Name", "David")
// Delete
db.Delete(&user)
}Buffalo example
package actions
import (
"github.com/gobuffalo/buffalo"
"github.com/gobuffalo/buffalo/render"
)
func HelloHandler(c buffalo.Context) error {
message := "Hello, world!"
return c.Render(200, render.String(message))
}
func init() {
app.GET("/", HelloHandler)
}As you can see, Golang offers a wide range of tools and frameworks that can simplify your development process. By choosing the right framework for your project and using package managers and dependency managers effectively, you can write high-quality code more efficiently.
In summary, Golang tools and frameworks can simplify development by providing useful functionalities out of the box, and package managers and dependency managers can make it easy to manage third-party libraries and dependencies.
When choosing a library or framework for your project, consider its compatibility with your project’s requirements and the level of support and community behind it.
