What are the learning paths in the golang framework community?

The ways for beginners to learn the Golang community framework are: read official documents and tutorials to understand the basic information of the framework. Follow the official blog and community blog to get experience and best practices in using the framework. Read books to gain a deeper understanding of the framework's features and distributed applications. Refer to practical cases to master the use of frameworks to build web applications and microservices.

Golang Community Framework Learning Path

Golang is a modern programming language launched by Google. Its lightweight, high performance and concurrency characteristics make it Become an ideal choice for cloud native development. The Golang ecosystem is rich in community frameworks that simplify the development process and provide powerful functionality.

1. Documentation and tutorials

• Golang official documentation: Official documentation is the authoritative source for understanding the Golang framework, providing detailed API documentation and tutorials.
• Framework documentation: Each community framework provides its own documentation describing its features, installation, and usage. A deep dive into these documents is critical to understanding how the framework works.

2. Blogs and articles

• Official Golang Blog: Google regularly publishes blog posts covering the latest frameworks and tools in the Golang ecosystem.
• Community blog: The active Golang community has many blogs that provide experience, examples and best practices in using the framework.

3. Books

• "Go Web Framework: Using Go to Build Web Applications":A book that specifically introduces the Golang Web Framework, in-depth Introducing various popular frameworks.
• "Go Programming Language: Distributed Network Programming": A comprehensive book covering Golang distributed programming topics, including the application of the framework in distributed systems.

4. Practical Cases

Case: Use Gin Gonic to build REST API

package main

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

func main() {
    router := gin.Default()

    router.GET("/users", func(c *gin.Context) {
        c.JSON(200, gin.H{"message": "Hello, World!"})
    })

    router.Run()
}

Case: Use gRPC to build microservices

package main

import (
    "context"
    "log"

    pb "github.com/myrepo/product/api"
    "google.golang.org/grpc"
)

func main() {
    conn, err := grpc.Dial("localhost:50051", grpc.WithInsecure())
    if err != nil {
        log.Fatalf("could not connect: %v", err)
    }
    defer conn.Close()

    client := pb.NewProductClient(conn)
    req := &pb.GetProductRequest{Id: "product-id"}
    resp, err := client.GetProduct(context.Background(), req)
    if err != nil {
        log.Fatalf("could not get product: %v", err)
    }

    log.Printf("Product: %s", resp.Name)
}
