How to build enterprise applications with Go: Build a scalable microservices architecture: define microservices, listen on ports and handle requests. Follow best practices: use concurrency, ensure memory safety, write testable code, adopt structure and interfaces, use dependency management, adopt logging and monitoring, consider distributed system patterns, follow coding style guidelines.
Go is a powerful programming language ideal for building large-scale distributed applications . It provides a range of features such as concurrency, memory safety, and garbage collection, making it ideal for building enterprise-level systems.
The following is an example of how to use Go to build a scalable microservice architecture:
// 定义一个微服务 type Service struct { Name string Port int } // 主函数 func main() { // 创建一个新的服务实例 service := Service{Name: "my-service", Port: 8080} // 启动服务 service.Start() } // 启动服务 func (s *Service) Start() { // 监听端口 ln, err := net.Listen("tcp", fmt.Sprintf(":%d", s.Port)) if err != nil { log.Fatal(err) } // 接受连接并处理请求 for { conn, err := ln.Accept() if err != nil { log.Println(err) continue } go func() { // 处理连接 defer conn.Close() // 读取请求 req, err := http.ReadRequest(conn) if err != nil { log.Println(err) return } // 写入响应 resp := http.Response{ StatusCode: http.StatusOK, Body: ioutil.NopCloser(strings.NewReader("Hello, world!")), } if err := req.Write(resp); err != nil { log.Println(err) } }() } }
When building enterprise-grade Go applications, follow these best practices:
