Go framework architecture is suitable for developing network services (HTTP/RESTful API, WebSockets, RPC services), microservices, CLI tools, data processing applications, and cloud computing applications. Specific use cases include: building a RESTful API using the Gin framework and creating an API gateway using the Traefik framework.
Types of application development that the Go framework architecture is suitable for
Go language is known for its high performance, low latency and concurrency. Its framework ecosystem offers a rich set of tools and libraries that enable developers to build a variety of applications.
Application types suitable for Go framework architecture include:
1. Network service
2. Microservice
3. CLI tools
4. Data processing
5. Cloud computing
Practical case
Build a RESTful API
Create a RESTful API using Go's Gin framework:
package main import ( "github.com/gin-gonic/gin" ) func main() { r := gin.Default() r.GET("/users", getUsers) r.POST("/users", createUser) r.Run() // listen and serve on 0.0.0.0:8080 (for localhost) } func getUsers(c *gin.Context) { // get users from database } func createUser(c *gin.Context) { // create user in database }
Build an API gateway
Create an API gateway using Go's Traefik framework:
package main import ( "github.com/containous/traefik/pkg/provider/kubernetes" ) func main() { // create a Kubernetes provider provider := kubernetes.NewProvider() // configure the Traefik router router := traefik.NewRouter() router.SetProvider(provider) // start the router router.Run("") }
