Create a simple Golang rest api with Mux and MongoDb

golang app in visa sponsor job architect

I will use Mux to create rest api that connect from MongoDb database

In mongodb, I have Default database with AppJobs collection, the api simply get list of job in this collection.

• Firstly we need to install Mux and MongoDb Library

go get -u github.com/gorilla/mux
go get go.mongodb.org/mongo-driver/mongo

• Then create main.go file and init golang app

package main
import “fmt”
func main() {
     fmt.Println(“Starting the application …”)
}

To test golang app, run command go run main.go in your terminal

• Define Job model

• Connect to mongodb

ctx, _ := context.WithTimeout(context.Background(), 10*time.Second)
client, _ = mongo.Connect(ctx, options.Client().ApplyURI(“mongo://localhost:27017”))

• Register router and Endpoint

router := mux.NewRouter()
router.HandleFunc(“/jobs”, getJobPostsEndpoint).Methods(“GET”)
http.ListenAndServe(“:12345”, router)

For this definition, I create “/jobs” endpoint to to get all jobs from mongo db. now we need to create the endpoint and fetch data from mongodb

• Create function to get data from mongodb

• Done, now we can test the api by run command

go run main.go

• Result from this api:

• Full source-code

This api is very simple, I will add more api and refactor in the future when I need to integrate more functions
