#go #mongodb #webdev
  • First check the Go version by running the command 
go version
Enter fullscreen mode Exit fullscreen mode
  • Create a folder 
mkdir <folder_name>
Enter fullscreen mode Exit fullscreen mode
  • Switch to created folder 
cd <folder_name>
Enter fullscreen mode Exit fullscreen mode
  • Initialize the go project by running the given command. You will get go.mod file. 
go mod init <folder_name>
Enter fullscreen mode Exit fullscreen mode
  • Create a main.go file, use terminal or bash 
notepad main.go touch main.go
Enter fullscreen mode Exit fullscreen mode
  • Let's write some basic code in main.go file. 
package main import ( "fmt" ) func main() { fmt.Println("MongoDb with Go") }
Enter fullscreen mode Exit fullscreen mode
  • Run the code by following command 
go run main.go
Enter fullscreen mode Exit fullscreen mode
  • You will see this output in console 
MongoDb with Go
Enter fullscreen mode Exit fullscreen mode
  • Install some packages to connect MongoDB in Go. Here are commands 
go get go.mongodb.org/mongo-driver go get go.mongodb.org/mongo-driver/mongo
Enter fullscreen mode Exit fullscreen mode
  • Revisit the main.go file to connect MongoDB. This is our full code 
package main import ( "context" "fmt" "log" "go.mongodb.org/mongo-driver/mongo" "go.mongodb.org/mongo-driver/mongo/options" ) // mongodb connections var collection *mongo.Collection var ctx = context.TODO() func init() { clientOptions := options.Client().ApplyURI("mongodb://localhost:27017/") client, err := mongo.Connect(ctx, clientOptions) if err != nil { log.Fatal(err) } // check connection err = client.Ping(ctx, nil) if err != nil { log.Fatal(err) } fmt.Println("Connected to MongoDB!") collection = client.Database("testingWithGo").Collection("movies") } func main() { fmt.Println("MongoDb with Go") }
Enter fullscreen mode Exit fullscreen mode
  • Run the code by following command again 
go run main.go
Enter fullscreen mode Exit fullscreen mode
  • You will see this output in console 
Connected to MongoDB! MongoDb with Go
Enter fullscreen mode Exit fullscreen mode

That's for today. Thank You .
