- First check the Go version by running the command
go version
- Create a folder
mkdir <folder_name>
- Switch to created folder
cd <folder_name>
- Initialize the go project by running the given command. You will get
go.modfile.
go mod init <folder_name>
- Create a
main.gofile, use terminal or bash
notepad main.go
touch main.go
- Let's write some basic code in
main.gofile.
package main
import (
"fmt"
)
func main() {
fmt.Println("MongoDb with Go")
}
- Run the code by following command
go run main.go
- You will see this output in console
MongoDb with Go
- 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
- Revisit the
main.gofile 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")
}
- Run the code by following command again
go run main.go
- You will see this output in console
Connected to MongoDB!
MongoDb with Go
