How to use Golang with MongoDB

Golang + MongoDB = Powerful. Go is one of the newest programming languages to get a MongoDB driver, and the combination of Go its performance and light, the data-friendly syntax makes MongoDB and Go a fantastic match for building data-driven applications.

Go is one of the newest programming languages to get a MongoDB driver, and the combination of Go its performance and light, the data-friendly syntax makes MongoDB and Go a fantastic match for building data-driven applications.

Getting Started

The first obvious thing you need to do is installing Golang on your device. And either have MongoDB installed locally or use MongoDB Atlas to start cloud-first.

Then you can create a new Go project and install the following module:

go get go.mongodb.org/mongo-driver

To import this module:

package main

import (
   “context”
   “fmt”
   “log”
   “time”
“go.mongodb.org/mongo-driver/bson”
   “go.mongodb.org/mongo-driver/mongo”
   “go.mongodb.org/mongo-driver/mongo/options”
   “go.mongodb.org/mongo-driver/mongo/readpref”
)

Now you can start connecting to your database cluster.

Connect to MongoDB

Here’s an example of connecting to MongoDB in Go:

package main

import (
   “context”
   “fmt”
   “log”
   “time”
“go.mongodb.org/mongo-driver/bson”
   “go.mongodb.org/mongo-driver/mongo”
   “go.mongodb.org/mongo-driver/mongo/options”
   “go.mongodb.org/mongo-driver/mongo/readpref”
)
func main() {
    client, err := mongo.NewClient(options.Client().ApplyURI("mongodb+srv://root:[email protected]/go-test?retryWrites=true&w=majority"))
    if err != nil {
        log.Fatal(err)
    }
    ctx, _ := context.WithTimeout(context.Background(), 10*time.Second)
    err = client.Connect(ctx)
    if err != nil {
            log.Fatal(err)
    }
    defer client.Disconnect(ctx)
    }

If you’re using MongoDB Atlas, make sure that you’ve white-listed your development IP address, and find the connection string in the Atlas console. Once you’re connected, the MongoDB Golang driver has everything you need to query, modify, and work with document data in your Go application.
