your MongoDB connection deserves a name: Go edition

An example on how to assign a name to a MongoDB connection in Go.

Get it running

1. Start the MongoDB docker container:

$ docker run --rm \
    --publish 27017:27017 \
    --name ycdan-mongodb \
    --env MONGO_INITDB_ROOT_USERNAME=root \
    --env MONGO_INITDB_ROOT_PASSWORD=secret \
    --detach \
    mongo:5.0.1

1. Compile the example program:

$ go build -o your-connection-deserves-a-name

1. Start the example program:

$ ./your-connection-deserves-a-name

You should see something like

2021/07/30 18:46:37 Connecting to MongoDB on mongodb://root:secret@127.0.0.1:27017/
2021/07/30 18:46:37 Connecting to MongoDB on mongodb://root:secret@127.0.0.1:27017/ ... Successful

2021/07/30 18:46:37 Keeping the connection open ...
2021/07/30 18:46:37 You can connect to the MongoDB server and execute the query:
2021/07/30 18:46:37 	db.currentOp()

1. Login into your mongodb instance and execute the query:

db.currentOp()

In the key appName you can confirm your connection name:

Alternatively, you can also check the server logs:

{
    "t": {
        "$date": "2021-07-30T16:30:18.042+00:00"
    },
    "attr": {
            "application": {
                "name": "currency-conversion-app"
            }
        }
    }
}
