Creating your first document in MongoDB

In this recipe, we will learn how we can create a BSON document (a binary-encoded serialization of JSON-like documents) in a database, using a MongoDB driver for Go (gopkg.in/mgo.v2). 

How to do it…

1. Install the gopkg.in/mgo.v2 and github.com/gorilla/mux packages, using the go get command, as follows:

$ go get gopkg.in/mgo.v2
$ go get github.com/gorilla/mux

2. Create create-record-mongodb.go. Then we connect to the MongoDB database, create an employee document with two fields—ID and name—and write the last created document ID to an HTTP response stream, as follows:

package main
import 
(
  "fmt"
  "log"
  "net/http"
  "strconv"
  "github.com/gorilla/mux"
  mgo "gopkg.in/mgo.v2"
)
const 
(
  CONN_HOST = "localhost"
  CONN_PORT = "8080"
  MONGO_DB_URL = "127.0.0.1"
)
var session *mgo.Session
var connectionError error
type Employee struct 
{
  Id int `json:"uid"`
  Name string `json:"name"`
}
func init() 
{
  session, connectionError = mgo.Dial(MONGO_DB_URL)
...
