If you do not have one already, create a Neon project. Save your connection details including your password. They are required when defining connection settings.

To create a Neon project:

1. Navigate to the Projects page in the Neon Console.
2. Click New Project.
3. Specify your project settings and click Create Project.

Configure Go application connection settings

Connecting to Neon requires configuring connection settings in your Go project's .go file.

Specify the connection settings in your .go file, as shown in the following example:

package main

import (
    "database/sql"
    "fmt"

    _ "github.com/lib/pq"
)

func main() {
    connStr := "postgres://[user]:[password]@[neon_hostname]/[dbname]?sslmode=require"
    db, err := sql.Open("postgres", connStr)
    if err != nil {
        panic(err)
    }
    defer db.Close()
    
    var version string
    if err := db.QueryRow("select version()").Scan(&version); err != nil {
        panic(err)
    }

    fmt.Printf("version=%s\n", version)
}

You can find all of the connection details listed above in the Connection Details widget on the Neon Dashboard. For more information, see Connect from any application.
