To run migrations using pgx in Go, you'll typically follow a series of steps that involve setting up your PostgreSQL database connection, creating migration files, and applying those migrations programmatically. Below is an example of how to structure your migration script using the pgx library.
// Import necessary packages
package main
import (
"context"
"github.com/jackc/pgx/v4"
"log"
"os"
)
func main() {
// Connect to the PostgreSQL database
conn, err := pgx.Connect(context.Background(), os.Getenv("DATABASE_URL"))
if err != nil {
log.Fatal(err)
}
defer conn.Close(context.Background())
// Define your migrations
migrations := []string{
`CREATE TABLE IF NOT EXISTS users (
id SERIAL PRIMARY KEY,
name TEXT,
email TEXT UNIQUE
);`,
// Add more migrations as needed
}
// Execute the migrations
for _, migration := range migrations {
_, err := conn.Exec(context.Background(), migration)
if err != nil {
log.Fatalf("Failed to execute migration: %v", err)
}
}
log.Println("Migrations applied successfully!")
}
