How to Use ent (Facebook's ORM) for Go Database Access

Use ent by defining your schema in Go structs, generating the code with entc, and then using the generated client to query your database.

// 1. Define schema in schema/user.go
type User struct {
    ent.Schema
}

func (User) Fields() []ent.Field {
    return []ent.Field{
        field.String("name"),
    }
}

// 2. Generate code: entc generate
// 3. Use in main.go
client, _ := ent.Open("sqlite3", "file:ent?mode=memory")
user, _ := client.User.Create().SetName("Alice").Save(ctx)
_ = user.Name

Ent is a tool that turns your Go data structures into a full database layer automatically. Instead of writing repetitive SQL queries by hand, you define your data model once, and Ent generates the safe, efficient code needed to save and load it. Think of it as a blueprint generator that builds the plumbing between your application and your database so you don't have to.
