    "fmt"
    "log"
    
    "github.com/macrox-pro/go-directus-sdk"
)

type User struct {

func main() {
    // Create a client with static token
    client, err := directus.NewClient(
        "https://your-directus-instance.com",
        directus.WithStaticToken("your-access-token"),
    )
    if err != nil {
        log.Fatal(err)
    }
    
    // Read items (without filtering)
    ctx := context.Background()
    users, err := directus.NewReadItems[User]("users").
        SetLimit(10).
        SetOffset(0).
        SendBy(client)
    if err != nil {
        log.Fatal(err)
    }
    
    for _, user := range users {
        fmt.Printf("User: %s (%s)\n", user.Name, user.Email)
    }
}

client, err := directus.NewClient(
    "https://api.example.com",
    directus.WithStaticToken("your-access-token"),
)

Context-Based Token

    "https://api.example.com",
    directus.WithExtractTokenFromContext(true),
)

ctx := directus.WithAccessTokenContext(context.Background(), "dynamic-token")
// Use ctx in requests

Login with Credentials

resp, err := client.AuthLogin(ctx, directus.AuthLoginParams{
    Email:    "admin@example.com",

}

CRUD Operations

Create Item

newUser := User{Name: "John Doe", Email: "john@example.com"}
created, err := directus.NewCreateItem[User]("users", newUser).
    SendBy(client)

Read Item

user, err := directus.NewReadItem[User]("users", "user-123").
    SendBy(client)

Read Items with Filtering

// Create a filter using ByField and Equal
filter := directus.ByField{
    Name: "status",
    Filter: directus.Equal[string]{Value: "active"},
}
users, err := directus.NewReadItems[User]("users").
    SetFilter(filter).
    SetSort("-created_at").
    SetLimit(100).
    SetOffset(0).
    SendBy(client)

Update Item

updated, err := directus.NewUpdateItem[User]("users", "user-123").
    SetChanges(map[string]any{"name": "John Updated"}).
    SendBy(client)

Update Items (Batch)

err := directus.NewUpdateItems[User]("users").
    SetFilter(directus.ByField{
        Name: "status",
        Filter: directus.Equal[string]{Value: "inactive"},
    }).
    SetChanges(map[string]any{"archived": true}).
    SendBy(client)

Delete Item

err := directus.NewDeleteItem("users", "user-123").
    SendBy(client)

Delete Items (Batch)

err := directus.NewDeleteItems[string]("users").
    SetFilter(directus.ByField{
        Name: "status",
        Filter: directus.Equal[string]{Value: "deleted"},
    }).
    SendBy(client)

Filtering

The SDK provides type-safe filter rules via structs. You can compose filters using the ByField wrapper.

Basic comparisons

// Equal
filter := directus.ByField{
    Name: "status",
    Filter: directus.Equal[string]{Value: "active"},
}

// Not equal
filter := directus.ByField{
    Name: "status",
    Filter: directus.NotEqual[string]{Value: "inactive"},
}

// Greater than
filter := directus.ByField{
    Name: "age",
    Filter: directus.GreaterThan[int]{Value: 18},
}

// Less than
filter := directus.ByField{
    Name: "price",
    Filter: directus.LessThan[float64]{Value: 100.0},
}

String operations

// Contains
filter := directus.ByField{
    Name: "title",
    Filter: directus.Contains{Value: "important"},
}

// Starts with
filter := directus.ByField{
    Name: "email",
    Filter: directus.StartsWith{Value: "admin@"},
}

// Ends with
filter := directus.ByField{
    Name: "filename",
    Filter: directus.EndsWith{Value: ".pdf"},
}

Logical operators

// AND
filter := directus.AND{
    Filters: []directus.FilterRule{
        directus.ByField{Name: "status", Filter: directus.Equal[string]{Value: "active"}},
        directus.ByField{Name: "age", Filter: directus.GreaterThan[int]{Value: 18}},
    },
}

// OR
filter := directus.OR{
    Filters: []directus.FilterRule{
        directus.ByField{Name: "role", Filter: directus.Equal[string]{Value: "admin"}},
        directus.ByField{Name: "role", Filter: directus.Equal[string]{Value: "moderator"}},
    },
}

// NOT
filter := directus.NOT{
    Filter: directus.ByField{Name: "status", Filter: directus.Equal[string]{Value: "deleted"}},
}

Null checks

filter := directus.ByField{
    Name: "deleted_at",
    Filter: directus.IsNull{},
}

filter := directus.ByField{
    Name: "updated_at",
    Filter: directus.IsNotNull{},
}

In / NotIn

filter := directus.ByField{
    Name: "category",
    Filter: directus.In[string]{Values: []string{"news", "blog", "tutorial"}},
}

filter := directus.ByField{
    Name: "status",
    Filter: directus.NotIn[string]{Values: []string{"draft", "archived"}},
}

Between

filter := directus.ByField{
    Name: "price",
    Filter: directus.Between[float64]{Low: 10.0, High: 100.0},
}

Aggregation

Aggregation is performed using directus.NewAggregate and SetAggregate with an aggregate rule.

Count

result, err := directus.NewAggregate[any]("users").
    SetAggregate(directus.Count{}).
    SetFilter(directus.ByField{
        Name: "status",
        Filter: directus.Equal[string]{Value: "active"},
    }).
    SendBy(client)

Sum

result, err := directus.NewAggregate[any]("orders").
    SetAggregate(directus.Sum{Fields: []string{"total_amount"}}).
    SetFilter(directus.ByField{
        Name: "status",
        Filter: directus.Equal[string]{Value: "completed"},
    }).
    SendBy(client)

Multiple aggregations

result, err := directus.NewAggregate[any]("products").
    SetAggregate(directus.Many{
        Rules: []directus.AggregateRule{
            directus.Count{},
            directus.Sum{Fields: []string{"stock"}},
            directus.Avg{Fields: []string{"price"}},
            directus.Min{Fields: []string{"price"}},
            directus.Max{Fields: []string{"price"}},
        },
    }).
    SendBy(client)

Note: Use directus.Many to combine multiple aggregate rules in a single request.

Server Information

Ping

ping, err := client.ServerPing(ctx)

Health

health, err := client.ServerHealth(ctx)

Info

info, err := client.ServerInfo(ctx)

Singleton Operations

Read Singleton

settings, err := directus.NewReadSingleton[Settings]("settings").
    SendBy(client)

Update Singleton

Update of singletons is currently not implemented as a separate method. Use UpdateItem with the singleton collection name.

Error Handling

The SDK returns structured errors:

items, err := directus.NewReadItems[User]("users").SendBy(client)
if err != nil {
    if errs, ok := err.(directus.Errors); ok {
        for _, e := range errs {
            fmt.Printf("Error %d: %s\n", e.Status(), e.Message)
        }
    } else {
        log.Fatal(err)
    }
}

Advanced Usage

Deep Query

users, err := directus.NewReadItems[User]("users").
    SetDeep(map[string]directus.DeepQuery{
        "posts": {
            Filter: directus.ByField{
                Name: "status",
                Filter: directus.Equal[string]{Value: "published"},
            },
            Limit: 5,
        },
    }).
    SendBy(client)

System Collections

// Access Directus system collections
roles, err := directus.NewReadItems[Role]("directus_roles").
    SetIsSystem(true).
    SendBy(client)

Configuration

Client Options

client, err := directus.NewClient(
    "https://api.example.com",
    directus.WithStaticToken("your-access-token"),
    directus.WithExtractTokenFromContext(true),
)

Custom HTTP Client

The SDK uses github.com/go-resty/resty/v2 internally. You can customize the underlying HTTP client by accessing the resty client directly:

// Create client first
client, err := directus.NewClient("https://api.example.com")
if err != nil {
    log.Fatal(err)
}

// Access the underlying resty client
restyClient := client.resty // Note: field is not exported, you need to use reflection or provide a getter.
// Currently there is no public method to access the resty client.
