+## SurrealDB
+
+GoFr supports injecting SurrealDB database that supports the following interface. Any driver that implements the interface can be added
+using `app.AddSurrealDB()` method, and users can use Surreal DB across application through the `gofr.Context`.
+
+```go
+// SurrealDB defines an interface representing a SurrealDB client with common database operations.
+type SurrealDB interface {
+    // Query executes a Surreal query with the provided variables and returns the query results as a slice of interfaces{}.
+    // It returns an error if the query execution fails.
+    Query(ctx context.Context, query string, vars map[string]any) ([]any, error)
+
+    // Create inserts a new record into the specified table and returns the created record as a map.
+    // It returns an error if the operation fails.
+    Create(ctx context.Context, table string, data any) (map[string]any, error)
+
+    // Update modifies an existing record in the specified table by its ID with the provided data.
+    // It returns the updated record as an interface and an error if the operation fails.
+    Update(ctx context.Context, table string, id string, data any) (any, error)
+
+    // Delete removes a record from the specified table by its ID.
+    // It returns the result of the delete operation as an interface and an error if the operation fails.
+    Delete(ctx context.Context, table string, id string) (any, error)
+
+    // Select retrieves all records from the specified table.
+    // It returns a slice of maps representing the records and an error if the operation fails.
+    Select(ctx context.Context, table string) ([]map[string]any, error)
+
+    HealthChecker
+}
+
+// SurrealDBProvider is an interface that extends SurrealDB with additional methods for logging, metrics, or connection management.
+// It is typically used for initializing and managing SurrealDB-based data sources.
+type SurrealDBProvider interface {
+    SurrealDB
+
+    provider
+}
+```
+Import the gofr's external driver for SurrealDB:
+```shell
+  go get gofr.dev/pkg/gofr/datasource/surrealdb
+```
+The following example demonstrates injecting an SurrealDB instance into a GoFr application.
+
+```go
+package main
+
+import (
+	"gofr.dev/pkg/gofr"
+	"gofr.dev/pkg/gofr/datasource/surrealdb"
+)
+
+type Person struct {
+	ID    string `json:"id,omitempty"`
+	Name  string `json:"name"`
+	Age   int    `json:"age"`
+	Email string `json:"email,omitempty"`
+}
+
+type ErrorResponse struct {
+	Message string `json:"message"`
+}
+
+func main() {
+	app := gofr.New()
+
+	client := surrealdb.New(&surrealdb.Config{
+		Host:       "localhost",

+
+	app.AddSurrealDB(client)
+
+	// GET request to fetch person by ID
+	app.GET("/person/{id}", func(ctx *gofr.Context) (interface{}, error) {
+		id := ctx.PathParam("id")
+
+		query := "SELECT * FROM type::thing('person', $id)"
+		vars := map[string]interface{}{
+			"id": id,
+		}
+
+		result, err := ctx.SurrealDB.Query(ctx, query, vars)
+		if err != nil {
+			return nil, err
+		}
+
+		return result, nil
+	})
+
+	// POST request to create a new person
+	app.POST("/person", func(ctx *gofr.Context) (interface{}, error) {
+		var person Person
+
+		if err := ctx.Bind(&person); err != nil {
+			return ErrorResponse{Message: "Invalid request body"}, nil

+
+		if err != nil {
