The official SurrealDB library for Golang.
For instructions on how to follow SurrealDB, follow Installation Guide
go get github.com/surrealdb/surrealdb.gopackage main
import (
"github.com/surrealdb/surrealdb.go"
)
type User struct {
ID string `json:"id,omitempty"`
Name string `json:"name"`
Surname string `json:"surname"`
}
func main() {
// Connect to SurrealDB
db, err := surrealdb.New("ws://localhost:8000/rpc")

panic(err)
}

// Define user struct

Name: "John",
Surname: "Doe",
}
// Insert user
data, err := db.Create("user", user)

// Unmarshal data

// Unmarshal data

}
// Change part/parts of user
changes := map[string]string{"name": "Jane"}
// Update user
if _, err = db.Update(selectedUser.ID, changes); err != nil {

}
if _, err = db.Query("SELECT * FROM $record", map[string]interface{}{
"record": createdUser[0].ID,
}); err != nil {

}
// Delete user by ID
if _, err = db.Delete(selectedUser.ID); err != nil {

}
}- Step 1: Create a file called
main.goand paste the above code - Step 2: Run the command
go mod init github.com/<github-username>/<project-name>to create a go.mod file - Step 3: Run the command
go mod tidyto download surreal db - Step 4: Run
go run main.goto run the application.

## Building
You can run the Makefile helper to run and build the project
make build
make test
make lint
You also need to be running SurrealDB alongside the tests. We recommend using the nightly build, as development may rely on the latest functionality.
SurrealDB Go library supports smart marshal. It means that you can use any type of data as a value in your struct. SurrealDB Go library will automatically convert it to the correct type.
// Recommended to use with SmartUnmarshal SmartMarshal
// User struct is a test struct
user, err := surrealdb.SmartUnmarshal[testUser](surrealdb.SmartMarshal(s.db.Create, user[0]))
// Can be used without SmartUnmarshal
data, err := surrealdb.SmartMarshal(s.db.Create, user[0])SurrealDB Go library supports smart unmarshal. It means that you can unmarshal any type of data to the generic type provided. SurrealDB Go library will automatically convert it to that type.
// User struct is a test struct
data, err := surrealdb.SmartUnmarshal[testUser](s.db.Select(user[0].ID))
