Go ObjectBox Database API

ObjectBox is a superfast Go database persisting objects; check the performance benchmarks vs SQLite (GORM) & Storm. Using this Golang API, you can use ObjectBox as an embedded database in your Go application.

Your opinion matters to us! Please fill in this 2-minute Anonymous Feedback Form.

ObjectBox persists your native Go structs using a simple CRUD API:

id, err := box.Put(&Person{ FirstName: "Joe", LastName:  "Green" })

Latest release: v1.6.1 (2022-01-27)

High-performance Golang database

🏁 High performance on restricted devices, like IoT gateways, micro controllers, ECUs etc.
🪂 Resourceful with minimal CPU, power and Memory usage for maximum flexibility and sustainability
🔗 Relations: object links / relationships are built-in
💻 Multiplatform: Linux, Windows, Android, iOS, macOS

🌱 Scalable: handling millions of objects resource-efficiently with ease
💐 Queries: filter data as needed, even across relations
🦮 Statically typed: compile time checks & optimizations
📃 Automatic schema migrations: no update scripts needed

And much more than just data persistence
👥 ObjectBox Sync: keeps data in sync between devices and servers
🕒 ObjectBox TS: time series extension for time based data

Enjoy ❤️

Getting started

To install ObjectBox, execute the following command in your project directory. You can have a look at installation docs for more details and further instructions.

bash <(curl -s https://raw.githubusercontent.com/objectbox/objectbox-go/main/install.sh)

To install ObjectBox Sync variant of the library, pass --sync argument to the command above:

bash <(curl -s https://raw.githubusercontent.com/objectbox/objectbox-go/main/install.sh) --sync

You can run tests to validate your installation

go test github.com/objectbox/objectbox-go/...

With the dependencies installed, you can start adding entities to your project:

//go:generate go run github.com/objectbox/objectbox-go/cmd/objectbox-gogen
​
type Task struct {
	Id   uint64
	Text string
}

And run code generation in your project dir

go generate ./...

This generates a few files in the same folder as the entity - remember to add those to version control (e. g. git).

Once code generation finished successfully, you can start using ObjectBox:

obx := objectbox.NewBuilder().Model(ObjectBoxModel()).Build()
box := BoxForTask(obx) // Generated function to provide a Box for Task objects
id, _ := box.Put(&Task{ Text: "Buy milk" })

See the Getting started section of our docs for a more thorough intro.

Also, please have a look at the examples directory and for the API reference see ObjectBox GoDocs - and the sources in this repo.

Upgrading to a newer version

When you want to update, please re-run the entire installation process to ensure all components are updated:

• ObjectBox itself (objectbox/objectbox-go)
• Dependencies (flatbuffers)
• ObjectBox library (libobjectbox.so|dylib; objectbox.dll)
• ObjectBox code generator

This is important as diverging versions of any component might result in errors.

The install.sh script can also be used for upgrading:

bash <(curl -s https://raw.githubusercontent.com/objectbox/objectbox-go/main/install.sh)

Afterwards, don't forget to re-run the code generation on your project

go generate ./...

Other languages/bindings

ObjectBox supports multiple platforms and languages:

• ObjectBox Java/Kotlin: runs on Android, desktop, and servers
• ObjectBox Swift: build fast mobile apps for iOS (and macOS)
• ObjectBox Dart/Flutter: cross-platform for mobile and desktop apps
• ObjectBox C and C++: native speed with zero copy access to FlatBuffer objects
