ObjectBox Go Database - simple but powerful; frugal but fast
The Golang database is easy to use via an intuitive native Golang API and persists objects superfast and sustainably.
Go and check out the performance benchmarks vs SQLite (GORM) & Storm.
ObjectBox persists your native Go structs using a simple CRUD API:
id, err := box.Put(&Person{ FirstName: "Joe", LastName: "Green" })

High-performance Go database
๐ High performance on restricted devices, like IoT gateways, micro controllers, ECUs etc.
๐ Resourceful with minimal CPU, power and Memory usage for maximum flexibility and sustainability
๐ Relations: object links / relationships are built-in
๐ป Multiplatform: Linux, Windows, Android, iOS, macOS
๐ฑ Scalable: handling millions of objects resource-efficiently with ease
๐ Queries: filter data as needed, even across relations
๐ฆฎ Statically typed: compile time checks & optimizations
๐ Automatic schema migrations: no update scripts needed
And much more than just data persistence
๐ฅ ObjectBox Sync: keeps data in sync between devices and servers
๐ ObjectBox TS: time series extension for time based data
Getting started: Go!
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
โ
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:
- Java/Kotlin Database: runs on Android, desktop, and servers
- Swift Database: build fast mobile apps for iOS (and macOS)
- Dart/Flutter Database: cross-platform for mobile and desktop apps
- C and C++ Database: native speed with zero copy access to FlatBuffer objects
