Description
ObjectBox is a superfast database for objects. Using this Golang API, you can use ObjectBox as an embedded database in your Go application. A client/server mode will follow soon.
ObjectBox persists your native Go structs using a simple CRUD API:
id, err := box.Put(&Person{ FirstName: "Joe", LastName: "Green" })

ObjectBox Go API
ObjectBox is a superfast database for objects. Using this Golang API, you can use ObjectBox as an embedded database in your Go application. A client/server mode will follow soon.
ObjectBox persists your native Go structs using a simple CRUD API:
id, err := box.Put(&Person{ FirstName: "Joe", LastName: "Green" })
Want details? Read the docs or check out the API reference.
Latest release: v1.2.0 (2020-08-25)
Some features
- Powerful queries
- Relations (to-one, to-many)
- Secondary indexes based on object properties
- Asynchronous puts
- Automatic model migration (no schema upgrade scripts etc.)
- inline/prefix complex embedded structs (or you can use custom converters)
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/master/install.sh)
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](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/master/install.sh)
Afterwards, don't forget to re-run the code generation on your project
go generate ./...
