ObjectBox Go API

ObjectBox is a superfast database for objects. Using this Golang API, you can us ObjectBox as an embedded database in your Go application. In this embedded mode, it runs within your application process.

Some features

  • Object storage: put and get native Go structs
  • Secondary indexes based on object properties
  • Simple CRUD API
  • Asynchronous puts
  • Automatic model migration (no schema upgrade scripts etc.)
  • (Coming soon: Powerful queries)
  • (Coming soon: Relations to other objects)

Installation

To get started with ObjectBox you can get the repository code as usual with go get and install the two prerequisites - pre-compiled library and a bindings generator.

go get github.com/objectbox/objectbox-go
go get github.com/google/flatbuffers/go
go install github.com/objectbox/objectbox-go/cmd/objectbox-gogen/

mkdir objectboxlib && cd objectboxlib
curl https://raw.githubusercontent.com/objectbox/objectbox-c/master/download.sh > download.sh
bash download.sh

See installation docs for more details and further instructions.

Additionally, you can run tests to validate your installation

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

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)
  • libobjectbox
  • ObjectBox code generator

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

This repository also come with a install.sh script that can be used for installation and upgrading:

~/go/src/github.com/objectbox/objectbox-go/install.sh

Docs

Documentation is still on-going work. To get started, please have a look at the examples directory and golang.objectbox.io.

Current state

As this is still an early version of the Go APIs, they are not as convenient as the Java/Kotlin APIs, which deeply integrate into the language using e.g. @Entity annotations.

A better language integration could be build based on reflection, code generation, or a combination of both.
