Couchbase Ruby Client

This repository contains the third generation of the official Couchbase SDK for Ruby (aka. SDKv3)

Support and Feedback

If you find an issue, please file it in our JIRA issue tracker. Also you are always welcome on our forum.

Please attach version information to ticket/post. To obtain this information use the following command:

$ ruby -r couchbase -e 'p Couchbase::VERSION'


The library tested with the MRI 2.5, 2.6 and 2.7. Supported platforms are Linux and MacOS.

Add this line to your application's Gemfile:

# version (does not have precompiled binarie)
gem "couchbase", "3.0.0.beta.1"

# source version from official repository
gem "couchbase", "3.0.0.beta.1", :source => ""

## precompiled binaries (uncomment line with effective ABI version of ruby)
# gem "couchbase", "3.0.0.beta.1", :platforms => :mri_27, :source => ""
# gem "couchbase", "3.0.0.beta.1", :platforms => :mri_26, :source => ""
# gem "couchbase", "3.0.0.beta.1", :platforms => :mri_25, :source => ""

And then execute:

$ bundle install

Or install it yourself as:

$ gem install --pre couchbase

For some platforms we precompile binary packages. When, for some reason, binary package cannot be used, pass --platform=ruby to gem install command (or check specific_platform and force_ruby_platform options of Bundler). In latter case, see Development section for build dependencies.


After checking out the repo, run bin/setup to install dependencies. You can also run bin/console for an interactive prompt that will allow you to experiment.

Part of the library is written in C++, and requires both C and C++ compilers installed on the system. To configure build environment, it uses cmake. When these tools installed, the build process is easy:

$ rake compile

Generate Documentation

To generate documentation yard library is highly recommended.

$ gem install yard

The following steps will generate API reference for selected git tag:

$ rake doc

Now the API reference is accessible using web browser (where VERSION is current version of the SDK)

$ firefox doc/couchbase-ruby-client-VERSION/index.html
