Optimizely Go SDK

Usage

Instantiation

To start using the SDK, create an instance using our factory method:

import "github.com/optimizely/go-sdk/pkg/client"

optimizelyFactory := &client.OptimizelyFactory{
  SDKKey: "[SDK_KEY_HERE]",
}

client, err := optimizelyFactory.Client()

// You can also instantiate with a hard-coded datafile
optimizelyFactory := &client.OptimizelyFactory{
	Datafile: []byte("datafile_string"),
}

client, err := optimizelyFactory.Client()

Feature Rollouts

import (
  "github.com/optimizely/go-sdk/pkg/client"
  "github.com/optimizely/go-sdk/pkg/entities"
)

user := entities.UserContext{
  ID: "optimizely end user",
  Attributes: map[string]interface{}{
    "state":      "California",
    "likes_donuts": true,
  },
}

enabled, _ := client.IsFeatureEnabled("binary_feature", user)

Command line interface

A CLI has been provided to illustrate the functionality of the SDK. Simply run go-sdk for help.

go-sdk provides cli access to your Optimizely fullstack project

Usage:
  go-sdk [command]

Available Commands:
  help                          Help about any command
  is_feature_enabled            Is feature enabled?
  get_enabled_features          Get enabled features
  track                         Track a conversion event
  get_feature_variable_boolean  Get feature variable boolean value
  get_feature_variable_double   Get feature variable double value
  get_feature_variable_integer  Get feature variable integer value
  get_feature_variable_string   Get feature variable string value

Flags:
  -h, --help            help for go-sdk
  -s, --sdkKey string   Optimizely project SDK key

Use "go-sdk [command] --help" for more information about a command.

Each supported SDK API method is it's own cobra command and requires the input of an --sdkKey.

Installation

Install the CLI from github:

go install github.com/optimizely/go-sdk

Install the CLI from source:

go get github.com/optimizely/go-sdk
cd $GOPATH/src/github.com/optimizely/go-sdk
go install

NOTE: We practice trunk-based development, and as such our default branch, master might not always be the most stable. We do tag releases on Github and you can pin your installation to those particular release versions. One way to do this is to use Go Modules for managing external dependencies:

module mymodule

go 1.12

require (
	github.com/optimizely/go-sdk v1.0.0-beta2
)

If you are already using go.mod in your application you can run the following:

go mod edit -require github.com/optimizely/go-sdk@v1.0.0-beta2

NOTE:

go get github.com/optimizely/go-sdk/...

or

go get github.com/optimizely/go-sdk/pkg

will install it as a package to pkg directory, rather than src directory. It could be useful for future development and vendoring.
