Before you Begin

Harness Feature Flags (FF) is a feature management solution that enables users to change the software’s functionality, without deploying new code. FF uses feature flags to hide code or behaviours without having to ship new versions of the software. A feature flag is like a powerful if statement.

go get github.com/harness/ff-golang-server-sdk

Usage

First we need to import lib with harness alias

import harness "github.com/harness/ff-golang-server-sdk/client"

Next we create client instance for interaction with api

client, err := harness.NewCfClient(sdkKey)

Target definition can be user, device, app etc.

target := dto.NewTargetBuilder("key").
 		Firstname("John").
 		Lastname("doe").
 		Email("johndoe@acme.com").
 		Country("USA").
 		Custom("height", 160).
 		Build()

Evaluating Feature Flag

showFeature, err := client.BoolVariation(featureFlagKey, &target, false)

Flush any changes and close the SDK

client.close()
