Go

Verified against provider v0.1.7 and go-sdk v1.18.0.

Install

go get github.com/open-feature/go-sdk-contrib/providers/ofrep
go get github.com/open-feature/go-sdk/openfeature

The import path is the module root, .../providers/ofrep, not a /pkg subpackage.

Read a flag

package main

import (
  "context"

  "github.com/open-feature/go-sdk-contrib/providers/ofrep"
  "github.com/open-feature/go-sdk/openfeature"
)

func main() {
  provider := ofrep.NewProvider(
    "https://flags.example.com",
    ofrep.WithApiKeyAuth("your-read-api-key"),
  )
  if err := openfeature.SetProviderAndWait(provider); err != nil {
    panic(err)
  }

  client := openfeature.NewClient("my-app")
  evalCtx := openfeature.NewEvaluationContext("user-123", map[string]interface{}{
    "plan": "pro",
  })

  enabled, _ := client.BooleanValue(context.Background(), "new-checkout", false, evalCtx)
  if enabled {
    // serve the new checkout
  }
}

WithApiKeyAuth attaches the x-api-key header. If the key is wrong, BooleanValue returns the default you passed (false here), never the real flag value.
