Trouble getting started with Open Feature Go provider

Open Source
1

I’m trying to get started with openfeature go provider but running into some issues, its possible there is something wrong with my environment. When I run

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

and then go mod tidy

I see this error:

go: finding module for package github.com/open-feature/go-sdk-contrib/providers/flipt
go: snippetbox.levlaz.org/cmd/web imports
        github.com/open-feature/go-sdk-contrib/providers/flipt: module github.com/open-feature/go-sdk-contrib/providers/flipt@latest found (v0.1.1), but does not contain package github.com/open-feature/go-sdk-contrib/providers/flipt

Any ideas?

So the problem is that the actual provider is nested within this module in /pkg/provider. So you have to do the following import to get it:

package main

import (
	"context"

	flipt "github.com/open-feature/go-sdk-contrib/providers/flipt/pkg/provider"
	"github.com/open-feature/go-sdk/openfeature"
)

func main() {
	// http://localhost:8080 is the default Flipt address
	openfeature.SetProvider(flipt.NewProvider())

	client := openfeature.NewClient("my-app")
	value, err := client.BooleanValue(context.Background(), "v2_enabled", false, openfeature.NewEvaluationContext(
		"tim@apple.com",
		map[string]interface{}{
			"favorite_color": "blue",
		},
	))

	if err != nil {
		panic(err)
	}

	if value {
		// do something
	} else {
		// do something else
	}
}

I just popped open a PR to address this chore(providers/flipt): update README with correct provider import statement by GeorgeMac · Pull Request #496 · open-feature/go-sdk-contrib · GitHub
