Go implementation of OpenFeature Provider for AWS AppConfig (Feature Flags).
Go 1.22 or higher is required.
We supports latest two major releases of Go.
appName := "app" // Application name of AppConfig
envName := "env" // Environment name of AppConfig
cfgName := "cfg" // Configuration profile name of AppConfig
openfeature.SetProvider(appconfigprovider.New(appName, envName, cfgName))
client := openfeature.NewClient("app")
evalCtx := openfeature.NewTargetlessEvaluationContext(
map[string]any{"userId": "userA"},
)
result, err := client.BooleanValueDetails(ctx, "feature1", false, evalCtx)For more specific usage, please see an example.
Currently, we ONLY support getting flags via AppConfig Agent. If you wish to obtain flags via AWS SDK, please contribute to this project.
This provider ONLY supports getting Boolean values, unless AppConfig Feature Flags supports non-boolean flag values.
The correspondence between data of AppConfig Feature Flags and boolean value details evaluated by the OpenFeature provider is shown in the following table:
| Data of AppConfig Feature Flags | Evaluation Details of OpenFeature |
|---|---|
| feature flag key | flag key |
| enabled value | value (boolean) |
| attributes | flag metadata |
| variant (in multi variant flag) | variant |
| caller context | evaluation context |
