AWS AppConfig Agent Client for Go

Go client for AWS AppConfig Agent.

Requirements

Go 1.22 or higher is required. We support latest two major releases of Go.

Currently, the major version of AppConfig Agent must be v2.

Usage

Create a client

app := "app" // Application name or ID of AppConfig
env := "env" // Environment name or ID of AppConfig
client := appconfigagentv2.NewClient(app, env)

Get configuration data

ctx := context.Background()
cfg := "cfg" // Configuration name or ID of AppConfig
res, err := client.GetConfiguration(ctx, cfg)
if err != nil {
    log.Fatal(err)
}
data, err := io.ReadAll(res.ConfigurationBody)

Evaluate a flag in feature flag configuration

This is only available for configurations of feature flags type.

ctx := context.Background()
cfg := "cfg" // Configuration name or ID of AppConfig
flag := "feature1" // Flag key of AppConfig feature flags
res, err := client.EvaluateFeatureFlag(ctx, cfg, flag, nil)

You can also pass evaluation contexts for multi-variant flags:

ctx := context.Background()
cfg := "cfg" // Configuration name or ID of AppConfig
flag := "feature1" // Flag key of AppConfig feature flags
evalCtx := map[string]any{"orgID": "awesomeOrg", "userID": 123}
res, err := client.EvaluateFeatureFlag(ctx, cfg, flag, evalCtx)

Evaluate multiple flags in feature flag configuration

This is only available for configurations of feature flags type.

ctx := context.Background()
cfg := "cfg" // Configuration name or ID of AppConfig
flag1 := "feature1" // Flag key of AppConfig feature flags
flag2 := "feature2"
res, err := client.BulkEvaluateFeatureFlag(ctx, cfg, []string{flag1, flag2}, nil)
if err != nil {
    log.Fatal(err)
}
flag1res, ok := res.Evaluations[flag1]
flag2res, ok := res.Evaluations[flag2]
