Flipt Go SDK

The Flipt Go SDK supports developing applications in Go against Flipt. It also supports the ability to access the resource management APIs and other systems, such as authentication and metadata.

The SDK supports both Flipts gRPC and HTTP RPC APIs. A majority of this client is generated directly from Flipt's protobuf definitions. The Flipt SDK Generator can be found locally within this repository.

Get the SDK

go get go.flipt.io/flipt/sdk/go

Construct and Authenticate the SDK

Constructing an SDK client is easy.

1. Pick your transport of choice. Bothgrpc or http are sub-packages with respective implementations.
2. Pass a constructed Transport implementation to sdk.New(...).
3. Optionally pass in a sdk.ClientAuthenticationProvider to authenticate your RPC calls.

package main

import (
 sdk "go.flipt.io/flipt/sdk/go"
 sdkgrpc "go.flipt.io/flipt/sdk/go/grpc"
 grpc "google.golang.org/grpc"
)

func main() {
 token := sdk.StaticTokenAuthenticationProvider("a-flipt-client-token")

 conn := grpc.Dial("localhost:9090")
 transport := sdkgrpc.NewTransport(conn)

 client := sdk.New(transport, sdk.WithAuthenticationProvider(token))
}
