Functions

func GetReadyChannel

func GetReadyChannel() chan bool

GetReadyChannel returns a channel which will notify when the server is ready

func GetServerPort

func GetServerPort() (int, error)

GetServerPort returns the actual port used by the REST API

func RunServer

func RunServer(ctx context.Context, grpcPort int, httpPort int, serverOpts ...ServerConfigOption) (err error)

RunServer starts our REST API. The REST API is a reverse proxy using grpc-gateway that exposes certain gRPC calls as RESTful HTTP methods.

func StopServer

func StopServer(ctx context.Context)

StopServer is in charge of stopping the REST API.

Types

type ServerConfigOption

type ServerConfigOption func(*corsConfig, *runtime.ServeMux)

ServerConfigOption represents functional-style options to modify the server configuration in RunServer.

func WithAdditionalHandler

func WithAdditionalHandler(method string, path string, h runtime.HandlerFunc) ServerConfigOption

WithAdditionalHandler is an option to add an additional handler func in the REST server.

func WithAllowedHeaders

func WithAllowedHeaders(headers []string) ServerConfigOption

WithAllowedHeaders is an option to supply allowed headers in CORS.

func WithAllowedMethods

func WithAllowedMethods(methods []string) ServerConfigOption

WithAllowedMethods is an option to supply allowed methods in CORS.

func WithAllowedOrigins

func WithAllowedOrigins(origins []string) ServerConfigOption

WithAllowedOrigins is an option to supply allowed origins in CORS.

func WithEmbeddedOAuth2Server

func WithEmbeddedOAuth2Server(keyPath string, keyPassword string, saveOnCreate bool, opts ...oauth2.AuthorizationServerOption) ServerConfigOption

WithEmbeddedOAuth2Server configures our REST gateway to include an embedded OAuth 2.0 authorization server with the given parameters. This server can be used to authenticate and authorize API clients, such as our own micro-services as well as users logging in through the UI.

For the various options to configure the OAuth 2.0 server, please refer to https://pkg.go.dev/github.com/oxisto/oauth2go#AuthorizationServerOption.

In production scenarios, the usage of a dedicated authentication and authorization server is recommended.
