Config is the main config struct for the application. Use New to instantiate a default config struct.

func NewConfig

func NewConfig() *Config

NewConfig instantiates a default new server config

type Server

type Server struct {
	// contains filtered or unexported fields
}

Server is the main server, providing the UI and API for ntfy

func New

func New(conf *Config) (*Server, error)

New instantiates a new Server. It creates the cache and adds a Firebase subscriber (if configured).

func (*Server) Run

func (s *Server) Run() error
