Functions

func Execute

func Execute(options Options)

Execute starts a go-waku node with settings determined by the Options parameter

func ExtractDBAndMigration

func ExtractDBAndMigration(databaseURL string) (*sql.DB, func(*sql.DB) error, error)

Types

type DNSDiscoveryOptions

type DNSDiscoveryOptions struct {
	Enable     bool
	URLs       cli.StringSlice
	Nameserver string
}

DNSDiscoveryOptions are settings used for enabling DNS-based discovery protocol that stores merkle trees in DNS records which contain connection information for nodes. It's very useful for bootstrapping a p2p network.

type DiscV5Options

type DiscV5Options struct {
	Enable     bool
	Nodes      cli.StringSlice
	Port       uint
	AutoUpdate bool
}

DiscV5Options are settings to enable a modified version of Ethereum’s Node Discovery Protocol v5 as a means for ambient node discovery.

type FilterOptions

type FilterOptions struct {
	Enable          bool
	UseV2           bool
	DisableFullNode bool
	Nodes           []multiaddr.Multiaddr
	Timeout         time.Duration
}

FilterOptions are settings used to enable filter protocol. This is a protocol that enables subscribing to messages that a peer receives. This is a more lightweight version of WakuRelay specifically designed for bandwidth restricted devices.

type LightpushOptions

type LightpushOptions struct {
	Enable bool
	Nodes  []multiaddr.Multiaddr
}

LightpushOptions are settings used to enable the lightpush protocol. This is a lightweight protocol used to avoid having to run the relay protocol which is more resource intensive. With this protocol a message is pushed to a peer that supports both the lightpush protocol and relay protocol. That peer will broadcast the message and return a confirmation that the message was broadcasted

type MetricsOptions

type MetricsOptions struct {
	Enable  bool
	Address string
	Port    int
}

MetricsOptions are settings used to start a prometheus server for obtaining useful node metrics to monitor the health of behavior of the go-waku node.

type Options

type Options struct {
	Port               int
	Address            string
	Dns4DomainName     string

	KeepAlive          time.Duration
	AdvertiseAddresses []multiaddr.Multiaddr
	ShowAddresses      bool
	LogLevel           string
	LogEncoding        string
	LogOutput          string
	NAT                string
	PersistPeers       bool
	UserAgent          string
	PProf              bool

	PeerExchange PeerExchangeOptions
	Websocket    WSOptions
	Relay        RelayOptions
	Store        StoreOptions
	Swap         SwapOptions
	Filter       FilterOptions
	LightPush    LightpushOptions
	RLNRelay     RLNRelayOptions
	DiscV5       DiscV5Options
	DNSDiscovery DNSDiscoveryOptions
	Rendezvous   RendezvousOptions
	Metrics      MetricsOptions
	RPCServer    RPCServerOptions
	RESTServer   RESTServerOptions
}

Options contains all the available features and settings that can be configured via flags when executing go-waku as a service.

type PeerExchangeOptions

type RLNRelayOptions

type RLNRelayOptions struct {
	Enable                    bool
	CredentialsPath           string
	CredentialsPassword       string
	MembershipIndex           int
