Class Client

Namespace

Supabase.Realtime

Assembly

Supabase.Realtime.dll

Singleton that represents a Client connection to a Realtime Server.

It maintains a singular Websocket with asynchronous listeners (RealtimeChannels).

public class Client : IRealtimeClient<RealtimeSocket, RealtimeChannel>

Inheritance

object

Client

Implements

IRealtimeClient<RealtimeSocket, RealtimeChannel>

Inherited Members

object.Equals(object)

object.Equals(object, object)

object.GetHashCode()

object.GetType()

object.MemberwiseClone()

object.ReferenceEquals(object, object)

object.ToString()

Examples

client = Client.Instance

Constructors

Client(string, ClientOptions?)

Initializes a Client instance, this method should be called prior to any other method.

public Client(string realtimeUrl, ClientOptions? options = null)

Parameters

realtimeUrl string

The connection url (ex: "ws://localhost:4000/socket" - no trailing slash required)

options ClientOptions

Properties

Options

Client Options - most of which are regarding Socket connection Options

public ClientOptions Options { get; }

Property Value

ClientOptions

SerializerSettings

Custom Serializer resolvers and converters that will be used for encoding and decoding Postgrest JSON responses.

By default, Postgrest seems to use a date format that C# and Newtonsoft do not like, so this initial configuration handles that.

public JsonSerializerSettings SerializerSettings { get; }

Property Value

JsonSerializerSettings

Socket

The backing Socket class.

Most methods of the Client act as proxies to the Socket class.

public IRealtimeSocket? Socket { get; }

Property Value

IRealtimeSocket

Subscriptions

Exposes all Realtime RealtimeChannel Subscriptions for R/O public consumption

public ReadOnlyDictionary<string, RealtimeChannel> Subscriptions { get; }

Property Value

ReadOnlyDictionary<string, RealtimeChannel>

Methods

AddDebugHandler(DebugEventHandler)

Adds a debug handler, likely used within a logging solution of some kind.

public void AddDebugHandler(IRealtimeDebugger.DebugEventHandler handler)

Parameters

handler IRealtimeDebugger.DebugEventHandler

AddStateChangedHandler(SocketStateEventHandler)

Adds a listener to be notified when the socket state changes.

public void AddStateChangedHandler(IRealtimeClient<RealtimeSocket, RealtimeChannel>.SocketStateEventHandler handler)

Parameters

handler IRealtimeClient<RealtimeSocket, RealtimeChannel>.SocketStateEventHandler

Channel(string)

Adds a RealtimeChannel subscription - if a subscription exists with the same signature, the existing subscription will be returned.

public RealtimeChannel Channel(string channelName)

Parameters

channelName string

The name of the Channel to join (totally arbitrary)

Returns

RealtimeChannel

Exceptions

Exception

Channel(string, string, string, string?, string?, Dictionary<string, string>?)

Adds a RealtimeChannel subscription - if a subscription exists with the same signature, the existing subscription will be returned.

public RealtimeChannel Channel(string database = "realtime", string schema = "public", string table = "*", string? column = null, string? value = null, Dictionary<string, string>? parameters = null)

Parameters

database string

Database to connect to, with Supabase this will likely be realtime.

schema string

Postgres schema, usually public

table string

Postgres table name

column string

Postgres column name

value string

Value the specified column should have

parameters Dictionary<string, string>

Returns

RealtimeChannel

ClearDebugHandlers()

Clears debug handlers;

public void ClearDebugHandlers()

ClearStateChangedHandlers()

Clears all of the listeners from receiving socket state changes.

public void ClearStateChangedHandlers()

Connect(Action<IRealtimeClient<RealtimeSocket, RealtimeChannel>, RealtimeException?>?)

Attempts to connect to the socket.

Provides a callback for Task driven returns.

[Obsolete("Please use ConnectAsync() instead.")]
public IRealtimeClient<RealtimeSocket, RealtimeChannel> Connect(Action<IRealtimeClient<RealtimeSocket, RealtimeChannel>, RealtimeException?>? callback = null)

Parameters

callback Action<IRealtimeClient<RealtimeSocket, RealtimeChannel>, RealtimeException>

Returns

IRealtimeClient<RealtimeSocket, RealtimeChannel>

ConnectAsync()

Attempts to connect to the Socket.

Returns when socket has successfully connected.

public Task<IRealtimeClient<RealtimeSocket, RealtimeChannel>> ConnectAsync()

Returns

Task<IRealtimeClient<RealtimeSocket, RealtimeChannel>>

Disconnect(WebSocketCloseStatus, string)

Disconnects from the socket server (if connected).

public IRealtimeClient<RealtimeSocket, RealtimeChannel> Disconnect(WebSocketCloseStatus code = WebSocketCloseStatus.NormalClosure, string reason = "Programmatic Disconnect")

Parameters

code WebSocketCloseStatus

Status Code

reason string

Reason for disconnect

Returns

IRealtimeClient<RealtimeSocket, RealtimeChannel>

Remove(RealtimeChannel)

Removes a channel subscription.

public void Remove(RealtimeChannel channel)

Parameters

channel RealtimeChannel

RemoveDebugHandler(DebugEventHandler)

Removes a debug handler

public void RemoveDebugHandler(IRealtimeDebugger.DebugEventHandler handler)

Parameters

handler IRealtimeDebugger.DebugEventHandler

RemoveStateChangedHandler(SocketStateEventHandler)

Removes a specified listener from socket state changes.

public void RemoveStateChangedHandler(IRealtimeClient<RealtimeSocket, RealtimeChannel>.SocketStateEventHandler handler)

Parameters

handler IRealtimeClient<RealtimeSocket, RealtimeChannel>.SocketStateEventHandler

SetAuth(string)

Sets the JWT access token used for channel subscription authorization and Realtime RLS. Ref: https://github.com/supabase/realtime-js/pull/117 | https://github.com/supabase/realtime-js/pull/117

public void SetAuth(string jwt)

Parameters

jwt string
