📝 About Stream

You can sign up for a Stream account at our Get Started page.

You can use this library to access chat API endpoints server-side.

For the client-side integrations (web and mobile) have a look at the JavaScript, iOS and Android SDK libraries (docs).

🚨 Breaking changes in v1.0 <

The library received many changes in v1.0 to make it easier to use and more maintanable in the future. The main change is that both Channel and Client classes have been separated into small modules that we call clients. (This resambles the structure of our Java library as well.) Main changes:

Channel and Client classes are gone, and have been organized into smaller clients in StreamChat.Clients namespace.

These clients do not maintain state as Channel used to did earlier where it kept the channelType and channelId in the memory. So this means that you'll need to pass in channelType and channelId to a lot of method calls in IChannelClient.

Async method names have Async suffix now.

All public methods and classes have documentation.

Identifiers has been renamed from ID to Id to follow Microsoft's naming guide. Such as userID -> userId.

A lot of data classes have been renamed to make more sense. Such as ChannelObject -> Channel.

Data classes have been moved to StreamChat.Models namespace.

Full feature parity: all backend APIs are available.

Returned values are type of ApiResponse and expose rate limit informaiton with GetRateLimit() method.

The folder structure of the project has been reorganized to follow Microsoft's recommendation.

Unit tests have been improved. They are smaller, more focused and have cleanup methods.

Added .NET 6.0 support.

The proper usage of the library:
var clientFactory = new StreamClientFactory("YourApiKey", "YourApiSecret");
// Note: all client instances can be used as a singleton for the lifetime
// of your application as they don't maintain state.
var userClient = clientFactory.GetUserClient();
var channelClient = clientFactory.GetChannelClient();
var messageClient = clientFactory.GetMessageClient();
var reactionClient = clientFactory.GetReactionClient();

var jamesBond = await userClient.UpsertAsync(new UserRequest { Id = "james_bond" });
var agentM = await userClient.UpsertAsync(new UserRequest { Id = "agent_m" });

var channel = await channelClient.GetOrCreateAsync("messaging", "superHeroChannel", createdBy: jamesBond.Id);
await channelClient.AddMembersAsync(channel.Type, channel.Id, jamesBond.Id, agentM.Id);

var message = await messageClient.SendMessageAsync(channel.Type, channel.Id, jamesBond.Id, "I need a new quest Agent M.");
await reactionClient.SendReactionAsync(message.Id, "like", agentM.Id);

⚙️ Installation

$ dotnet add package stream-chat-net

💡 Tip: you can find code samples in the samples folder.

✨ Getting started

Import

using StreamChat.Clients;

Initialize client

// Client factory instantiation.
var clientFactory = new StreamClientFactory("YourApiKey", "YourApiSecret");

// Or you can configure some options such as custom HttpClient, HTTP timeouts etc.
var clientFactory = new StreamClientFactory("YourApiKey", "YourApiSecret", opts => opts.Timeout = TimeSpan.FromSeconds(5));

// Get clients from client factory. Note: all clients can be used as a singleton in your application.
var channelClient = clientFactory.GetChannelClient();
var messageClient = clientFactory.GetMessageClient();

Generate a token for client-side usage

var userClient = clientFactory.GetUserClient();

// Without expiration
var token = userClient.CreateToken("bob-1");

// With expiration
var token = userClient.CreateToken("bob-1", expiration: DateTimeOffset.UtcNow.AddHours(1));

Create/Update users

var userClient = clientFactory.GetUserClient();

var bob = new UserRequest
{
    Id = "bob-1",
    Role = Role.Admin,
    Teams = new[] { "red", "blue" } // if multi-tenant enabled
};
bob.SetData("age", 27);

await userClient.UpsertAsync(bob);

// Batch update is also supported
var jane = new UserRequest { Id = "jane"};
var june = new UserRequest { Id = "june"};
var users = await userClient.UpsertManyAsync(new[] { bob, jane, june });

GDPR-like User endpoints

var userClient = clientFactory.GetUserClient();

await userClient.ExportAsync("bob-1");
await userClient.DeactivateAsync("bob-1");
await userClient.ReactivateAsync("bob-1");
await userClient.DeleteAsync("bob-1");

Channel types

var channelTypeClient = clientFactory.GetChannelTypeClient();

var chanTypeConf = new ChannelTypeWithStringCommands
{
    Name = "livechat",
    Automod = Automod.Disabled,
    Commands = new List<string> { Commands.Ban },
    Mutes = true
};
var chanType = await channelTypeClient.CreateChannelTypeAsync(chanTypeConf);

var allChanTypes = await channelTypeClient.ListChannelTypesAsync();

Channels

var channelClient = clientFactory.GetChannelClient();

// Create a channel with members from the start, Bob is the creator
var channel = channelClient.GetOrCreateAsync("messaging", "bob-and-jane", bob.Id, bob.Id, jane.Id);

// Create channel and then add members, Mike is the creator
var channel = channelClient.GetOrCreateAsync("messaging", "bob-and-jane", mike.Id);
channelClient.AddMembersAsync(channel.Type, channel.Id, bob.Id, jane.Id, joe.Id);

Messaging

var messageClient = clientFactory.GetMessageClient();

// Only text
messageClient.SendMessageAsync(channel.Type, channel.Id, bob.Id, "Hey, I'm Bob!");

// With custom data
var msgReq = new MessageRequest { Text = "Hi june!" };
msgReq.SetData("location", "amsterdam");

var bobMessageResp = await messageClient.SendMessageAsync(channelType, channel.Id, msgReq, bob.Id);

// Threads
var juneReply = new MessageRequest { Text = "Long time no see!" };
var juneReplyMessage = await messageClient.SendMessageToThreadAsync(channel.Type, channel.Id, juneReply, june.Id, bobMessageResp.Message.Id)

Reactions

var reactionClient = clientFactory.GetReactionClient();

await reactionClient.SendReactionAsync(message.Id, "like", bob.Id);

var allReactions = await reactionClient.GetReactionsAsync(message.Id);

Moderation

var channelClient = clientFactory.GetChannelClient();
var userClient = clientFactory.GetUserClient();
var flagClient = clientFactory.GetFlagClient();

await channelClient.AddModeratorsAsync(channel.Type, channel.Id, new[] { jane.Id });

await userClient.BanAsync(new BanRequest
{
    Type = channel.Type,
    Id = channel.Id,
    Reason = "reason",
    TargetUserId = bob.Id,
    UserId = jane.Id
});

await flagClient.FlagUserAsync(bob.Id, jane.Id);

Permissions

var permissionClient = clientFactory.GetPermissionClient();

await permissionClient.CreateRoleAsync("channel-boss");

// Assign users to roles (optional message)
await channelClient.AssignRolesAsync(new AssignRoleRequest
{
    AssignRoles = new List<RoleAssignment>
    {
        new RoleAssignment { UserId = bob.ID, ChannelRole = Role.ChannelModerator },
        new RoleAssignment { UserId = june.ID, ChannelRole = "channel-boss" }
    },
    Message = new MessageRequest { Text = "Bob and June just became mods", User = bob }
});

Devices

var deviceClient = clientFactory.GetDeviceClient();

var junePhone = new Device
{
    ID = "iOS Device Token",
    PushProvider = PushProvider.APN,
    UserId = june.ID
};

await deviceClient.AddDeviceAsync(junePhone);

var devices = await deviceClient.GetDevicesAsync(june.Id);

Export Channels

var channelClient = clientFactory.GetChannelClient();
var taskClient = clientFactory.GetTaskClient();

var taskResponse = channelClient.ExportChannelAsync(new ExportChannelRequest { Id = channel.Id, Type = channel.Type });

// Wait for the completion
var complete = false;
var iterations = 0;
AsyncTaskStatusResponse resp = null;
while (!complete && iterations < 1000)
{
    resp = await taskClient.GetTaskStatusAsync(taskResponse.TaskId);
    if (resp.Status == AsyncTaskStatus.Completed)
    {
        complete = true;
        break;
    }
    iterations++;
    await Task.Delay(100);
}

if (complete)
{
    Console.WriteLine(resp.Result["url"]);
}
