Querying Users

The Query Users method allows you to search for users and see if they are online/offline. The example below shows how you can retrieve the details for 3 users in one API call:

// Search for users with id "john", "jack", or "jessie"
val request = QueryUsersRequest(
  filter = Filters.`in`("id", listOf("john", "jack", "jessie")),
  offset = 0,
  limit = 3,
)

client.queryUsers(request).enqueue { result ->
  if (result is Result.Success) {
    val users: List<User> = result.value
  } else {
    // Handle Result.Failure 
  }
}

const response = await client.queryUsers({
  id: { $in: ["john", "jack", "jessie"] },
});

// Search users with id "john", "jack", or "jessie"
FilterObject filter = Filters.in("id", Arrays.asList("john", "jack", "jessie"));
int offset = 0;
int limit = 3;
QueryUsersRequest request = new QueryUsersRequest(filter, offset, limit);

client.queryUsers(request).enqueue(result -> {
  if (result.isSuccess()) {
    List<User> users = result.data();
  } else {
    // Handle result.error()
  }
});

let controller = chatClient.userListController(
  query: .init(filter: .in(.id, values: ["john", "jack", "jessie"]))
)

controller.synchronize { error in
  if let error = error {
    // handle error
    print(error)
  } else {
    // access users
    print(controller.users)
  }
}

$response = $client->queryUsers([ 'id' => ['$in' => ['john', 'jack', 'jessie'] ] ]);

final _result = client.queryUsers(
 filter: Filter.in_(['john', 'jack', 'jessie']),
);

Client->QueryUsers(
  FFilter::In(TEXT("id"), {TEXT("john"), TEXT("jack"), TEXT("jessie")}),
  {},   // Sort
  true,  // Presence
  {},   // Pagination options
  [](const TArray<FUserRef>& Users)
  {
    // Do something with Users
  });

var resp = await userClient.QueryAsync(QueryUserOptions.Default.WithFilter(new Dictionary<string, object>
{
  { "id", new Dictionary<string, object> { { "$in", new[]{ "john", "jack", "jassie" } } } },
}));

client.query_users({"id": {"$in": ["Jack", "Joe", "Jesie"]}})

var filters = new IFieldFilterRule[]
{
  UserFilter.Id.In("user-1", "user-2", "user-3")
};
// Returns collection of IStreamUser
var users = await Client.QueryUsersAsync(filters);

# require 'stream-chat'

client.query_users({"id": {"$in": ["Jack", "Joe", "Jesie"]}})

val request = QueryUsersRequest(
  filter = Filters.`in`("id", listOf("jessica")),
  querySort = QuerySortByField.descByName("last_active"),
  offset = 0,
  limit = 1,
  presence = true,
)
client.queryUsers(request).enqueue { /* ... */ }

const response = await client.queryUsers(
  { id: { $in: ["jessica"] } },
  { last_active: -1 },
  { presence: true },
);

let controller = chatClient.userListController(
  query: .init(
    filter: .in(.id, values: ["john", "jack", "jessie"]),
    sort: [.init(key: .lastActivityAt, isAscending: false)]
  )
)

controller.synchronize { error in
  if let error = error {
    // handle error
    print(error)
  } else {
    // access users
    print(controller.users)
  }
}

// load more if needed
controller.loadNextUsers(limit: 10) { error in
  // handle error / access users
}

$response = $client->queryUsers(
[
 'id' => ['$in' => ['john', 'jack', 'jessie'] ],
 'last_active' => '2019-11-05T21:35:24.397995Z',
]);

final _result = client.queryUsers(
 filter: Filter.in_(['john', 'jack', 'jessie']),
 sort: [SortOption('last_active')],
 pagination: PaginationParams(
  offset: 0,
  limit: 20,
 ),
);

Client->QueryUsers(
  FFilter::In(TEXT("id"), {TEXT("john"), TEXT("jack"), TEXT("jessie")}),
  {FUserSortOption{EUserSortField::LastActive}},
  true,     // bPresence
  {{20, 0}},  // Pagination options
  [](const TArray<FUserRef>& Users)
  {
    // Do something with Users
  });

var query = QueryUserOptions.Default.WithFilter(new Dictionary<string, object>
{
  { "id", new Dictionary<string, object> { { "$in", new[]{"jessica"} } } },
});
query.Presence = true;

var resp = await userClient.QueryAsync(query);

client.query_users({"id": {"$eq": "Jessica"}}, { "last_active": -1})

var lastWeek = DateTime.Now.AddDays(-7);
var filters = new IFieldFilterRule[]
{
  UserFilter.CreatedAt.GreaterThanOrEquals(lastWeek)
};

// Order results by one or multiple fields e.g
var sort = UsersSort.OrderByDescending(UserSortField.CreatedAt);

var limit = 30; // How many records per page
var offset = 0; // How many records to skip e.g. offset = 30 -> page 2, offset = 60 -> page 3, etc.

// Returns collection of IStreamUser
var users = await Client.QueryUsersAsync(filters, sort, offset, limit);

client.query_users({"id": {"$eq": "Jessica"}}, { "last_active": -1})

Another option is to query for banned users. This can be done with the following code snippet:

val request = QueryUsersRequest(
  filter = Filters.eq("banned", true),
  offset = 0,
  limit = 10,
)

client.queryUsers(request).enqueue { /* ... */ }

const banned = await client.queryUsers({ id: "jessica", banned: true });

$banned = $client->queryUsers(
[
 'id' => 'bob-1',
 'banned' => true,
]);

let controller = chatClient.userListController(
  query: .init(
    filter: .equal(.isBanned, to: true),
    sort: [.init(key: .lastActivityAt, isAscending: false)]
  )
)

controller.synchronize { error in
  if let error = error {
    // handle error
    print(error)
  } else {
    // access users
    print(controller.users)
  }
}

FilterObject filter = Filters.eq("banned", true);
int offset = 0;
int limit = 10;
QueryUsersRequest request = new QueryUsersRequest(filter, offset, limit);

client.queryUsers(request).enqueue(result -> { /* ... */ });

final _result = client.queryUsers(
 filter: Filter.and(
  Filter.equal('id', 'jessie'),
  Filter.equal('banned', true),
 ),
 sort: [SortOption('last_active')],
 pagination: PaginationParams(
  offset: 0,
  limit: 20,
 ),
);

Client->QueryUsers(
  FFilter::And({
    FFilter::Equal(TEXT("id"), TEXT("jessie")),
    FFilter::Equal(TEXT("banned"), true),
  }),
  {FUserSortOption{EUserSortField::LastActive}},
  true,  // Presence
  {},   // Pagination options
  [](const TArray<FUserRef>& Users)
  {
    // Do something with Users
  });

var resp = await userClient.QueryAsync(QueryUserOptions.Default.WithFilter(new Dictionary<string, object>
{
  { "id", new Dictionary<string, object> { { "$in", new[]{ "john" } } } },
  { "banned": true },
}));

client.query_users({"id": {"$eq": "Jessica"}, "banned": True})

// Returns collection of StreamUserBanInfo
var usersBanInfo = await Client.QueryBannedUsersAsync(new StreamQueryBannedUsersRequest
{
  CreatedAtAfter = null, // Optional Banned after this date
  CreatedAtAfterOrEqual = null, // Optional Banned after or equal this date
  CreatedAtBefore = null, // Optional Banned before this date
  CreatedAtBeforeOrEqual = null, // Optional Banned before or equal this date
  FilterConditions = null, // Optional filter
  Limit = 30,
  Offset = 60,
  Sort = new List<StreamSortParam> // Optional sort
  {
    new StreamSortParam
    {
      Field = "created_at",
      Direction = -1,
    }
  },
});

foreach (var banInfo in usersBanInfo)
{
  Debug.Log(banInfo.User); // Which user
  Debug.Log(banInfo.Channel); // From which channel
  Debug.Log(banInfo.Reason); // Reason why banned
  Debug.Log(banInfo.Expires); // Optional expiry date
  Debug.Log(banInfo.Shadow); // Is this a shadow ban
  Debug.Log(banInfo.BannedBy); // Who created a ban
  Debug.Log(banInfo.CreatedAt); // Date when banned
}

client.query_users({"id": {"$eq": "Jessica"}, "banned": true})

An object with an array of users will be returned.

Please be aware that this query will return users banned across the entire app, not at a channel level.

All filters use a Mongoose style syntax; however, we do not run MongoDB on the backend, so you can only use a subset of queries that are normally available within Mongoose. The supported queries are described below.

You can filter and sort on the custom fields you’ve set for your user, the user id, and when the user was last active.

Supported queries

The options for the queryUser method are include_deactivated_users, presence, limit, and offset. If presence is true this makes sure you receive the user.presence.changed event when a user goes online or offline.

name	type	description	default	optional
filter_conditions	objects	Conditions to use to filter the users	-
presence	boolean	Get updates when the user goes offline/online	true	✓
sort	object or array of objects	The sorting used for the users matching the filters. Sorting is based on field and direction, and multiple sorting options can be provided. Direction can be ascending (1) or descending (-1).	[{created_at: -1}, {id: -1}]	✓
limit	integer	Number of users to return	30	✓
offset	integer	Offset for pagination	0	✓
id_gt	string	ID-based pagination. Return IDs greater than this ID. If this is not empty, the default sort order will be [{id: -1}].	-	✓
id_gte	string	ID-based pagination. Return IDs greater than or equal to this ID. If this is not empty, the default sort order will be [{id: -1}].	-	✓
id_lt	string	ID-based pagination. Return IDs less than this ID. If this is not empty, the default sort order will be [{id: -1}].	-	✓
id_lte	string	ID-based pagination. Return IDs less than or equal to this ID. If this is not empty, the default sort order will be [{id: -1}].	-	✓
include_deactivated_users	boolean	Include deactivated users in the response	-	✓

You can subscribe to presence status of at most 30 users using this method.

Note - The offset limit is set to 1000.

Filter conditions

Name	Type	Description	allowed operators
id	string	ID of the user	$eq, $gt, $gte, $lt, $lte, $in, $autocomplete

Querying Using the $autocomplete Operator

You can autocomplete the results of your user query by username and/or ID.

1. By Name

If you want to return all users whose field 'name' has a value that includes 'ro', you could do so with the following:

val request = QueryUsersRequest(
  filter = Filters.autocomplete("name", "ro"),
  offset = 0,
  limit = 10,
)

client.queryUsers(request).enqueue { /* ... */ }

const response = await serverClient.queryUsers({
  name: { $autocomplete: "ro" },
});

$response = $client->queryUsers(
[
 'name' => ['$autocomplete' => 'ro']
]);

let controller = chatClient.userListController(
  query: .init(filter: .autocomplete(.name, text: "ro"))
)

controller.synchronize { error in
  if let error = error {
    // handle error
    print(error)
  } else {
    // access users
    print(controller.users)
  }
}

FilterObject filter = Filters.autocomplete("name", "ro");
int offset = 0;
int limit = 10;
QueryUsersRequest request = new QueryUsersRequest(filter, offset, limit);

client.queryUsers(request).enqueue(result -> { /* ... */ });

final _result = client.queryUsers(
 filter: Filter.autoComplete('name', 'ro'),
);

Client->QueryUsers(
  FFilter::Autocomplete(TEXT("name"), TEXT("ro")),
  {},   // Sort
  true,  // Presence
  {},   // Pagination options
  [](const TArray<FUserRef>& Users)
  {
    // Do something with Users
  });

var resp = await _userClient.QueryAsync(QueryUserOptions.Default.WithFilter(new Dictionary<string, object>
{
  { "name", new Dictionary<string, object> { { "$autocomplete", "ro" } } },
}));

client.query_users({"name": {"$autocomplete": "ro"}})

client.query_users({"name": {"$autocomplete": "ro"}})

var filters = new IFieldFilterRule[]
{
  UserFilter.Name.Autocomplete("Ro")
};
// Returns collection of IStreamUser
var users = await Client.QueryUsersAsync(filters);

This would return an array of any matching users, such as:

[
  {
    "id": "userID",
    "name": "Curiosity Rover"
  },
  {
    "id": "userID2",
    "name": "Roxy"
  },
  {
    "id": "userID3",
    "name": "Roxanne"
  }
]

2. By ID

val request = QueryUsersRequest(
  filter = Filters.autocomplete("id", "USER_ID"),
  offset = 0,
  limit = 10,
)

client.queryUsers(request).enqueue { /* ... */ }

const response = await client.queryUsers({ id: { $autocomplete: "USER_ID" } });

$response = $client->queryUsers(
[
 'id' => ['$autocomplete' => 'user-id']
]);

let controller = chatClient.userListController(
  query: .init(filter: .autocomplete(.id, text: "ro"))
)

controller.synchronize { error in
  if let error = error {
    // handle error
    print(error)
  } else {
    // access users
    print(controller.users)
  }
}

FilterObject filter = Filters.autocomplete("id", "USER_ID");
int offset = 0;
int limit = 10;
QueryUsersRequest request = new QueryUsersRequest(filter, offset, limit);

client.queryUsers(request).enqueue(result -> { /* ... */ });

final _result = client.queryUsers(
 filter: Filter.autocomplete('id', 'userid'),
);

Client->QueryUsers(
  FFilter::Autocomplete(TEXT("id"), TEXT("userid")),
  {},   // Sort
  true,  // Presence
  {},   // Pagination options
  [](const TArray<FUserRef>& Users)
  {
    // Do something with Users
  });

var resp = await _userClient.QueryAsync(QueryUserOptions.Default.WithFilter(new Dictionary<string, object>
{
  { "name", new Dictionary<string, object> { { "$autocomplete", userId } } },
}));

client.query_users({"name": {"$autocomplete": user_id}})

client.query_users({"name": {"$autocomplete": user_id}})

var filters = new IFieldFilterRule[]
{
  // Return all users with Id starting with `Ro` like: Roxy, Roxanne, Rover
  UserFilter.Name.Autocomplete("Ro")
};
// Returns collection of IStreamUser
var users = await Client.QueryUsersAsync(filters);
