TDL Coroutines
September 4, 2026 ยท View on GitHub
TDL Coroutines is a Kotlin Multiplatform library that provides a coroutine-based client for the Telegram Database Library (TDLib). It simplifies sending requests and handling updates, making TDLib integration more straightforward and idiomatic for Kotlin Multiplatform projects.

Usage
Caution
Upstream TDLib may include breaking API changes even in patch releases. Since TDL Coroutines wraps TDLib, these changes propagate to this library as well. To minimize the impact, use named arguments when calling generated constructors and request methods, because parameters may be added, renamed, or removed in future releases.
Create a client
val client = TdlClient.create()
Important
Start collecting the update flows you need before sending the first request.
Subscribe to updates
TdlClient provides 189 update flows and the allUpdates flow, which combines all update events.
coroutineScope.launch {
client.authorizationStateUpdates.collect { update ->
val authorizationState = update.authorizationState
// TODO
}
}
coroutineScope.launch {
client.allUpdates.collect { update ->
when (update) {
is UpdateAuthorizationState -> {
val authorizationState = update.authorizationState
// TODO
}
is UpdateOption -> {
val name = update.name
val value = update.value
// TODO
}
// TODO
}
}
}
Send a request
TdlClient provides 1022 request methods.
coroutineScope.launch {
val result = client.getAuthorizationState()
when (result) {
is TdlResult.Failure -> {
val code = result.code
val message = result.message
// TODO
}
is TdlResult.Success -> {
val authorizationState = result.result
// TODO
}
}
}
Tip
You can use the .toResult() extension to convert TdlResult<T> to the standard Kotlin Result<T> type.
