TimeMates SDK

The TimeMates SDK is a software development kit that provides support for the TimeMates API, which is built on top of gRPC. It offers a convenient and efficient way to interact with the TimeMates platform and integrate its features into your own applications.

Usages example

To demonstrate the usage of the SDK, consider the following example:

val engine = RSocketTimeMatesRequestsEngine(
    coroutineScope = Dispatchers.IO,
)
val emailAuth = AccountLoginApi(engine).email
val email = EmailAddress.factory
    .createSafe("[email protected]")
    .toResult()
    .getOrElse { return }

val authorizationResult = emailAuth.authorize(email)
    // requestCode returns ConfirmationCode from user
    .map { verificationHash -> verificationHash to requestCode() }
    .map { (verificationHash, code) -> emailAuth.confirm(verificationHash, verificationHash) }
    // if it's new account, there's no authorization present
    // until we complete our registration
    .map { (isNewAccount, authorization) -> ... }

In the provided code snippet, the SDK utilizes the Kotlin Result API extensively.

It's important to note that the SDK's value objects, such as EmailAddress and ConfirmationCode, also employ the Result API. This ensures that the validation process is properly handled, and the client can take appropriate actions based on the success or failure of the operations.

Pagination

In some cases, we need to get a large set of data (for example, list of timers or members). We can use extensions provided for Api classes:

val timersApi: TimersApi = TimersApi(createEngine(), getTokenProvider())
val iterator = timersApi.getUserTimersPages() // lazy iterator, it queries server only on `next()`

// using collections (loads everything at once)
iterator.toList().forEach { timer -> println(timer.name.string) }

// using flow
iterator.asFlow()
    .collectLatest { page -> println(page.joinToString("\n")) }

// using sequences (actually, it's just toList() + asSequence() from stdlib)
iterator.asSequence()
    .map { timer -> timer.name.string }
    .forEach { name -> println(name) }

// iterate directly
iterator.forEachPage { page -> /* ... */ }
iterator.forEach { timer -> /* ... */ }

Warning
asSequence is experimental API and needs more considerations about possible misunderstanding of non-laziness way of loading and iterating data at start. You can just use iterator.toList().asSequence() or simply opt-in ExperimentalApi annotation.

Overall, you can take a look at sources of PagesIterator to get more information.

Implementation

Warning
This is a very-very alpha version of the library, and it can contain unexpected bugs among with changing of public API.

You can implement sdk in next way:

repositories {
    maven("https://maven.timemates.org/releases")
    // if you want, you can also use dev builds:
    maven("https://maven.timemates.org/dev")
}

dependencies {
    implementation("org.timemates:sdk:$version")
    implementation("org.timemates:rsocket-engine:$version")
}
