## Example of usage and comparison with `TelegramBotAPI`
As said in [TelegramBotAPI](../TelegramBotAPI/README.md#Requests), it is possible to use next syntax for requests:
Here presented review table for comparison of api from original [TelegramBotAPI](../TelegramBotAPI/README.md#Requests)
and extensions-api library:
```kotlin
val requestsExecutor: RequestsExecutor = ...
requestsExecutor.execute(GetMe())
```
This library offer a little bit another way for this:
In all examples supposed that you have created bot with next approximate lines:
```kotlin
val bot: RequestsExecutor = ...
bot.getMe()
```
The result type of [GetMe (and getMe extension)](https://github.com/InsanusMokrassar/TelegramBotAPI/blob/master/TelegramBotAPI/src/commonMain/kotlin/com/github/insanusmokrassar/TelegramBotAPI/requests/GetMe.kt)
request is
[ExtendedBot](https://github.com/InsanusMokrassar/TelegramBotAPI/blob/master/TelegramBotAPI/src/commonMain/kotlin/com/github/insanusmokrassar/TelegramBotAPI/types/User.kt).
| TelegramBotAPI | TelegramBotAPI-extensions-api |
|----------------|-------------------------------|
| bot.execute(GetMe) | bot.getMe() |
| bot.execute(SendTextMessage(someChatId, text)) | bot.sendTextMessage(chat, text) |
## Updates
Usually, it is more comfortable to use filter object to get separated types of updates:
```kotlin
val filter = FlowsUpdatesFilter(100)
```
In this case you will be able:
* Separate types of incoming updates (even media groups)
* Simplify launch of getting updates:
```kotlin
bot.startGettingOfUpdates(
filter,
scope = CoroutineScope(Dispatchers.Default)
)
```
* Use `filter` flows to comfortable filter, map and do other operations with the whole
getting updates process:
```kotlin
filter.messageFlow.mapNotNull {
it.data as? ContentMessage<*>
}.onEach {
println(it)
}.launchIn(
CoroutineScope(Dispatchers.Default)
)
```
