It is a complex of libraries for working with `TelegramBotAPI` in type-safe and strict way as much as it possible. In
the list of this complex currently next projects:

* [TelegramBotAPI](TelegramBotAPI/README.md) - core of library. In fact it is independent library and can be used alone
  without any additional library
* [TelegramBotAPI Extensions](TelegramBotAPI-extensions-api/README.md) - contains extensions (mostly for
  `RequestsExecutor`), which allows to use the core library in more pleasant way
* [TelegramBotAPI Util Extensions](TelegramBotAPI-extensions-utils/README.md) - contains extensions for more comfortable
work with commands, updates and other different things

Most part of some specific solves or unuseful
moments are describing by official [Telegram Bot API](https://core.telegram.org/bots/api).

## JavaScript notes

In case if you are want to use this library inside of browser, you will need additional settings (thanks for help to [Alexander Nozik](https://github.com/altavir)):

<summary>Gradle build script help</summary>

```groovy
dependencies {
    /* ... */

    implementation "com.github.insanusmokrassar:TelegramBotAPI:$tgbot_api_version"
    implementation "com.github.insanusmokrassar:TelegramBotAPI-extensions-api:$tgbot_api_version" // optional
    implementation "com.github.insanusmokrassar:TelegramBotAPI-extensions-utils:$tgbot_api_version" // optional

    /* Block of dependencies for correct building in browser */
    implementation(npm("fs"))
    implementation(npm("bufferutil"))
    implementation(npm("utf-8-validate"))
    implementation(npm("abort-controller"))
    implementation(npm("text-encoding"))
}

/* ... */

kotlin {
    target {
        browser {
            /* Block for fix of exception in absence of some functionality, https://github.com/ktorio/ktor/issues/1339 */
            dceTask {
                dceOptions {
                    keep("ktor-ktor-io.\$\$importsForInline\$\$.ktor-ktor-io.io.ktor.utils.io")
                }
            }
        }
    }
}
```

</details>

## Ok, where should I start?

In most cases, the most simple way will be to implement
[TelegramBotAPI Extensions](TelegramBotAPI-extensions-api/README.md) and
[TelegramBotAPI Util Extensions](TelegramBotAPI-extensions-utils/README.md) for the reason that they contains more
simple tools. If you want to dive deeper in the core of library or develop something for it - welcome to
[TelegramBotAPI](TelegramBotAPI/README.md).

Anyway, all libraries are very typical inside of them. Examples:

* In `TelegramBotAPI` common request look like `requestsExecutor.execute(SomeRequest())`
* `TelegramBotAPI-extensions-api` typical syntax look like `requestsExecutor.someRequest()` (in most cases it would be
better to use `bot` name instead of `requestsExecutor`)
* `TelegramBotAPI-extensions-utils` will look like `filter.filterBaseMessageUpdates(chatId).filterExactCommands(Regex("^.*$"))...`
