  A full-featured framework that empowers you to easily build [Telegram bots](https://telegram.org/blog/bot-revolution) using [Rust](https://www.rust-lang.org/). It handles all the difficult stuff so you can focus only on your business logic.
</div>

## Highlights

 - **Declarative design.** `teloxide` is based upon [`dptree`], a functional [chain of responsibility] pattern that allows you to express pipelines of message processing in a highly declarative and extensible style.

[`dptree`]: https://github.com/teloxide/dptree
[chain of responsibility]: https://en.wikipedia.org/wiki/Chain-of-responsibility_pattern

 - **Feature-rich.** You can use both long polling and webhooks, configure an underlying HTTPS client, set a custom URL of a Telegram API server, do graceful shutdown, and much more.

 - **Simple dialogues.** Our dialogues subsystem is simple and easy-to-use, and, furthermore, is agnostic of how/where dialogues are stored. For example, you can just replace a one line to achieve [persistence]. Out-of-the-box storages include [Redis], [RocksDB] and [Sqlite].

[persistence]: https://en.wikipedia.org/wiki/Persistence_(computer_science)
[Redis]: https://redis.io/
[RocksDB]: https://rocksdb.org/
[Sqlite]: https://www.sqlite.org

 - **Strongly typed commands.** Define bot commands as an `enum` and teloxide will parse them automatically — just like JSON structures in [`serde-json`] and command-line arguments in [`structopt`].

[`structopt`]: https://github.com/TeXitoi/structopt
[`serde-json`]: https://github.com/serde-rs/json

## Setting up your environment

 1. [Download Rust](http://rustup.rs/).
 2. Create a new bot using [@Botfather](https://t.me/botfather) to get a token in the format `123456789:blablabla`.
 3. Initialise the `TELOXIDE_TOKEN` environmental variable to your token:
```bash
# Unix-like
$ export TELOXIDE_TOKEN=<Your token here>

# Windows command line
$ set TELOXIDE_TOKEN=<Your token here>

# Windows PowerShell
$ $env:TELOXIDE_TOKEN=<Your token here>
```

 4. Make sure that your Rust compiler is up to date (`teloxide` currently requires rustc at least version 1.64):
```bash
# If you're using stable
$ rustup update stable
$ rustup override set stable

# If you're using nightly
$ rustup update nightly
$ rustup override set nightly
```

 5. Run `cargo new my_bot`, enter the directory and put these lines into your `Cargo.toml`:
```toml
[dependencies]
teloxide = { version = "0.11", features = ["macros"] }
log = "0.4"
pretty_env_logger = "0.4"
tokio = { version =  "1.8", features = ["rt-multi-thread", "macros"] }
```

## API overview

### The dices bot

This bot replies with a die throw to each received message:

[[`examples/throw_dice.rs`](crates/teloxide/examples/throw_dice.rs)]

```rust,no_run
use teloxide::prelude::*;

#[tokio::main]
async fn main() {
    pretty_env_logger::init();
    log::info!("Starting throw dice bot...");

    let bot = Bot::from_env();

    teloxide::repl(bot, |bot: Bot, msg: Message| async move {
        bot.send_dice(msg.chat.id).await?;
        Ok(())
    })
    .await;
}
```

<div align="center">
    <img src="./media/throw-dice.gif" width="420" />
</div>

### Commands

Commands are strongly typed and defined declaratively, similar to how we define CLI using [structopt] and JSON structures in [serde-json]. The following bot accepts these commands:

 - `/username <your username>`
 - `/usernameandage <your username> <your age>`
 - `/help`

[structopt]: https://docs.rs/structopt/0.3.9/structopt/
[serde-json]: https://github.com/serde-rs/json

[[`examples/command.rs`](crates/teloxide/examples/command.rs)]

```rust,no_run
use teloxide::{prelude::*, utils::command::BotCommands};

#[tokio::main]
async fn main() {
    pretty_env_logger::init();
    log::info!("Starting command bot...");

    let bot = Bot::from_env();

    Command::repl(bot, answer).await;
}

#[derive(BotCommands, Clone)]
#[command(rename_rule = "lowercase", description = "These commands are supported:")]
enum Command {
    #[command(description = "display this text.")]
    Help,
    #[command(description = "handle a username.")]
    Username(String),
    #[command(description = "handle a username and an age.", parse_with = "split")]
    UsernameAndAge { username: String, age: u8 },
}

async fn answer(bot: Bot, msg: Message, cmd: Command) -> ResponseResult<()> {
    match cmd {
        Command::Help => bot.send_message(msg.chat.id, Command::descriptions().to_string()).await?,
        Command::Username(username) => {
            bot.send_message(msg.chat.id, format!("Your username is @{username}.")).await?
        }
        Command::UsernameAndAge { username, age } => {
            bot.send_message(msg.chat.id, format!("Your username is @{username} and age is {age}."))
                .await?
        }
    };

    Ok(())
}
```

    <img src="./media/command.gif" width="420" />
</div>

### Dialogues management

A dialogue is typically described by an enumeration where each variant is one possible state of the dialogue. There are also _state handler functions_, which may turn a dialogue from one state to another, thereby forming an [FSM].

[FSM]: https://en.wikipedia.org/wiki/Finite-state_machine

Below is a bot that asks you three questions and then sends the answers back to you:

[[`examples/dialogue.rs`](crates/teloxide/examples/dialogue.rs)]

```rust,ignore
use teloxide::{dispatching::dialogue::InMemStorage, prelude::*};

type MyDialogue = Dialogue<State, InMemStorage<State>>;
type HandlerResult = Result<(), Box<dyn std::error::Error + Send + Sync>>;

#[derive(Clone, Default)]
pub enum State {
    #[default]
    Start,
    ReceiveFullName,
    ReceiveAge {
        full_name: String,
    },
    ReceiveLocation {
        full_name: String,
        age: u8,
    },
}

#[tokio::main]
async fn main() {
    pretty_env_logger::init();
    log::info!("Starting dialogue bot...");

    let bot = Bot::from_env();

    Dispatcher::builder(
        bot,
        Update::filter_message()
            .enter_dialogue::<Message, InMemStorage<State>, State>()
            .branch(dptree::case![State::Start].endpoint(start))
            .branch(dptree::case![State::ReceiveFullName].endpoint(receive_full_name))
            .branch(dptree::case![State::ReceiveAge { full_name }].endpoint(receive_age))
            .branch(
                dptree::case![State::ReceiveLocation { full_name, age }].endpoint(receive_location),
            ),
    )
    .dependencies(dptree::deps![InMemStorage::<State>::new()])
    .enable_ctrlc_handler()
    .build()
    .dispatch()
    .await;
}

async fn start(bot: Bot, dialogue: MyDialogue, msg: Message) -> HandlerResult {
    bot.send_message(msg.chat.id, "Let's start! What's your full name?").await?;
    dialogue.update(State::ReceiveFullName).await?;
    Ok(())
}

async fn receive_full_name(bot: Bot, dialogue: MyDialogue, msg: Message) -> HandlerResult {
    match msg.text() {
        Some(text) => {
            bot.send_message(msg.chat.id, "How old are you?").await?;
            dialogue.update(State::ReceiveAge { full_name: text.into() }).await?;
        }
        None => {
            bot.send_message(msg.chat.id, "Send me plain text.").await?;
        }
    }

    Ok(())
}

async fn receive_age(
    bot: Bot,
    dialogue: MyDialogue,
    full_name: String, // Available from `State::ReceiveAge`.
    msg: Message,
) -> HandlerResult {
    match msg.text().map(|text| text.parse::<u8>()) {
        Some(Ok(age)) => {
            bot.send_message(msg.chat.id, "What's your location?").await?;
            dialogue.update(State::ReceiveLocation { full_name, age }).await?;
        }
        _ => {
            bot.send_message(msg.chat.id, "Send me a number.").await?;
        }
    }

    Ok(())
}

async fn receive_location(
    bot: Bot,
    dialogue: MyDialogue,
    (full_name, age): (String, u8), // Available from `State::ReceiveLocation`.
    msg: Message,
) -> HandlerResult {
    match msg.text() {
        Some(location) => {
            let report = format!("Full name: {full_name}\nAge: {age}\nLocation: {location}");
            bot.send_message(msg.chat.id, report).await?;
            dialogue.exit().await?;
        }
        None => {
            bot.send_message(msg.chat.id, "Send me plain text.").await?;
        }
    }

    Ok(())
}
```
