TeleBotFramework 1.2.0

TeleBotFramework

Minimalistic, dependency-injection-first command framework for Telegram.Bot, designed to let you build modular, maintainable Telegram bots with almost zero boilerplate.

✨ Features

• ITelegramCommand-based commands – just implement the interface
• Auto-registration of all commands found in your assemblies
• IServiceCollection extension: AddTelegramFramework(...)
• ITelegramUpdateHandler dispatches incoming updates to your commands
• IUserStateManager for per-user state persistence across sessions
• MarkdownHelper utility to safely format Markdown messages
• Ready to use in ASP.NET Core (webhook) or long-polling console apps

⚙️ Installation

dotnet add package TeleBotFramework

🚀 Usage

1. Configure your bot in ASP.NET Core (webhook)

csharp
Copy
Edit
using Microsoft.AspNetCore.Mvc;
using TeleBotFramework;
using Telegram.Bot;
using Telegram.Bot.Types;

var builder = WebApplication.CreateBuilder(args);

// 1️⃣ Register your TelegramBotClient
builder.Services.AddSingleton<ITelegramBotClient>(sp =>
{
    var cfg = sp.GetRequiredService<IConfiguration>();
    var token = cfg["Telegram:Token"];
    if (string.IsNullOrWhiteSpace(token))
        throw new ArgumentException("Telegram:Token is missing");
    return new TelegramBotClient(token);
});

// 2️⃣ Add MVC & the framework, scanning your command assembly
builder.Services.AddControllers();
builder.Services.AddTelegramFramework(typeof(StartCommand).Assembly);

var app = builder.Build();

// 3️⃣ Map the webhook endpoint
app.MapPost("/bot/webhook", async (
    [FromBody] Update update,
    [FromServices] ITelegramUpdateHandler handler) =>
{
    await handler.HandleUpdate(update);
    return Results.Ok();
});

app.Run();

2. Define a command

Create a class in your project (e.g. under Commands/) that implements ITelegramCommand:

using TeleBotFramework.Commands;
using TeleBotFramework.Models;
using Telegram.Bot;

namespace TeleBotFramework.SimpleExample.Commands
internal class StartCommand(ITelegramBotClient bot) : ITelegramCommand
{
    private readonly ITelegramBotClient _bot = bot;

    public static string Name => "/start";
    public static string Description => "Start operation";
    public static bool IsPublic => true;

    public async Task Execute(UpdateInfo update)
    {
        await _bot.SendMessage(update.ChatId, $"Hello, {update.Username ?? update.FirstName + " " + update.LastName}");
    }
}

• Name - command name to call it
• Description - will be shown in bot menu

3. Run the example

A complete ASP.NET Core example lives under: examples/TeleBotFramework.SimpleExample/
