A highly opinionated telegram bot framework, mainly based on Telegram.Bot.

The only requirement is Microsoft.AspNetCore.App (>= 8.0).

The usage is very simple yet powerful:

...
using Navigator;
... 

var builder = WebApplication.CreateBuilder(args);

builder.Services.AddMemoryCache();

builder.Services.AddNavigator(options =>
{
    options.SetWebHookBaseUrl(builder.Configuration["BASE_WEBHOOK_URL"]!);
    options.SetTelegramToken(builder.Configuration["TELEGRAM_TOKEN"]!);
});

var app = builder.Build();

var bot = app.GetBot();

// This action will be triggered if the user sends a message in the style of `/join <text> <text>`.
bot.OnCommand("join", async (INavigatorClient client, Chat chat, string[] parameters) =>
{
    var result = string.Join(',', parameters);

    await client.SendTextMessageAsync(chat, result);
});

app.MapNavigator();

app.Run();

After installing the package you can start using it by first configuring Navigator:

builder.Services.AddNavigator(options =>
{
    // Configuration here!
});

Inside the AddNavigator method you can define the following options:

• The WebHook base URL:options.SetWebHookBaseUrl(string)
• The Telegram token: options.SetTelegramToken(string)
• Optionally, the WebHook endpoint: options.SetWebHookEndpoint(string)
• Optionally, allow multiple actions for the same update: options.EnableMultipleActionsUsage()
• Optionally, enable the sending of chat actions (e.g. typing) notifications: options.EnableChatActionNotification()

Continue by defining the actions of your bot using the different helper methods (see source code for more details).

Finally add the following line to map the endpoint to the navigator framework:

app.MapNavigator();

This will start the server and will listen for incoming requests from Telegram. Your bot is good to go!

Navigator comes with a few extensions:

• Navigator.Extensions.Probabilities: Easily configure the probabilities of a bot action being executed.
• Navigator.Extensions.Cooldown: Easily configure the cooldown of an action.

You can find them in nuget by searching for Navigator.Extensions..

Some examples can be found in the samples repository.

Also checkout some bots made with Navigator:

• @ThankiesBot, check out it's source code.
• @FOSCBot, check out it's source code.
