Usage

create folder with your handlers TGHandlers/DefaultBotHandlers.swift

import Vapor
import TelegramVaporBot

final class DefaultBotHandlers {

    static func addHandlers(app: Vapor.Application, connection: TGConnectionPrtcl) async {
        await defaultBaseHandler(app: app, connection: connection)

            try await bot.answerCallbackQuery(params: params)
        })
    }
}

Setup

Create file TGBotConnectionActor.swift

Add Actor for TGConnection

import Foundation
import TelegramVaporBot

actor TGBotConnection {
    private var _connection: TGConnectionPrtcl!

    var connection: TGConnectionPrtcl {
        self._connection
    }
    
    func setConnection(_ conn: TGConnectionPrtcl) {
        self._connection = conn
    }
}

vapor main.swift

make strong reference to TGBotConnection instance and add "await" to configure

import Vapor
import TelegramVaporBot

let TGBOT: TGBotConnection = .init()

try await configure(app)

Use with LongPolling

for longpolling you should only configure vapor configure.swift

import TelegramVaporBot

public func configure(_ app: Application) async throws {
    let tgApi: String = "XXXXXXXXXX:YYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY"
    /// set level of debug if you needed
    TGBot.log.logLevel = app.logger.logLevel
    let bot: TGBot = .init(app: app, botId: tgApi)
    await TGBOT.setConnection(try await TGLongPollingConnection(bot: bot))
    await DefaultBotHandlers.addHandlers(app: app, connection: TGBOT.connection)
    try await TGBOT.connection.start()

    try routes(app)
}

Use with Webhooks

vapor configure.swift

import TelegramVaporBot

public func configure(_ app: Application) async throws {
    let tgApi: String = "XXXXXXXXXX:YYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY"
    /// set level of debug if you needed
    TGBot.log.logLevel = app.logger.logLevel
    let bot: TGBot = .init(app: app, botId: tgApi)
    await TGBOT.setConnection(try await TGWebHookConnection(bot: bot, webHookURL: "https://your_domain/telegramWebHook"))
    await DefaultBotHandlers.addHandlers(app: app, connection: TGBOT.connection)
    try await TGBOT.connection.start()

    try routes(app)
}

vapor routes.swift

import Vapor
import TelegramVaporBot


func routes(_ app: Application) throws {
    try app.register(collection: TelegramController())
}

vapor TelegramController.swift

import Vapor
import TelegramVaporBot

final class TelegramController: RouteCollection {
    
    func boot(routes: Vapor.RoutesBuilder) throws {
        routes.post("telegramWebHook", use: telegramWebHook)
    }
}

extension TelegramController {
    
    func telegramWebHook(_ req: Request) async throws -> Bool {
        let update: TGUpdate = try req.content.decode(TGUpdate.self)
        return try await TGBOT.connection.dispatcher.process([update])
    }
}

Add to your Vapor project with Swift Package Manager

add to yor Package.json

// swift-tools-version:5.8

import PackageDescription

var packageDependencies: [Package.Dependency] = [
    .package(url: "https://github.com/vapor/vapor.git", .upToNextMajor(from: "4.57.0")),
]

packageDependencies.append(.package(url: "https://github.com/nerzh/telegram-vapor-bot", .upToNextMajor(from: "2.1.0")))


let package = Package(
    name: "Telegram-bot-example",
    platforms: [
        .macOS(.v12)
    ],
