Lets start a Node.js server that is supposed to respond back to the start command.

• Initialise a node.js project

bun init

• Add dependencies

bun add telegraf

• Add a start command handler

import { Telegraf, Markup, Context } from 'telegraf';

const bot = new Telegraf(BOT_TOKEN);

bot.start(async (ctx: BotContext) => {
    const userId = ctx.from?.id;
    if (!userId) return;
    
    const payload = ctx.startPayload;
    
    let welcomeMessage = `

    return ctx.reply(welcomeMessage, {
        parse_mode: 'Markdown',
        ...Markup.inlineKeyboard([
            [
                Markup.button.callback('🔑 Generate Wallet', 'generate_wallet'),

            ]
        ])
    });
});

async function startBot(): Promise<void> {
    try {
        await bot.launch({
            allowedUpdates: ['message', 'callback_query']
        });        
    } catch (error) {
        console.error('❌ Failed to start bot:', error);
        process.exit(1);
    }
}

// Start the bot
startBot();
