35```python
36## Bot Architecture
37 
38### Stack Options
39| Language | Library | Best For |
40|----------|---------|----------|
41| Node.js | telegraf | Most projects |
42| Node.js | grammY | TypeScript, modern |
43| Python | python-telegram-bot | Quick prototypes |
44| Python | aiogram | Async, scalable |
45 
46### Basic Telegraf Setup
47```javascript
48import { Telegraf } from 'telegraf';
49 
50const bot = new Telegraf(process.env.BOT_TOKEN);
51 
52// Command handlers
53bot.start((ctx) => ctx.reply('Welcome!'));
54bot.help((ctx) => ctx.reply('How can I help?'));
55 
56// Text handler
57bot.on('text', (ctx) => {
58  ctx.reply(`You said: ${ctx.message.text}`);
59});
60 
61// Launch
62bot.launch();
63 
64// Graceful shutdown
65process.once('SIGINT', () => bot.stop('SIGINT'));
66process.once('SIGTERM', () => bot.stop('SIGTERM'));
67```

86 
87### Inline Keyboards
88 
89Interactive button interfaces
90 
91**When to use**: When building interactive bot flows
92 
93```python
94## Inline Keyboards
95 
96### Basic Keyboard
97```javascript
98import { Markup } from 'telegraf';
99 
100bot.command('menu', (ctx) => {
101  ctx.reply('Choose an option:', Markup.inlineKeyboard([
102    [Markup.button.callback('Option 1', 'opt_1')],
103    [Markup.button.callback('Option 2', 'opt_2')],
104    [
105      Markup.button.callback('Yes', 'yes'),
106      Markup.button.callback('No', 'no'),
107    ],
108  ]));
109});
110 
111// Handle button clicks
112bot.action('opt_1', (ctx) => {
113  ctx.answerCbQuery('You chose Option 1');
114  ctx.editMessageText('You selected Option 1');
115});
116```
117 
118### Keyboard Patterns
119| Pattern | Use Case |
120|---------|----------|
121| Single column | Simple menus |
122| Multi column | Yes/No, pagination |
123| Grid | Category selection |
124| URL buttons | Links, payments |
125 
126### Pagination
127```javascript
128function getPaginatedKeyboard(items, page, perPage = 5) {
129  const start = page * perPage;
130  const pageItems = items.slice(start, start + perPage);
131 
132  const buttons = pageItems.map(item =>
133    [Markup.button.callback(item.name, `item_${item.id}`)]
134  );
135 
136  const nav = [];
137  if (page > 0) nav.push(Markup.button.callback('◀️', `page_${page-1}`));
138  if (start + perPage < items.length) nav.push(Markup.button.callback('▶️', `page_${page+1}`));
139 
140  return Markup.inlineKeyboard([...buttons, nav]);
141}
142```
143```
144 
145### Bot Monetization
146 
147Making money from Telegram bots
148

158| Subscription | Monthly access | Medium |
159| Per-use | Pay per action | Low |
160| Ads | Sponsored messages | Low |
161| Affiliate | Product recommendations | Low |
162 
163### Telegram Payments
164```javascript
165// Create invoice
166bot.command('buy', (ctx) => {
167  ctx.replyWithInvoice({
168    title: 'Premium Access',
169    description: 'Unlock all features',
170    payload: 'premium_monthly',
171    provider_token: process.env.PAYMENT_TOKEN,
172    currency: 'USD',
173    prices: [{ label: 'Premium', amount: 999 }], // $9.99
174  });
175});
176 
177// Handle successful payment
178bot.on('successful_payment', (ctx) => {
179  const payment = ctx.message.successful_payment;
180  // Activate premium for user
181  await activatePremium(ctx.from.id);
182  ctx.reply('🎉 Premium activated!');
183});
184```
185 
186### Freemium Strategy
187```
188Free tier:
189- 10 uses per day
190- Basic features
191- Ads shown
192 
193Premium ($5/month):
194- Unlimited uses
195- Advanced features
196- No ads
197- Priority support
198```
199 
200### Usage Limits
201```javascript
202async function checkUsage(userId) {
203  const usage = await getUsage(userId);
204  const isPremium = await checkPremium(userId);
205 
206  if (!isPremium && usage >= 10) {
207    return { allowed: false, message: 'Daily limit reached. Upgrade?' };
208  }
209  return { allowed: true };
210}
211```
212```
213 
214## Anti-Patterns
215 
216### ❌ Blocking Operations
217 
218**Why bad**: Telegram has timeout limits.
219Users think bot is dead.
220Poor experience.
221Requests pile up.
222 
223**Instead**: Acknowledge immediately.
224Process in background.
225Send update when done.
226Use typing indicator.
227 
228### ❌ No Error Handling
229 
230**Why bad**: Users get no response.
231Bot appears broken.
232Debugging nightmare.
233Lost trust.
234 
235**Instead**: Global error handler.
236Graceful error messages.
237Log errors for debugging.
238Rate limiting.
239 
240### ❌ Spammy Bot
241 
242**Why bad**: Users block the bot.
243Telegram may ban.
244Annoying experience.
245Low retention.
246 
247**Instead**: Respect user attention.
248Consolidate messages.
249Allow notification control.
250Quality over quantity.
