npm install node-tg-login
Simply use the check method
import { TelegramLogin } from 'node-tg-login'
const TelegramAuth = new TelegramLogin('<BOT_TOKEN>');
const verify = (data: TelegramLoginPayload) =>
console.log(
TelegramAuth.checkLoginData(data) ?
`Payload is safe! We can trust ${data.first_name}`,
'Uhm. Payload is not secure'
);Or as an express.js middleware like this:
import { TelegramLogin } from 'node-tg-login'
const TelegramAuth = new TelegramLogin('<BOT_TOKEN>');
app.get('/login/telegram', TelegramAuth.defaultMiddleware(), (req, res) => {
console.log(res.locals.telegram_user)
});
