cfworker-middware-telegraf


Make telegraf (a telegram bot framework) useable in Cloudflare Workers.

Installation

``bash
npm i cfworker-middware-telegraf
`

Usage

$3

`js
// index.js
const { Telegraf } = require('telegraf');
const { Application, Router } = require('@cfworker/web');
const createTelegrafMiddware = require('cfworker-middware-telegraf');

const bot = new Telegraf('BOT_TOKEN');

// Your code here, but do not bot.launch()

const router = new Router();
router.post('/SECRET_PATH', createTelegrafMiddware(bot));
new Application().use(router.middleware).listen();
`

$3

`js
// webpack.config.js
module.exports = {
target: 'webworker',
entry: './index.js',
mode: 'production',
node: {
fs: 'empty',
},
module: {
rules: [
{
test: /\.mjs$/,
include: /node_modules/,
type: 'javascript/auto',
},
],
},
performance: {
hints: false,
},
};
`

Just copy and paste built code to cfworker online editor and save.

Or you can use Wrangler, an official CLI tool, so you don't need to copy and paste code manually anymore. But I don't like it due to its inexplicable bugs on Win10.

These codes only need to be run once locally.

`js
const Telegraf = require('telegraf');
const bot = new Telegraf('BOT_TOKEN');

// set webhook
bot.telegram.setWebhook('https://your.cfworker.domain/SECRET_PATH');

// delete webhook
// bot.telegram.deleteWebhook();

// get webhook info
// bot.telegram.getWebhookInfo().then(console.log);
