{"id":17992,"library":"utils-mf","title":"WhatsApp Bot Utilities for Baileys","description":"This library, `utils-mf`, provides a collection of helper functions designed to streamline the development of WhatsApp bots using the `@adiwajshing/baileys` package. It abstracts away common tasks such as initializing the WhatsApp client, handling media (sending and downloading), message serialization, querying group information, and retrieving contact details. Additionally, it offers various general-purpose utilities like URL validation, time formatting, and random number generation, and its keywords suggest integration for TikTok media downloading. Currently at version `10.10.2`, the package appears to be actively maintained, indicated by a healthy release cadence. It is primarily distributed as a CommonJS module. Its main value lies in offering a convenient toolkit for developers working with the unofficial WhatsApp Web API via Baileys, aiming to simplify complex bot functionalities.","status":"active","version":"10.10.2","language":"javascript","source_language":"en","source_url":null,"tags":["javascript","whatsapp","baileys","js-whatsapp","whatsapp-api","whatsapp-web","whatsapp-chat","whatsapp-group"],"install":[{"cmd":"npm install utils-mf","lang":"bash","label":"npm"},{"cmd":"yarn add utils-mf","lang":"bash","label":"yarn"},{"cmd":"pnpm add utils-mf","lang":"bash","label":"pnpm"}],"dependencies":[{"reason":"Core library for WhatsApp Web API interaction","package":"@adiwajshing/baileys","optional":false}],"imports":[{"note":"This package is a CommonJS module; direct ES module `import` statements will cause runtime errors in Node.js environments unless transpiled or using dynamic `import()`.","wrong":"import { start } from 'utils-mf';","symbol":"start, sendMedia","correct":"const { start, sendMedia } = require('utils-mf');"},{"note":"Destructuring assignment is the idiomatic way to import multiple named exports from a CommonJS module.","wrong":"const download = require('utils-mf').downloadMedia;","symbol":"downloadMedia, serialize","correct":"const { downloadMedia, serialize } = require('utils-mf');"},{"note":"Provides an object containing all exported utility functions.
