{"id":14096,"library":"talkjs","title":"TalkJS Classic JavaScript SDK","description":"TalkJS Classic JavaScript SDK (currently v0.45.1) is a client-side library designed to integrate real-time chat functionality into web applications with minimal effort. It provides a pre-built, highly customizable UI for common messaging patterns like user-to-user and group chats, distinguishing itself by offering a complete chat experience out-of-the-box rather than just an API. The library ships with comprehensive TypeScript type definitions, enhancing developer experience. While the core TalkJS library is loaded asynchronously from a CDN, this package simplifies its injection into modern front-end build chains. The project emphasizes strong backward compatibility, with new features and fixes released regularly, though specific cadence is not published. It's strictly for browser environments; separate packages exist for React Native and Expo.","status":"active","version":"0.45.1","language":"javascript","source_language":"en","source_url":null,"tags":["javascript","chat","chat api","chat sdk","messaging","talk","talkjs","real-time messaging","real-time chat","typescript"],"install":[{"cmd":"npm install talkjs","lang":"bash","label":"npm"},{"cmd":"yarn add talkjs","lang":"bash","label":"yarn"},{"cmd":"pnpm add talkjs","lang":"bash","label":"pnpm"}],"dependencies":[],"imports":[{"note":"Standard ESM import for client-side applications.
