## What it is
Talk OS is the open-source version of jianliao.com, a team chat/messaging application written in CoffeeScript on Node.js. It bundles the full business code of the product, using MongoDB, Redis, and optional Elasticsearch for message search.

## Use cases
- self-host a team chat application
- study the source code of a production chat product
- build a custom Slack-like messenger
- run an internal messaging server with MongoDB and Redis
- learn how a real-time chat app is architected

## When to choose
- you want a self-hosted team chat platform you can freely modify
- you need reference code for building real-time messaging features
- your stack is Node.js/CoffeeScript with MongoDB and Redis

## When to avoid
- you need a maintained, secure chat solution (last release 2017, Node 4 era)
- you want modern tooling or TypeScript
- you require message search without manual re-enabling of Elasticsearch integration

## Facets
- artifact type: application
- maturity: abandoned
- function: chat-interface, http-server, search-engine, caching, websocket
- domain: messaging-platforms, web-development, self-hosted
- platform: self-hosted
