# Project Overview

Chatwoot is an open-source customer engagement platform that helps businesses manage customer conversations across multiple channels (email, website live chat, WhatsApp, Twitter, etc.) in a unified inbox. It is designed for support teams, sales teams, and businesses looking to provide excellent customer service while maintaining control over their data.

## Quick Facts

  - JavaScript/Vue (1007 `.vue` files, 988 `.js` files) – Frontend framework
  - JSON (2471 files) – Configuration and data
  - Other: no-extension (8796 files) – Likely includes logs, build artifacts, or miscellaneous files

## File Structure & Code Organization

- `Rakefile` – Custom Rake tasks.
- `Makefile` – Build automation scripts.
- `tailwind.config.js`, `postcss.config.js`, `vite.config.ts` – Frontend build and styling tooling.
- `README.md`, `CONTRIBUTING.md`, `CODE_OF_CONDUCT.md`, `SECURITY.md` – Project documentation and governance.
- `LICENSE` – Project licensing information.
- `Procfile`, `Procfile.dev`, `Procfile.test`, `Procfile.tunnel` – Process management for Heroku and local development.

## Technology Stack Summary
- **Backend**: Ruby on Rails (MVC architecture)
- **Frontend**: Vue.js (with Vite for bundling)
- **Database**: PostgreSQL (primary), Redis (caching/sidekiq)
- **Testing**: RSpec (backend), Jest/Vitest (frontend)
- **Styling**: Tailwind CSS (utility-first CSS framework)
- **Build Tools**: Vite, esbuild, pnpm (package manager)
- **Deployment**: Docker, Clever Cloud, Heroku
- **CI/CD**: GitHub Actions (likely, based on standard Rails/Vue setups)

## Core Framework Stack
- **Backend**: Ruby on Rails (handles API, business logic, and database interactions)
- **Frontend**: Vue 3 (composition API, single-file components)
- **Real-time**: Action Cable (WebSockets for live chat)
- **Background Jobs**: Sidekiq (Redis-backed async processing)
- **Authentication**: Devise (with custom extensions for multi-tenancy)

## UI & Interaction Libraries
- **UI Kit**: Custom Vue components with Tailwind CSS styling
- **Design System**: Follows accessibility best practices (WCAG) and supports theming
- **Localization**: Crowdin integration for multi-language support
- **CLI Tools**: Custom Rake tasks and scripts for administration

## Development Tools Overview
- **CLI**: `bin/rails`, `bin/rake`, `npm run dev`
- **Scripts**: `script/` directory for common workflows (e.g., `script/setup`)
- **Debugging**: `debug_auth.rb`, `debug_jasmine_tool.rb` for testing
- **Linting**: RuboCop (Ruby), ESLint (JavaScript)
