Project Overview

GROWI is a team collaboration software using markdown - a wiki platform with hierarchical page organization. It's built with Next.js, Express, MongoDB, and includes features like real-time collaborative editing, authentication integrations, and plugin support.

Development Commands

Core Development

  • turbo run bootstrap - Install dependencies for all workspace packages
  • turbo run dev - Start development server (automatically runs migrations and pre-builds styles)

Production Commands

  • pnpm run app:build - Build GROWI app client and server for production
  • pnpm run app:server - Launch GROWI app server in production mode
  • pnpm start - Build and start the application (runs both build and server commands)

Database Migrations

  • pnpm run migrate - Run MongoDB migrations (production)
  • turbo run dev:migrate @apps/app - Run migrations in development (or wait for automatic execution with dev)
  • cd apps/app && pnpm run dev:migrate:status - Check migration status
  • cd apps/app && pnpm run dev:migrate:down - Rollback last migration

Testing and Quality

  • turbo run test @apps/app - Run Jest and Vitest test suites with coverage
  • turbo run lint @apps/app - Run all linters (TypeScript, ESLint, Biome, Stylelint, OpenAPI)
  • cd apps/app && pnpm run lint:typecheck - TypeScript type checking only
  • cd apps/app && pnpm run test:vitest - Run Vitest unit tests
  • cd apps/app && pnpm run test:jest - Run Jest integration tests

Development Utilities

  • cd apps/app && pnpm run repl - Start Node.js REPL with application context loaded
  • turbo run pre:styles @apps/app - Pre-build styles with Vite

Architecture Overview

Monorepo Structure

  • /apps/app/ - Main GROWI application (Next.js frontend + Express backend)
  • /apps/pdf-converter/ - PDF conversion microservice
  • /apps/slackbot-proxy/ - Slack integration proxy service
  • /packages/ - Shared libraries and components

Main Application (/apps/app/src/)

  • client/ - Client-side React components and utilities
  • server/ - Express.js backend (API routes, models, services)
  • components/ - Shared React components and layouts
  • pages/ - Next.js page components using file-based routing
  • stores/ - State management (SWR-based stores with React context)
  • styles/ - SCSS stylesheets with modular architecture
  • migrations/ - MongoDB database migration scripts
  • interfaces/ - TypeScript type definitions

Key Technical Details

  • Frontend: Next.js 14 with React 18, TypeScript, SCSS modules
  • Backend: Express.js with TypeScript, MongoDB with Mongoose
  • State Management: SWR for server state, React Context for client state
  • Authentication: Passport.js with multiple strategies (local, LDAP, OAuth, SAML)
  • Real-time Features: Socket.io for collaborative editing and notifications
  • Editor: Custom markdown editor with collaborative editing using Yjs
  • Database: MongoDB 8.0+ with migration system using migrate-mongo
  • Package Manager: pnpm with workspace support
  • Build System: Turborepo for monorepo orchestration

Development Dependencies

  • Node.js v20.x or v22.x
  • pnpm 10.x
  • MongoDB v6.x or v8.x
  • Optional: Redis 3.x, Elasticsearch 7.x/8.x/9.x (for full-text search)

File Organization Patterns

Components

  • Use TypeScript (.tsx) for React components
  • Co-locate styles as .module.scss files
  • Export components through index.ts files where appropriate
  • Group related components in feature-based directories

API Structure

  • Server routes in server/routes/
  • API v3 endpoints follow OpenAPI specification
  • Models in server/models/ using Mongoose schemas
  • Services in server/service/ for business logic

State Management

  • Use SWR hooks in stores/ for server state
  • Custom hooks pattern for complex state logic
  • Context providers in stores-universal/ for app-wide state

When working with this codebase, always run the appropriate linting and testing commands before committing changes. The application uses strict TypeScript checking and comprehensive test coverage requirements.
