Data Flow

1. User builds app using visual drag-and-drop interface
2. Components bind to data sources via queries
3. Queries execute against connected databases/APIs
4. Results render in UI components
5. User actions trigger JavaScript/Python handlers
6. Real-time updates via WebSocket connections
7. Changes persisted to ToolJet application database

Installation and Usage

Quick Start with Docker

docker run \
  --name tooljet \
  --restart unless-stopped \
  -p 80:80 \
  --platform linux/amd64 \
  -v tooljet_data:/var/lib/postgresql/13/main \
  tooljet/try:ee-lts-latest

Docker Compose (Production)

version: "3"
services:
  tooljet:
    image: tooljet/tooljet-ce:ce-lts-latest
    restart: always
    ports:
      - "80:80"
    environment:
      - TOOLJET_HOST=https://your-domain.com
      - PG_HOST=postgres
      - PG_DB=tooljet
      - PG_USER=postgres
      - PG_PASS=password
      - SECRET_KEY_BASE=your-secret-key
    depends_on:
      - postgres
  postgres:
    image: postgres:13
    environment:
      - POSTGRES_USER=postgres
      - POSTGRES_PASSWORD=password
      - POSTGRES_DB=tooljet
    volumes:
      - postgres_data:/var/lib/postgresql/data
volumes:
  postgres_data:

Creating a Data Source Connection

1. Navigate to Data Sources page from dashboard sidebar
2. Select category (Databases, APIs, Cloud Storage, Plugins)
3. Click + Add on desired data source
4. Enter connection configuration
5. Data source available across workspace applications

Building an Application

1. Create new app from dashboard
2. Drag components from component library
3. Add queries to connect data sources
4. Bind query results to component properties
5. Add JavaScript event handlers for interactivity
6. Deploy application

CLI Tool

The ToolJet CLI enables custom plugin development:

# Install CLI
npm install -g @tooljet/cli

# Create new plugin
tooljet plugin create my-data-source

# Build plugin
tooljet plugin build

# Publish to marketplace
tooljet plugin publish

Relevance to Claude Code Development

Direct Applications

1. Internal Tool Building: Rapid prototyping of dashboards and admin interfaces that could complement Claude Code workflows.

2. Agent Builder Patterns: ToolJet's AI Agent Builder demonstrates visual approaches to workflow automation that could inform skill design.

3. Data Source Integration: The 75+ connector patterns provide reference implementations for database and API integrations.

4. Plugin Architecture: The CLI-based plugin creation workflow offers patterns for extensible tool ecosystems.

5. Multi-Tenant Security: RBAC, row-level security, and audit logging patterns applicable to enterprise Claude Code deployments.

Patterns Worth Adopting

1. Visual Query Building: Natural language to SQL/query translation reduces barrier for non-developers.

2. Component Library: Well-organized, discoverable component system with consistent APIs.

3. Workspace Scoping: Data sources shared at workspace level, similar to skill sharing patterns.

4. Multi-environment Support: Dev/staging/production environment management for controlled deployments.

5. Plugin Marketplace: Extensibility through community-contributed connectors.

Integration Opportunities

1. MCP Server for ToolJet: Expose ToolJet applications as MCP tools for Claude Code workflows.

2. Claude-Powered Agents: Use Claude models within ToolJet Agent Builder for intelligent automation.

3. Data Pipeline Integration: ToolJet as data visualization layer for Claude Code analysis outputs.

4. Admin Interface Generation: Generate ToolJet admin UIs for Claude Code project management.

5. Workflow Handoff: ToolJet workflows could trigger or be triggered by Claude Code processes.
