Code Canvas Complete — Online IDE

Overview

Code Canvas Complete is a feature-rich browser-based online IDE built with React, Vite, TypeScript, and Tailwind CSS. It supports multi-language code execution (via Wandbox), AI chat assistance, Arduino/FTC breadboard simulation, collaborative editing, 3D model generation, and much more.

Architecture

Frontend Only

This project is a pure frontend application — there is no custom backend server. All data persistence and auth is handled by an external Supabase project.

  • Framework: React 18 + Vite 5
  • Styling: Tailwind CSS + shadcn/ui (Radix UI)
  • Auth & Database: Supabase (xlmvlplazxrouscupidi)
  • Edge Functions: Supabase Edge Functions (Deno) in supabase/functions/
  • State Management: React Query (@tanstack/react-query)
  • Routing: React Router v6

Key Integrations

  • src/integrations/supabase/ — Supabase client and TypeScript types
  • src/integrations/auth/ — Auth provider abstraction (Supabase/Lovable/Replit)
  • src/integrations/ai/ — AI provider abstraction for chat, image, music
  • src/integrations/datalovable/ — Lovable-specific data layer

Platform Detection

src/lib/platform.ts detects the deployment platform (replit/lovable/generic) based on the hostname or VITE_DEPLOY_PLATFORM env var. On Replit, it automatically uses Replit-specific auth flows.

Development

Running

npm run dev

Runs on port 5000 (required by Replit webview).

Building

npm run build

Testing

npm test

Environment Variables

These are set as Replit environment variables:

Variable Description
VITE_SUPABASE_URL Supabase project URL
VITE_SUPABASE_PUBLISHABLE_KEY Supabase anon/publishable key
VITE_SUPABASE_PROJECT_ID Supabase project ID

Supabase Edge Functions

Located in supabase/functions/, these are Deno-based edge functions deployed to Supabase:

  • ai-chat — Main AI chat completions
  • generate-command — AI shell command generation
  • generate-music — Music generation via Lyria
  • generate-image — Image generation
  • compile-arduino — Arduino sketch compilation via Godbolt
  • compile-ftc — FTC Java/Kotlin compilation
  • execute-code — Code execution via Wandbox
  • github-proxy — GitHub API proxy
  • manage-env-secrets — Project environment secrets
  • session-recorder-sync — Session recording persistence
  • And more...

Notable Features

  • Multi-language code execution (JS, TS, Python, Java, C++, Go, Rust, and 30+ more)
  • Arduino IDE with breadboard circuit designer and simulation
  • FTC (FIRST Tech Challenge) robot programming
  • AI coding assistant with file-aware context
  • Real-time collaboration
  • Extension marketplace
  • Team management
  • 3D model generation (Meshy, Tripo, Fal.ai, etc.)
  • Image and music generation
  • Office document editing (Word, Excel, PowerPoint)
  • Scratch visual programming
  • CAD model viewer
  • Git integration

Replit Migration Notes

  • Vite dev server configured on port 5000 with host: "0.0.0.0" and allowedHosts: true
  • Supabase credentials stored as Replit env vars (not in .env)
  • .env added to .gitignore
  • The app uses the existing external Supabase project for all backend functionality
