Clone repositories and set up development environments in Daytona sandboxes.

Configuration

Copyexport CONVEX_SITE_URL="https://calculating-hummingbird-542.convex.site"

Clone Repository

Copycurl -X POST "$CONVEX_SITE_URL/api/sandbox/git/clone" \
  -H "Content-Type: application/json" \
  -d '{
    "sandboxId": "SANDBOX_ID",
    "repoUrl": "https://github.com/owner/repo.git",
    "branch": "main",
    "targetPath": "/home/user/projects/repo"
  }'

• branch (optional): Branch to checkout (default: default branch)
• targetPath (optional): Clone destination (default: /home/daytona/projects/{repo-name})

Returns: {"success": true, "path": "/home/daytona/projects/repo", "output": "..."}

Complete Development Setup Workflow

1. Clone the Repository

Copycurl -X POST "$CONVEX_SITE_URL/api/sandbox/git/clone" \
  -H "Content-Type: application/json" \
  -d '{"sandboxId": "abc123", "repoUrl": "https://github.com/BraelinC/planner"}'

2. Check Repository Structure

Copycurl -X POST "$CONVEX_SITE_URL/api/sandbox/execute" \
  -H "Content-Type: application/json" \
  -d '{"sandboxId": "abc123", "command": "ls -la /home/daytona/projects/planner"}'

3. Install Dependencies

For Node.js projects:

Copycurl -X POST "$CONVEX_SITE_URL/api/sandbox/execute" \
  -H "Content-Type: application/json" \
  -d '{"sandboxId": "abc123", "command": "cd /home/daytona/projects/planner && npm install", "timeout": 120}'

For Python projects:

Copycurl -X POST "$CONVEX_SITE_URL/api/sandbox/execute" \
  -H "Content-Type: application/json" \
  -d '{"sandboxId": "abc123", "command": "cd /home/daytona/projects/planner && pip install -r requirements.txt", "timeout": 120}'

4. Start Development Server

Run in background:

Copycurl -X POST "$CONVEX_SITE_URL/api/sandbox/execute" \
  -H "Content-Type: application/json" \
  -d '{"sandboxId": "abc123", "command": "cd /home/daytona/projects/planner && npm run dev &"}'

5. Open Browser to View App

Option A: Use terminal to open browser

Copycurl -X POST "$CONVEX_SITE_URL/api/sandbox/execute" \
  -H "Content-Type: application/json" \
  -d '{"sandboxId": "abc123", "command": "firefox http://localhost:3000 &"}'

Option B: Click on browser icon in taskbar First take screenshot to see the desktop, then click on browser icon.

6. Take Screenshot to Verify

Copycurl -X POST "$CONVEX_SITE_URL/api/sandbox/screenshot" \
  -H "Content-Type: application/json" \
  -d '{"sandboxId": "abc123", "compressed": true, "quality": 80}'

Common Project Types

Next.js / React

Copy# Install
npm install
# Dev server
npm run dev
# Default port: 3000

Vite

Copy# Install
npm install
# Dev server
npm run dev
# Default port: 5173

Python Flask/Django

Copy# Install
pip install -r requirements.txt
# Flask
flask run
# Django
python manage.py runserver
# Default port: 5000 (Flask) or 8000 (Django)

Editing Code

Read a file

Copycurl -X POST "$CONVEX_SITE_URL/api/sandbox/fs/read" \
  -H "Content-Type: application/json" \
  -d '{"sandboxId": "abc123", "path": "/home/daytona/projects/planner/src/App.tsx"}'

Write changes

Copycurl -X POST "$CONVEX_SITE_URL/api/sandbox/fs/write" \
  -H "Content-Type: application/json" \
  -d '{"sandboxId": "abc123", "path": "/home/daytona/projects/planner/src/App.tsx", "content": "..."}'

Hot reload

Most dev servers auto-reload on file changes. Take a screenshot to verify.

Tips

• Clone timeout is 120 seconds by default for large repos
• Public repos work without authentication
• Check package.json or requirements.txt to understand the project
• Use cat package.json to see available npm scripts
• Start dev servers with & to run in background
• Take screenshots after starting server to verify it's running

Known Constraints

⚠️ CONSTRAINT: Default sandbox has only 1GB RAM - large npm/bun installs will be killed (OOM).

• Monorepos with many dependencies need 2-4GB RAM
• Install bun via npm: npm install -g bun

⚠️ CONSTRAINT: The sandbox user is daytona, not user.

• Clone to /home/daytona/projects/ not /home/user/projects/

⚠️ CONSTRAINT: Tier 1-2 sandboxes cannot curl arbitrary URLs.

• Connection reset errors for non-whitelisted domains
• npm/pip registries work fine

✅ BEST PRACTICE: For workspace:* dependencies, use bun or pnpm (npm doesn't support workspace protocol).
