CodeFlow

CodeFlow is an execution-first programming-learning prototype. It explores how program state, output, control flow, and visual feedback can become observable learning primitives instead of treating source code as static text.

Project status: CodeFlow is now treated as a completed/frozen prototype. The repository has been hardened for public inspection and reproducibility; new product development is intentionally out of scope.

🚀 Live prototype

The deployment is experimental and intended for learning and demonstration. It is not a general-purpose programming-language runtime.

Visible State + Feedback

The core principle is execution visibility: learning interactions should expose deterministic state rather than hiding execution behind opaque output.

Experimental AI assistance remains outside the deterministic execution source of truth.

🧪 Final engineering baseline

• Node 22 CI/runtime baseline
• Vite 8 build baseline
• deterministic Node test suite
• production build validation
• tagged release workflow with package-version validation
• automated dependency monitoring through Dependabot
• CodeQL JavaScript analysis
• deployment security headers
• explicit prototype boundary
• architecture documentation
• MIT licensing

CI validates tests and the production build on Node 22. Security analysis runs through GitHub CodeQL.

🔐 Security posture

The hosted prototype is configured with defensive HTTP headers including:

• Strict-Transport-Security
• X-Content-Type-Options
• X-Frame-Options
• Referrer-Policy
• restrictive Permissions-Policy

No credentials or sensitive runtime state belong in the repository.

See SECURITY.md for reporting and scope.

🛠️ Development

npm install
npm test
npm run build
npm run dev

The repository intentionally keeps the development surface small. The prototype is not being expanded into a production interpreter or execution platform.

📦 Release model

Releases use vX.Y.Z tags. The release workflow validates the tag against package.json, runs tests and the production build, and publishes the GitHub release.

See CHANGELOG.md for release history.

🤝 Contributing

Although product development is frozen, maintenance contributions remain welcome when they improve correctness, accessibility, security, reproducibility, documentation, or dependency hygiene.
