Javascript Compiler

💾 How does autosave work in JSCompiler?

JSCompiler auto-saves edits and project names to your browser’s localStorage; click Save (or press Ctrl/Cmd+S) to store a permanent copy in our database with a shareable URL and cross-device access. localStorage is browser-specific, so save to the database to use the project on another device or browser.

🤝 Can I collaborate with others in real-time?

No. There’s no real-time collaboration; you can share a URL for others to view/run, they can fork to make their own copy, and you can collaborate by sharing forks back and forth sequentially.

🔗 How do I share my code with others?

Save your project to the database, click Share to get a unique URL, then copy and send it. All projects are public—don’t include sensitive information.

🧩 What JavaScript features and versions are supported?

Runs modern ES6+ JavaScript with full Web API access and console methods. Limitations: no Node.js APIs, no installing or importing npm packages, and execution is client-side only.

📦 Can I install and use npm packages?

Partially. You can search npm packages and mark interest, but nothing is actually installed. To use libraries, include browser-compatible ones via a CDN script URL; Node-only packages won’t work.

🍴 How does forking work?

Forking creates an independent copy of a project, appends “(Fork)” to its name, and keeps a reference to the original. Changes in your fork don’t affect the source.

🔒 Is my code private?

No. All projects are public; anyone with a link can view and fork, and database-saved projects may be discoverable. Never store secrets or credentials.

⚠️ What happens if I don't save my project?

Unsaved work persists via localStorage in the same browser on the same device; loading a shared URL replaces your draft, and clearing browser data deletes it. Click Save for a permanent, shareable copy.

⏱️ Are there any execution limits or timeouts?

No explicit limits, but browser constraints apply: long tasks may freeze tabs, high memory can crash, and infinite loops will hang. Keep code lightweight and prefer logging over heavy loops.

🌐 Which browsers are supported?

Best on modern browsers: Chrome 90+, Edge 90+, Firefox 88+, Safari 14+. Requires ES6+, localStorage, and fetch. The IDE is desktop-optimized; mobile may be limited.

💻 How does the integrated terminal work?

The terminal is UI-only with basic commands (help, clear, version). It’s not a real shell and can’t run system, file, or npm commands; it’s for display and future expansion.

💼 Can I use JSCompiler for commercial projects?

Yes. Free for personal, educational, and commercial use with no account required. Attribution is appreciated, but avoid proprietary or sensitive code since projects are public.
