Frequently Asked Questions

How does this JavaScript project work?

Built with vanilla JavaScript (no framework) or Vue/Node. HTML structure, CSS styling, JS logic via DOM manipulation + event listeners. Backend optional (Node.js or PHP). Ready to extend for BSIT capstone scope.

What JavaScript runtime or browser does this project need?

Pure frontend projects (vanilla JS, Vue, jQuery) run in any modern browser (Chrome 90+, Firefox 88+, Safari 14+, Edge 90+) – no install needed. Node.js projects need Node.js 18 LTS or 20 LTS (download from nodejs.org). Run: npm install in project folder, then npm start or node app.js.

How do I run this JavaScript project locally?

For pure HTML/CSS/JS: open index.html in your browser, or use VS Code Live Server extension for auto-reload. For Vue projects: npm install then npm run dev (Vite) or npm run serve (Vue CLI). For Node.js: npm install then npm start. For projects with backend (PHP+MySQL): place in XAMPP htdocs, start Apache + MySQL, browse to localhost/project.

Can I use this JavaScript project for a BSIT capstone or thesis?

Yes. Extend it: add user authentication (JWT for SPA, sessions for traditional), role-based access, real backend (Node.js+Express+MongoDB or PHP+MySQL), responsive design (Bootstrap/Tailwind), PDF exports (jsPDF), real-time features (Socket.IO). Pair with Chapter 1-5 documentation matching your panel’s rubric.
