KLEF ERP — attendance & academic calendar (frontend)

Static site: no build step, no server code. It talks to the private backend (KLEF-ERP-Backend) over HTTPS.

Page	What it shows
index.html	KL ERP login (captcha shown with the code pre-filled) → attendance report with the academic calendar overlaid
calendar.html	2026-27 academic calendar: class days, holidays, exam days, upcoming events, your own projection
admin.html	Password-protected stats for every student, plus feedback

Every page has a 💬 Feedback button.

Configure

Set the backend URL in js/config.js (BACKEND). On localhost the pages call http://localhost:3000 instead. The backend must list this site's origin in its ALLOWED_ORIGINS.

Host

Any static host works:

• Vercel: import this repo, Framework preset "Other", no build command. vercel.json turns on clean URLs (/calendar, /admin).
• GitHub Pages: Settings → Pages → deploy from main / root. All paths are relative, so a /KLEF-ERP/ subpath is fine.

Run locally

npx serve -l 5173 .     # with the backend running on :3000

Files

• js/academic-calendar.js: the 2026-27 calendar data and maths (a copy also lives in the backend).
• The captcha comes pre-filled: the backend reads it and returns its guess with the image (the student still sees both).
• js/feedback.js: feedback widget.
