AJ Takeoff

Commercial electrical takeoff for AJ Electrical: upload up to 120 plan pages, name sheets, zoom into corners, set the drawing scale, measure, draw linear-foot runs, and count fixtures and devices with engineer's descriptions.

It's a single static page (index.html), with no build step. Vercel serves it as-is.

When it's opened as the website, every job saves online in Vercel Blob a few seconds after each change (api/jobs, api/team-upload), so everyone using the app sees the same jobs. The browser keeps its own copy too. Google Drive saving works when the app is opened inside Claude.

A Google Apps Script (drive-backup/AJ-Takeoff-daily-backup.gs) copies the app, the Bid tracker, every job and every plan sheet into the shared drive each night.

Live site updates automatically from this repo through Vercel (project aj-commercial-takeoff).

Live app: https://aj-commercial-takeoff.vercel.app

Sign-in and the Admin page (v116)

• Add SESSION_SECRET in Vercel (any long random text) and redeploy. After that everyone signs in on /login.html with their own name and password.
• People, their access (Admin / Office / Field), password resets and turning someone off are on the app's Admin button (admins only). The first person added is always an Admin. Passwords are saved only as PBKDF2 hashes in Blob (team/admin/users-*.json).
• Company details, labor hours, parts lists, standard exclusions and vendor lists are shared through api/settings (team/admin/settings-*.json).
• APP_PASSWORD (admin) and FIELD_PASSWORD (field) still work as shared logins if set. The Drive backup script uses the backup key from the Admin page as its APP_PASSWORD Script property.
• Without SESSION_SECRET the site works the old way (browser password box, or open if APP_PASSWORD isn't set).
• sw.js keeps the app on the device so it opens without internet. Changes made offline stay on the device and are saved online after a "You're back online" prompt.
