Model Agreement Generator
Type a customer's name, address (village) and date, upload a photo of their signature, and
download the 4-page PM Surya Ghar Model Agreement as a PDF. One shared password protects it.
Nothing is stored: no database, no saved agreements.
Run it on your PC
npm install
npm start
Open http://localhost:3000. The password is the APP_PASSWORD value in the .env file
(copy .env.example to .env and choose one if the file does not exist).
Put it online (Vercel, free)
- Create a free account at vercel.com and install the tool:
npm install -g vercel
- In this folder run
vercel and accept the defaults. It prints a preview link.
- Set the password:
vercel env add APP_PASSWORD production and type the password you want.
- Publish:
vercel --prod. The link it prints is the one to share.
Vercel serves public/ and runs api/generate.js; server.js is only for running on a PC
or on a host such as Render (start command npm start, set APP_PASSWORD there too).
How it works
assets/base.pdf is the agreement already laid out, with the customer's name, address and
dates blanked out. The vendor's stamp and signature are part of it.assets/layout.json records where each blank is.lib/generate.js writes the typed values into those blanks and places the signature
(pdf-lib, Carlito font). About a tenth of a second per agreement; no LibreOffice needed.- The browser cuts the signature out of the uploaded photo (removes the paper background)
and shows a preview before anything is sent.
Changing the agreement wording
The server cannot rebuild the layout. On a PC with LibreOffice and Python (pip install pymupdf):
- Edit
tools/template.docx, keeping the {{...}} placeholders.
- Run
python tools/build-base.py "C:\path\to\soffice.exe".
- Check a generated PDF, then publish again.
Limits
- English letters only in the name and address (the agreement font has no Gujarati).
- Name and address up to 60 characters each; very long ones are shrunk slightly to fit two lines.
- The signature photo should be on plain white paper in good light.
Fonts: Carlito (SIL Open Font License).
