Minimal Vercel serverless function that renders pages of my-resume to PDF using headless Chromium.

GET /api/pdf?url=<encoded url>&format=A4&landscape=0

The target URL is filtered against an allowlist of hostnames. Only http/https URLs are accepted.

Comma-separated list of allowed hostnames. Configure it in Vercel → Project → Settings → Environment Variables.

ALLOWED_HOSTS=elzinko.fr,www.elzinko.fr,elzinko.github.io,localhost,127.0.0.1

Wildcards are supported as a leading label: *.example.com matches sub.example.com but not example.com itself. The protocol is always restricted to http/https regardless of the allowlist.

If ALLOWED_HOSTS is unset, falls back to a hardcoded safe default (elzinko.fr, www.elzinko.fr, elzinko.github.io, localhost, 127.0.0.1). Adding a new hostname after a domain change should not require a redeploy of the code — just update the env var and Vercel re-runs the function with the new value.

1. Go to https://vercel.com/new and import this repo (elzinko/my-resume-api).
2. Framework preset: Other.
3. (Optional) Set the ALLOWED_HOSTS env var to override the default allowlist.
4. Click Deploy. Vercel installs @sparticuz/chromium + puppeteer-core automatically.
5. The function URL will look like https://my-resume-api.vercel.app/api/pdf.

curl -o resume.pdf 'https://my-resume-api.vercel.app/api/pdf?url=https%3A%2F%2Felzinko.github.io%2Fmy-resume%2Ffr'
open resume.pdf

job-app calls this endpoint from /api/offres/:id/cv-pdf-generate and stores the resulting PDF in public/cvs/cv-{hash}.pdf.
