About

This is the frontend of my portfolio website.

See more here.

Environment

Copy .env.example to .env.local and fill in the values. The contact form (/api/email) needs the SMTP variables; reCAPTCHA v3 is optional and fail-open (the form works without it).

Variable	Purpose
EMAIL_HOST / EMAIL_USER / EMAIL_PASS	SMTP transport for the contact form
FROM_EMAIL / TO_EMAIL	Sender + recipient for contact submissions
NEXT_PUBLIC_RECAPTCHA_SITE_KEY	reCAPTCHA v3 public site key (client)
RECAPTCHA_SECRET_KEY	reCAPTCHA v3 secret key (server verification)
BEHANCE_API_KEY	Behance API for the "Digital Art" page

reCAPTCHA v3 (contact form)

1. Create keys at https://www.google.com/recaptcha/admin/create — type reCAPTCHA v3, domains zack.land, www.zack.land, localhost.
2. Set NEXT_PUBLIC_RECAPTCHA_SITE_KEY and RECAPTCHA_SECRET_KEY (locally and in Vercel).
3. In production, redeploy after adding them so the public site key is inlined into the client bundle.

When the secret is unset, submissions skip verification; when set, a submission must clear a 0.5 score threshold on the contact action. Verification logic is unit-tested — run npm test.
