Problem

The NewsletterSignup component shows "coming soon" on every page.

Revised approach

Self-host email capture instead of Buttondown. Keep it minimal:

  1. Add a local JSON file or SQLite table to store emails
  2. Create a lightweight POST endpoint on the preview server to accept signups
  3. Store emails locally for batch export when ready to send
  4. No external service dependency

Why

  • Zero monthly cost, full control over subscriber data
  • Frontend component is already built - just needs a backend to receive the data
  • Can ship to any email service later

Implementation

POST /api/newsletter
Body: { "email": "user@example.com" }
Stores to /data/subscribers.json
Returns 201

Priority

HIGH - the component is built, the missing piece is a POST endpoint.

Status

REVISED: self-hosted capture, not Buttondown.

Added POST /api/subscribe endpoint to preview-serve.ts. Validates email format, stores unique subscribers in site/data/subscribers.json. Returns 200 on success, 409 for duplicates, 400 for invalid input. Commit 81140de.
