AI Meets SDLC

Website for the AI meets SDLC seminar, held 13 October 2026 at Marsio Saastamoinen Foundation Stage, Espoo, Finland.

The site is built with Gustwind and HTMLisp, styled with Tailwind CSS, and deployed as a Cloudflare Worker with static assets. The production domain is sdlcai.org.

Requirements

• Node 24 or newer. The repository includes .node-version for Cloudflare Workers Builds and local version managers.
• npm
• Wrangler access to the Cloudflare account for Worker, D1, R2, and Turnstile setup.

Project Structure

• site/layouts/index.html: main page markup and client-side behavior.
• site/tailwind.css: font faces, Tailwind theme variables, and global styles.
• assets/: logo, favicon, fonts, and referenced media.
• worker/index.ts: Cloudflare Worker, interest form endpoint, and scheduled backups.
• migrations/: D1 schema.
• scripts/: local helper scripts for dotenv, backup decryption, and build verification.
• docs/cloudflare.md: Cloudflare provisioning, secrets, backup, and deployment notes.

Development

Install dependencies:

npm install

Run the Gustwind development server:

npm start

Build the static site:

npm run build

Serve the generated build locally:

npm run serve

Format and validate:

npm run format
npm run format:check
npm run validate

Worker Development

Copy .env.example to .env, set a local EMAIL_ENCRYPTION_KEY, then generate Wrangler's .dev.vars:

npm run dev:env

Apply the local D1 migration:

npm run db:migrate:local

Run the Worker locally:

npm run worker:dev

worker:dev builds the site, verifies that build/index.html exists, and then starts Wrangler.

Interest List

The interest form stores submissions in Cloudflare D1. Email, name, and organization are encrypted before insert, and a keyed email hash is stored for deduplication. Plaintext contact details are not stored in D1 or R2.

Scheduled backups export encrypted D1 rows to R2. A latest-backup manifest stores a hash of the encrypted rows so unchanged scheduled runs do not write duplicate backup objects.

Decrypt a downloaded backup with:

EMAIL_ENCRYPTION_KEY=... npm run interests:decrypt -- backup.json

Export contact details for follow-up email from production D1 with:

EMAIL_ENCRYPTION_KEY=... npm run --silent interests:export -- --remote > contacts.csv

The export script also supports local D1 and downloaded backups:

EMAIL_ENCRYPTION_KEY=... npm run --silent interests:export -- --local
EMAIL_ENCRYPTION_KEY=... npm run --silent interests:export -- --input backup.json
EMAIL_ENCRYPTION_KEY=... npm run --silent interests:export -- --remote --format json

Deployment

Deploy through Cloudflare Workers Builds or locally with:

npm run deploy

See Cloudflare setup for provisioning, secrets, backup, and deployment notes.
