How this project works
Wavelength Commons is the SvelteKit remake of Westloop: a neighborhood social network with accounts, profiles, follows, likes, comments, a following timeline, search, notices, and a real Ubuntu VPS deploy. Each numbered folder in fcc-sveltekit-social is a working snapshot.
The stack, and why these tools
| Job | Choice | Why |
|---|---|---|
| Language / framework | TypeScript, SvelteKit | SvelteKit form actions are progressive enhancement. Prisma + Postgres on `adapter-node` is the VPS path — not only Cloudflare. |
| Database | PostgreSQL | Follows, likes, and comments need foreign keys and unique pairs. SQLite is only for the first laptop boot. |
| CSS | Tailwind CSS | Feeds, avatars, and a sticky nav are layout-heavy. Utilities stay in the templates you already edit. |
| JavaScript | SvelteKit form actions + Alpine.js | Use actions for follow/like. The form works with JS disabled. Alpine is optional. |
| Authentication | Cookie sessions + bcrypt | Signed cookies via hooks. Avoid Supabase-only auth here so the VPS owns the users table. |
| Process / proxy | Node adapter + systemd, Nginx, Let’s Encrypt | Same VPS shape as Westloop: one app process, Postgres on localhost, Nginx for TLS and static/media files. |
| Hosting / DNS | Hetzner Cloud CX22 (or Contabo / DigitalOcean), Cloudflare Registrar + DNS | You own the box. PaaS is easier and teaches less. |
| Console locally, Postmark in production | Password reset must leave the laptop. |
If you already finished the SvelteKit blog, keep going — this project adds a social graph and a VPS ship, not another CRUD journal.
