Title: Boundary Demo (10–15 min) — Batteries included, boundaries enforced

Audience

• Clojure teams building internal tools/SaaS backends
• Goal: show speed + structure (FC/IS), security (MFA), SSR/HTMX, and observability

Prereqs (on screen briefly)

• Java 17+, Clojure CLI installed
• Repo cloned: https://github.com/thijs-creemers/boundary-starter
• Env: BND_ENV=development, JWT_SECRET set

Structure

• 00:00–01:00 — Hook & value prop
• 01:00–04:00 — Run starter, tour architecture (FC/IS)
• 04:00–09:00 — Scaffold a module, migrate, admin UI in action
• 09:00–12:00 — MFA enable/login flow
• 12:00–14:00 — Observability and error handling
• 14:00–15:00 — Build/deploy + recap

Script

00:00–01:00 — Hook & value prop

• "Boundary helps teams ship secure, observable Clojure apps fast — with clean architecture and no frontend build step. Batteries included, boundaries enforced."
• Show README tagline + quickstart briefly.

01:00–04:00 — Run starter, tour architecture

• Terminal: clojure -M:repl-clj, in REPL: (require '[integrant.repl :as ig-repl]) (ig-repl/go)
• Browser: open http://localhost:3000 (home page)
• Explain module layout: src/boundary/{module}/core/, shell/, ports.clj, schema.clj
• Reinforce FC/IS: core = pure; shell = I/O/validation/adapters; ports = protocols.

04:00–09:00 — Scaffold a module

• Terminal: scaffold
  • clojure -M -m boundary.scaffolder.shell.cli-entry generate \
  • --module-name product \
  • --entity Product \
  • --field name:string:required \
  • --field sku:string:required:unique \
  • --field price:decimal:required
• Terminal: clojure -M:migrate up
• REPL: (ig-repl/reset)
• Browser: Admin UI → products listed, create/edit/delete
• Call out validation: Malli schemas, snapshot tests; show clojure -M:test:db/h2 --focus-meta :unit

09:00–12:00 — MFA enable/login

• Terminal: setup + enable
  • curl -X POST http://localhost:3000/api/auth/mfa/setup -H "Authorization: Bearer <token>"
  • curl -X POST http://localhost:3000/api/auth/mfa/enable -H "Authorization: Bearer <token>" -d '{"secret":"...","verificationCode":"123456"}'
• Terminal: login with MFA
  • curl -X POST http://localhost:3000/api/auth/login -d '{"email":"user@example.com","password":"...","mfa-code":"123456"}'
• Explain where teams enforce MFA, and that it’s production‑ready out of the box.

12:00–14:00 — Observability

• Explain interceptor pattern: service/persistence operations wrap logging/metrics/error reporting.
• Show a simple service call and a typed error propagating with an operation name.
• Mention providers: dev no‑op, Datadog, Sentry plug‑ins; swap per env without code churn.

14:00–15:00 — Build/deploy + recap

• Terminal: clojure -T:build clean && clojure -T:build uber then java -jar target/boundary-*.jar server
• Optional Dockerfile snippet
• Recap: "Batteries included, boundaries enforced — FC/IS, SSR/HTMX, admin + MFA, and observability ready from day one."

Recording tips

• Keep terminal font large, dark theme.
• Pre‑seed a JWT token or mock for MFA.
• Use two browser windows: app and admin.
• Have migrations and scaffolder ready to avoid delays.
