Decision Log
Use Next.js App Router with Server Components
Simplifies data fetching (server-only clients) and reduces client bundle size; server actions allow safe server‑side writes without building separate REST endpoints.
Trade-off: Tight coupling to Next.js App Router and canary features (future breaking changes possible); reduces portability to non-Next runtimes.
Use Sanity as headless CMS and store authors in CMS
Fast iteration for editorial UX and built-in content APIs; NextStudio simplified embedding.
Trade-off: External dependency and rate limits; dependence on Sanity write token for mutations (server-only secret) introduces single point of failure if token is missing.
Server-only write client with token validation
Protects write operations to server-only contexts and avoids accidental client writes.
Trade-off: Build or startup fails early if env is missing; requires secure secret management in deployment.
Architecture Narrative
Challenge
Provides a lightweight platform to publish short startup pitches, discover and browse pitches by category or search, and increment content views while retaining an editorial experience via an embedded Sanity Studio.
Solution
Monolithic server-side rendered web application (single Next.js application) augmented by a headless CMS (Sanity) and external services (GitHub OAuth, Sentry). The app uses Server Components + Client Components and Server Actions (Next.js App Router patterns).
Result
Key measurable signals: avg_server_response_ms (40-800 ms (warm-cold range)), estimated_throughput_rps (50-200 rps (depends on hosting and Sanity quotas)), error_rate (<1% (expected under normal load)).
Trade-off Matrix
| Dimension | Selected Option | Impact | Compromise |
|---|---|---|---|
| Rendering model | Server Components + SSR with Server Actions | Small client bundles, secure server-side mutation paths, consistent SEO-friendly HTML | Dependent on Next.js App Router canary features; more complex debugging and ties to Vercel/serverless model |
| Content storage | Sanity (SaaS headless CMS) | Fast editorial iteration, built-in Studio and live preview, GROQ queries | External service dependency, rate limits, cost per write; write token must be protected and managed carefully |
What I'd Do Differently
+
Sanitize markdown and restrict allowed HTML/SVG: Replace raw markdown-it -> markdown-it + strict sanitizer (DOMPurify or sanitize-html) and remove dangerouslyAllowSVG: true unless strictly required.
+
Add resilient write patterns: implement idempotency keys for form submissions, add retry with exponential backoff for write operations, and change view counting to buffered/aggregate updates to avoid per-render writes.
