Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
## When to Use API Routes Use API routes when you need: - **Server-side secrets** — API keys, database credentials, or tokens that must never reach the client - **Database operations** — Direct database queries that shouldn't be exposed - **Third-party API proxies** — Hide API keys when calling external services (OpenAI, Stripe, etc.) - **Server-side validation** — Validate data before database writes - **Webhook endpoints** — Receive callbacks from services like Stripe or GitHub - **Rate limiting** — Control access at the server level - **Heavy computation** — Offload processing that would be slow on mobile ## When NOT to Use API Routes Avoid API routes when: - **Data is already public** — Use direct fetch to public APIs instead - **No secrets required** — Static data or client-safe operations - **Real-time updates needed** — Use WebSockets or services like Supabase Realtime - **Simple CRUD** — Consider Firebase, Supabase, or Convex for managed backends - **File uploads** — Use direct-to-storage uploads (S3 presigned URLs, Cloudflare R2) - **Authentication only** — Use Clerk, Auth0, or Firebase Auth instead ## File Structure API routes live in the `app` directory with `+api.ts` su

How do I install it?
Run `npx skills add sickn33/agentic-awesome-skills --skill expo-api-routes --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From sickn33/agentic-awesome-skills, a repository with 44,414 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
