Expo + Next
Expo + Next — full-stack framework with SSR, routing, data fetching, and API routes.
Stack Components
Why
Unified frontend+backend with SSR/SSG, file-based routing, and type-safe data flow. Full-stack frameworks reduce context switching and boilerplate by 40-60% compared to separate frontend/backend repos.
Next.js, Nuxt, and SvelteKit dominate with built-in SSR, routing, and data fetching.
When
Use for full-stack web apps needing SSR, SEO, and API in one project. Avoid for pure SPA (use Vite+React).
How
Example
Common Problems
- ⚠Expo + Next bundle size large — use code splitting and dynamic imports
- ⚠Hydration mismatches — ensure server/client render same output
- ⚠Configuration drift between environments — use infrastructure-as-code (Terraform/Pulumi) to keep dev/staging/prod identical
Best Practices
- ✓Use Expo + Next built-in data fetching for SSR/SSG
- ✓Leverage {ne} file-based routing for convention over config
- ✓Set up health checks and graceful shutdown — handle SIGTERM to drain in-flight requests before exit
FAQ
What is Expo + Next and what projects is it for?
Expo + Next — full-stack framework with SSR, routing, data fetching, and API routes. It pairs layered technologies for end-to-end type safety and out-of-the-box deploys, fitting everything from MVPs to production SaaS.
How do I spin up a working demo with Expo + Next in 10 minutes?
Two steps: (1) npx create-expo-next@latest myapp; (2) Write pages and API routes. Get the local dev server running, then wire one real data source to verify the end-to-end loop.
What is the most common pitfall with Expo + Next and how do I avoid it?
The most common pitfall is: Expo + Next bundle size large — use code splitting and dynamic imports. Avoid it by adding the matching checklist to your PR template and running type-check + lint + unit tests in CI — three gates before merge.
What are the best practices for Expo + Next?
Best practices for Expo + Next include: Use Expo + Next built-in data fetching for SSR/SSG; Leverage {ne} file-based routing for convention over config; Set up health checks and graceful shutdown — handle SIGTERM to drain in-flight requests before exit. The first one — "Use Expo + Next built-in data fetching for SSR/SSG" — should be set up at project init to avoid costly rework later.
When should I NOT choose Expo + Next?
Pick something else in three cases: (1) the team has zero experience with the core framework and the deadline is tight (learning-curve risk); (2) it's a pure content/marketing site (Astro is lighter); (3) you need very high throughput (>10k RPS) or strict-consistency microservices (Go/Rust). Expo + Next shines for mid-to-high complexity full-stack and API work — don't over-engineer simple static pages with it.
