T3 Stack

T3 Stack — full-stack framework with SSR, routing, data fetching, and API routes.

Stack Components

tRPCType-safe

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

1. npx create-t3@latest myapp 2. Write pages and API routes 3. Add data fetching 4. npm run build && start

Example

// T3 Stack page export default function Page() { return <h1>Hello from T3 Stack</h1>; }

Common Problems

  • ⚠T3 Stack 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 T3 Stack 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 T3 Stack and what projects is it for?

T3 Stack — 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 T3 Stack in 10 minutes?

Two steps: (1) npx create-t3@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 T3 Stack and how do I avoid it?

The most common pitfall is: T3 Stack 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 T3 Stack?

Best practices for T3 Stack include: Use T3 Stack 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 T3 Stack built-in data fetching for SSR/SSG" — should be set up at project init to avoid costly rework later.

When should I NOT choose T3 Stack?

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). T3 Stack shines for mid-to-high complexity full-stack and API work — don't over-engineer simple static pages with it.
