tRPC v11 Integrates with Next.js App Router
A developer tutorial shows how tRPC v11 (now stable) integrates natively with the Next.js App Router to provide end-to-end TypeScript safety with less boilerplate. The post includes installation commands, router/provider/handler code examples, and patterns for calling tRPC procedures from Server Components (using createCaller) and Client Components. It highlights features such as full TypeScript inference, typed middleware, WebSocket subscriptions, optimistic updates via trpc.useUtils(), and mapped error handling. The author recommends avoiding tRPC WebSocket subscriptions unless real-time push is required and cautions about mixing tRPC with Server Actions. The article also links to paid starter kits and related products on whoffagents.com.
tRPC v11 improves full-stack TypeScript developer workflows (native App Router support and server-side direct calls), which can speed product development for web and martech teams but is not an industry-shifting platform change.

Key Takeaways & Evidence Grounding
- tRPC v11 is stable and provides first-class support for the Next.js App Router.
- tRPC enables end-to-end TypeScript inference for inputs and outputs and supports procedures from Server Components, Client Components, and Server Actions.
- The createCaller pattern allows invoking tRPC procedures directly in Server Components without an HTTP round-trip.
- The post includes example installation commands (npm install @trpc/server @trpc/client @trpc/react-query @trpc/next zod and @tanstack/react-query) and code samples for router, handler, and client provider setup.

Introduction to Next.js
This developer tutorial explains Next.js, a React framework for building faster, SEO-friendly and full‑stack web applications. It outlines Next.js core features — file-based routing, Server-Side Rendering (SSR), Static Site Generation (SSG), and built-in API routes — and contrasts Next.js with plain React SPAs. The post describes the two routing approaches (Pages Router vs App Router), recommends the modern App Router for new projects, and explains Server Components (default) versus Client Components (which require "use client"). It covers project structure (including the app/ folder), styling options (global CSS, CSS Modules, Tailwind CSS), basic npm commands (dev/build/start), and real‑world benefits such as SEO, performance optimizations, and easy deployment via Vercel.
Build a Type-Safe Next.js 15 + Strapi v5 Blog
A technical tutorial demonstrates how to build a type-safe Next.js 15 blog backed by Strapi v5 using the open-source package strapi-typed-client. The package provides a Strapi plugin and a Next.js client that generate TypeScript types from the Strapi schema, expose a schema endpoint and an SSE "schema-watch" for live updates, and integrate with Next.js via withStrapiTypes in next.config.ts. Features include automatic type regeneration during next dev and next build, typed populate/filters/pagination that reflect requested fields, nested populate typing, Next.js caching/revalidation support, and typed error classes. Documentation and source code are hosted on boxlab-ltd.github.io and GitHub (BoxLab-Ltd/strapi-typed-client).
Colocate Your API Layer for Scalable Next.js Apps
This technical article describes a scalable pattern for Next.js App Router projects: colocating API functions inside each feature directory instead of a centralized services/ folder. The pattern was developed while building a production retail POS with Next.js 15, running separate Admin and Merchant dashboards across 30+ feature modules. Each feature exposes plain TypeScript async functions in api/index.ts and imports a single globally shared, typed Axios instance that centralizes baseURL, request token injection, and response-error handling. Role-aware TokenService resolves admin/merchant/user tokens from path-derived, namespaced cookies. Colocated modules integrate with React Query (useQuery/useQueries) as queryFn providers, keep shared utilities and types global, and reduce accidental coupling, namespace collisions, and dead code. The article details trade-offs (intentional duplication, discovery via grep) and offers concrete folder structures and code examples demonstrating date formatting, query building, and queryKey design for cache correctness.
