Nextjs Trpc Mantine Boilerplate is a starter repository for building full-stack TypeScript web applications with the T3-Stack trio of Next.js and tRPC, plus the Mantine component library for UI.
What is Nextjs Trpc Mantine Boilerplate?
This boilerplate was bootstrapped according to create-t3-app, the official scaffold for the T3-Stack, and then preconfigured with Mantine as the styling solution. It provides a ready-to-run baseline: Next.js powers the React frontend and API routes, tRPC creates end-to-end typesafe procedures, and Mantine supplies a library of styled components such as buttons, modals, forms, and notifications. The entire codebase is written in TypeScript, so props, API payloads, and function signatures are statically checked during development. The repository lists Vercel deployment as a topic, indicating the project is configured to deploy to Vercel like most Next.js applications.
Key Features
- T3-Stack foundation — Uses the create-t3-app structure, so you get the conventional folder layout and utilities for Next.js development without manual configuration.
- tRPC integration — Connects the frontend and backend with fully typed queries and mutations, eliminating the need for hand-written REST endpoints and reducing runtime errors.
- Mantine component library — Includes Mantine, a React UI library with a theme system and a set of components like AppShell, Table, Modal, and Notification, ready to use instead of building custom CSS.
- TypeScript everywhere — The project is written in TypeScript, giving you static typing across server procedures, React components, and client-server communication.
- Vercel readiness — The repository's topics include vercel-deployment, signaling that the boilerplate is prepared for a Vercel deployment workflow, a common hosting choice for Next.js apps.
Who is it for?
- Full-stack TypeScript developers — Developers who want to start coding features immediately with a pre-wired integration of Next.js and tRPC, rather than spending time connecting them manually.
- Product teams shipping web apps — Teams building MVPs or internal tools who benefit from Mantine's ready-made UI components and type-safe data layer, letting them iterate faster.
- T3-Stack learners — Developers studying the T3-Stack who prefer a concrete example that swaps the default Tailwind styling for Mantine, showing how the architecture can adapt.
Use cases
- SaaS prototypes: Scaffold a new product with a fresh Next.js app, tRPC procedures, and Mantine forms so the first feature can be built within hours.
- Admin dashboards: Use Mantine's built-in Table, navigation, and modals alongside tRPC procedures to manage internal data with full type safety.
- Personal projects: Start a portfolio or side project with a fast, typed frontend and API, with Mantine handling the visual styling so you can focus on the logic.
Alternatives
- create-t3-app — The official scaffold this boilerplate is based on; the main difference is that create-t3-app lets you choose your UI library during setup, while this template ships specifically with Mantine preinstalled.
