Next.js with Hono (as API package) and OpenAPI

A full-stack boilerplate combining Next.js App Router (frontend) with Hono (backend API), fully documented using OpenAPI and integrated with Scalar for interactive API documentation. The Hono application is encapsulated in a standalone api package, and seamlessly mounted into Next.js via the catch-all API route.

Features

Next.js App Router for modern frontend development.
Hono as the backend API framework for fast and lightweight routing.
OpenAPI integration for fully documented REST API.
Scalar for interactive and shareable API documentation.
Full CRUD example implemented entirely within the Hono API.
Packages/api encapsulating the entire Hono API as a standalone package.
Seamless integration with Next.js via app/api/[[...route]]/route.ts.
TypeScript support for type-safe development.
Monorepo structure for clean modular organization.

Use Case

Ideal for developers building API-first applications using Hono and Next.js with a clean separation between frontend and backend logic. The combination of OpenAPI and Scalar ensures complete, interactive, and self-documented APIs, making this boilerplate perfect for SaaS platforms, developer-facing APIs, and full-stack web applications. 🚀
