Tired of Boilerplate in Next.js 15 Route Handlers? Meet next-routed

Description and use

next-routed eliminates repetitive boilerplate in Next.js 15 route handlers, enabling concise, type-safe pipelines.

Problem

Writing Next.js 15 route handlers requires repetitive boilerplate for auth, param extraction, body parsing, validation, and error handling.

Outcome

next-routed reduces boilerplate from ~35 lines to a concise pipeline, infers types automatically, and centralizes error handling, improving developer productivity.

Workflow

• Install next-routed via npm or pnpm
• Create a reusable auth middleware with route.use and RouteResponse
• Define the endpoint pipeline using route.use, passing schema and business logic
• next-routed handles param extraction, body parsing, validation, auth, and error responses automatically

Evidence

Every time you write an endpoint, you end up repeating the exact same ceremonies: 1. Wrapping everything in try/catch. 2. Extracting and parsing JSON bodies with await request.json(). 3. Running schema validation (like Zod) and manually structuring a 400 response. 4. Manually unwrapping asynchronous dynamic parameters in Next.js 15 (await context.params). 5. Writing repetitive authentication checks and duplicating TypeScript types.

Source

With next-routed, you define your route as a composable pipeline. Types are inferred automatically from your schemas and middlewares — no manual type definitions required.
