Route Handler GeneratorGenerate Next.js App Router API route boilerplate with type safety.
API route boilerplate in the App Router is repetitive but must stay consistent, with the right methods, types, and error handling every time. This generator produces a complete, typed route.ts from a few options.
Building a new endpoint is the moment when boilerplate either saves time or creates inconsistency, and this generator targets exactly that moment. Use it to generate typed API route boilerplate for a new feature endpoint, create CRUD route handlers with proper error handling and validation, and set up authenticated API routes with middleware and CORS headers. Developers shipping features quickly rely on it for endpoints that are correct by construction.
The generated code follows current App Router practice. HTTP method toggles produce only the handlers you need, the output uses typed NextRequest and NextResponse objects from next/server, and optional middleware, auth checks, and error handling wrappers slot in without extra effort. One-click copy delivers the whole file to your clipboard, ready for the route.ts location.
Route handlers are the backend of your application, and the code you generate here often becomes the foundation for authentication, payments, and internal data flows. Pasting that boilerplate into an online generator shares the shape of your API and its security handling with a third party.
This generator runs entirely in your browser, so the code you produce never leaves your device. You can scaffold production endpoints and business logic privately, knowing the only copy of your API design is the one you create.
Toggle the HTTP methods you need — GET, POST, PUT, PATCH, DELETE. Only selected methods are included in the generated code.
Optionally enable authentication checks, error handling wrappers, and CORS headers to be included in the route handler.
Click Generate to create the complete route handler file with proper TypeScript types and imports.
Copy the generated code and paste it into your route.ts file in the App Router directory structure.
Practical examples to help you get the most out of Route Handler Generator:
import { NextRequest, NextResponse } from 'next/server'
export async function GET(request: NextRequest) {
const searchParams = request.nextUrl.searchParams
const query = searchParams.get('q')
return NextResponse.json({ query })
}import { NextRequest, NextResponse } from 'next/server'
export async function POST(request: NextRequest) {
try {
const body = await request.json()
return NextResponse.json(body, { status: 201 })
} catch (error) {
return NextResponse.json(
{ error: 'Invalid JSON' },
{ status: 400 }
)
}
}Use NextResponse.json() instead of new NextResponse(JSON.stringify(data)). NextResponse.json automatically sets the Content-Type header and stringifies the body.
Always export an OPTIONS handler for routes that need cross-origin access. Without it, browsers block CORS preflight requests.
GET, POST, PUT, PATCH, and DELETE handlers are all supported. Toggle only the methods you need for clean, minimal boilerplate.
Yes. The generated handlers use proper NextRequest and NextResponse types from next/server for full type safety.
Yes. The generator can optionally include authentication checks, error handling wrappers, and CORS headers in the generated route handler.
No. All boilerplate generation happens locally in your browser. Your code never leaves your device.
Toggle GET, POST, PUT, PATCH, DELETE handlers as needed.
Generate typed request handlers with proper NextRequest/NextResponse types.
Optionally include middleware, auth checks, and error handling.
Copy the complete route handler code to your clipboard.
Route Handler Generator is useful in a variety of scenarios across different workflows:
Generate typed API route boilerplate for a new feature endpoint
Create CRUD route handlers with proper error handling and validation
Set up authenticated API routes with middleware and CORS headers
Always use NextRequest and NextResponse from next/server for full type safety and built-in cookie and header helpers.
Always implement an OPTIONS handler for routes that need to support cross-origin requests from web browsers.
