Zod Route

The zod-route.ts module provides type-safe API route handlers using next-zod-route with built-in validation, authentication, and authorization.

Available Route Handlers

route - Base Handler

Base route handler with automatic error handling and validation. No authentication required.

import { route } from "@/lib/zod-route";

export const POST = route
  .params(z.object({ id: z.string() }))
  .body(z.object({ name: z.string() }))
  .query(z.object({ page: z.number().optional() }))
  .handler(async (req, { params, body, query }) => {
    return { success: true };
  });

authRoute - Authenticated Handler

Requires a valid user session. Provides ctx.user in the handler.

import { authRoute } from "@/lib/zod-route";

export const GET = authRoute.handler(async (req, { ctx }) => {
  const { user } = ctx;
  return { userId: user.id };
});

orgRoute - Organization Handler

Requires organization membership with optional role/permission checks. Provides ctx.organization in the handler.

import { orgRoute } from "@/lib/zod-route";

// Basic organization route
export const GET = orgRoute.handler(async (req, { ctx }) => {
  const { organization } = ctx;
  return { orgId: organization.id };
});

// With permissions
export const POST = orgRoute
  .metadata({ permissions: { users: ["create"] } })
  .body(z.object

Request Validation

URL Parameters

Use .params() for dynamic route segments:

// Route: /api/users/[id]/route.ts
export const GET = route
  .params(z.object({ id: z.string().uuid() }))
  .handler(async (req, { params }) => {
    return await getUser(params.id);
  });

Request Body

Use .body() for JSON body validation:

export const POST = route
  .body(
    z.object({
      name: z.string().min(1),
      email: z.string().email(),
      age: z.number().positive().optional(),
    }),
  )
  .handler(async (req, { body }) => {
    return await createUser(body);

Query Parameters

Use .query() for URL search parameters:

export const GET = route
  .query(
    z.object({
      page: z.coerce.number().default(1),
      limit: z.coerce.number().default(10),
      search: z.string().optional(),
    }),
  )
  .handler(async (req, { query }) => {
    return await listItems(query);

Error Handling

The route handlers automatically handle errors:

Error Type	Status	Behavior
ZodRouteError	Custom	Returns error message with specified status
ApplicationError	400	Returns error message
Unknown Error (dev)	500	Returns full error message
Unknown Error (prod)	500	Returns "Internal server error"

Throwing Errors

import { ZodRouteError } from "@/lib/errors/zod-route-error";

export const GET = authRoute
  .params(z.object({ id: z.string() }))
  .handler(async (req, { params, ctx }) => {
    const item = await getItem(params.id);

    if (!item) {
      throw new ZodRouteError("Item not found", 404

Metadata for Authorization

Use .metadata() with orgRoute to define required roles or permissions:

// Require specific roles
export const DELETE = orgRoute
  .metadata({ roles: ["admin", "owner"] })
  .handler(async (req, { ctx }) => {
    // Only admin or owner can access
  });

// Require specific permissions
export const POST = orgRoute
  .metadata({ permissions: { billing: ["update"] } })
  .handler(async (req, { ctx
