`next-safe-route` is a utility library for Next.js that provides type-safety and schema validation for [Route Handlers](https://nextjs.org/docs/app/building-your-application/routing/route-handlers)/API Routes.

## Features

- **✅ Schema Validation:** Automatically validate request parameters, query strings, and body content with built-in error handling.

- **🧷 Type-Safe:** Work with full TypeScript type safety for parameters, query strings, and body content.

- **😌 Easy to Use:** Simple and intuitive API that makes defining route handlers a breeze.

- **🔗 Extensible:** Compatible with any validation library supported by [TypeSchema](https://typeschema.com).

- **🧪 Fully Tested:** Extensive test suite to ensure everything works reliably.

## Installation

```sh

npm install next-safe-route

```

The library natively works with [zod](https://zod.dev) for schema validation, but you can use any other validation library that is supported by [TypeSchema](https://typeschema.com), as long as you install its respective adapter.

## Usage

```ts

// app/api/hello/route.ts

import { createSafeRoute } from 'next-safe-route';

import { z } from 'zod';

const paramsSchema = z.object({

  id: z.string(),

});

const querySchema = z.object({

  search: z.string().optional(),

});

const bodySchema = z.object({

  field: z.string(),

});

export const GET = createSafeRoute()

  .params(paramsSchema)

  .query(querySchema)

  .body(bodySchema)

  .handler((request, context) => {

    const { id } = context.params;

    const { search } = context.query;

    const { field } = context.body;

    return Response.json({ id, search, field }), { status: 200 };

  });

```

To define a route handler in Next.js:

1. Import `createSafeRoute` and your validation library (e.g., `zod`).

2. Define validation schemas for params, query, and body as needed.

3. Use `createSafeRoute()` to create a route handler, chaining `params`, `query`, and `body` methods.

4. Implement your handler function, accessing validated and type-safe params, query, and body through `context`.

## Tests

Tests are written using [Vitest](https://vitest.dev). To run the tests, use the following command:

```sh

pnpm test

```
