Installation

``bash
npm install @unkey/nextjs
`

Quickstart

Protecting API routes is as simple as wrapping them with the withUnkey handler:

`ts
import { NextRequestWithUnkeyContext, withUnkey } from "@unkey/nextjs";

export const POST = withUnkey(
async (req) => {
// Process the request here
// You have access to the verification response using req.unkey
console.log(req.unkey);

return new Response("Your API key is valid!");
},
{
rootKey: process.env.UNKEY_ROOT_KEY!, // Required: Your Unkey root key
},
);
`

Note: You need to provide your Unkey root key for key verification. Get your root key from the Unkey dashboard.

Configuration Options

You can customize how withUnkey processes incoming requests by passing configuration options:

$3

- rootKey: Your Unkey root key (required for API authentication)

$3

- tags: Array of tags to filter keys during verification
- permissions: Required permissions for the key to be valid
- getKey: Custom function to extract the key from the request
- handleInvalidKey: Custom handler for invalid keys
- onError: Custom error handler

getKey

By default, withUnkey will look for a bearer token located in the authorization header. If you want to customize this, you can do so by passing a getter in the configuration object:

`ts
export const GET = withUnkey(
async (req) => {
// ...
},
{
rootKey: process.env.UNKEY_ROOT_KEY!,
getKey: (req) => new URL(req.url).searchParams.get("key"),
},
);
`

tags and permissions

You can require specific tags or permissions for key verification:

`ts
export const GET = withUnkey(
async (req) => {
// ...
},
{
rootKey: process.env.UNKEY_ROOT_KEY!,
tags: ["api", "production"],
permissions: "read:data",
},
);
`

onError

You can specify custom error handling. By default errors will be logged to the console, and withUnkey will return a NextResponse with status 500.

`ts
export const GET = withUnkey(
async (req) => {
// ...
},
{
rootKey: process.env.UNKEY_ROOT_KEY!,
onError: async (req, err) => {
await analytics.trackEvent(Error ${err.statusCode}: ${err.message});
return new NextResponse("Unkey error", { status: 500 });
},
},
);
`

handleInvalidKey

Specify what to do if Unkey reports that your key is invalid.

`ts
export const GET = withUnkey(
async (req) => {
// ...
},
{
rootKey: process.env.UNKEY_ROOT_KEY!,
handleInvalidKey: (req, res) => {
return new Response("Unauthorized", { status: 401 });
},
},
);
