@arcjet/next
Arcjet helps developers protect their apps in just a few lines of code. Bot detection. Rate limiting. Email validation. Attack protection. Data redaction. A developer-first approach to security.
This is the Arcjet SDK for the Next.js framework. Find our other SDKs on GitHub.
Try an Arcjet protected app live at https://example.arcjet.com (source code).
Arcjet security features for protecting Next.js apps:
Content-Security-Policy (CSP).This example will protect a Next.js API route with a rate limit, bot detection, and Shield WAF.
You can also find this quick start guide in the docs.
This is our adapter to integrate Arcjet into Next.js. Arcjet helps you secure your Next web application. This package exists so that we can provide the best possible experience to Next users.
You can use this if you are using Next.js. See our Get started guide for other supported frameworks.
This package is ESM only. Install with npm in Node.js:
npm install @arcjet/next
import arcjet, { shield } from "@arcjet/next";
import { NextResponse } from "next/server";
// Get your Arcjet key at <https://app.arcjet.com>.
// Set it as an environment variable instead of hard coding it.
const arcjetKey = process.env.ARCJET_KEY;
if (!arcjetKey) {
throw new Error("Cannot find `ARCJET_KEY` environment variable");
}
const aj = arcjet({
key: arcjetKey,
rules: [
// Shield protects your app from common attacks.
// Use `DRY_RUN` instead of `LIVE` to only log.
shield({ mode: "LIVE" }),
],
});
export async function GET(request: Request) {
const decision = await aj.protect(request);
if (decision.isDenied()) {
return NextResponse.json({ message: "Forbidden" }, { status: 429 });
}
return NextResponse.json({ message: "Hello world" });
}
