Arcjet helps developers protect their apps in just a few lines of code. Implement rate limiting, bot protection, email verification & defend against common attacks.
This is the Arcjet TypeScript and JavaScript SDK core.
Visit docs.arcjet.com to get started.
Generally, you'll want to use the Arcjet SDK for your specific framework, such
as @arcjet/next
for Next.js. However, this package
can be used to interact with Arcjet if your framework does not have an
integration.
npm install -S arcjet
import http from "http";
import arcjet, { createRemoteClient, defaultBaseUrl } from "arcjet";
import { createConnectTransport } from "@connectrpc/connect-node";
const aj = arcjet({
// Get your site key from https://app.arcjet.com
// and set it as an environment variable rather than hard coding.
// See: https://www.npmjs.com/package/dotenv
key: process.env.ARCJET_KEY,
rules: [],
client: createRemoteClient({
transport: createConnectTransport({
baseUrl: defaultBaseUrl(),
httpVersion: "2",
}),
}),
});
const server = http.createServer(async function (
req: http.IncomingMessage,
res: http.ServerResponse,
) {
// Construct an object with Arcjet request details
const path = new URL(req.url || "", `http://${req.headers.host}`);
const details = {
ip: req.socket.remoteAddress,
method: req.method,
host: req.headers.host,
path: path.pathname,
};
const decision = await aj.protect(details);
console.log(decision);
if (decision.isDenied()) {
res.writeHead(403, { "Content-Type": "application/json" });
res.end(JSON.stringify({ error: "Forbidden" }));
} else {
res.writeHead(200, { "Content-Type": "application/json" });
res.end(JSON.stringify({ data: "Hello World!" }));
}
});
server.listen(8000);
