cloudflare-firebase-jwt v1.0.0
cloudflare-firebase-jwt-verifier
A lightweight JWT verifier for Firebase Auth running on Cloudflare Workers. This lib fetches, caches keys from Firebase, and verifies the JWT token.
Why
Cloudflare Workers runtime doesn't support Node.js core modules, which means we cannot use common libs like jsonwebtoken
.
Install
npm i --save cloudflare-firebase-jwt-verifier
yarn add cloudflare-firebase-jwt-verifier
Usage
import { getVerifier, JwtInvalidError } from 'cloudflare-firebase-jwt-verifier';
const { verify } = getVerifier(firebaseProjectId);
export async function verifyAuth(request: Request) {
const header = request.headers.get('Authorization');
if (!header) {
throw new JwtInvalidError();
}
return await verify(header);
}
addEventListener('fetch', (event) => {
event.passThroughOnException();
event.respondWith(async (event) => {
const auth = await verifyAuth(request);
const userId = auth?.payload.sub;
return new Response({});
});
});
