Cloudflare Worker

Cloud Auth is fully compatible with Cloudflare Workers and can verify requests like this:

import { createVerifier } from '@featherscloud/auth';

const appId = '<your-app-id>';
const verifier = createVerifier({ appId });

const headers = {
  'Content-Type': 'application/json',
  'Access-Control-Allow-Headers': '*',
  'Access-Control-Allow-Methods': 'GET',
  'Access-Control-Allow-Origin': '*'
};
export default {
	async fetch(request, env, ctx): Promise<Response> {
		// Handle CORS preflight request
		if (request.method === 'OPTIONS') {
			return new Response(null, {
				status: 200,
				headers
			});
		}
	
		try {
			const header = request.headers.get('Authorization');

			if (!header) {
				throw new Error('Invalid Authorization header');
			}

			// Verify the Authorization header and get the user information
			const { user } = await verifier.verifyHeader(header);

			if (!user) {
				throw new Error('Cloud auth user not found')
			}

			const body = {
				message: `Hello ${user.email} from Cloudflare Worker!`
			};
	
			return Response.json(body, {
				status: 200,
				headers
			});
		} catch (error) {
			return Response.json({ error: (error as any).message }, {
				status: 400,
				headers
			});
		}
	},
} satisfies ExportedHandler<Env>;
