This is a simple implementation of the xBrowserSync API using Cloudflare workder. It uses Cloudflare KV as storage.

• Create a Cloudflare worker project
• Create a KV namespace, and add KV binding in the worker project, name it as XBSKV
• Paste the content of index.js into worker, modify the settings and then save and deploy
• Profit

Point your xBrowserSync plugin/app to your worker URL
