To reduce the upload size of a Worker, you should consider removing unnecessary dependencies and/or using Workers KV, a D1 database or R2 to store configuration files, static assets and binary data instead of attempting to bundle them Today, we’re excited to share a collection of ready-made templates to help you build your next application on Cloudflare Workers.
