Bringing Node.js HTTP servers to Cloudflare Workers
We’re making it easier to run your Node.js applications on Cloudflare Workers by adding support for the node:http client and server APIs. This significant addition brings familiar Node.js HTTP interfaces to the edge, enabling you to deploy existing Express.js, Koa, and other Node.js applications globally with zero cold starts, automatic scaling, and significantly lower latency for your users — all without rewriting your codebase. Whether you're looking to migrate legacy applications to a modern serverless platform or build new ones using the APIs you already know, you can now leverage Workers' global network while maintaining your existing development patterns and frameworks.
Cloudflare Workers operate in a unique serverless environment where direct tcp connection isn't available. Instead, all networking operations are fully managed by specialized services outside the Workers runtime itself — systems like our Open Egress Router (OER) and Pingora that handle connection pooling, keeping connections warm, managing egress IPs, and all the complex networking details. This means as a developer, you don't need to worry about TLS negotiation, connection management, or network optimization — it's all handled for you automatically.
This fully-managed approach is actually why Continue reading
New URLPattern API brings improved pattern matching to Node.js and Cloudflare Workers
Today, we are excited to announce that we have contributed an implementation of the URLPattern API to Node.js, and it is available starting with the v23.8.0 update. We've done this by adding our URLPattern implementation to Ada URL, the high-performance URL parser that now powers URL handling in both Node.js and Cloudflare Workers. This marks an important step toward bringing this API to the broader JavaScript ecosystem.
Cloudflare Workers has, from the beginning, embraced a standards-based JavaScript programming model, and Cloudflare was one of the founding companies for what has evolved into ECMA's 55th Technical Committee, focusing on interoperability between Web-interoperable runtimes like Workers, Node.js, Deno, and others. This contribution highlights and marks our commitment to this ongoing philosophy. Ensuring that all the JavaScript runtimes work consistently and offer at least a minimally consistent set of features is critical to ensuring the ongoing health of the ecosystem as a whole.
URLPattern API contribution is just one example of Cloudflare’s ongoing commitment to the open-source ecosystem. We actively contribute to numerous open-source projects including Node.js, V8, and Ada URL, while also maintaining our own open-source initiatives like workerd and wrangler. By upstreaming improvements Continue reading
