The author shares their experience hitting usage limits and unexpected charges, then explains their solution: caching GET APIs and moving heavy logic to a separate Node.js backend for better cost efficiency and scalability.
InfoQ·35wCloudflare Adds Node.js HTTP Servers to Cloudflare Workers
Cloudflare Workers now supports Node.js HTTP client and server APIs, enabling developers to migrate existing Express.js and Koa.js applications to the serverless platform without code rewrites. The implementation uses a bridge system that connects Node.js-style servers to Workers' request handling model, offering zero cold starts and automatic scaling while maintaining compatibility with popular Node.js frameworks.
Hacker News·35wPython on the Edge: Fast, sandboxed, and powered by WebAssembly · Blog · Wasmer
Wasmer announces full Python support in Wasmer Edge (Beta), enabling Python applications to run on WebAssembly with near-native performance. The platform supports popular frameworks like FastAPI, Django, and Streamlit, along with native modules like numpy and pandas. Key improvements include dynamic linking support, threading capabilities, and a custom Python Package Index. Performance benchmarks show 6x faster execution than previous versions, approaching native Python speeds while maintaining full sandboxing. The solution addresses limitations found in Cloudflare Workers and AWS Lambda by supporting WebSockets, multiprocessing, and raw sockets without requiring code modifications.
