Small, composable HTTP helper functions — retry with backoff, timeouts, normalized errors, safe JSON parsing, rate-limit-aware retry, and download progress. Not a client, works alongside fetch/axios/anything.
Maintained drop-in replacement for the abandoned isomorphic-unzip — same API (getBuffer, string/RegExp/function matching), powered internally by fflate instead of a yauzl+zip.js split that never actually reached parity between Node and browser.
