Neutrx Documentation

Neutrx is a security-first HTTP client for Node.js 18+ backend services. It keeps Axios-like request ergonomics, then adds backend controls for SSRF protection, redirect safety, retries, circuit breaking, bulkhead isolation, cache metrics, typed redacted errors, and OpenTelemetry-friendly hooks.

Use these docs to get a production service client running quickly, migrate Axios code safely, and tune security and resilience behavior without adding runtime dependencies to Neutrx core.

Start Here

• Getting started: install Neutrx and make your first client.
• Axios migration guide: move common Axios patterns to Neutrx in one pass.
• Full-stack and frontend migration: compare browser/server adapter behavior, fetch support, defaults, headers, interceptors, progress events, and Axios workflow mappings.
• Node infrastructure usage: configure Docker sockets, local proxies, redirects, decompression, encodings, timeout diagnostics, bandwidth caps, and operational utility methods.
• Security features: understand profiles, SSRF controls, redirect policy, egress policy, and redacted errors.
• API reference: find request config, response shapes, adapters, plugins, errors, and utility methods.
• Support and sustainability: find public support, private security reporting, and sponsorship paths.

Common Paths
