Secure REST APIs with Node.js
Validation, auth boundaries, rate limits and safe error responses for production APIs.
Secure APIs start with validation and least privilege.
Authenticate early, authorize per resource, and never leak internals in error bodies. Rate-limit public endpoints. Hash secrets properly and keep them out of logs.
Treat uploads, webhooks and admin routes as higher-risk surfaces with stricter controls.
