Cipher Logger

See every request. Capture every error. Understand your application.

---

Cipher Logger is a lightweight, production-ready HTTP request logging library for Node.js. It captures every request with adapters for Express, Next.js, Fastify, Hono, NestJS, and Nuxt, with full control over which fields get logged.

Highlights

• TypeScript-first, fully typed API
• Configurable fields — required fields always logged, optional fields opt-in
• Framework adapters via subpath imports (cipher-logger/express, cipher-logger/next, …)
• Zero heavy dependencies — only your framework as an optional peer dependency
• Node.js 18+

Installation

npm install cipher-logger
# or
pnpm add cipher-logger
# or
yarn add cipher-logger

Quick Start

import { createCipherLogger } from "cipher-logger";
import { createExpressMiddleware } from "cipher-logger/express";

const cipher = createCipherLogger({
  fields: { ip: true, userAgent: true, query: true },
  level: "info",
});

app.use(createExpressMiddleware(cipher));
// or: app.use(cipher.express());
