@logtape/hono

This package provides Hono middleware for HTTP request logging using LogTape as the backend, as an alternative to Hono's built-in logger middleware.

Installation

deno add jsr:@logtape/hono  # for Deno
npm  add     @logtape/hono  # for npm
pnpm add     @logtape/hono  # for pnpm
yarn add     @logtape/hono  # for Yarn
bun  add     @logtape/hono  # for Bun

Usage

import { Hono } from "hono";
import { configure, getConsoleSink } from "@logtape/logtape";
import { honoLogger } from "@logtape/hono";

await configure({
  sinks: { console: getConsoleSink() },
  loggers: [
    { category: ["hono"], sinks: ["console"], lowestLevel: "info" }
  ],
});

const app = new Hono();
app.use(honoLogger());

app.get("/", (c) => c.json({ hello: "world" }));

export default app;

Options

The honoLogger() function accepts an optional options object:

app.use(honoLogger({
  category: ["myapp", "http"],  // Custom category (default: ["hono"])
  level: "debug",                // Log level (default: "info")
  format: "dev",                 // Predefined format (default: "combined")
  skip: (c) => c.req.path === "/health",  // Skip logging for specific paths
  logRequest: true,              // Log at request start (default: false)
}));

Predefined formats

The middleware supports Morgan-compatible predefined formats:

• "combined": Apache Combined Log Format with all properties (default)
• "common": Apache Common Log Format (without referrer/userAgent)
• "dev": Concise output for development (e.g., GET /path 200 1.234 ms - 123)
• "short": Shorter format with remote address
• "tiny": Minimal output

Custom format function

You can also provide a custom format function:

app.use(honoLogger({
  format: (c, responseTime) => ({
    method: c.req.method,
    path: c.req.path,
    status: c.res.status,
    duration: responseTime,
  }),
}));

Structured logging output

When using the "combined" format (default), the middleware logs structured data that includes:

• method: HTTP request method
• url: Request URL
• path: Request path
• status: HTTP response status code
• responseTime: Response time in milliseconds
• contentLength: Response content-length header value
• userAgent: User-Agent header value
• referrer: Referrer header value
