hono logger with log levels

Is there anyway we can use hono logging Middleware the way we use pino js e.g.?

You can use your choice of logger with the hono logger middleware - https://hono.dev/middleware/builtin/logger#printfunc

Or are you talking about the implementation then can you share some sudo code?

inorder to use pino with different log levels, I have combined them like this:

import { serve } from "@hono/node-server";
import { Hono } from "hono";
import { logger as loggerMiddleware } from "hono/logger";
import pino from "pino";

const app = new Hono();

const logger = pino({
  transport: {
    target: "pino-pretty",
    options: {
      colorize: true,
    },
  },
  level: "trace",
});

export const customLogger = (message: string, ...rest: string[]) => {
  logger.info(message, ...rest);
};

app.use(loggerMiddleware(customLogger));

app.get("/", (c) => {
  logger.info("hello");
  return c.text("Hello Hono!");
});

const port = 3000;
console.log(`Server is running on port ${port}`);

serve({
  fetch: app.fetch,
  port,
});

import { serve } from "@hono/node-server";
import { Hono } from "hono";
import { logger as loggerMiddleware } from "hono/logger";
import pino from "pino";

const app = new Hono();

const logger = pino({
  transport: {
    target: "pino-pretty",
    options: {
      colorize: true,
    },
  },
  level: "trace",
});

export const customLogger = (message: string, ...rest: string[]) => {
  logger.info(message, ...rest);
};

app.use(loggerMiddleware(customLogger));

app.get("/", (c) => {
  logger.info("hello");
  return c.text("Hello Hono!");
});

const port = 3000;
console.log(`Server is running on port ${port}`);

serve({
  fetch: app.fetch,
  port,
});
