Installation

$ npm install koa-logger

Example

const logger = require('koa-logger')
const Koa = require('koa')
 
const app = new Koa()
app.use(logger())

Notes

Recommended that you .use() this middleware near the top to "wrap" all subsequent middleware.

Use Custom Transporter

const logger = require('koa-logger')
const Koa = require('koa')
 
const app = new Koa()
app.use(logger((str, args) => {
  // redirect koa logger to other output pipe
  // default is process.stdout(by console.log function)
}))

or

app.use(logger({
  transporter: (str, args) => {
    // ...
  }
}))

Param str is output string with ANSI Color, and you can get pure text with other modules like strip-ansi
Param args is a array by [format, method, url, status, time, length]
