@tinyhttp/logger

Minimal and flexible HTTP logger

Install

pnpm i @tinyhttp/logger

API

import { logger } from '@tinyhttp/logger'

logger(options)

Returns the middleware for logging HTTP requests.

Options

• methods: a list of HTTP methods to log. Defaults to http's METHODS.
• timestamp.format: timestamp format. It is consumed by the dayjs library. If a string is specified, it is used as a format; otherwise just enabled.
• output.callback: a function that receives the log generated by the logger.
• output.color: a property that determines whether the logger will generate a message with color. Useful for logging into the console; disable if logging into a file or other colorless environments.
• emoji: enable emojis for HTTP status codes. See http-status-emojis for a full list.
• ip: log IP address.

Example

import { App } from '@tinyhttp/app'
import { logger } from '@tinyhttp/logger'

new App()
  .use(
    logger({
      methods: ['GET', 'POST'],
      timestamp: { format: 'HH:mm:ss' },
      output: { callback: console.log, color: false }
    })
  )
  .get('/', (req, res) => res.send('Hello world'))
  .post('/', (req, res) => res.send('Sent POST'))
  .listen(3000)

To Log a level, use the enum LogLevel

import { App } from '@tinyhttp/app'
import { logger, LogLevel } from '@tinyhttp/logger'

new App()
  .use(
    logger({
      methods: ['GET', 'POST'],
      timestamp: { format: 'HH:mm:ss' },
      output: { callback: console.log, color: false, level: LogLevel.warn }
    })
  )
  .get('/', (req, res) => res.send('Hello world'))
  .listen(3000)

This also includes a simple file logger. To stream to a file, simply supply the filename in the options. Supported file names innclude ./file.log or ./log/tiny.log

import { App } from '@tinyhttp/app'
import { logger } from '@tinyhttp/logger'

new App()
  .use(
    logger({
      methods: ['GET', 'POST'],
      timestamp: { format: 'HH:mm:ss' },
      output: { callback: console.log, color: false, filename: './log/tiny.log' }
    })
  )
  .get('/', (req, res) => res.send('Hello world'))
  .listen(3000)
