Yet anthor logger tool

Works on Nodejs and Browsers

Terminal:

Browser:

Install

npm i -D @rabbitcc/log

Usage

import log from '@rabbitcc/log'

log.info('name', 'action', 'contents')

Setup logger level

// via cross-env scripts

cross-env LOGGER_LEVEL=DEBUG

Or if you want works on browser, can pass the evn via webpack.EnvironmentPlugin

plugins: [
  //...other plugins

  new EnvironmentPlugin([ 'LOGGER_LEVEL' ]),

  // or pass default level if not set

  new EnvironmentPlugin({ LOGGER_LEVEL: process.env.LOGGER_LEVEL }),
]

You can pass log level by number and string type, below syntax are vaild.

cross-env LOGGER_LEVEL=warn
cross-env LOGGER_LEVEL=WARN
cross-env LOGGER_LEVEL=40

If process.env.DEBUG flag was found, the logger level is set to DEBUG.

There is some build-in logger levels:

| NAME | WEIGHT | DEFAULT? | |-------|--------|----------| | trace | 100 | no | | debug | 80 | no | | info | 60 | yes | | warn | 40 | no | | error | 20 | no | | fatal | 0 | no |

By the way, the FATAL level will highlight by background color.

Feature, log with origin file position

Enable this feature need setup as babel plugins:

{
  "plugins": ["@rabbitcc/log/inject-position"]
}

// setup with options

{
  "plugins": [["@rabbitcc/log/inject-position", {
    // ...options see below
  }]]
}

The inject position plugin options:

type InjectPositionPluginOptions = {
  test?: RegExp = /^@rabbitcc\/log/
}

In browser, you need to add folder to chrome devtools workspace.

This feature also works on terminal. Your terminal should support hyperlinks.

Feature, log sync on terminal and browser via webpack-hot-client socket server

If you want log both on terminal and browser, like this:

You can use createSocket with webpack-serve via WebSocket.

Setup browsers:

import log, { createSocket } from '@rabbitcc/log/socket'

if('production' !== process.env.NODE_ENV) {
  createSocket({ /* ...options see below */ })
}

log.info('name', 'action', 'contents')

And apply logger to webpack.config.js:

import { createSocket } from '@rabbitcc/log/socket'

serve: {
  on: {
    listening() {
      createSocket({ /* ...options see below */ })
    }
  }
}

The createSocket options:

type CreateSocketOptions = {
  /**
   * socket url, default to webpack-hot-client ws socket string
   */
  socket?: string = 'ws://localhost:8081'
}
