Log

Lightweight simple ECMAScript logging for Browser and Node.js


Features

- Loggin things (message, data) at a given level with API trace(), debug(), log(), info(), warn(), error()
- Filter logging by runLevel (all the below or 'silent'), so you can run site with default runLevel error, and run setRunLevel('trace') for debugging

Installing

``bash
npm install @waiting/log
`

Usage

$3

`ts
import { error, trace, setRunLevel } from '@waiting/log'

error('log message')

setRunLevel('trace')
const data = {
foo: new Date()
}
trace(data)
setRunLevel('error') // turn trace off
`

$3

`ts
import * as log from '@waiting/log'

log.error('log message')

log.setRunLevel('trace')
const data = {
foo: new Date()
}
log.log(data) // equal to console.log()
log.setRunLevel('error') // turn debug off
`

$3

- Needs polylfill node-localstorage for persistent logging

import { LocalStorage } from 'node-localstorage'

// @ts-ignore
global.localStorage = new LocalStorage()
``
