About
I wanted to be able to have chattier daemons running in development, and more succinct logging in production but wanted to keep the simplicity of using console.log()
etc.
Normally I pass in a granular verboseness level via arguments to control the verbosity level for the running process.
Installation
npm install --save verbosity
Examples
Simply override the built in console object:
import {createConsole} from 'verbosity'
const console = createConsole({
outStream: process.stdout,
errorStream: process.stderr,
verbosity: 5
})
console.log('Works like normal...')
console.debug('...but now controllable.')
console.verbosity(3) // Use numbered levels 5 (debug) to 1 (error)
console.debug('...this isn’t printed now.')
console.canWrite(5) && console.dir({print: 'this won’t.'})
console.verbosity('debug') // Use named levels [debug, info, log, warning, error]
console.canWrite(5) && console.dir({print: 'this will now.'})
This will direct all console output to stderr, but silence 'info' and 'debug' messages.
import {createConsole} from 'verbosity'
const console = createConsole({
outStream: process.stderr,
verbosity: 3
})
console.log('Picked brown jacket...') // Printed
console.debug('Purple tie chosen...') // Not printed
console.warn("That tie doesn't go with that jacket.") // Printed
Or go mad with making up any number of custom console writers.
import {createConsole} from 'verbosity'
const myUberConsole = createConsole({
outStream: myFancyWriteableStream,
verbosity: 5
})
myUberConsole.panic('Core Flux Capacitor Meltdown!')
