Winston 3.0 colorize whole output on console

simply use addColors() method

const { createLogger, format, transports, addColors } = require('winston');
const { combine, colorize, label, timestamp, json, prettyPrint, printf } = format;
require('winston-mongodb');

let myCustomFormat = format.combine(
  colorize({ all: true }),
  label({ label: '[LOGGER]' }),
  timestamp({ format: 'YY-MM-DD HH:MM:SS' }),
  printf(
    (info) =>
      ` ${info.label} ${info.timestamp}  ${info.level} : ${info.message}`
  )
);

addColors({
  info: 'bold blue', // fontStyle color
  warn: 'italic yellow',
  error: 'bold red',
  debug: 'green',
});

const logger = createLogger({
  level: 'info',
  transports: [new transports.Console({ format: combine(myCustomFormat) })],
});

This worked for me for customizing colors and font style.

Possible options from the doc are below.

Font styles: bold, dim, italic, underline, inverse, hidden, strikethrough.

Font foreground colors: black, red, green, yellow, blue, magenta, cyan, white, gray, grey.

Background colors: blackBG, redBG, greenBG, yellowBG, blueBG magentaBG, cyanBG, whiteBG

Try with the code below. It will combine both formatting. It works for me.

let alignColorsAndTime = winston.format.combine(
    winston.format.colorize({
        all:true
    }),
    winston.format.label({
        label:'[LOGGER]'
    }),
    winston.format.timestamp({
        format:"YY-MM-DD HH:mm:ss"
    }),
    winston.format.printf(
        info => ` ${info.label}  ${info.timestamp}  ${info.level} : ${info.message}`
    )
);
    
export const logger = winston.createLogger({
    level: "debug",
    transports: [
        new (winston.transports.Console)({
            format: winston.format.combine(winston.format.colorize(), alignColorsAndTime)
        })
    ],
});

Note the padding has to handle the colour. Ex:

const padding= info.level.length <= 7?7:17;  //padding differently if it has colour.
${info.level.padEnd(padding,' ')}

Tested with:

"winston": "^3.1.0"
