Way to use this lib while piping the output to another lib. about friendly-errors-webpack-plugin

I solved my issue by not having a raw json output that pipes to bunyan. And by using a custom stream with prettycli to match the output of bagpack and bunyan.

// logger
import { createLogger, nameFromLevel } from 'bunyan';
import * as prettyCli from 'prettycli';
import { utc as moment } from 'moment';

class PrettyStream {
  write(data) {
    let { module, time, level, msg } = JSON.parse(data);
    level = nameFromLevel[level] || 'info';
    time = moment(time).format('hh:mm A');
    const allowed = ['info', 'warning', 'loading', 'error'];
    const prettyMode = allowed.includes(level) ? level : 'loading';
    prettyCli[prettyMode](level.toUpperCase(), `[${time}] [${module}] ${msg}`);
  }
}

export default createLogger({
  name: 'myApp',
  streams: [
    {
      level: 'debug',
      stream: new PrettyStream()
    }
  ]
});

// app.js
import logger from './logger'
const apiLogger = logger.child({ module: 'api' })
apiLogger.info('hoorah')
