Logging

Unified Errors Handler can centralize logging of error for your NodeJS app.

1. ConsoleLogger

const options = {
  loggerOptions: {
    console: {
      format: ':time :message', // optional - default message only
      colored: true,    // optional - default no color
    },
  },
}

expressExceptionHandler(options)
// or 
const mappedError = exceptionMapper(err, options);

2. CustomLogger

implement ILogger interface

import { ILogger } from 'unified-errors-handler';

class CustomLogger implements ILogger {
  log(error: any): void {
    console.log(error.message);
  }
}

// in options pass this object
const options = {
  loggerOptions: {
    custom: new CustomLogger(),
  },
}

expressExceptionHandler(options)
// or 
const mappedError = exceptionMapper(err, options);
