Extended from common error, class TError allows create and cofigurate custom errors. Error's configuration allow using logging, user alert, debugging simple and fast.

Because i want unify work with errors. Make it simple and clean.

import { TErrorGroup } from '@rnskv/terror';

• Create errors white list;
• Create Errors Groups, using list from 1 step;
• Generate new errors in your code :).

const errorsList = {
  PAGE_NOT_FOUND: {
    message: 'Page not found :(', //Message for user
    name: 'REQUEST_ERROR', //Name for logging
    code: 404 //HTTP code
  },
  INTERNAL_SERVER_ERROR: {
    message: 'Internal Server Error', //Message for user
    name: 'RESPONSE_ERROR', //Name for logging
    code: 500 //HTTP code
  }
};

const params = {
  type: 'SERVER_ERROR'
};

const ServerErrors = new TErrorGroup(params, errorsList)

  try {
    throw ServerErrors.create('PAGE_NOT_FOUND');
    // Or
    throw ServerErrors.create('INTERNAL_SERVER_ERROR');
  } catch(error) {
    console.log('Catch error:', error)
  }

ServerErrors.setLogger(console.error);
