bugsy

Collection of helpers to deal with errors.

Dealing with errors is a common problem in every kind of project. While a lot of libraries simply focus on their creation, this library is meant to deal whole way through their lifecycle.

Features

• Inheritance management
• Error severity support
• Matching transformations
• Flow definition

Installation

$ npm install bugsy

Usage

import * as bugsy from 'bugsy';

const RanAwayError = bugsy.create(
  'RanAwayError',
  'It ran away, again',
  { code: 'ran_away' }
);
const MissedThrowError = bugsy.create(
  'MissedThrowError',
  'Throw totally missed',
  { code: 'missed_throw' }
);

function capture() {
  if (Math.random() > 0.9) {
    throw new MissedThrowError();
  } else {
    throw new RanAwayError({ meta: 'Caterpie' }); 
  }
}

bugsy.transform(() => {
  capture();
}, [
  bugsy.code('missed_throw').drop(),
  bugsy.instanceOf(RanAwayError).transform(err => err.level = bugsy.LEVELS_SYSLOG.EMERGENCY)
]);
