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

• Isomorphic module
• Error severity support
• Flowtype support

Installation

$ npm install bugsy

Usage

import * as bugsy from 'bugsy';

const CODE_RAN_AWAY = 'ran_away';
const CODE_THROW_MISSED = 'throw_missed';

const RanAwayError = bugsy.newError(CODE_RAN_AWAY, 'It ran away, again');
const ThrowMissedError = bugsy.newError(CODE_THROW_MISSED, 'Throw totally missed');

function capture() {
  if (Math.random() > 0.9) {
    throw new ThrowMissedError({ severity: bugsy.SYSLOG_WARNING });
  } else {
    throw new RanAwayError();
  }
}

function handler(fn) {
  try {
    fn();
  } catch (err) {
    console.log(bugsy.toString(err));
  }
}

handler(() => {
  try {
    capture();
  } catch (err) {
    switch (true) {
      case err.code === CODE_THROW_MISSED:
        break;
      case err instanceof RanAwayError:
        throw (err.addSeverity(bugsy.SYSLOG_EMERGENCY));
      default:
        throw err;
    }
  }
});
