errsome's Introduction

errsome

Making errors more loggable, readable and serializable, but still object.

Why?

There is some problems with Error object in node.js, so why not try to handle it?

Usage

const errsome = require('errsome');

const err = new Error('Bla-bla-bla');

const awesomeError = errsome(err);

const serializedError = errsome.stringify(err, 2);
// It is just a short form for this:
// require('json5').stringify(err, null, 2);

errsome.log(err, 2);
// It is just a short form for this:
// console.log(errsome.stringify(err, 2));
