generic-errors

Generic error constructors with common http codes.

Also doesn't pollute the stack with its own depth.

Usage

Install:

``
npm install generic-errors
`

Require the errors:

`JavaScript
const errors = require('generic-errors');
`

Use an error:

`JavaScript
const notFound = new errors.NotFound('Could not find the thing');
`

Add additional Properties to the error

`JavaScript
const unprocessable = new errors.Unprocessable({ message: 'Cant Process', fields: ['foo', bar] });
`

Detection

After serialization Generic Errors can still be detected using the isGenericError function attacted to the BaseError constructor.

`JavaScript
const notFound = new errors.NotFound();
const serializedError = JSON.parse(JSON.stringify(notFound));

errors.BaseError.isGenericError(serializedError); // true
