    description: 'Bar \'{{foo}}\'',

Documentation

Creating an error

Creating an error can be done by using the createError(type, errorList = []) function.

Example

import SimpleCustomErrors from 'simple-custom-errors';

SimpleCustomErrors.createError("ErrorName", [
  {
    code: 'ErrorCode',
    description: 'Error description with {{details}}',
    details: [
      'details'
    ],
  }
])

Using a custom error

When an error is created, it's time to use such an error. This can be done in two ways.

Example

// Use the CustomError variable
import SimpleCustomErrors from 'simple-custom-errors';
throw new SimpleCustomErrors.Errors.ErrorName('ErrorCode', { variable: 'foo' });

// Use the Errors directly
import { Errors } from 'simple-custom-errors';
throw new Errors.ErrorName('ErrorCode', { variable: 'foo' });

This library is a work in progress, there isn't much more functionality than this...
