Package Exports

error-ex

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (error-ex) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Easily subclass and customize new Error types

Examples

To include in your project:

var errorEx = require('error-ex');

To create an error message type with a specific name (note, that ErrorFn.name will not reflect this):

var JSONError = errorEx('JSONError');

var err = new JSONError('error');
err.name; //-> JSONError
throw err; //-> JSONError: error

To add a stack line:

var JSONError = errorEx('JSONError', {fileName: errorEx.line('in %s')});

var err = new JSONError('error')
err.fileName = '/a/b/c/foo.json';
throw err; //-> (line 2)-> in /a/b/c/foo.json

To append to the error message:

var JSONError = errorEx('JSONError', {fileName: errorEx.append('in %s')});

var err = new JSONError('error');
err.fileName = '/a/b/c/foo.json';
throw err; //-> JSONError: error in /a/b/c/foo.json
