Package Exports

string-error-parse

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 (string-error-parse) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

string-error-parse

This module parses the error message (string) of node.js.

This is very useful when you check for errors, for example, in a child process that cannot be verified by a previous instance of Error. Unlike stack-trace module, this module is only focused on interpreting string errors.

Install

npm install string-error-parse
