    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
