Built a feature
Published an NPM Package
Published stderr-error-parser, a utility library to parse the error stack from the stderr of a Node.js process.

The Node.js process could throw a SyntaxError, TypeError, or any other error and this library will parse the specific error right down to the line number, column number, error name, and the entire error stack.

This utility library was borne out of need in an adjacent project I was working on, Syntasso.
