RunKit + 
Try any Node.js package right in your browser
This is a playground to test code. It runs a full Node.js environment and already has all of npm’s 1,000,000+ packages pre-installed, including serr. Try it out:
// Example to interact with in https://tonicdev.com/npm/serr
var serializeError = require('serr');
var error = new Error('User Not Found');
error.statusCode = 404;
console.log(serializeError(error).toObject());
// ADD stack traces
console.log(serializeError(error).toString(true));
