dunno

Got weird user complaint but can't reproduce?

Dunno?

• dunno what user did, where he clicked, on which pages?
• dunno where he was 5 sec ago? maybe JS errors 10 sec ago?
• dunno the root cause?

Do know!

Dunno gives you steps to reproduce. Add dunno.js to the page, or require for browserify

npm install dunno
var dunno = require('dunno');

Start tracking asap

dunno.start(); // opts {limit: 10, urlcheck: 100}

window.onerror = function() {
  console.log(dunno.tell());
};

User jumps between pages, does weird stuff, gets an error. Dunno tells you why.

error: Uncaught ReferenceError: invoiceState is not defined

Just post dunno.tell() to LogEntries or whatever you use. Now you know!
