Using CodeMirror to Build a JavaScript Editor with Linting and AutoComplete

Using a library might seem easy at first glance, but how do you choose the right library? How do you upgrade an existing one? And how do you wade through the documentation to find what you want? In this workshop, we’ll discuss all these finer points while going through a general example of building a code editor using CodeMirror in React. All while sharing some of the nuances our team learned about using this library and some problems we encountered.

Production errors can be tricky, especially when you can’t reproduce them easily or they don't happen very often. In this talk, we’ll go through a case study of a quantity mismatch Shopping Cart issue and what troubleshooting steps we took to solve it. Then drawing from that issue some lessons that we can all learn from as frontend developers.
