Just some notes about my attempt to upgrade to webpack 4

If you enjoyed reading this, I'm intending to do more blogging like this over here: https://cdgd.tech

This is not a complaint about Webpack or v4 in any way. This is just a record of my process trying it out so I could provide feedback to the webpack team

Hmm... I don't see any docs for 4.0 on https://webpack.js.org. I guess I'll just wing it. All I need to do is npm i -D webpack@next, right?

+ webpack@4.0.0-beta.2

Debugging

Debugging JavaScript Applications

A practical distillation for Fullstack Academy students

Faults in computer problems were theorized as far back as 1843, when Ada Lovelace noted of Babbage's Analytical Engine, "Granted that the actual mechanism is unerring in its processes, the cards may give it wrong orders." Almost 160 years later, NIST reported that software errors cost the US $59 billion annually. Clearly, some of the cards are wrong. However, unlike Grace Hopper's famous moth, most of the time the culprit is ourselves.

Debugging is a sanitization procedure consisting of:

  • Preventing bugs in the first place, through good practices and assistive tooling.
  • Detecting bugs when they first arise, through proper error handling and testing.

Interaction tracing with React

This API was removed in React 17


Interaction tracing with React

React recently introduced an experimental profiler API. After discussing this API with several teams at Facebook, one common piece of feedback was that the performance information would be more useful if it could be associated with the events that caused the application to render (e.g. button click, XHR response). Tracing these events (or "interactions") would enable more powerful tooling to be built around the timing information, capable of answering questions like "What caused this really slow commit?" or "How long does it typically take for this interaction to update the DOM?".

With version 16.4.3, React added experimental support for this tracing by way of a new NPM package, scheduler. However the public API for this package is not yet finalized and will likely change with upcoming minor releases, so it should be used with caution.

experiment: mimicking React's new "useState()" hook for stand-alone functions, including "custom hooks"
"use strict";
[foo,bar] = TNG(foo,bar);
// NOTE: intentionally not TNG(..) wrapping useBaz(), so that it's
// basically like a "custom hook" that can be called only from other
// TNG-wrapped functions
function foo(origX,origY) {
var [x,setX] = useState(origX);
var [y,setY] = useState(origY);
