From Require.js to Webpack - Part 2 (the how)
View blog-webpack-2.md

This is the follow up to a post I wrote recently called From Require.js to Webpack - Party 1 (the why) which was published in my personal blog.

In that post I talked about 3 main reasons for moving from require.js to webpack:

  1. Common JS support
  2. NPM support
  3. a healthy loader/plugin ecosystem.

Here I'll instead talk about some of the technical challenges that we faced during the migration. Despite the clear benefits in developer experience (DX) the setup was fairly difficult and I'd like to cover some of the challanges we faced to make the transition a bit easier.

So you want to publish a react component?!

This is a quick guide of what you need to do to publish a react component for use by others. This guide is distilled from a conversation [0] on twitter. I will reference individual tweets, where appropriate (thereby shifting blame for incorrect advice from me to the authors :D)

Assumptions

  1. You are using some sort of module system in your source
  2. You have a build step
  3. You want broad support for your component (browser-ready, npm compatible, consumable by bower)

This is a redux-auth concept

This gist is about token-based authentication (who you are?) with redux

Currently it for clent-side apps only. Not for universall (isomorphic) apps. Will add it soon

I'm using the promise middleware to dispatch actions like this:

Dispatching action creators comparison
View dispatching-action-creators.js
// approach 1: define action object in the component
this.props.dispatch({
type : "EDIT_ITEM_ATTRIBUTES",
payload : {
item : {itemID, itemType},
newAttributes : newValue,
}
});
// approach 2: use an action creator function

JavaScript preprocessing/precompilation
View preprocessing.md

Problem: How can we preprocess JavaScript (at build-time or on the server-side) so engines like V8 don't have to spend as much time in Parse? This is a topic that involves generating either bytecode or a bytecode-like-abstraction that an engine would need to accept. For folks that don't know, modern web apps typically spend a lot longer in Parsing & Compiling JS than you may think.

  • Yoav: This can particularly be an issue on mobile. Same files getting parsed all the time for users. Theoretically if we moved the parsing work to the server-side, we would have to worry about it less.
  • One angle to this problem is we all ship too much JavaScript. That's one perspective. We could also look at preprocessing.
  • We've been talking about this topic over the last few weeks a bit with V8. There were three main options proposed.
    1. Similar to what optimize-js does. Identify IIFEs and mark them as such so the browser and VMs heuristics will catch them and do a better job than today. optimize-js only tackles IIFE bu

How to use profiling in production mode for react-dom
View index.md

React recently introduced an experimental profiler API. This page gives instructions on how to use this API in a production release of your app.

Table of Contents

Profiling in production

React DOM automatically supports profiling in development mode for v16.5+, but since profiling adds some small additional overhead it is opt-in for production mode. This gist explains how to opt-in.

View App.js
import React from "react";
import useMutableReducer from "./useMutableReducer";
const reducer = (draft, action, state) => {
switch (action) {
case "increment":
draft.count++;
break;
case "decrement":
draft.count--;
