Who is this presentation for?

  • JavaScript engineers

Prerequisite knowledge

  • A working knowledge of how to code in JavaScript

What you'll learn

  • Learn how to optimize your webpack and Babel configs in order to get the best performance possible

Description

After three years of tooling around with webpack and Babel at Netflix, LinkedIn, and Reddit, Brian Holt has gained some battle-won knowledge. Brian demonstrates how to squeeze more performance out of your code without rewriting it by tweaking webpack and Babel. These tools are immensely powerful, but it’s a delicate dance to get them to play nice.

Join in to learn some nonintuitive tricks that lead to smaller bundles, faster parse times, faster browser-engine opts and de-opts, and faster perceived load times. The session will use Preact, but the lessons apply to any application that uses webpack and Babel. You’ll be surprised at what you can do just by turning a few knobs.
