Storybook Docs w/ CRA & TypeScript

This is a quick-and-dirty walkthrough to set up a fresh project with Storybook Docs, Create React App, and TypeScript. If you're looking for a tutorial, please see Design Systems for Developers, which goes into much more depth but does not use Typescript.

The purpose of this walkthrough is a streamlined Typescript / Docs setup that works out of the box, since there are countless permutations and variables which can influence docs features, such as source code display, docgen, and props tables.

Step 1: Initialize CRA w/ TS

npx create-react-app cra-ts --template typescript

What forces layout / reflow

All of the below properties or methods, when requested/called in JavaScript, will trigger the browser to synchronously calculate the style and layout*. This is also called reflow or layout thrashing, and is common performance bottleneck.

Generally, all APIs that synchronously provide layout metrics will trigger forced reflow / layout. Read on for additional cases and details.

Element APIs

Getting box metrics

• elem.offsetLeft, elem.offsetTop, elem.offsetWidth, elem.offsetHeight, elem.offsetParent
