Gestalt
Gestalt is a set of React UI components that enforces Pinterest’s design language. We use it to streamline communication between designers and developers by enforcing a bunch of fundamental UI components. This common set of components helps raise the bar for UX & accessibility across Pinterest.

Installation
The package can be installed via npm:
npm i gestalt --save
npm i gestalt-datepicker --save
Or via yarn:
yarn add gestalt
yarn add gestalt-datepicker
Usage
Gestalt exports each component as ES6 modules and a single, precompiled CSS file:
import { Text } from 'gestalt';
import 'gestalt/dist/gestalt.css';
That syntax is Webpack specific (and will work with Create React App), but you can use Gestalt anywhere that supports ES6 module bundling and global CSS.
Development
Gestalt is a multi-project monorepo. The docs and components are all organized as separate packages that share similar tooling.
Install project dependencies and run tests:
yarn
yarn test
Build and watch Gestalt & run the docs server:
yarn start
Visit http://localhost:8888/ and click on a component to view the docs.
Codemods
When a release will cause breaking changes — in usage or in typing — we provide a codemod to ease the upgrade process. Codemods are organized by release in /packages/gestalt-codemods
.
Usage
Clone the Gestalt repo locally if you haven't already. Run the relevant codemod(s) in the relevant directory of your repo (not the Gestalt repo): anywhere the component to be updated is used. Example usage for a codebase using Flow:
yarn codemod --parser=flow -t={relative/path/to/codemod} relative/path/to/your/code
For a dry run to see what the changes will be, add the -d
(dry run) and -p
(print output) flags (pipe stdout to a file for easier inspection if you like).
