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.

View the full docs or Check out the Gestalt playground

Install

npm i gestalt --save or yarn add gestalt

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, components and integration tests 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:3000/ and click on a component to view the docs.

Using the Masonry playground:

cd test && yarn start
open "http://localhost:3001/Masonry"

Running Masonry's integration tests. This will leave lots of Firefox processes hanging around, so please be warned.

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. We recommend using jscodeshift to upgrade.

Prerequisite:

Install jscodeshift globally if you haven't already.

yarn global add jscodeshift

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:

jscodeshift --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).

Releasing

If you haven’t already, you’ll first need to create an npm account. Once you've done that you can setup your username and email in Yarn using yarn login.

The following outlines our release process:

1. Checkout a new branch.
2. Bump package version in packages/gestalt/package.json & update CHANGELOG.md.
3. Open a pull request with the new version and land that in master.
4. Once the version is bumped in master, checkout that commit locally.
5. Run npm login using your npm username and password.
6. Run the release script from the root directory of the project ./scripts/publish.js to publish the tag, npm package, and docs.
7. Draft a new release from the tag at https://github.com/pinterest/gestalt/releases.

Typescript Support

Install the DefinitelyTyped definitions.

npm i --save @types/gestalt
