Add NPM Package

To add Looker UI Components to your project, add the NPM package to your project:

# Looker projects generally utilize Yarn (
yarn add @looker/components styled-components react react-dom
# If you prefer you can of course also use NPM directly:
npm install @looker/components styled-components

Using Typescript?

If you're using Typescript you'll also need to add the type definitions for Styled Components.

yarn add --dev @types/styled-components @types/react @types/react-dom

Unfortunately, due to this issue with the type definitions for Styled Components you'll need to apply a minor workaround if you're using ESLint along with Styled Component's Typescript definitions.

rm -R node_modules/@types/react-native
echo '@types/react-native' > .yarnclean


@looker/components expects two prerequisites to exist for the complete styling to be applied:


At the top-most level of the usage of @looker/components you need to load the <GlobalStyle /> component. This will inject a simple CSS reset as well as basic font assignment. GlobalStyle documentation

NOTE: The ComponentsProvider will automatically load the GlobalStyle component for you.

Web Font Loading

Users may not have the @looker/components default font, Open Sans, installed on their computers so we recommend importing the font to ensure that content is rendered with the proper font-face.

The simplest way to accomplish this is via Google's hosted CDN:


Using a Component

Now that we have @looker/components installed we can start using them in our application. To get things started import some components:

import { Card, ComponentsProvider, theme } from '@looker/components'
<Card>{Source here...}</Card>

Which could be used to render the following:

Try editing the code above, you should see the changes appear live.

These live editing blocks are found throughout our style guide documentation, providing a space for rapid experimentation with components.
