@zendeskgarden/react-theming

The Theming package includes several utility components relating to theming and RTL capabilities in the Garden Design System.

Installation

npm install @zendeskgarden/react-theming

# Peer Dependencies - Also Required
npm install react react-dom prop-types styled-components @zendeskgarden/react-theming

Usage

The ThemeProvider component can be used to apply granular theming to Garden (and custom) components as well as providing a RTL context.

It is intended to be used at the root of an application to provide a global context for RTL.

ThemeProvider components can be nested within each other for areas that require additional, custom theming.

Theming

All themes are auto-prefixed and has access to the props provided to the component.

import { ThemeProvider } from '@zendeskgarden/react-theming';
import { Notification, Title, Paragraph } from '@zendeskgarden/react-notifications';

const theme = {
  'notifications.title': `
    && {
      color: red;

      :hover {
        color: blue;
      }
    }
  `,
  'notifications.paragraph': props => (props.purple ? 'color: purple' : '')
};

<ThemeProvider theme={theme}>
  <Notification>
    <Title>Themed Title (hover as well)</Title>
    <Paragraph purple>Custom theme triggered by prop</Paragraph>
  </Notification>
</ThemeProvider>;

RTL

import { ThemeProvider } from '@zendeskgarden/react-theming';
import { Notification } from '@zendeskgarden/react-notifications';

<ThemeProvider rtl>
  <Notification>This notification content will have custom styling.</Notification>
</ThemeProvider>;

The withTheme HOC utility allows any component to interact with its ThemeProvider.

import { withTheme } from '@zendeskgarden/react-theming';

const StyledDiv = ({ theme, children }) => (
  <div style={{ direction: theme.rtl ? 'rtl' : 'ltr' }}>{children}</div>
);

const LocalizedComponent = withTheme(StyledDiv);

<ThemeProvider rtl>
  <LocalizedComponent>RTL localizable</LocalizedComponent>
</ThemeProvider>;

Advanced usage

If you need to compose from other theme overrides e.g. you find yourself overriding the same properties in several components or you're using props to alter your overrides then please see the following code example.

import { ThemeProvider } from '@zendeskgarden/react-theming';
import { Notification, Title, Paragraph } from '@zendeskgarden/react-notifications';
import { css } from 'styled-components';

const commonOverrides = `
  &&:hover {
    color: blue;
  }
`;
const theme = {
  'notifications.title': css`
    ${commonOverrides} && {
      color: red;
    }
  `,
  'notifications.paragraph': css`
    ${commonOverrides} ${props => (props.purple ? 'color: purple' : '')};
  `
};

<ThemeProvider theme={theme}>
  <Notification>
    <Title>Themed Title (hover as well)</Title>
    <Paragraph purple>Custom theme triggered by prop</Paragraph>
  </Notification>
</ThemeProvider>;

The main difference here is the usage of the css helper from styled-components. This will correctly pass down the props from the component so you can conditionally apply styles based on props or compose from other template literals.

Theme ids

Each component has a COMPONENT_ID applied so you can target it in your own theme file to override the default look and feel. This table contains all the ids and which package they apply to.

WARNING

Theming is meant to be used for small, global changes to a component (i.e accent color, padding changes, etc.)

If you find yourself "skinning" a component, it may be much easier (and maintainable) if you were to create these presentation assets as standalone components and use them with our advanced Container abstractions.
