Theme

Pipeline Components come with built-in access to the default Pipeline theme. The theme file contains an object which holds values for common variables such as color, fonts, box shadows, and more.

Strategies

You can override the entire theme for an entire tree of components using the ThemeProvider from styled-components:

import {Box, Button, Text, theme} from 'pipeline-ui'import {ThemeProvider} from 'styled-components'// a theme with custom spacing and font sizesconst customTheme = {  ...theme,  space: [0, 8, 16, 32, 64],  fontSizes: [10, 12, 16, 24, 48]}// overridecustomTheme.colors.black = '#111'export default () => (  <ThemeProvider theme={customTheme}>    <Box color='black' p={4}>      <Text fontSize={4}>Hello, world!</Text>    </Box>  </ThemeProvider>)

Option B: You can merge the pipeline theme with your custom theme using Object.assign:

import {theme} from 'pipeline-ui';import { ThemeProvider } from 'styled-components';const customTheme = {  space: [0, 8, 16, 32, 64],  fontSizes: [10, 12, 16, 24, 48],  colors: {    ...theme.colors,    black: '#111'  }};const App = (props) => {  return (    <div>      <ThemeProvider theme={Object.assign({}, theme, customTheme)}> // matching keys in customTheme will override keys in the pipeline theme        <App />      </ThemeProvider>    </div>  )}

Option 3: You can theme individual components by passing the theme prop directly:

import {Text} from 'pipeline-ui'const customTheme = {  colors: {    magenta: '#f0f'  }}export default () => (  <Text theme={customTheme} color='magenta'>Hi, I'm magenta!</Text>)
