Themes can be used to change the default styles for all the ReactiveSearch components. These include basic styles like fonts, colors or component styles. The component styles are applied to most of the components.


ReactiveBase acts as the theme provider for all the child ReactiveSearch components. It supports a theme prop which accepts an object with the following defaults:

  typography: {
      fontFamily: '-apple-system, BlinkMacSystemFont, "Segoe UI", "Roboto", "Noto Sans", "Ubuntu", "Droid Sans", "Helvetica Neue", sans-serif',
      fontSize: '16px',

  colors: {
    textColor: '#424242',
    primaryTextColor: '#fff',
    primaryColor: '#0B6AFF',
    titleColor: '#424242',
    alertColor: '#d9534f',


You can overwrite the aforementioned default styles by providing the respective key/values as theme prop. The supported keys are typography, colors and component. For example:

      typography: {
          fontFamily: 'Raleway, Helvetica,      sans-serif',
      colors: {
          primaryColor: '#008000',
          titleColor: 'white',
      component: {
          padding: 10
  <Component1 .. />
  <Component2 .. />
