The QuickBlox UIKit for React allows you to create your own unique view of the UIKit.

​
Default themes

The QuickBlox UIKit for React has 2 built in themes: Dark and Light.

​
Color Theme

Default theme for UIKit is Light. To set theme you need to set value ‘dark’ to key data-theme in global styles (html[data-theme=“dark”]). For example, you can use pure JavaScript:
JavaScript
document.documentElement.setAttribute('data-theme', 'dark');

​
Use your own theme

There are two options how you can create your own theme:
  • Customize current theme using css
  • Create your own theme to customize selected components
To customize the current theme you just need to set the new colors in css variables. Or you can create your own theme. To do this you need to create a new class that implements the UiKitTheme interface. To use your own theme using css you need to create _theme_colors_scheme.scss and set colors

To use your own new theme colors create _theme_dark.scss and _theme_light.scss files and set color variable.
SCSS
// _theme_dark.scss:

html[data-theme="dark"]{
  --color-background-info: #{$primary-500};
  --tertiary-elements: #{$background-overlay-dark};
  --main-elements: #{$primary-300};
  --secondary-elements: #{$primary-a-100};
  --input-elements: #{$secondary-200};
  --disabled-elements: #{$secondary-300};
  --field-border: #{$secondary-200};
  --main-text: #{$primary-a-100};
  --secondary-text: #{$secondary-200};
  --caption: #{$secondary-100};
  --main-background: #{$secondary-500};
  --secondary-background: #{$secondary-800};
  --incoming-background: #{$secondary-400};
  --outgoing-background: #{$primary-500};
  --dropdown-background: #{$secondary-400};
  --chat-input: #{$secondary-800};
  --divider: #{$secondary-400};
  --error: #{$error-300};
  --hightlight: #{$highlight};
}

// _theme_light.scss:
:root{
  --color-background-info:#{$primary-100};
  --tertiary-elements: #{$secondary-300};
  --main-elements: #{$primary-500};
  --secondary-elements: #{$secondary-500};
  --input-elements: #{$secondary-500};

  --field-border: #{$secondary-200};
  --main-text: #{$secondary-900};
  --secondary-text: #{$secondary-300};
  --caption: #{$secondary-200};
  --main-background: #{$primary-a-100};
  --secondary-background: #{$primary-a-100};
  --secondary-background-modal: #{$background-overlay-light};
  --incoming-background: #{$secondary-50};
  --outgoing-background: #{$primary-50};
  --dropdown-background: #{$primary-a-100};
  --chat-input: #{$primary-a-200};
  --divider: #{$primary-50};
  --error: #{$error-500};
  --hightlight: #{$highlight};
}
To create your own theme to customize selected components you need to create a new class that implements the UiKitTheme interface.
TypeScript
//DefaultTheme implements UiKitTheme
export default class CustomTheme extends DefaultTheme {
  divider = (): string => 'var(--divider)';
  mainText = (): string => '#FFFFFF';
  fontFamily = (): string => 'Roboto';
  /*
  The DefaultTheme contains other theme methods :
  caption = (): string => 'var(--caption)';
  chatInput = (): string => 'var(--chat-input)';
  disabledElements = (): string => 'var(--disabled-elements)';
  dropdownBackground = (): string => 'var(--dropdown-background)';
  error = (): string => 'var(--error)';
  fieldBorder = (): string => 'var(--field-border)';
  hightlight = (): string => 'var(--hightlight)';
  incomingBackground = (): string => 'var(--incoming-background)';
  inputElements = (): string => 'var(--input-elements)';
  mainBackground = (): string => 'var(--main-background)';
  mainElements = (): string => 'var(--main-elements)';
  outgoingBackground = (): string => 'var(--outgoing-background)';
  secondaryBackground = (): string => 'var(--secondary-background)';
  secondaryElements = (): string => 'var(--secondary-elements)';
  secondaryText = (): string => 'var(--secondary-text)';
  */
}
and specify selected components:
  • desktop layout container
TypeScript
<QuickBloxUIKitDesktopLayout theme={new CustomTheme()}>
  • header of dialogs
TypeScript
<HeaderDialogs title="Dialog 2" theme={new CustomTheme()}/>
  • item of dialogs
TypeScript
<PreviewDialog
  theme={{ selected: true, muted: true, colorTheme={new CustomTheme()} }}
  title="Dialog with states"
  unreadMessageCount={9}
  message_date_time_sent="5 min ago"
/>
