Send your first message

The QuickBlox UIKit for React comprises a collection of pre-assembled UI components that enable effortless creation of an in-app chat equipped with all the necessary messaging functionalities. Our development kit encompasses light and dark themes, colors, and various other features. These components can be personalized to fashion an engaging messaging interface that reflects your brand's distinct identity.

The QuickBlox UIKit fully supports both private and group dialogs. To initiate the process of sending a message from the ground up using Java or Kotlin, please refer to the instructions provided in the guide below.


The minimum requirements for QuickBlox UIKit for React are:

  • JS QuickBlox SDK v2.15.5
  • React v.18.0
  • TypeScript v.4.9.3

Before you begin

Register a new account following this link. Type in your email and password to sign in. You can also sign in with your Google or Github accounts.
Create the app clicking New app button.
Configure the app. Type in the information about your organization into corresponding fields and click Add button.
Go to Dashboard => YOUR_APP => Overview section and copy your Application ID, Authorization Key, Authorization Secret, and Account Key .

Install QuickBlox SDK

npm install quickblox

Install QuickBlox UIKit

npm install quickblox-react-ui-kit

Init QuickBlox SDK

To init QuickBlox SDK you need to pass Application ID, Authorization Key, Authorization Secret, and Account Key to the init() method.

var AUTH_KEY = "lkjdueksu7392kj";
var AUTH_SECRET = "iiohfdija792hj";
var ACCOUNT_KEY = "sdjfnksnlk2bk1k34kb";
var CONFIG = { debug: true };




It's not recommended to keep your authKey and authSecret inside an application in production mode, instead of this, the best approach will be to store them on your backend. Instead you can initialize QuickBlox SDK without Authorization Key and Secret


Before sending your first message you need to authenticate users in the QuickBlox system. You can read more about different ways of authentication by this link.
In our example we show how to authenticate user with login and password.

import * as QB from "quickblox/quickblox";
import { QuickBloxUIKitProvider } from 'quickblox-ui-kit-react';

QB.createSession(function(error, result) {
  var params = { login: "garry", password: "garry5santos" };

  QB.login(params, function(error, result) {
    } else {
      // Navigate User to the UIKit

To order to config quickblox ui kit provider

maxFileSize={100 * 1000000} //set max size for attachments
  <Desktop> // container for DesktopLayout


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.
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:

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

$background-overlay-light: rgba(19, 29, 40, .80);
$background-overlay-dark: rgba(144, 151, 159, .80);
$primary-50: #E7EFFF;
$primary-100: #C4D7FE;
$primary-200: #9CBCFE;
$primary-300: #74A1FD;
$primary-400: #578CFC;
$primary-500: #3978FC;

$error-400: #FF584F;
$error-500: #FF3B30;
$information: #FDB0FF;
$highlight: #FFFDC1;

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

// _theme_dark.scss:

  --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:
  --tertiary-elements: #{$secondary-300};
  --main-elements: #{$primary-500};
  --secondary-elements: #{$secondary-500};
  --input-elements: #{$secondary-500};
  --disabled-elements: #{$secondary-100};
  --field-border: #{$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.

//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
<QuickBloxUIKitDesktopLayout theme={new CustomTheme()}>
  • header of dialogs
<HeaderDialogs title="Dialog 2" theme={new CustomTheme()} />
  • item of dialogs
  theme={{ selected: true, muted: true, colorTheme={new CustomTheme()} }}
  title="Dialog with states"
  message_date_time_sent="5 min ago"
