There are several open-source packages of UI components available:

@dxos/react-uiopen in new windowA set of lookless components in a UI system based on radix, phosphor, react, and tailwind.Any react application.
@dxos/react-ui-themeopen in new windowA default theme for DXOS UIAny react application.
@dxos/react-ui-typesopen in new windowTypeScript types for the UI system.Any react application using DXOS UI.
@dxos/react-ui-editoropen in new windowA collaborative rich text editor component.Any react application using DXOS UI (and/or ECHO).
@dxos/react-ui-mosaicopen in new windowDrag and drop utilities.Any react application using DXOS UI (and/or ECHO).
@dxos/react-ui-tableopen in new windowA data table component.Any react application using DXOS UI (and/or ECHO).

DXOS UI Installation

Install the @dxos/react-ui package with your package manager and follow steps below.


Apps based on the DXOS application templates have DXOS UI configured by default, which can be turned off with --interactive mode.

With Viteopen in new window

Install with Vite

Configure the ThemePlugin in vite.config.jsopen in new window:

import { defineConfig } from 'vite';
import { resolve } from 'node:path';
import { ThemePlugin } from '@dxos/react-ui-theme/plugin';

export default defineConfig({
  plugins: [
      content: [
        resolve(__dirname, './index.html'),
        resolve(__dirname, './src/**/*.{js,ts,jsx,tsx}')

The content array should contain globs that match any other code which will contain tailwind css classes.

Import the special DXOS theme stylesheet @dxosTheme anywhere in code such as main.tsx:

import '@dxosTheme';

import React from 'react';
import { createRoot } from 'react-dom/client';



For best results, load @dxosTheme ahead of any other stylesheets.

With other bundlers

Install with other bundlers

The special @dxosTheme import will not be a available. Include the following stylesheet in your index.html:


This package exports both CJS and ESM builds of its components, though these are styled with Tailwind as the design token system. Any build stack can use the component builds in this package, you’ll just need to configure your build to handle Tailwind so that styles are applied correctly.

Follow the Tailwind Framework Guides documentationopen in new window relevant to your stack to see how that’s done, but make the following modifications:

  • Use the Tailwind configuration from this package:
import tailwindcss from 'tailwindcss';
import { tailwindConfig } from '@dxos/react-components';
// ...
    content: [
      /* Wherever else Tailwind utility classes are used */
    /* Optional params as neeeded */
// ...
  • Instead of adding the Tailwind directives to your own CSS, use or import this package’s theme.css (@dxos/react-ui/dist/plugin/node/theme.css) which adds the Tailwind directives itself.
  • This package relies on font assets installed via npm as dependencies; if you’re seeing errors in the browser console or build logs about missing .woff2 files, ensure your build can correctly resolve the import directives used in theme.css e.g. @import '@fontsource/roboto-flex/variable-full.css'.

Add peer dependencies

This package uses icons from phosphor-icons, but lists them as a peer dependency to avoid re-exporting that package; use your project’s package manager to add phosphor-icons as a dependency.


To use DXOS UI components, wrap your app with a <ThemeProvider /> component:

import React from 'react';
import { render } from 'react-dom';

import { ThemeProvider } from '@dxos/react-ui';

    {/* your components using react-ui here */}

Dark and Light modes

Dark and Light modes are controlled by the application of the dark class.


To prevent flash of unstyled content, ensure the document features the right class ahead of first render. Include the below initializing code in the <head> of your document to achieve this.

    function setTheme(darkMode) {
      document.documentElement.classList[darkMode ? 'add' : 'remove']('dark')
    setTheme(window.matchMedia('(prefers-color-scheme: dark)').matches)
    window.matchMedia('(prefers-color-scheme: dark)').addEventListener('change', function (e) {

Note that you can apply this classname selectively further down the DOM tree if needed.
