Announcing NativeBase v3.0!

Announcing NativeBase v3.0!

Mobile-first, accessible components for React Native & Web.

We really didn’t know we would come this far with a UI component library for React Native. We built a starter-kit for React Native back in 2016 and later pulled out reusable components in a separate library that we called NativeBase. The first version was just a bunch of components bundled together in an NPM package. The v2.0 was quite an improvement considering the platform level design philosophies of Material and Cupertino design.

Things have evolved since then, with over 55,000 dependent projects and almost 16,000 stars on Github we are ready for NativeBase 3.0. The new paradigm of utility-first which makes the components reusable and adheres to a wide spectrum of design is the need of the moment. We have tried our level best to make the library flexible & customizable. But that’s not it, NativeBase v3.0 is now universal, it works on all the platforms; web & mobile. It behaves natively on those platforms with focussed support for accessibility (keyboard, mouse, screen readers). And how can I not mention, it has full support for Dark Mode too. We stand in the middle of a very exciting time in tech when all the platforms are merging and all thanks to React Native & the folks in the community who are making this possible.

We, the NativeBase team, are doing our part to take this journey forward that would eventually help millions build quality software faster.

What’s new and improved?


Based on the Styled System Theme specification, NativeBase 3.0 has highly themeable core components where you define your app’s color palette, type scale, font stacks, breakpoints, border-radius values, and more with ease. The only limitation is your imagination!

Out of the box Accessibility

Integrated with React ARIA and React Native ARIA, which provides React hooks, this feature enables you to build accessible design systems in no time. The customizability and consistency offered by our framework allows one to code to their heart’s content.


Utility Props

Inspired by Styled System, so you can rapidly build custom UI components with constraint-based utility-style props, has been enhanced to result in expressive and consistent UI components which you can define according to your theme.

  <Text fontWeight="medium" color="white" fontSize="sm">
    Hey There!

Customisable Theme

Theming is one of the core elements of NativeBase. You can customise the theme as per your liking. NativeBase theme is a complex object which can be easily extended and customised.

import React from 'react';
import { NativeBaseProvider, extendTheme } from 'native-base';
import { Content } from './Content';

export default function () {
  const theme = extendTheme({
    colors: {
      // Add new color
      primary: {
        50: '#E3F2F9',
        100: '#C5E4F3',
        200: '#A2D4EC',
        300: '#7AC1E4',
        400: '#47A9DA',
        500: '#0088CC',
        600: '#007AB8',
        700: '#006BA1',
        800: '#005885',
        900: '#003F5E',
      // Redefinig only one shade, rest of the color will remain same.
      amber: {
        400: '#d97706',
    config: {
      // Changing initialColorMode to 'dark'
      initialColorMode: 'dark',

  return (
    <NativeBaseProvider theme={theme}>
      <Content />

Introducing Pseudo Props

Inspired by Chakra and other utility first libraries, we have also provided the support for new Pseudo props that covers various conditional domains like, platforms, color modes, interaction states etc.

    _text: { color: 'secondary.400' },
  Change My Color

Kitchen Sink

To make NativeBase more comprehensible for users, we have also launched a simple demo app showcasing all the NativeBase components in action. Kitchen Sink gives an up-close demonstration of buttons, forms, icons and much more working together.


Rich Component Library

With NativeBase, you are spoilt for choice with over forty components that are pre-provided to enable seamless development. These components include buttons, action sheets, menus, spinners, popovers, breadcrumbs and more.

Rich Component Library

Highly Responsive

NativeBase 3.0 allows you to provide object and array values to add responsive styles. This makes apps highly responsive and ideal for all kinds of display devices, from mobile phones to large desktops.

    w={['24', '48', '72']}
    h={{ base: '24', sm: '48', md: '72' }}
  This is a responsive box

Introducing Dark Mode

NativeBase now supports dark and light themes by default. It just got a whole lot easier to build a dark mode setting for your apps.

function UseColorMode() {
  const { colorMode, toggleColorMode } = useColorMode();
  return (
    <Box flex={1} bg={colorMode === 'dark' ? 'black' : 'coolGray.300'}>
      <Button m={2} ml="auto" onPress={toggleColorMode}>Toggle</Button>
      <Center flex={1}>
          _light={{ bg: 'teal.600', _text: { color: 'white' } }}
          _dark={{ bg: 'amber.500' }}

export default function () {
  return (
      <UseColorMode />

Consistent Across Platforms

Built using the React Native Framework, we are trying to bring to you a native experience that is consistent across all platforms, whether it be iOS, Android or web, making it highly desirable for developers. You can fast-track your dev process with universal components for reliable and organised coding.

The Future of NativeBase 2.0

Over the years, NativeBase has been used as the desired framework for over 50k projects worldwide and we are humbled by the love we’ve received so far, in terms of downloads and starts received on GitHub. With the onset of NativeBase 3.0, we thought it’d be best to slow down NativeBase 2.0 and help users migrate to v3.0. NativeBase 2.0 will still be supported by us for the time being, which means that if your app is dependent on NativeBase 2.0 and you don’t want to upgrade just yet (which you should), you can continue to use it for as long as you like. We will also support critical bug fixes in v2.0 till March 2022.

The NativeBase 2.0 blog, however, is now deprecated but is still available as an archive where you can read about NB 2.0 and everything around the legacy NativeBase. Find it here.

We’re really excited to share NativeBase 3.0 with you and the rest of the community. We really hope that you like it and help us improve it. We also have plans of introducing a starter kit, NativeBase StartUp+, which are over 100+ production-ready UI screens that work on web and native platforms, which will be coming soon. Meanwhile, do follow us on our Discord channel and Twitter for further updates.
