# or
npm install @gorhom/animated-tabbar

Also, you need to install react-native-reanimated, react-native-gesture-handler & react-native-svg, and follow their installation instructions.

Usage

Originally Animated TabBar worked only with React Navigation, but I notice that it could be use as a standalone component and be more useful for the community.

Now the library export two main components:

• AnimatedTabBar ( default ) : the React Navigation integrated tab bar.
• AnimatedTabBarView: the standalone tab bar.

Standalone Component

import React, { useState } from 'react';
import { View, Text, StyleSheet } from 'react-native';
import AnimatedTabBar, {TabsConfig, BubbleTabBarItemConfig} from '@gorhom/animated-tabbar';

const tabs: TabsConfig<BubbleTabBarItemConfig> = {
  Home: {
    labelStyle: {
      color: '#5B37B7',
    },
    icon: {
      component: /* ICON COMPONENT */,
      activeColor: 'rgba(91,55,183,1)',
      inactiveColor: 'rgba(0,0,0,1)',
    },
    background: {
      activeColor: 'rgba(223,215,243,1)',
      inactiveColor: 'rgba(223,215,243,0)',
    },
  },
  Profile: {
    labelStyle: {
      color: '#1194AA',
    },
    icon: {
      component: /* ICON COMPONENT */,
      activeColor: 'rgba(17,148,170,1)',
      inactiveColor: 'rgba(0,0,0,1)',
    },
    background: {
      activeColor: 'rgba(207,235,239,1)',
      inactiveColor: 'rgba(207,235,239,0)',
    },
  },
};

const styles = StyleSheet.create({
  container: {
    flex: 1,
    justifyContent: 'center',
    alignItems: 'center',
    backgroundColor: '#999',
  },
  tabBarContainer: {
    borderRadius: 25,
  },
});

export default function App() {
  const [index, setIndex] = useState(0);
  return (
    <View style={styles.container}>
      <Text>{index}</Text>
      <AnimatedTabBarView
        tabs={tabs}
        itemOuterSpace={{
          horizontal: 6,
          vertical: 12,
        }}
        itemInnerSpace={12}
        iconSize={20}
        style={styles.tabBarContainer}
        index={index}
        onIndexChange={setIndex}
      />
    </View>
  )
}

React Navigation v5 (TypeScript)

import React from 'react';
import { NavigationContainer } from '@react-navigation/native';
import { createBottomTabNavigator } from '@react-navigation/bottom-tabs';
import AnimatedTabBar, {TabsConfig, BubbleTabBarItemConfig} from '@gorhom/animated-tabbar';

const tabs: TabsConfig<BubbleTabBarItemConfig> = {
  Home: {
    labelStyle: {
      color: '#5B37B7',
    },
    icon: {
      component: /* ICON COMPONENT */,
      activeColor: 'rgba(91,55,183,1)',
      inactiveColor: 'rgba(0,0,0,1)',
    },
    background: {
      activeColor: 'rgba(223,215,243,1)',
      inactiveColor: 'rgba(223,215,243,0)',
    },
  },
  Profile: {
    labelStyle: {
      color: '#1194AA',
    },
    icon: {
      component: /* ICON COMPONENT */,
      activeColor: 'rgba(17,148,170,1)',
      inactiveColor: 'rgba(0,0,0,1)',
    },
    background: {
      activeColor: 'rgba(207,235,239,1)',
      inactiveColor: 'rgba(207,235,239,0)',
    },
  },
};

const Tab = createBottomTabNavigator();

export default function App() {
  return (
    <NavigationContainer>
      <Tab.Navigator
        tabBar={props => (
          <AnimatedTabBar tabs={tabs} {...props} />
        )}
      >
        <Tab.Screen
          name="Home"
          component={HomeScreen}
        />
        <Tab.Screen
          name="Profile"
          component={ProfileScreen}
        />
      </Tab.Navigator>
    </NavigationContainer>

Props

Preset Configurations

Some presets will have its own configurations - like material - which they will be added the root view props.

Material Preset Example

notice here we added animation, inactiveOpacity & inactiveScale to the root view.

import React from 'react';
import { NavigationContainer } from '@react-navigation/native';
import { createBottomTabNavigator } from '@react-navigation/bottom-tabs';
import AnimatedTabBar, {TabsConfig, MaterialTabBarItemConfig} from '@gorhom/animated-tabbar';

const tabs: TabsConfig<MaterialTabBarItemConfig> = {
Home: {
  icon: {
    component: /* ICON COMPONENT */,
    color: 'rgba(255,255,255,1)',
  },
  ripple: {
    color: '#5B37B7',
  },
},
Profile: {
  icon: {
    component: /* ICON COMPONENT */,
    color: 'rgba(255,255,255,1)',
  },
  ripple: {
    color: '#1194AA',
  },
},
};

const Tab = createBottomTabNavigator();

export default function App() {
return (
  <NavigationContainer>
    <Tab.Navigator
      tabBar={props => (
        <AnimatedTabBar
          tabs={tabs}
          animation="iconWithLabelOnFocus"
          inactiveOpacity={0.25}
          inactiveScale={0.5}
          {...props}
        />
      )}
    >
      <Tab.Screen
        name="Home"
        component={HomeScreen}
      />
      <Tab.Screen
        name="Profile"
        component={ProfileScreen}
      />
    </Tab.Navigator>
  </NavigationContainer>
)
}

Presets

Originally Animated TabBar started with Bubble as the only animation preset embedded. However, I felt the library structure could include many other variety of animation presets.

Bubble Preset

Flashy Preset

Material Preset

Migration

V1 to V2

Due to extend the library functionality, I had to rename existing interfaces as following:

• BubbleTabConfig to BubbleTabBarItemConfig
• BubbleTabIconProps to BubbleTabBarIconProps
• FlashyTabConfig to FlashyTabBarItemConfig
• FlashyTabIconProps to FlashyTabBarIconProps

To Do

• Add accessibility support.
• Add more presets (PR are welcome).
