In this article, we are going to see how to implement Tab Navigation in react-native. For this, we are going to use createBottomTabNavigator component. It is basically used for navigation from one page to another. These days mobile apps are made up of a single screen, so create various navigation components in React Native. We want to use React Navigation.

Syntax:

const Tab = createBottomTabNavigator();
<Tab.Navigator >
   <Tab.Screen/>
</Tab.Navigator>

Props in Tab Navigation:

  • initialRouteName: It is the initial route that opens when the application loads.
  • order: It basically sets the order of the tabs.
  • paths: It controls the mapping of the route screen to path config.
  • lazy: If its value is true, then the tab is rendered when it becomes active for the first time. Its default value is true.
  • tabBarComponent: It is an optional prop. It overrides the component which is used as a tab bar.
  • tabBarOptions: It is an object of many properties like tabStyle , showLabel, showIcon, style, etc…

 

Now let’s start with the implementation:

  • Step 1: Open your terminal and install expo-cli by the following command.

    npm install -g expo-cli
  • Step 2: Now create a project by the following command.

    expo init myapp
  • Step 3: Now go into your project folder i.e. myapp

    cd myapp
  • Step 4: Now install react-navigation into your project. React Navigation is used to navigate between one page to another. Install it by using the following command.

    npm install @react-navigation/native
  • Step 5: Now install dependencies into your react-native project by using the following command.

    npm install react-native-reanimated react-native-gesture-handler react-native-screens react-native-safe-area-context @react-native-community/masked-view

  •  

  • Step 6: Now install bottom-tabs from react-navigation.

    npm install @react-navigation/bottom-tabs

For React Tab Navigation: This can be used in React Native as well

Project Structure:

Example: Now let’s implement Tab Navigation.

App.js




import * as React from 'react';
import { Text, View } from 'react-native';
import { NavigationContainer } 
         from '@react-navigation/native';
import { createBottomTabNavigator } 
         from '@react-navigation/bottom-tabs';
  
function Home() {
  return (
    <View style={{ flex: 1, justifyContent: 'center'
                   alignItems: 'center' }}>
      <Text>Home!</Text>
    </View>
  );
}
  
function Setting() {
  return (
    <View style={{ flex: 1, justifyContent: 'center'
                   alignItems: 'center' }}>
      <Text>Settings!</Text>
    </View>
  );
}
  
function Notification() {
  return (
    <View style={{ flex: 1, justifyContent: 'center',
                   alignItems: 'center'}}>
      <Text>Notifications!</Text>
    </View>
  );
}
  
const Tab = createBottomTabNavigator();
  
export default function App() {
  return (
    <NavigationContainer >
      <Tab.Navigator initialRouteName={Home} >
        <Tab.Screen name="Home" component={Home}  />
        <Tab.Screen name="Notifications" 
                    component={Notification} />
        <Tab.Screen name="Settings" component={Setting} />
      </Tab.Navigator>
    </NavigationContainer>
  );
}


Start the server by using the following command.

npm run android

Output: If your emulator did not open automatically then you need to do it manually. First, go to your android studio and run the emulator. Now start the server again.
