React Native Adding Icons at the Bottom of Tab Navigation

In this section, we will add the icons to the bottom of Tab Navigation. Before dive in this tutorial, go through the previous tutorial Tab Navigation, where we describe how to implement Bottom Tab Navigation.

Example to Add Icons at the Bottom of Tab Navigation

First add the required library and dependency to the React Native project:
1. Add the react navigation library by using the following command:


  1. yarn add react-navigation  
2. Add the react native gesture handler library by using the following command:

  1. yarn add react-native-gesture-handler  
3. Add the react native vector icons library by using the following command:

  1. yarn add react-native-vector-icons  
After the successful execution of above command, link these libraries to react native project using the bellow command:

  1. react-native link  
The above command adds the below dependencies 
in D:\your_directory\your_reactNativeProject\package.json file.

  1. "react-native-gesture-handler": "^1.1.0",  
  2. "react-native-vector-icons": "^6.3.0",  
  3. "react-navigation": "^3.3.2"  
D:\your_directory\your_reactNativeProject\android\app\build.gragle

  1. implementation project(':react-native-vector-icons')  
  2. implementation project(':react-native-gesture-handler')  
D:\your_directory\your_reactNativeProject\android\settings.gradle file:

  1. include ':react-native-vector-icons'  
  2. project(':react-native-vector-icons').projectDir = new File(rootProject.projectDir, '..\node_modules\react-native-vector-icons\android')  
  3. include ':react-native-gesture-handler'  
  4. project(':react-native-gesture-handler').projectDir = new File(rootProject.projectDir, '..\node_modules\react-native-gesture-handler\android')  
Make slightly change (replace '\' with '/') in above route structures as:

  1. include ':react-native-vector-icons'  
  2. project(':react-native-vector-icons').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-vector-icons/android')  
  3. include ':react-native-gesture-handler'  
  4. project(':react-native-gesture-handler').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-gesture-handler/android')  
D:\your_directory\your_reactNativeProject\android\app\src\main\java\com\ reactNativeProject\MainApplication.java

  1. import com.oblador.vectoricons.VectorIconsPackage;  
  2. import com.swmansion.gesturehandler.react.RNGestureHandlerPackage;  
  3. . . .  
  4. protected List<ReactPackage> getPackages() {  
  5.   return Arrays.<ReactPackage>asList(  
  6.       new MainReactPackage(),  
  7.         new VectorIconsPackage(),  
  8.         new RNGestureHandlerPackage()  
  9.   );  
  10. }  

App.js

Create two classes "HomeScreen" and "ProfileScreen" for two tab "Home" and "Profile" respectively. The createBottomTabNavigator function creates a tab bar on the bottom of the screen which provides you to switch between different routes.
Map the "HomeScreen" to "Home" and "ProfileScreen" to "Profile" title. The Icon tag adds the icon to tabs navigation. We can use the different icon name from ionicons.com

  1. import React from 'react';  
  2. import {StyleSheet, Text, View} from 'react-native';  
  3. import { createBottomTabNavigator, createAppContainer } from 'react-navigation';  
  4. import Icon from 'react-native-vector-icons/Ionicons';  
  5. class HomeScreen extends React.Component {  
  6.   render() {  
  7.     return (  
  8.         <View style={styles.container}>  
  9.           <Text>Home Screen</Text>  
  10.         </View>  
  11.     );  
  12.   }  
  13. }  
  14. class ProfileScreen extends React.Component {  
  15.   render() {  
  16.     return (  
  17.         <View style={styles.container}>  
  18.           <Text>Profile Screen</Text>  
  19.         </View>  
  20.     );  
  21.   }  
  22. }  
  23.   
  24. const TabNavigator = createBottomTabNavigator(  
  25.     {  
  26.       Home:{  
  27.         screen:HomeScreen,  
  28.         navigationOptions:{  
  29.           tabBarLabel:'Home',  
  30.           tabBarIcon:({tintColor})=>(  
  31.               <Icon name="ios-home" color={tintColor} size={25}/>  
  32.           )  
  33.         }  
  34.       },  
  35.       Profile: {  
  36.         screen:ProfileScreen,  
  37.         navigationOptions:{  
  38.           tabBarLabel:'Profile',  
  39.           tabBarIcon:({tintColor})=>(  
  40.               <Icon name="ios-person" color={tintColor} size={25}/>  
  41.           )  
  42.         }  
  43.       },  
  44.     },  
  45.     {  
  46.       initialRouteName: "Home"  
  47.     },  
  48. );  
  49. const styles = StyleSheet.create({  
  50.   container: {  
  51.     flex: 1,  
  52.     justifyContent: 'center',  
  53.     alignItems: 'center'  
  54.   },  
  55. });  
  56.   
  57. export default createAppContainer(TabNavigator);  

Output:

16 AWS Gotchas

16 AWS Gotchas In January I launched the MVP for my own startup,  Proximistyle , which helps you find what you’re looking for nearby. On advice from friends and industry contacts I chose AWS as my cloud provider. Having never had to set up my own cloud infrastructure before, the learning curve to get from no experience to a stable VPC system I was happy with was significantly steeper than expected, and had its fair share of surprises. #1 Take advantage of the free resources offered AWS offers a free tier for new accounts. If you have recently bought a domain and set up a company you qualify for the free tier for a year. Additionally, if you are a bootstrapped startup you can apply for  the Startup Builders package  and get $1000 in AWS credits. After doing the above, you’re now ready to get started with setting up the AWS infrastructure for your startup. #2 Set up billing budgets and alerting The very first thing you should do after setting up billing, is enabling a budge...

Ultimate Folder Structure For Your React Native Project

  Ultimate Folder Structure For Your React Native Project React native project structure React Native is a flexible framework, giving developers the freedom to choose their code structure. However, this can be a double-edged sword for beginners. Though it offers ease of coding, it can soon become challenging to manage as your project expands. Thus, a structured folder system can be beneficial in many ways like better organization, simplified module management, adhering to coding practices, and giving a professional touch to your project. This write-up discusses a version of a folder arrangement that I employ in my React Native projects. This structure is based on best practices and can be modified to suit the specific needs of your project. Before we get into the project structure let’s give credit to @sanjay who has the original idea of the structure but I modify his version of the code, to make it better. Base library axios  — For network calling. react-navigation ...

Master Map & Filter, Javascript’s Most Powerful Array Functions

Master Map & Filter, Javascript’s Most Powerful Array Functions Learn how Array.map and Array.filter work by writing them yourself This article is for those who have written a  for  loop before, but don’t quite understand how  Array.map  or  Array.filter  work. You should also be able to write a basic function. By the end of this, you’ll have a complete understanding of both functions, because you’ll have seen how they’re written. Array.map Array.map  is meant to transform one array into another by performing some operation on each of its values. The original array is left untouched and the function returns a new, transformed array. For example, say we have an array of numbers and we want to  multiply each number by three . We also don’t want to change the original array. To do this without  Array.map , we can use a standard for-loop. for-loop var originalArr = [1, 2, 3, 4, 5]; var newArr = []; for(var i = 0; i < originalArr.length; i+...
