Cost to Hire React Native App Developers

React Native is unique because its dynamic code updates, it can push updates to devices without requiring an application release. With React Native you will be able to create Native applications with JavaScript.

React Native is unique because its dynamic code updates, it can push updates to devices without requiring an application release. With React Native you will be able to create Native applications with JavaScript.

The cost of hiring React Native developer will vary according to the certain factors like:

Analysis & Scoping:

  • This helps you to keep a proper document of what the app would do, which kind of features it would have to fulfill its purpose, & which technology it could be used.


Duration & Scope:

  • The major cost will depend on the complexity, scope, requirements of the project & time required to finish it. It's obvious that the cost will be higher of react native developers on the base of projects complications and long time duration to complete it.


Application Complexity:

  • App complexity includes many features such as development architecture, third-party integration, model admin panel, in-app purchase, hardware device used.


Hiring model:

  • There are mainly three types of model which differentiate the cost of hiring react native developers such as part-time, hourly basis, & full time.


Application Category:

  • A category is also one of the important factors which affect the cost of hiring react native developer. While moving from one category to another, a lot of things modify like a number of users, functionalities, security criteria & so on.


Experience & Skills of Developer:

  • If you look for a well experienced react native developer, it will cost you more compared to those developers who are still building his profile because they will cost you less than an experience.
  • Skills are also a major factor because a good skill set of a developer in particular libraries, frameworks, etc will impact your cost of hiring react native developer.


React Native developers must have the required skill set to fulfill your expectations for the app development.

  • Good command over the fundamentals of HTML, CSS, and JavaScript.
  • Familiarity with CSS pre-processors like Sass and LESS.
  • Working knowledge of JavaScript libraries like jQuery or Backbone.js
  • Skills for front-end CSS frameworks like Bootstrap and Foundation.
  • Experience in Unit Testing with React Testing Tools like Karma or Jest.


Application Platform:

  • The number of OS versions and app platforms for your application launched process will decide that how much does it cost to create a react native application.


Android Application: It cost quite higher when there are a number of devices with multiple OS versions

Web Applications: Compare to native apps such as Android & iOS, PWA is much cost effective development cost.

iOS Application: iOS doesn't have any issues regarding OS versions and it uses swift/Object C for app development.

Location for hiring developers:

  • The location also plays a major role in the cost of hiring react native developers, If you hire react native developers from India, it will cost you less compared to the US because salary considerably varies from country to country to country.


Application Development:

  • There are some instances when an application gets rejected and is unable to pass the approval stage because of lacking in development criteria which is checked by app store & play store strict guidelines for the mobile app development process.


Application Maintenance:

  • Support, Testing & Maintenance is a critical task for every mobile application development. Expenses do not come to an end with this last stage of the process.
  • Business will have to continue changing their application to walk with market trend including new device & OS versions. Though it depends who is developing your mobile app, freelancer or a full-time developer so that there will be a cost differentiate for your application development cost.

React Native Vs Native : Which Is The Best For Your Mobile App?

Hence, Native app development needs more time, money, & resources to build an app.


In this article, we are going to find out which is better between React native vs native.

Why Mobile App Developer prefer React Native?

React Native is the latest but very popular technology platform which allows developers to create real mobile apps using only JavaScript. At the same time. Using React Native framework, developers can build cross-platform applications for both Cross-platforms.

How do Navigation for your Mobile app using React Native

How do Navigation for your Mobile app using React Native

In this post, we go through how to implement different types of navigation for your mobile app using React Native.

Introduction

Creating an intuitive navigation UI is essential for any mobile app. Because we build custom software at SmartLogic, most of our mobile apps require different navigation setups, but they often have a lot in common. We use React Navigation which makes it easy for users to move across different screens. Built-in options allow us to quickly add UI features while also being fully customizable. In this post, I'll walk through a basic React Navigation pattern we've used and the steps to get it up and running.

Below is an example of the architecture of common patterns we use. We have the main navigation for our app, different navigation stacks (more on this later), screens and a tab navigation setup as well.

        components
                \
                BackArrow.js
Installation

Installing React Navigation into your project is easy. Here are the main commands to get started.

In your root project directory run:

`yarn add react-navigation`  

If you are using Expo managed workflow you do not need to add the following as it's already included and can skip down to the next section.

**Then:**

yarn add react-native-gesture-handler

**Link RN Gesture Handler by running:** `react-native link react-native-gesture-handler`
**Additional Android Gesture Handler setup:**
Your `MainActivity.java` file should look like the following; you'll need to add the lines that have a +:
package com.reactnavigation.example;

  import com.facebook.react.ReactActivity;
+ import com.facebook.react.ReactActivityDelegate;
+ import com.facebook.react.ReactRootView;
+ import com.swmansion.gesturehandler.react.RNGestureHandlerEnabledRootView;

  public class MainActivity extends ReactActivity {

    @Override
    protected String getMainComponentName() {
      return "Example";
  }

+ @Override
+ protected ReactActivityDelegate createReactActivityDelegate() {
+   return new ReactActivityDelegate(this, getMainComponentName()) {
+     @Override
+     protected ReactRootView createRootView() {
+      return new RNGestureHandlerEnabledRootView(MainActivity.this);
+     }
+   };
+  }
  }
Navigation Architecture

Root Component

App.js is the entry point for the app, it is the top level component. In it we will include a <RootContainer /> component which will hold the app navigation.

file: OurApp/App.js

import React, { Component } from 'react'
import RootContainer from './app/containers/RootContainer'

export default class App extends Component {

  render () {
    return (
      <RootContainer />
    )
  }
}

< Root Container />

Our RootContainer will holds the app's root navigation

file path: OurApp/app/containers/RootContainer.js

import React, { PureComponent } from 'react'
import { StatusBar, View } from 'react-native'
import AppNavigator from '../navigation/AppNavigator'

export default class RootContainer extends PureComponent {

  render () {
    return (
      <View style={{ flex: 1 }}>
        <StatusBar />
        <AppNavigator />
      </View>
    )
  }
}

App Navigator is the base of our app navigation. The initial route is set by initialRouteName and is where the app starts when users first open it. Here we are starting on the HomeStack, which is a nested navigation stack.

Nested navigation stacks, or just stacks, are a way of organizing our screens into groups. We group together screens that follow a common flow as users navigate the app.

We've defined the constant AppNavigator for easy export which uses createStackNavigator() to create routes for each of the stacks we'll use and createAppContainer()to create the navigation container.

App Navigator is our stack navigator. We're essentially creating a stack of all the stacks and then turning it into our main navigation container.

file path: OurApp/app/navigation/AppNavigator.js

import { createStackNavigator, createAppContainer } from 'react-navigation'
import HomeStack from './HomeStack'
import TabNavigator from './TabNavigator'
import ChatStack from './ChatStack'
import TransactionStack from './TransactionStack'

const AppNavigator = createStackNavigator({
  HOME_STACK: {
    screen: HomeStack
  },
  TAB_NAVIGATION: {
    screen: TabNavigator
  }
}, {
  initialRouteName: 'HOME_STACK',
  headerMode: 'none'
})

export default createAppContainer(AppNavigator)

createStackNavigator returns a React component, which we are exporting and use in the <RootContainer />. For organization, I've put my Stack Navigator in a separate file.

In it, I've defined a route for each of the different stacks we have and set the screen of each route to point to the stack component which defines the screens for each stack. We usually put stack names in screaming snake case just for distinction, this is not required.

Individual Stack Components

In each of the stack components, we are linking screens that would logically go together to form a navigation flow.

We use createStackNavigator again to create a route for each screen in the stack. And because we're keeping our route name the same as our screen names, we don't have to set the screen separately.

file: OurApp/app/navigation/HomeStack.js folder:

import { createStackNavigator } from 'react-navigation'
import HomeScreen from '../containers/HomeScreen'
import LoginScreen from '../containers/LoginScreen'
import ImportContactsScreen from '../containers/ImportContactsScreen'

const HomeStack = createStackNavigator({
  HomeScreen,
  LoginScreen,
  ImportContactsScreen
}, {
  initialRouteName: 'HomeScreen',
  headerMode: 'none'
})

export default HomeStack
Tab Navigator

We have relatively few stacks and screens to move through in this app, so we use bottom tab navigation via createBottomTabNavigator() once users are signed in to move through the three main stacks.

We're using icons for users to press to get to each of the three stacks in the tab navigator. The navigator will remain visible at the bottom on each screen the user navigates to.

We define the icons at the top, rendering React Native Vector Icons components, which we've already included in our app and in tabBarOptions we set the active/inactive icon colors which come from the app/themes/Colors file where all of our app colors are defined.

file: OurApp/app/navigation/TabNavigator.js

import React from 'react'
import { createBottomTabNavigator, createAppContainer } from 'react-navigation'
import { Colors } from '../themes'
import Icon from 'react-native-vector-icons/FontAwesome'
import ChatStack from './ChatStack'
import ProfileScreen from '../containers/ProfileScreen'
import TransactionStack from './TransactionStack'

const chatIcon = ({ tintColor }) => (
  <Icon name='comments' size={30} color={tintColor} />
)
const transactionsIcon = ({ tintColor }) => (
  <Icon name='file-text' size={25} color={tintColor} />
)
const profileIcon = ({ tintColor }) => (
  <Icon name='user' size={25} color={tintColor} />
)

const TabNavigator = createBottomTabNavigator({
  CHAT: {
    screen: ChatStack,
    navigationOptions: {
      tabBarIcon: chatIcon
    }
  },
  PROFILE: {
    screen: ProfileScreen,
    navigationOptions: {
      tabBarIcon: profileIcon
    }
  },
  TRANSACTIONS: {
    screen: TransactionStack,
    navigationOptions: {
      tabBarIcon: transactionsIcon
    }
  }
}, {
  tabBarOptions: {
    showIcon: true,
    showLabel: false,
    activeTintColor: Colors.purple,
    inactiveTintColor: Colors.gray
  }
})

export default createAppContainer(TabNavigator)

Each of the above routes is a screen or stack of its own. The stacks are structured similarly to HomeStack above except that we use headers for some of the screens.

Individual Stack Components in Tab Navigator: ChatStack

The header items we use are defined in navigation Options which is built into react-navigation.

I've created my own custom <BackArrow /> component for navigating back and passed it the navigation prop and all of the navigation actions that come with it.

The initial ChatListScreendoesn't have a header, but because we defined a header for all of our screens in default Navigation Options at the bottom, we needed to explicitly set this screen to not have one.

For the title in each header, I'm passing it the name of the person the user is corresponding with in the chat via navigation using navigation.getParam, and failing that, setting a backup default option. You can also just set it to a string.

file: OurApp/app/navigation/ChatStack.js

import { createStackNavigator } from 'react-navigation'
import React from 'react'
import BackArrow from './components/BackArrow'
import ChatListScreen from '../containers/ChatListScreen'
import ChatScreen from '../containers/ChatScreen'
import ReviewInvoiceScreen from '../containers/ReviewInvoiceScreen'
import PaymentFormScreen from '../containers/PaymentFormScreen'
import CreateInvoiceScreen from '../containers/CreateInvoiceScreen'

const ChatStack = createStackNavigator(
  {
    ChatListScreen: {
      screen: ChatListScreen,
      navigationOptions: {
        header: null
      }
    },
    ChatScreen,
    ReviewInvoiceScreen,
    PaymentFormScreen,
    CreateInvoiceScreen
  }, {
    defaultNavigationOptions: ({ navigation }) => ({
      initialRoutName: 'ChatListScreen',
      headerMode: 'float',
      headerLeft: <BackArrow navigation={navigation} />,
      title: navigation.getParam('correspondentName', 'Messages')
    })
  }
)

export default ChatStack
Individual Stack Components in Tab Navigator: TransactionStack
import { createStackNavigator } from 'react-navigation'
import React from 'react'
import TransactionsBackArrow from './components/TransactionsBackArrow'
import TransactionsListScreen from '../containers/TransactionsListScreen'
import TransactionScreen from '../containers/TransactionScreen'

const TransactionStack = createStackNavigator(
  {
    TransactionsListScreen: {
      screen: TransactionsListScreen,
      navigationOptions: {
        header: null
      }
    },
    TransactionScreen: {
      screen: TransactionScreen,
      navigationOptions: ({ navigation }) => ({
        headerLeft: <TransactionsBackArrow navigation={navigation} />
      })
    }
  }, {
    initialRoutName: 'TransactionsListScreen',
    headerMode: 'float'
  }
)

export default TransactionStack
Navigating Between Screens

In components, in order to explicitly move from screen to screen (as opposed to using headers to navigate back), use the navigation prop and the navigation action.

this.props.navigation.navigate('TransactionScreen') 

This can commonly be called in an onPress() function.

Below you can see where the corresponding name is being passed through navigation to be used in ChatStack screen headers. You can also navigate to different stacks this way.

onPressChat = (correspondentName) => () => {
  this.props.navigation.navigate( 'ChatScreen', { correspondentName } )
}
Conclusion

Just an example of the mixed bag of features we use in practice and a simple, yet robust navigation system for mobile apps.
