Smart Mapbox Turn-By-Turn Routing Based on Real-Time Traffic for React Native

React Native Mapbox Navigation

A navigation UI ready to drop into your React Native application.

Features

• A full-fledged turn-by-turn navigation UI for iPhone, iPad, and CarPlay that’s ready to drop into your application
• Professionally designed map styles for daytime and nighttime driving
• Worldwide driving, cycling, and walking directions powered by open data and user feedback
• Traffic avoidance and proactive rerouting based on current conditions in over 55 countries
• Natural-sounding turn instructions powered by Amazon Polly (no configuration needed)
• Support for over two dozen languages

Installation Requirements

Before installing the SDK, you will need to gather the appropriate credentials. The SDK requires two pieces of sensitive information from your Mapbox account. If you don’t have a Mapbox account: sign up and navigate to your Account page. You’ll need:

• A public access token: From your account’s tokens page, you can either copy your default public token or click the Create a token button to create a new public token.
• A secret access token with the Downloads:Read scope.

1. From your account’s tokens page, click the Create a token button.
2. From the token creation page, give your token a name and make sure the box next to the Downloads:Read scope is checked.
3. Click the Create token button at the bottom of the page to create your token.
4. The token you’ve created is a secret token, which means you will only have one opportunity to copy it somewhere secure.

Installation

npm install @homee/react-native-mapbox-navigation

Read the iOS specific instructions below before running pod install.

iOS Specific Instructions

Make sure your react native project has an Objective-C bridging header for swift. If you don’t have a bridging header you can follow these steps here below in the dropdown.

Create an Objective-C bridging header

Place your secret token in a .netrc file in your home directory that contains this:

machine api.mapbox.com
login mapbox
password <INSERT SECRET TOKEN>

Place your public token in your project’s Info.plist and and add a MGLMapboxAccessToken key whose value is your public access token.

Now you are ready to install the cocoapod:

cd ios && pod install

If you are experiencing a “multiple commands produce” build error in your Xcode project then you will need to add this entry below to the top of your ios podfile:

install! 'cocoapods', :disable_input_output_paths => true

For more information you can read the docs provided by Mapbox.

Android Specific Instructions

Place your secret token in your android app’s top level gradle.properties file:

MAPBOX_DOWNLOADS_TOKEN=SECRET_TOKEN_HERE

Open up your project-level build.gradle file. Declare the Mapbox Downloads API’s releases/maven endpoint in the repositories block.

allprojects {
    repositories {
        maven {
            url 'https://api.mapbox.com/downloads/v2/releases/maven'
            authentication {
                basic(BasicAuthentication)
            }
            credentials {
                // Do not change the username below.
                // This should always be `mapbox` (not your username).
                username = "mapbox"
                // Use the secret token you stored in gradle.properties as the password
                password = project.properties['MAPBOX_DOWNLOADS_TOKEN'] ?: ""
            }
        }
    }
}

Gradle

Place your public token in your project’s android/app/src/main/AndroidManifest.xml

<!-- This should be a child of the application tag -->
<meta-data android:name="MAPBOX_ACCESS_TOKEN"
    android:value="PUBLIC_TOKEN_HERE" />

XML

For more information you can read the docs provided by Mapbox.

How native is React Native? | React Native vs Native App Development

If you are undertaking a mobile app development for your start-up or enterprise, you are likely wondering whether to use React Native. As a popular development framework, React Native helps you to develop near-native mobile apps. However, you are probably also wondering how close you can get to a native app by using React Native. How native is React Native?

In the article, we discuss the similarities between native mobile development and development using React Native. We also touch upon where they differ and how to bridge the gaps. Read on.

A brief introduction to React Native

Let’s briefly set the context first. We will briefly touch upon what React Native is and how it differs from earlier hybrid frameworks.

React Native is a popular JavaScript framework that Facebook has created. You can use this open-source framework to code natively rendering Android and iOS mobile apps. You can use it to develop web apps too.

Facebook has developed React Native based on React, its JavaScript library. The first release of React Native came in March 2015. At the time of writing this article, the latest stable release of React Native is 0.62.0, and it was released in March 2020.

Although relatively new, React Native has acquired a high degree of popularity. The “Stack Overflow Developer Survey 2019” report identifies it as the 8th most loved framework. Facebook, Walmart, and Bloomberg are some of the top companies that use React Native.

The popularity of React Native comes from its advantages. Some of its advantages are as follows:

• Performance: It delivers optimal performance.
• Cross-platform development: You can develop both Android and iOS apps with it. The reuse of code expedites development and reduces costs.
• UI design: React Native enables you to design simple and responsive UI for your mobile app.
• 3rd party plugins: This framework supports 3rd party plugins.
• Developer community: A vibrant community of developers support React Native.

Why React Native is fundamentally different from earlier hybrid frameworks

Are you wondering whether React Native is just another of those hybrid frameworks like Ionic or Cordova? It’s not! React Native is fundamentally different from these earlier hybrid frameworks.

React Native is very close to native. Consider the following aspects as described on the React Native website:

• Access to many native platforms features: The primitives of React Native render to native platform UI. This means that your React Native app will use many native platform APIs as native apps would do.
• Near-native user experience: React Native provides several native components, and these are platform agnostic.
• The ease of accessing native APIs: React Native uses a declarative UI paradigm. This enables React Native to interact easily with native platform APIs since React Native wraps existing native code.

Due to these factors, React Native offers many more advantages compared to those earlier hybrid frameworks. We now review them.
