- 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.
1. From the token creation page, give your token a name and make sure the box next to the Downloads:Read scope is checked.
1. Click the Create token button at the bottom of the page to create your token.
1. 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.

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.

There are a few build settings in Xcode that are necessary. Make sure to set Don't Dead-strip Inits and Terms to YES and Dead Code Stripping to YES for all projects/targets.

You will also need to remove the entry "$(TOOLCHAIN_DIR)/usr/lib/swift-5.0/$(PLATFORM_NAME)" from Library Search Paths if it is present for your project target -

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

Add the UIBackgroundModes key to Info.plist with audio and location if it is not already present. This will allow your app to deliver audible instructions while it is in the background or the device is locked.

`
UIBackgroundModes

audio
location

`

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

`
machine api.mapbox.com
login mapbox
password
`

Add the following to your ios podfile -

`ruby
pre_install do |installer|
$RNMBNAV.pre_install(installer)
# any other pre install hooks here
end

post_install do |installer|
$RNMBNAV.post_install(installer)
# any other post install hooks here
end
`

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

If you are having an issue with your archive not showing up in organizer after archiving then you will need to open ios/Pods/Target Support Files/@react-native-mapbox-gl-mapbox-static/@react-native-mapbox-gl-mapbox-static-copy-dsyms.sh and comment out lines 85 thru 89 -

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

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.

`gradle
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'] ?: ""
}
}
}
}
`

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

`xml

android:value="PUBLIC_TOKEN_HERE" />
`

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

Usage

`jsx
import * as React from 'react';
import { StyleSheet, View } from 'react-native';
import MapboxNavigation from '@homee/react-native-mapbox-navigation';

export const SomeComponent = () => {
return (

origin={[-97.760288, 30.273566]}
destination={[-97.918842, 30.494466]}
shouldSimulateRoute
showsEndOfRouteFeedback
onLocationChange={(event) => {
const { latitude, longitude } = event.nativeEvent;
}}
onRouteProgressChange={(event) => {
const {
distanceTraveled,
durationRemaining,
fractionTraveled,
distanceRemaining,
} = event.nativeEvent;
}}
onError={(event) => {
const { message } = event.nativeEvent;
}}
onCancelNavigation={() => {
// User tapped the "X" cancel button in the nav UI
// or canceled via the OS system tray on android.
// Do whatever you need to here.
}}
onArrive={() => {
// Called when you arrive at the destination.
}}
/>

);
};

const styles = StyleSheet.create({
container: {
flex: 1,
},
});

Array that contains the longitude and latitude for the starting point.

[$longitude, $latitude]

#### destination (Required)

Array that contains the longitude and latitude for the destination point.

[$longitude, $latitude]

#### hideStatusView

Boolean that controls showing the StatusView (iOS only). This is the transparent black bar with the "Simulating Navigation" text shown in the above screenshot. Defaults to false.

#### onLocationChange

Function that is called frequently during route navigation. It receives latitude and longitude as parameters that represent the current location during navigation.

#### onRouteProgressChange

Function that is called frequently during route navigation. It receives distanceTraveled, durationRemaining, fractionTraveled, and distanceRemaining as parameters.

#### onError

Function that is called whenever an error occurs. It receives a message parameter that describes the error that occurred.
