Getting Started

Once you’ve set up your development environment, created a new React Native project, and installed the CedarMaps SDK for React Native, you’re ready to initialize a map in your App.js file.

First, you’ll import the components that you will need. This includes components from React, React Native, and CedarMaps.

To display a map you’ll need CedarMaps credentials (clientID and clientSecret). CedarMaps uses an access token generated from these to associate requests to API resources with your account.

Use the CedarMaps Map component, which is basically an extended MapView component, to initialize your map. The Map component will add a map to the view, and you can add props to specify some parameters for the map such as style and camera.

Here’s a sample code to display a map:

import React from 'react';
import {
  StyleSheet,
  StatusBar,
  View
} from 'react-native';

import CedarMaps from '@cedarstudios/react-native-cedarmaps';

const App: () => React$Node = () => {
  return (
    <>
      <StatusBar barStyle="dark-content" />
      <CedarMaps.Map
        style={styles.container}
        clientId={"YOUR_CLIENT_ID"}
        clientSecret={"YOUR_CLIENT_SECRET"}
        mapStyle={"style://streets-light"}
        >
          <CedarMaps.Camera
            zoomLevel={15}
            centerCoordinate={[51.4093, 35.7546]}
          />  
      </CedarMaps.Map>
    </>
  );
};

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

export default App;

Other possible values for mapStyle are:

Vector Tiles (Recommended)

• style://streets-light
• style://streets-dark

Raster Tiles

• style://streets-light-raster
