react-native-open-maps

Travis David npm

🗺 A simple cross-platform library to help perform map actions to the corresponding device's map (Google or Apple Maps)

react-native-open-maps works by creating a deep link for either Apple maps or Google maps that can be used to open up the relevant map application. In order to maximize compatibility some platform specific parameters are omitted, but simplifies development efforts and ensures a smooth user experience.

Features

  • Open the map coordinates immediately
  • Create a delayed invoked function that will open the map
  • Create a string of the map link
  • Cross-compatible properties among both map applications

Usage

  1. Install the repository
    $ npm install --save react-native-open-maps
  2. Add an import to the top of your file
    import openMap from 'react-native-open-maps';
  3. Put it all together
    import React, { Component } from 'react';
    import { Button } from 'react-native';
    import openMap from 'react-native-open-maps';
    
    export default class App extends Component {
      _goToYosemite() {
        openMap({ latitude: 37.865101, longitude: -119.538330 });
      }
      
      render() {
        return (
          <Button
            color={'#bdc3c7'}
            onPress={this._goToYosemite}
            title="Click To Open Maps 🗺" />
        );
      }
    }
  4. BONUS: You can also create delayed functions for more of that 1 - 1 mapping flavor 🍦.
import { createOpenLink } from 'react-native-open-maps';

const yosemite = { latitude: 37.865101, longitude: -119.538330 };
const openYosemite = createOpenLink(yosemite);
const openYosemiteZoomedOut = createOpenLink({ ...yosemite, zoom: 30 });

const facebookHQ = { latitude: 37.4847, longitude: 122.1477 };
const openFacebookHQ = createOpenLink(facebookHQ);

// Condensed for Readability...
    render() {
        return (
          <Button
            color={'#bdc3c7'}
            onPress={openYosemite}
            title="Go to Yosemite 🏔" />
          <Button
            color={'#bdc3c7'}
            onPress={openFacebookHQ}
            title="Go to Facebook HQ 🕋" />
        );

API

default function open(options)

react-native-open-maps immediately opens the map of the coordinates and the settings

{ createOpenLink(options) }

Creates a delayed invoked function to open the map. This is useful for binding functions to onPress() in a succinct manner. Think of it like ... function openToMe() { open(coordinates) }

{ createMapLink(options) }

Creates the raw link for the map.

options

🔑 Italicize indicates optional

Properties Type Description Example
latitude number The latitude 37.865101
longitude number The longitude -119.538330
zoom number The zoom level, only works with latitude and longitude 18
Default: 15
provider string
[google,apple]
If no provider set, it will determine according to Platform.OS apple
query string Will act according to the map used. Refer to query property "Yosemite Trail"
travelType enumeration : [drive, walk,public_transport] Use this parameter in conjunction with start and end to determine transportation type. Default is drive "drive"
start string that geolocation can understand The start location that can be interpreted as a geolocation, omit if you want to use current location / "My Location". "New York City, New York, NY"
end string that geolocation can understand. The end location that can be interpreted as a gelocation. "SOHO, New York, NY"

Note: Combining query with latitude and longitude will override the query parameter.

Map Actions

To perform certain map actions refer these necessary parameters

  • Setting Directions: end, [ start , travelType ]
  • Display Map Around Coordinates: latitude + longitude, [ zoom ]
  • Query Map For Location: query
Query Property

The query behavior differs per platform:

  • Apple Maps: If latitude and longitude is provided, this will place a marker with the query as a label. If no latitude or longitude is provided, it will center map to closest query match.
  • Google Maps: Will override latitude and longitude if present and center map to closest query match. Without a query, you may however use <latitude>,<longitude> as a string value in the query to have a unnamed marker on the map.
