react-native-open-maps

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

react-native-open-maps works by creating a universal map link for either Apple, Google, and Yandex 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 different map applications

Usage

1. Install the repository

   1$ npm install --save react-native-open-maps

2. Add an import to the top of your file

   1import openMap from 'react-native-open-maps';

3. Put it all together

   1import React, { Component } from 'react';
   2import { Button } from 'react-native';
   3import openMap from 'react-native-open-maps';
   4
   5export default class App extends Component {
   6  _goToYosemite() {
   7    openMap({ latitude: 37.865101, longitude: -119.538330 });
   8  }
   9
   10  render() {
   11    return (
   12      <Button
   13        color={'#bdc3c7'}
   14        onPress={this._goToYosemite}
   15        title="Click To Open Maps 🗺" />
   16    );
   17  }
   18}

4. BONUS: You can also create delayed functions for more of that 1 - 1 mapping flavor 🍦.

1import { createOpenLink } from 'react-native-open-maps';
2
3const yosemite = { latitude: 37.865101, longitude: -119.538330 };
4const openYosemite = createOpenLink(yosemite);
5const openYosemiteZoomedOut = createOpenLink({ ...yosemite, zoom: 30 });
6
7const facebookHQ = { latitude: 37.4847, longitude: 122.1477 };
8const openFacebookHQ = createOpenLink(facebookHQ);
9
10// Condensed for Readability...
11    render() {
12        return (
13          <Button
14            color={'#bdc3c7'}
15            onPress={openYosemite}
16            title="Go to Yosemite 🏔" />
17          <Button
18            color={'#bdc3c7'}
19            onPress={openFacebookHQ}
20            title="Go to Facebook HQ 🕋" />
21        );

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.

{ createQueryParameters(options) }

Creates the query parameters for the designated maps provider. Useful if you want to override the base url and perform logic to override it with a native base URL.

options

Properties	Type	Description	Example	Map Support
latitude	number	The latitude	37.865101	All
longitude	number	The longitude	-119.538330	All
zoom	number	The zoom level, only works with latitude and longitude	18 Default: 15	All
provider	string [google,apple,yandex]	If no provider set, it will determine according to Platform.OS	apple	N/A
query	string	Will act according to the map used. Refer to query property	"Yosemite Trail"	All
queryPlaceId	string	Will query by Place ID.	ChIJgUbEo8cfqokR5lP9_Wh_DaM	Google
travelType	enumeration : [drive, walk,public_transport]	Use this parameter in conjunction with start and end to determine transportation type. Default is drive	"drive"	All
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". See Apple, Google and Yandex docs for more details on how to define geolocations.	"New York City, New York, NY"	All
end	string that geolocation can understand.	The end location that can be interpreted as a geolocation. See Apple, Google and Yandex docs for more details on how to define geolocations.	"SOHO, New York, NY"	All
waypoints	array: [address, address]	Define intermediate addresses between a route.	["San Jose, California", "Campbell, California"]	Apple (v16+) and Google
endPlaceId	string	End destination with the use of a place ID that uniquely identifies a places.	ChIJgUbEo8cfqokR5lP9_Wh_DaM	Google
navigate	boolean	This is only specific for Google. Yandex and Apple maps will provide directions if a start and end is provided.	true	Google
mapType	enum: [standard, satellite, hybrid, transit]	Specifies base map type. Note, hybrid is the satellite map with a transit layer, where as transit is the standard roadmap with a transit layer.	"hybrid"	All, except Yandex does not support "hybrid"

Note:

• Combining query with latitude and longitude will override the query parameter.
• Yandex Maps does not support building routes from current location.

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

Examples

Search by query

1createMapLink({ provider: 'apple', query: 'Yosemite National Park' });

Search query near coordinates (lat/lng)

1createMapLink({ provider: 'apple', query: 'Coffee Shop', latitude: 10.02134, longitude: -29.21322 })

Get directions from start to end using addresses

1createMapLink({ provider: 'yandex', start: '1 Infinite Loop, Cupertino, CA', end: '1600 Amphitheatre Pkwy, Mountain View, CA' })

Get directions from here

1createMapLink({ provider: 'google', end: 'New York City, NY' })

Get directions from here with additional stops (Apple or Google only)

1createMapLink({ provider: 'google', end: 'East Brunswick, NJ' })

Get directions by walking with a hybrid view (satellite and transit)

1createMapLink({ provider: 'google', end: 'New York City, NY', travelType: 'walking', mapType: 'hybrid' })

Get public transit directions from start to end

1createMapLink({ provider: 'google', start: 'SoHo, Manhattan, New York, NY', end: 'Times Square, Manhattan, NY', travelType: 'public_transportation' })

Display with different base map options

1createMapLink({ provider: 'apple', query: 'hiking trails', mapType: 'satellite' })

Display centered around coordinates, really zoomed in

1createMapLink({ provider: 'yandex', latitude: 10.02134, longitude: -29.21322, zoom: 20 })

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. This will set a pin with label set to the query value.
• 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.
• Yandex Maps: If latitude and longitude is provided, this will place a point to show the accurate location. If no latitude or longitude is provided, it will center map to closest query match.
