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

   $ 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.

#### `{ 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.

**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
```js
createMapLink({ provider: 'apple', query: 'Yosemite National Park' });

Search query near coordinates (lat/lng)

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

Get directions from start to end using addresses

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

Get directions from here

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

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

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

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

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

Get public transit directions from start to end

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

Display with different base map options

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

Display centered around coordinates, really zoomed in

createMapLink({ 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.
