Open Street Map Reverse GeoCoding

A free reverse geocoding service.

This library can be used to get location information from latitude and longitude for free. To get faster results, it is possible to enable the cache feature to store request results. This allows to reduce the number of API calls. It uses the OSM fundation API: https://wiki.osmfoundation.org/wiki/Main_Page

Open Street Map Reverse GeoCoding is a free service. Use it with moderation.

Installation

To install Open Street Map Reverse GeoCoding, run the following command:

yarn add open-street-map-reverse-geo-node-client

or

npm install open-street-map-reverse-geo-node-client --save

Stop Callbacks! Use Promises

This library does not use callbacks. Use promises instead.

Use the library with TypeScript

( see src/tests/index.test.ts file )

import { ReverseGeocoder } from  '.';

const  geo  =  new  ReverseGeocoder()
const result = await geo.getReverse('0','0')

The response:

{
    placeId:  '91511633',
    displayName:  'Opéra Municipal, Place de Jaude, Bonnabaud, Clermont-Ferrand, Puy-de-Dôme Auvergne-Rhône - Alpes, France métropolitaine, 63037, France',
    lat:  '45.77755365',
    lng:  '3.08255435728528',
    address:
    { 
	    theatre:  'Opéra Municipal',
	    pedestrian:  'Place de Jaude',
	    suburb:  'Bonnabaud',
	    city:  'Clermont-Ferrand',
	    county:  'Clermont-Ferrand',
	    state:  'Auvergne-Rhône-Alpes',
	    country:  'France',
	    postcode:  '63037',
	    countryCode:  'fr'
    },
    fromCache :  false
}

Use the library with JavaScript

const Geo = require('./dist')

const reverse = new Geo.ReverseGeocoder()

reverse.getReverse('45.777210', '3.082520')
	.then((location)=>{console.log(location)})
	.catch(err=>{console.error(err)})

Enable cache

Cache is enabled by default. To disable this option:

geo.disableCache()

Configure

You can configure your reverse geocoder instance.

const fakeGeo = new ReverseGeocoder({
	cacheIsEnabled : false, // Enable or disable cache
	callApi : false, // Set to true for your tests
	maxCacheSize : 200 // Number of elements saved in memory
})

Mock

If you want to run your test without calling API you can configure your reverse geocoder instance.

const fakeGeo = new ReverseGeocoder({
	cacheIsEnabled : false,
	callApi : false
})

Run tests

yarn run test

or

npm run test
