OverpassFrontend

A JavaScript (NodeJS/Browser) library to easily access data from OpenStreetMap via Overpass API. The objects can directly be used with LeafletJS or exported to GeoJSON. Data will be cached in the browser memory (persistent caching in LocalStorage or so may be added in the future).

INSTALLATION

npm install --save overpass-frontend

DOCUMENTATION

Find documentation in doc. You can re-generate the documentation with npm run doc.

EXAMPLE

const OverpassFrontend = require('overpass-frontend')
 
// you may specify an OSM file as url, e.g. 'test/data.osm.bz2'
const overpassFrontend = new OverpassFrontend('//overpass-api.de/api/interpreter')
 
// request restaurants in the specified bounding box
overpassFrontend.BBoxQuery(
  'nwr[amenity=restaurant]',
  { minlat: 48.19, maxlat: 48.20, minlon: 16.33, maxlon: 16.34 },
  {
    properties: OverpassFrontend.ALL
  },
  function (err, result) {
    console.log('' + result.tags.name + ' (' + result.id + ')')
  },
  function (err) {
    if (err) { console.log(err) }
  }
)

cd overpass-frontend
npm install
 
# Initialize database for unit tests (ignore messages because of missing nodes/ways) 
# replace /exec/path by the location where you installed osm3s 
init_osm3s.sh test/data.osm.bz2 test/data/ /exec/path --meta
 
# Run unit tests 
npm run test
