Query the OpenStreetMap Overpass API.
npm install @derhuerst/query-overpassQuery the OpenStreetMap Overpass API. Yet another implementation, because it
- is isomorphic (works in the browser)
- is lightweight (doesn't contain any sophisticated parser)
- uses p-retry to resend requests
Other alternatives for you to evaluate:
- query-overpass and a fork @sriharithalla/query-overpass
- idris-overpass and idris-overpass-browser
!ISC-licensed
``shell`
npm install @derhuerst/query-overpass
Pass in a string of Overpass QL. Returns a Promise that will resolve with an array of elements.
`js
const queryOverpass = require('@derhuerst/query-overpass')
queryOverpass(
[out:json][timeout:25];
node(3378340880);
out body;)`
.then(console.log)
.catch(console.error)
`js`

Note: The Overpass API does not support extended Overpass Turbo queries, as they are an Overpass Turbo-specific feature.
To use make requests from a web site, enable CORS using the fetchMode option:
`js`
queryOverpass(query, {fetchMode: 'cors'})
To use @derhuerst/query-overpass with a custom Overpass API endpoint, use the endpoint option:
`js`
queryOverpass(query, {endpoint: 'https://overpass.example.org'})
- osm-build-query – Build a query for the OSM Overpass API that retrieves all elements within the bounding feature.
- osm-flatten-relation – Resolve an OpenStreetMap relation recursively.
