# query-overpass
**Query the [OpenStreetMap](https://www.openstreetmap.org/) [Overpass](https://overpass-api.de) API.** Yet another implementation, because it
- is isomorphic (works in the browser)
- is lightweight (doesn't contain any sophisticated parser)
- uses [`p-retry`](https://github.com/sindresorhus/p-retry) to resend requests
Other alternatives for you to evaluate:
- [`query-overpass`](https://github.com/perliedman/query-overpass) and a fork [`@sriharithalla/query-overpass`](https://github.com/SrihariThalla/query-overpass)
- [`idris-overpass`](https://github.com/idris-maps/idris-overpass) and [`idris-overpass-browser`](https://github.com/idris-maps/idris-overpass-browser)

## Installing
```shell
npm install @derhuerst/query-overpass
```
## Usage
Pass in a string of [Overpass QL](http://wiki.openstreetmap.org/wiki/Overpass_API/Overpass_QL). Returns a [`Promise`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/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](https://wiki.openstreetmap.org/wiki/Overpass_turbo/Extended_Overpass_Turbo_Queries), as they are an [Overpass Turbo](https://overpass-turbo.eu)-specific feature.
To use make requests from a web site, enable [CORS](https://developer.mozilla.org/en-US/docs/Web/HTTP/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'})
```
