# Esri Leaflet GP
> an Esri Leaflet plugin for interacting with geoprocessing services published with ArcGIS Server and the analysis services hosted in ArcGIS Online.
Esri Leaflet GP relies on the minimal [Esri Leaflet](https://github.com/Esri/esri-leaflet) Core which handles abstraction for requests and authentication when necessary.
## Demos
Note that the latest version of this plugin requires a minimum of esri-leaflet [2.0.0](https://github.com/Esri/esri-leaflet/releases/tag/v2.0.0).
The demos below show the plugin in action
* [calculate a drivetime polygon](http://esri.github.io/esri-leaflet/examples/gp-plugin.html)
* [generate an elevation profile](https://jgravois.github.io/esri-leaflet-gp/elevation.html)
* [route to the closest facility](https://jgravois.github.io/esri-leaflet-gp/closest-facility.html)
* [solve a vehicle routing problem](https://jgravois.github.io/esri-leaflet-gp/demos/vrp.html)
## Example
```html
gp drivetime
body {
margin:0;
padding:0;
}
#map {
position: absolute;
top:0;
bottom:0;
right:0;left:0;
}
#info-pane {
position: absolute;
top: 10px;
right: 10px;
z-index: 10;
padding: 1em;
background: white;
}
document.getElementById('info-pane').innerHTML = 'click on the map to calculate 5 and 10 minute drivetimes';
var map = L.map('map').setView([40, -74.2], 12);
L.esri.basemapLayer('NationalGeographic').addTo(map);
var gpService = L.esri.GP.service({
url: "https://sampleserver1.arcgisonline.com/ArcGIS/rest/services/Network/ESRI_DriveTime_US/GPServer/CreateDriveTimePolygons",
useCors:false
});
var gpTask = gpService.createTask();
gpTask.setParam("Drive_Times", "1 2");
var driveTimes = L.featureGroup();
map.addLayer(driveTimes);
map.on('click', function(evt){
driveTimes.clearLayers();
gpTask.setParam("Input_Location", evt.latlng)
gpTask.run(driveTimeCallback);
});
function driveTimeCallback(error, response, raw){
driveTimes.addLayer(L.geoJson(response.Output_Drive_Time_Polygons));
}
```
## API Reference
### [`L.esri.GP.Service`](http://esri.github.io/esri-leaflet/api-reference/services/gp-service.html)

## Development Instructions
1. [Fork and clone Esri Leaflet GP](https://help.github.com/articles/fork-a-repo)
2. `cd` into the `esri-leaflet-gp` folder and install the dependencies with `npm install`
3. Run `npm start` from the command line. This will compile minified source in a brand new `dist` directory, launch a tiny webserver and begin watching the raw source for changes.
4. The example at `debug/sample.html` *should* 'just work'
5. Make your changes and create a [pull request](https://help.github.com/articles/creating-a-pull-request)
## Dependencies
Esri Leaflet GP relies on the minimal Esri Leaflet Core which handles abstraction for requests and authentication when necessary. You can find out more about Esri Leaflet from the [Esri Leaflet Quickstart](http://esri.github.io/esri-leaflet/examples/).
