    featureservice

    Get all features from an Esri Feature Service

    npm travis Greenkeeper badge

    A little module that extracts every feature from an Esri Feature Service. The real power in this module is that it's designed to page over a service and extract every single feature no matter what ArcGIS Server version the data is hosted on.

    Install

    npm install featureservice
    

    Usage

    var FeatureService = require('featureservice')
     
    // a url to a feature service
    var url = 'http://....../FeatureServer/0'
     
    var service = new FeatureService(url, options)
    service.pages(function (err, pages) {
    /* will give you links to all pages of data in the service*/
    })

    Options

    An object passed as the second parameter when initializing a service

    • layer: the layer index to use
    • size: the maximum page size when requesting features
    • concurrency: the maximum concurrency for requesting features from a single server
    • timeOut: the amount of time to wait with no response before cancelling a request
    • logger: An object with a log method that takes a level and a message e.g. a Winston instance

    })
