Archaeologist

A thin Node.js client for working with the ESRI ArcGIS Server REST API.

The ESRI ArgGIS Server Rest API is somewhat confusing. Archaeologist seeks to help.

Example Usage

Basic usage:

var Arc = require('archaeologist');
var arc = new Arc({
  apiHost: 'http://host.com',
  apiPathBase: '/path/to/service'
});

arc.get({where: "SOMEFIELD='SomeValue'"}, function (error, data) {
  /*
  performs a get request to:
  http://host.com/path/to/service?where=SOMEFIELD='SomeValue'&returnCountOnly=false&returnIdsOnly=false&returnGeometry=false&outSR=4326&outFields=*&f=json
  */

  if (error) return error;
  console.log(data);
});

Overriding default response options:

var Arc = require('archaeologist');
var arc = new Arc({
  apiHost: 'http://host.com',
  apiPathBase: '/path/to/service'
});

arc.get({
  where: "SOMEFIELD='SomeValue'",
  returnCountOnly: true,
  outFields: ['somefield']
}, function (error, data) {
  /*
  performs a get request to:
  http://host.com/path/to/service?returnCountOnly=true&returnIdsOnly=false&returnGeometry=true&maxAllowableOffset=&outputSpatialReference=&outFields=somefield&where=SOMEFIELD='SomeValue'&f=json
  */

  if (error) return error;
  console.log(data);
});

Configuration

View settings:

arc.settings

Specifying new settings on instantiation:

var arc = new Arc({
  apiHost: 'http://host.com',
  apiPathBase: '/path/to/service',
  defaultResultOptions: {
    outFields: ['field', 'anotherField'],
  }
});

View original, default settings:

arc.defaultSettings

/*
{
  apiHost: undefined,
  apiPathBase: undefined,
  defaultResultOptions: {
    returnCountOnly: false,
    returnIdsOnly: false,
    returnGeometry: false,
    maxAllowableOffset: '',
    outSR: '4326',
    outFields: '*',
    f: 'json'
  }
}
