ags-walk

Walk the folders of an ArcGIS Server Rest API and return all the services as an array

about

ArcGIS Server is GIS software used by many federal, state, and municipal governments and organizations to publish web-enabled GIS data. ArcGIS Server uses the GeoServices API. This module walks the services and folders of the root GeoServices API for a given URL and returns all services and service types in an array. This could be used to create a repository of dataset names from one or more ArcGIS Server REST URLs.

Links to each dataset URL can be made by concatenating the root GeoServices URL with the dataset item and dataset type. For example, if the root URL is http://sampleserver6.arcgisonline.com/arcgis/rest/services and one of the datasets in the array is { name: '911CallsHotspot', type: 'MapServer' } the full URL to the service is http://sampleserver6.arcgisonline.com/arcgis/rest/services/911CallsHotspot/MapServer.

With Node v8.2.0+ it is not necessary to install ags-walk. You can run:

npx ags-walk <server-url> [options]

See example and available options by entering

npx ags-walk -h

install

To use as a dependency in a Node.js library you can install ags-walk by running:
