ckan-ts

ckan-ts is a fully tested and documented TypeScript wrapper for retrieving data from v3 CKAN APIs asynchronously. Its main aim is to provide parsed outputs using a coherent and consistent vocabulary across all resource types, and handle non-standard data provided by different organizations.

Usage

Install ckan-ts with npm i ckan-ts or yarn add ckan-ts.

Using ckan-ts is very simple. For instance, the following checks whether or not a site is functional, and retrieves its first 100 datasets if it is:

import CKAN from "ckan-ts";
const parser = new CKAN("https://demo.ckan.org/api/3/");
const isAvailable = await parser.available();
if(isAvailable){
	const datasets = await parser.datasets({limit: 100});
}

For the most part, ckan-ts is intended to retrieve data from unauthenticated endpoints. However, you can also pass it headers to use throughout, i.e.

const parser = new CKAN("https://demo.ckan.org/api/3/", {
	requestOptions: {
		headers: {} // the desired http headers go here
	}
});
