A CKAN API wrapper in typescript for consuming data.
Just instantiate a CkanApi class with a proper URL not including anything else.
For example, in their test environment, the url is:
const ckan: CkanApi = new CkanApi("https://demo.ckan.org");With that instance at hand, you can simply call:
await ckan.siteRead();and it yields
trueyou can also list the packages by calling:
await ckan.listPackages();and it yields
["sample-dataset-1", "test_dataset", ...]The most used and powerful request is for a package. The response includes everything needed for data ingestion:
await ckan.getPackage("sample-dataset-1");and it yields
