RDF, Typescript and Deno - Part 3a: all ahead stop
Believing I had supernatural powers
I slammed into a brick wall
(Paul Simon - Gumboots)
I had hoped to get Part 3 of this mini-series on RDF, Typescript and Deno
out by now. The concepts aren’t hard to explain, and the code isn’t that
complicated. But what has proved to be extremely complicated is getting
the NPM library rdflib.js to import into my code.
There are various ways to use NPM modules in a Deno app. I’ve tried various approaches. None have worked so far, but the furthest I’ve got is:
// rdf-generation.ts
import { Namespace } from 'https://dev.jspm.io/npm:rdflib@2.2.7/esm'
But when I try to cache the import:
$ deno --unstable cache rdf-generation.ts

I think I’m going to have to seek some help!
