extract-jsonld.js

Simple utility for extracting JSON-LD data from given URL

Usage

// extract :: String -> Future e Object
const extract = require('@baethon/extract-jsonld')

// start extraction
extract('http://some.site/with-embeded-jsonld').fork(
  console.warn,
  jsonld => {}
)

// or convert Future to promise
const jsonld = await extract('http://some.site/with-embeded-jsonld').promise()

How it works

The idea is simple: load JSDOM document find the right script and JSON.parse its contents.

Whole thing is wrapped inside Future monad. So the process will start after calling fork() or promise() methods.

Script will fail when:

• fails to load JSDOM
• fails to find script tag
• fails to parse contents of the script
