# extract-jsonld.js
Simple utility for extracting JSON-LD data from given URL
# Installation
```bash
npm i @baethon/extract-jsonld
```
# Usage
```js
// 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](https://github.com/jsdom/jsdom) document find the right script and `JSON.parse` its contents.
Whole thing is wrapped inside [Future](https://github.com/fluture-js/Fluture) 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
